Chris, so is the kit coming with canards?

ritewing
28th August 2015, 10:05 PM
The ones in the pre order will come with the foam pieces, I'm working on hardware development for the pivot, but I'm looking to also have some possible design help on the linkages. I just mounted one on my prototype aircraft, I'm going to be working on them in the next few weeks to get this somewhat dialed. I have a square carbon fiber tube with a round carbon fiber Rod in it.http://images.tapatalk-cdn.com/15/08/28/a121b7ef0cdd7d4dc45bd32668395680.jpghttp://images.tapatalk-cdn.com/15/08/28/94903c3d22b16263a96d9ac1af8b3f18.jpg

Canards is interesting. Will they be fixed, or linked to a servo for mixing with elevator or something? How will canards affect the handling and flight characteristics of the Drak?

Its actually a retty cool trade off. Now it is no longer a flying wing control wise. Plus the CG can now move forward and have a much wider range. A lot changes with this simple mod as I see it. Those look HUGE though IMHO but having never flown a Drak what the hell do I know.......LOL!! Nice Mod Chris. I like it. I might try that on my ZIII just to see what happens!! Or have you tried it already?

What kind of level flight speeds are we looking at with the SS motor setup you are testing out? Since we still have a couple months I may start working on a scratch build and may buy two sets and put one on it and the other on the drak whenever it ships out.

Just got an email saying the molds are going to be done by the 18th of this month and run just after, I should have samples here about a week earlier than I had thought.
I will be posting info as I receive it.

All is looking good, cant wait to get it in my hands.

I have seen about 85 to 90 knots flat out with the new motor combo.

6th September 2015, 02:57 PM
Awesome. I cannot wait to get my hands on one. I love my Z3 and Z60 but the Drak is gonna be the best of both worlds and I can see that being a serious combination. Go really long range and at the same time dive some mountains, carry a huge payload and then pack down at the end into something you can travel comfortably with. I don't need a long and short range plane any more, I need a Drak.

Some pix, it's rough, but not bad for poof of concept. This plane has been through the ringer when it comes to prototype testing. If I get a chance this week I'll see if I can get it up and get some video.http://images.tapatalk-cdn.com/15/09/06/02c4a73a049b987fcdfa657013ba5f4c.jpghttp://images.tapatalk-cdn.com/15/09/06/592c4694c8c03297b6a6a37ebbfe99c0.jpghttp://images.tapatalk-cdn.com/15/09/06/8ffb45845793860562d96ae680f2e309.jpg

As far as i can see all the electronics is meant to be installed within the main center section(fuse or side bays). Will there be enough separation between vTX, UHF rx and GPS or it make sense to think about moving some of those components to the tips of the wings? This would have impact on "break-apart-ability" though.

londonguy
7th September 2015, 10:55 AM
There are plenty of connectors you can use. I have vtx and UHF on the wings of my z3 and it breaks down exactly the same with a single 8pin connector in each wing.

I prefer the separation as I fly long range and it helps to give me a clean video and RC link.

But if you are just flying under 5-10 miles you don't really need it.

route81
7th September 2015, 11:22 AM
Chris, looking at the images those mobious/cam seem to be looking straight into the bench.
Is it because your're flying it so high alpha with the canards on?
Should we start thinking some kind of gimbal on the front (at least for tilt axis) to take real advantage of the full alpha range?

j.

ritewing
7th September 2015, 11:59 AM
I fly my cams pointed to where I have on 1/3 sky and 2/3 ground. I fly alot of mountains and valleys so 5 to 8 degrees of down is typical for me. You can mount the canard hardware on your fuse anywhere you see fit, these 1st batches will be coming with the foam pieces only, so it is up to the end user to make his own pivot section, I am working on developing a pivot section now, & I have a few ideas on how I want to make it serviceable and removable.

Tomstoy
7th September 2015, 12:52 PM
Chris, trying to figure out how to employ the canards. Would one mix canard operation to a certain elevator control stick input. Say, no canard output until say 25% elevator stick movement? Or would one just have them coupled with no mixing?

ritewing
7th September 2015, 01:03 PM
There's multiple ways to mix in the canards, I'm not worried about all of that in main flight, I'm looking to use this for mapping and to be able to drop it into a short landing zone in a tight area, so I will employ my canards with a little bit of up while its and stabilized and the stabilized mode will automatically drop the elevons to counter the nose rising up, thus creating flap effect so we can bring it in at a very slow clip in tight areas. There will be many people working on tweaking the way this works as it comes out. Then you can dial it in to how you want it to work. I'm using as a tool to slow the aircraft down.

Tomstoy
7th September 2015, 03:26 PM

Will keep a close eye on what you post up as mine will primarily be used mountain bombing. Landing in a tight area is very desirable.

Ok, thanks. So you're actually have your vTX and Rx on the tips, not the antenna extensions. I think I'll do the same.

I have my set up the same as Chris does using the center bays(Z3); no problems going out 7 miles on 200mW and Dragon Link.

ritewing
8th September 2015, 11:03 AM
Ya, I have also been way out to 13 mi on 400 MW RMRC 2.4 VTX on Video aerial clover, then on the ground I have a 2.4 pepper box ant.
I have a cap filter on the power feeding my VTX and camera in the plane.
The setup is nothing special, its just simple and clean.

Hmerly
8th September 2015, 11:41 AM
Yeah, you don't really need to embed the antennas/vtx/rx into the wings on the z3. The side pockets or fuse work great for that. I never had issues going many miles out doing it this way. I think its enough separation. Maybe if you were trying to do a really long mission, but your problem is probably going to be battery rather than your link budgets. Only time I had trouble was when I was using EZUhf. Its finicky and I always had to adjust my wiring and had to constantly run the scanner to see if there were any issues with the frequency it runs at. Since switching to a different UHF system I've been able to pretty much put the plane in the air and never worry about losing control.

ritewing
9th September 2015, 06:15 PM
FYI guys, had 3 flights with the canard on today, first one was with them fixed, Cg was off bad , and so was incidence on the chord line.
It landed hard but was fine.
Second flight I added some nose weight and mixed the canard to the elevator 10 % it flew much better for about 2 mins but was a still off on the CG some and rates.
Landed and re adjusted.
3rd flight was flying for almost 5 mins and was stable at speed, but Cg was off still.

I was landing it and when it slowed on approach I tip stalled it and doinked it good.
Cg is still off, I made great progress and learned a lot.

The plane is the original proto with tons of flight on it, I learned a lot with damaging it to bad.

But at this point I think I will wait till I have the molded version here to do more testing, this will allow me to have the exacting info and jigs made so you guys can have an easy time taking what I learn and applying it.
It flew better each time and I see where the canard could be super cool.

Here is the pic of the new Ritewing SS 3515 950 kv. It has custom windings , custom shaft, custom built prop adapter, Japan bearings, custom rear shaft lock collar. This allows for a fast debris and damage inspection in the field of motor bell, magnet, windings.
And now no more slipping of a wrench on a hard to tighten collet prop adapter. This new adapter tighten on to a custom shaft with 2 4 mm set grubs. There is also a custom made prop nut that uses more of the thread for a non strip secure attachment of the prop. Now we have a UAV quality motor. http://images.tapatalk-cdn.com/15/09/28/2d0743efcd3e15a92a6ea6d474ebaa0e.jpghttp://images.tapatalk-cdn.com/15/09/28/2452a4c24aaeec00f0b5b24c8801e200.jpg

Those slots were intended on the Z3 for LED strips, so I suspect much the same here for the Drak. I used them on my Z3 for cable runs to the outboard VTX and the coax to the outboard UHF antenna- they worked real good for that. But I do hope these are also molded into the bottom of the wing, not just the top (on the Z3, they are only on the bottom). It makes for a very clean looking install.

So the elevons are EPP not wood like past Ritewing offerings. How do you feel the torsional stability will be maneuvering at speed, Chris?

BacklashRC
2nd October 2015, 12:46 PM
Torsional flex is a big concern for me as well. Foam elevons are also fragile (thin foam) and are prone to being dented easily. I will likely replace them with balsa...

My guess is that they will be included, because precut Coroplast covers have been included it has been in previous Ritewing kits. Keep in mind that if you don't like the look of the coroplast you can always cover it with sign vinyl or something similar.

Judging by the grooves in the elevons they are designed to accept some stiffening rods. I may still consider wooden ones but it's all good.

Man, this thing is looking beautiful. It's going to be the sexiest wing in the air by far. Great job, Chris. You hit a homerun.

What's your next project? :p

ritewing
2nd October 2015, 10:15 PM
As far as the control surfaces go, you can drop fiberglass in them and laminate them and they'll be stiff as a board, but I will also offer Wood if people want to use Wood as an upgrade, I have done elevons like this for some high performance planes and they work really well, but I had room in the mold so I figured I would go ahead and give it a try. The plane is silver, I might be able to get silver coroplast, but then when you fly the plane it will absolutely disappear in the sky. When I get the samples next week and build them I will let you guys know how the elevons fair.

I have three other projects I've been working on also for a while, let's get this Drak rolling, and we'll see how the other projects go. If the Drak goes really well it should allow me to bring a bunch of other aircraft out in this type of material, if it doesn't do well it will be a major struggle here in the future for us. I appreciate all the support thus far, taking this project on is a massive undertaking in many ways.

Here is a pic of the new Drak motor mount. It will take 28 and 35 mm motors, it also doubles as a efficient heat sink. The bottom of it encases it to protect the motor on any hard landings, it will not let the ground or rocks hit the rotating can of the motor. It puts the thrust line directly in the place it needs to be, the thrust angle will be nailed when you mount this in. You won't find this quality and design with any other model that I know of. Hey if you're going to push it you might as well push it real good!

Chris, are you going to do some build videos for Drak? I'm especially interested how to laminate its center section since it has some pretty complex shape.

ritewing
3rd October 2015, 12:54 PM
Yes Oleg, my answer to that is do it in pieces , small overlaps are not even visible.
I will also determine the best type and thickness of film to use, that alone make a huge difference . I will also see how the build goes without major lam, LE of wings ,fuse bottom and elevons , and plastidip for the added colors.

I'd forego laminating the center section but that's just me. Not only for the reasons you bring up but I just don't feel it's necessary.

I'll consider laminating the wings and I understand it adds some durability and helps with hangar rash and the little dings such but let's face it, in a good crash the wing is just going to break off at the root anyway regardless of lamination and or the nose will crumple significantly. I think I'm out on an island with that but I'm hoping to build it as light as possible for best flight characteristics, not best crash characteristics.

I think it's uncommon customer service for Chris to make multiple builds with varying thicknesses and degrees of lamination and report back to us. Can't say enough about all he's doing for us with this aircraft.

I'm so looking forward to reading the flight reports and seeing the videos from the hardcore pilots on here.

Don't get hung up on weight. Laminating isn't something you should skip on this airframe.

HFMan
3rd October 2015, 08:59 PM
Agreed.. It will make it stronger, smoother, and won't get filthy as easily.

Hoss
3rd October 2015, 09:33 PM
Agreed. The weight is negligible in comparison to the protection gained. Even for the long protruding nose - 2 thin spars properly glued and a covering of laminate will keep it intact if you decide to fly into something a little more dense than air. On my other wing, if I didn't have 2 coats of lam on it I wouldn't have a plane (x5). Lots of chances taken, few missed, some big... The Drak will get a single 5mil coat on my build. But totally worth it in my opinion. The first Drak video I saw months ago was of someone catching it in a tree. Wing split in half. A proper lam job would've saved that.

So, it'll be silver / gray? Is that just the prototype color or will that be production?

Maj.Duty
3rd October 2015, 11:29 PM
That's why I said I'm out on an island because I realize popular practice is to laminate, and everybody does it, and most people point to crash resistance. If all it does is add durability, again, I'll forgo lamination. Crashing is the rare exception or at least should be. I've got planes literally 19 years old I've never crashed and they still fly today. Of course watch now I'll bust up this one maiden flight.

Admit I didn't consider laminating making it smoother and I'll check out the EPP skin once it is in hand. And like I said I'm considering doing the wings but if crash durability is the main reason to do so, then I'm undeterred in my position.

Hoss
4th October 2015, 12:02 AM
My intentions initially were to smooth the poroussness of wire cut epp. It makes for a super slick, glass-like finish that most certainly contributes aerodynamiclly (at least in relation to the rough, pitted surface of burnt foam). This wing shouldn't have that being that it's molded though.The durability came into play when I decided it would be fun to come down out of the clouds and start flying an inch off the ground. It's also nice when traveling and stuffing in the car - not having to worry about dinging it up. But... Being that this is in pieces and not a single unit, the strength gain isn't going to be quite the same as with a solid wing.

Hmerly
4th October 2015, 01:06 AM
The weight saving won't make any bit of difference. However, the added durability, smoothed foam surface, and improved finish will most definitely be noticed. I think its silly to skip laminating to chase after a "light build" that doesn't matter in a plane this size. I don't think anyone will say your plane that's not laminated flies better than the one that is laminated. I bet someone will say the one that is laminated and isn't dinged up sure looks better than your bare plane.

Exactly! The trailing Drak tracked really well. No head shaking like a pit bull with a toy. Especially considering the speed.

And, you're correct about it being a plank, and their temperamental nature. Not that you would ever know it if you saw it fly in person. She flys so sweet! Couldn't tell you of any queries in handling but the speed envelope is wide.
She's an attention grabber.

So, I assume your prototype shows up for your final approval real soon?
If she meets your expectations when do you estimate they will ship?

You can mount the motor either direction, but then you defeat the whole purpose of being able to service the motor like I was trying to do, and the prop adaptor will only land one grub on the outer flat spot on the shaft.

The shaft is not symmetrical , it is 5 mm diam, but is meant to mount one direction.

Anything else OLEG,lol

Ok, make sense, being able to do a field service is always good.

But I see now - its completely another story.

ritewing
7th October 2015, 06:59 PM
Hi Oleg ,yes the Z3 is running higher rpm on a smaller prop. It also does not have this style motor mount, so mounting the prop closer to the mount on the shaft cuts down on vibes on the Z3.
I have seen vibrations on the z3 when the motor is mounted off the back of the Z3's mount.
This is not the same plane or motor mount.

Hi LVS , we also have major motor contamination issues , thus the reason to get the motor more industrialized and servicable. At this point we are still waiting on samples, the bad east coast weather has delayed their arrival. As soon as I see them and give aproval they will do the run of products. Then they will ship them here there after. It will depend on customs load and schedule at that point . I am told it can be as varying as 3 to 7 weeks. Of shipping time. We are anxious here to get them as you are. You all are the best for having the faith and patience in this big under taking. We really appreciate it.

12th October 2015, 12:44 AM
I think this is a great idea. A visual inspection and clean of the motor is good practise, but it's usually a pain in the ass and usually involves some silly tiny grub screw made with soft metal so after a few inspections your grub screw is rounded out and needs replacing.

This way you can inspect your motor before a big flight and know at least there isn't anything in there waiting to go wrong when you are 30k out.....

One question, Chris - can't see on a pictures, so do you still have those fiberglass, or something, tubes(like in Z3) under those foam caps?

I think those tubes on Z3 are really good idea, as I have another big wing which doesn't have those, and after a several hard landings/failed launches the fit is not that snug anymore so the wings don't sit tight.

I tacked them in the bottom with hot glue, then I put a small bead of group on each side of the spar tube. I am trying a few different things, I want to keep the weight down also. Here she is, this is how far I got tonight in about 4 hours. Completely spark up except for the top of the fuse fiberglass rod spars, you will use a combination of hot glue poop and gorilla on this whole plane .http://images.tapatalk-cdn.com/15/10/12/f0352ef3e9a0777c4f81dece765a62cb.jpghttp://images.tapatalk-cdn.com/15/10/12/2bf06183cb2d3071360eba9afedc2c9e.jpg

Just wondering- would there be much benefit to make those canards steerable?
I had a DIY delta wing with steerable canards and elevator authority was crazy. Ended up not using the mix with elevator for flying, but mixed inverted (front of canards looking down) with elevator up for landing. It slowed delta down for landing to nearly a hover, with throttle management it was going down like a swan. LOS was easy enough but to do so FPV cam's tilt or headtracker would be a must.

If you are registered with UThere Jim is contract bound to work with you on you Ruby(s), whether you move a Ruby you own or even purchase one privately from somebody else. Jim isn't taking any more orders from hobbyists is all. So, if you are registered Jim will be happy to work on getting your Ruby set up for the Drak, and if I know Jim, he'll be quite happy doing so. He hasn't forgone his commitment to existing customers.

I have a Ruby in my Ranger and love it. I also have a Vector just sitting around waiting for the Drak to arrive at my door.

I have flown many Autopilots, I will say the vector flys my planes way better.
The vector will fly your plane on its default settings, then tune from there, it is super easy.

You do not need to fly multiple times to get jim to tune it .
For fpv the vecotor has it all, a sweet OSD , sticks that do not change their designation.

Hell the vector even has its own power supply for its osd ,itself and filterd vid power for cams and vtx, that alone saves you from a spageti mess of wiring and extra 2 BEC that you will need with the ruby, the ruby looks unkept and is a jumble of wires.

The Vector is clean simple and 1/2 the cost and 80% less hastle tuning.

The vector will fly it in stabilized modes at very fast speeds, the ruby is not set up to do this.
So to pay that much for a ruby and to have to deal with some one else tuning itm I am not feeling it any more.

Jim is a great guy, he is busy doing non hobby stuff where the ruby can be better for.

But in my opinion if you want the best fpv flying performance then use the vector, get the airspedd sensor with it too.
I have 10 rubies here in a box if you want to buy one, I put vectors in evey plane I fly for FPV.

c5galaxy engineer

It would probably be a good time to throw this out and say I have a Vector I would sell. Its like new…….I think I even have it stored in the box it came in.

Well the Crossfire WILL work with a Vector as I have personally watched a beta tester take one out to 11 miles. Im not sure exactly what is not comparable with the Vector/Crossfire combo but is will be worked out I have no doubt. From what I have seen with the Crossfire so far
'better" is a pretty bold statement (lol) as that thing is full of magical wonder (to me anyway…..the things it can do!). I am very very curious to see what you have got going on there Chris!! Do you have any more vaguely vague hush hush details you can share? When is that due out? Hummmm……now I am at yet another FPV quandary. LMAO. Just take my credit card number and send me stuff!
I have to wonder if your new radio will work in the Cockpit ground station?!??!? I can't wait to launch a Drak off the top of it. As you probably know, we have flown a ZII and a Z3 launched from the top of it. They are great planes for cockpit/joystick flying!! They feel like your own Jet Fighter!!!

I can't say much on the new system right now, but for the capabilities of what it's going to be able to do will be a game changer, it also still uses 433, which will go farther than 900. It will have multiple channels so you can piggyback all kinds of stuff, when we're doing mapping and other things this is a must. but what it does on the ground station is the game changer for me . & I can't say what that is at this time

3m dual lock would be a better attachment material imo. Velcro gets shitty and loose after a while. Dual Lock stays tight and is virtually impossible to separate horizontally.

ritewing
15th October 2015, 11:47 PM
The strap velcro is a very very durable type compared to the standard velcro, and it will take a lot of attachment and un attachment for a long time. The dual lock is so strong that every time you and do it you will rip it off the aircraft. Ask me how I know. And if you put the hook side up on the aircraft you can always replace the fuzzy side, the hook side always stays good. I've also noticed on the dual lock after a while pieces start breaking off of it, it doesn't work good for a strap type situation that has lots of flex. We also don't need a lot of pulling strength on this, you only need to keep the Wing pulled towards the center of fuse, its not like they want to come off .

I have only flown the prototype so far in multiple sizes, I want to get this one up and flying before I add any other aspects of complexity like the canards to it. The wingspan is slightly changed all the sweep and the Wing area is the same, I know 99.9% where the CG needs to be but I want to get it dialed before I do anything else. What I'm good at is maidening and flying airplanes and tweaking them. This needs to be done before any autopilot system is engaged. I need a baseline to start from.
