Ill say. Ive never had a plane that required so little adjustments on the first flight.

What battery/motor/ESC are you using? Did you try any vertical yet?

Really awesome video Aaron! I love watching the shadow flying low like that! Really nice work. I can't wait to get mine (fingers crossed) :)

2x4000mah4s, ritewing 1300kv motor, 11x7 prop. I didn't try vertical on the maiden outage. Will soon though!

ritewing
4th April 2015, 12:36 PM
The motor is a protoype 2820 SS 1300, its not a crazy efficient setup, but its a perfect all around for speed power and efficiency.
Whats nice with 8000 to 10000 mah hr you can fly for crazy long times. I have been up for 40 mins on this setup.
If you want really long flights go about 700 to 800 kv on 5 or 6s 6000 to 7000.

You know Chris, you and your Drak, forcing me to change my world.


I've (almost) always scratch built my own planes, and stuck with 3S systems, all with a 25+ year old FM Futaba FP-7UHF single model radio.


This radio doesn't support elevon mixing, so it's either a mechanical mixer, or...


Taranis plus arriving Wednesday, I blame you Chris, as the Drak forced me into upgrading (Again, blame = THANK).


So, obviously I need to get some 4S packs... bigger plane, bigger motor, bigger prop. I need expand my experience, not a bad thing, but I blame you.


Then you're nice/generous enough to still offer the Drak to us, even if the KickStarter doesn't reach your goal, which is at a large personal expense to you!


And, I've seen on a lot of threads how good you are at supporting your customers, so I know if I have problems/need parts you'll be able to assist!

DAMN YOU!

What a beauty! I can't wait to get my hands on her....
But what do I do till August? I got all the electronics for the Drak on my desk right now.
I guess I'll build myself a FPV49 KFm in the meantime.

Brilliant. That video is about 100x more likely to get backers than the Ritewing Kickstarter video.

Looks like a great plane. Surprisingly agile for such a big wing. Nice stall test too.

It's very fast. What size batteries were you running? It seemed to land fairly fast- does it have a high stall speed or did you just land it hot because you know the airframe can take it?

aaron_gx
5th April 2015, 10:07 AM
Flew her again yesterday, and pulled vertical. It held straight vert for a good 10 seconds, then fell off to the side. Thats respectable for 3150g... :-) Pulls 89A on take off!!!

aaron_gx
5th April 2015, 10:14 AM
Lol, i landed fairly slowly i thought ;-) Im used to most flying wings that tipstall at slow speed, and that usually makes for a cartwheel landing. So i usually land quickly - watch my other vids lol

I was surprised to see the nose flare up with my stick movement even at the last second before it touched the ground. The control is there no matter what speed! I think the long center fuse helps keep air supporting the plane at the low speeds.

aaron_gx
5th April 2015, 10:17 AM
Oh and they are 2x 4000mah4s zippy 40c batteries. They are old cells and dont have thier full 8000mah, but 6500mah got me 30 minutes in the air. i have a set of fresh cells on their way From HK.

5th April 2015, 11:25 AM
Nice Aaron flying and keep the vids coming.


Does anyone have pics side by side with a Z3 to compare the size; the fuse looks to be fairly larger than the Z3?

aaron_gx
5th April 2015, 11:49 AM
Scale it up from 47" Z3 to 60" for the Drak. Wish i had a z3 for a side by side picture for you to see.

If it doesn't go then it doesn't go and at least we tried.

If you don't make it the kickstarter amount, are you still intending to release this model somehow?

kross1

If you don't make it the kickstarter amount, are you still intending to release this model somehow?

Chris said previously he will, and is already talking with the local molding company about it. Our cost may increase slightly, wait and see. Chris will let us know once he has the numbers together, so we can place pre-orders on ritewingrc.com, but first has to see how the kickstarter does, and what he can work out with the molder.

If the kickstarter succeeds he won't need this back-out plan, we are fortunate he's willing to still continue, if possible, if the kickstarter falls short.

I unfortunetely had to withdraw from the kickstarter. But have put together a wee plan to let me get a drak a bit further down the track when Chris has them available. Still supporting every which way possible. Just the ks and my timings not aligned at the moment. :)

it was one way,actually 12.9miles total of just under 26 mile round trip. it is a z3, SS motor, ritewing esc(now dead esc, hd a bad landing in the ocean), 2 4s 6000 glacier batteries, 10x6 prop, ruby FC, exhume, and tbs 2.4 Vtx

How long is the build time for the Drak?


On the molded one it takes me 3 days to cut and frame up one, then about 1 week or more to build.
If we do the molded version, you could most likely build it complete in a few days dep on how crazy you get.

johansson939
15th April 2015, 10:18 PM
So the preordered Draks takes some time to get in the air?
There is no intention to make them as Rvjet. That one seems very fast to build and easy too.

ritewing
15th April 2015, 10:24 PM
Yes the pre-order Draks will be the molded EPP version they will build fast . I will not kit and sell the Hotwire cut version. The time alone to do it makes that option completely unfeasible .

ritewing
17th April 2015, 12:01 AM
Yes the base kit is 265.00 , the parts and film would be just like the Z3 parts for rods film and motor esc , ect .
My cost on this project is 85k with mold and first minimum order of foam parts . I have already forked some cash over to get some paid on the mold. The Foam is premium, the mold is German and plane designed by me. Its not Cheap to go this route, but that's what makes it something you just cant get elsewhere.

Drak 60 Base kit is 265.00, that's EPP wings ,fuse all carbon with FG sleeves and glass spars with all coroplast ,verts winglets and CNC motor mount assemblies

Control rods are 20.00
Lam Film is 35.00
SS motor and 85 amp esc combo is 140.00
Mobius Flight cam tough box 25.00, same a Z3 that's on my website.

If you have any questions let me know if you need something other than what's listed.

Hey Chris,

while you are looking for people who are willing to preorder the Drak, I would suggest to update the Kickstarter page with some info about the plan B too (there are some questions (https://www.kickstarter.com/projects/1598250936/ritewing-drak-the-next-generation-rc-aircraft-dron/comments) about it there).

In the meantime, I am still waiting for the small version of the Drak :-))

I'm looking to start playing with ECalc for motor and prop combinations. Looking for something biased to slow, sustained and steady, on 4s - probably 5000 to 10k mAH of juice.

What is the rough weight of the Drak airframe? I like to size with Watts per kilo.

What is the rough cruising speed? She seems to have a very wide speed range.

A Drak power plant discussion may deserve it's own thread...

Question . Trying to figure out whether the Drak is going to be able to do what i want . i.e camera wise . Looking using the DRAK for crop scouting using a hyper spectrum or multi spectrum camera . The most common dimensions are 4.8 in x 2.6 in x 1.8 in or 4.5 in. x 3.0 in. x 2.38 in . Will it work or not ?

kross1
19th May 2015, 12:40 PM
I am not "the authority", but I think it will all depend upon what size is what dimension, and weight. As long as you can get the camera mounted to the airframe, while maintaining the proper center of gravity, and protect the camera appropriately.... it should work.

Is that possible, depends.

ritewing
19th May 2015, 12:50 PM
On the center of gravity it is just over four and three quarters wide right to left forward and back is not an issue, the death is around 3 inches deep before you even cut the hole for the lens. I will see if I can get the final dimensions for you today, but we can fit an NEX 5 in it no problem

Can you tell us more about the canards ck?
Will they be cut out of coro like the winglets typically are, or are they gonna be molded foam too? You mentioned on facebook that they are not passive... Will we have to have a separate servo to work it then?

Honestly, these latest renders are jaw dropping. it's going to be a crime to FPV something that looks this good.. I"m afraid I'll be LOSing it half the time.... with a bib on to soak up my drool.

ritewing
11th June 2015, 11:32 PM
The cannards will be EPP molded, they can be single servo, or dual. I don't see the need for dual servos though. We want mix in a little elevator mostly.
The Drak was designed for major utility use with extreme performance from fast to slow.

If you want to map or rip canyons and mountains that are far away , that what this is for.
Its also good for spot landing with heavy gear, and ripping across the field at 100 mph at 1 foot off the deck.
To top it off it will also be extremely durable .

Canards!!! Thats so cool. So, I can imagine what the canards are going to do to the flight characteristics, but what was the real reason for adding them? Better linear flight stability? Extra authority? I just cant imagine this plane flying better than it already does!

ritewing
12th June 2015, 02:08 PM
The Canards will add even more stability, it makes the foil have even better anti stall manners, it will keep the center of the foil live.
Its possible if tuned properly you could make it capable of low speed cobra style high AOA power on landing in tight areas.

We are always landing in crazy areas so why not, this is not new it was apart of my plan since the get go. Yes why not vent it where I can in the mold. If you don't want the vent cover it with lam.

The mix valleys at the TE are for reducing prop slap across the void, this will mix the TE airflow better make less noise and more efficient . I did this on the TBS Capachinga when we drew it, they were more if a thinned TE Valley though, I di not want to modify it that thin on the Drak.

This is looking absolutely amazing. So glad I pre-ordered it too. I only wish i didn't have to lose most of the Summer waiting for it! I didn't expect the canards to actually be functional. I'm a little afraid they might be "grass-catchers" on the first landing, so we'll have to figure out how to raise and protect them. Bottom fin in the nose to land on? This thing is going to be a real b to laminate! :)

You are absolutely correct... if sparred properly (which Chris is very experienced in designing this in). The lamination however will add a considerable amount of durability (hangar rash), stiffness, and also reduced drag. It all depends on how and where you fly. That is the best part about this hobby... there isn't just one solution, rather the solution that gets you the results that you want/need.

Those channels come in quite handy for routing wires, if you are building for max range. On my Z3, I mounted the dragonlink RX in one of the saddle bays, and routed the antenna coax down the channel to the wingtip. On the other wingtip, I mounted my video TX, and routed a braided wire from it through the channel to the VTX connection in the other saddle bay. Makes for a very clean install, with very good component separation.

Hi Yes we have too used the channels like this. But I find I don't need more than a few inches of separation to get long range without adding thing out in the wings.

Chris, I believe you've been flying your test Drak with a Pixhawk. Do you see a way to incorporate a variable AOA canard with a Pixhawk?

ritewing
18th June 2015, 01:56 AM
I have a few ideas that we will be testing, it would be awesome to do a flaperon setup and have them be elevator, and then flaperon mixed when you want to stop it in the air under power, this would allow no stall powered on slow landings, then you can do a standard elevon mix to them so they only get input from elevator only.
This way you do a 10 to 20 percent mix and this makes it crazy agile.

In FBW and other pixhawk modes we can tune a few ways , we will mess with it to get some nice parameters for you guys, plus we hope others will share with us what they find they like.

Cant wait to get this molded one in my hands.

Hey Chris,
If I were to not spray on some plastidip and cover the silver EPP with 5mil lam is it advised to spray M77 on the EPP prior to covering? I've never laminated EPP in the past without first covering the EPP with 3M strapping tape and then covered with Ultracote followed by lam.

route81
18th June 2015, 10:28 AM
No engineer but I do fly the real stuff and was once involved with the development of this:
63453

She was actually a three lift surface acft but believe me, getting all the canard-wing-elevator in tune had been a crazy task, and we had a rudder.

Not having a rudder, the Drak60 has no control on it's longitudinal axis. On this axis all it has is airflow induced stability (courtesy of the verticals, the saddles) but no control.
If on high AOA attitude, the nose starts to tip sideways there is no way to force it back in.
So, thinking of the "COBRA" high AOA flight mode, IMO the real minima will be also limited by how much air flows on the verts.
Recovery maneuver would be to throttle up, push nose down, and level out taking also torque into consideration.

YES YES!! This IS going to be fun!

OK, noob laminating question here.... Done lots of monokote on balsa/ply in the past however.....

Is the process basically as follows?

1) build/prepare the plane, filler as needed, light sanding
2) Spray M77 or equivalent to get paint to adhere better to EPP?
3) Paint, krylon or rustoleum spray most likely
4) Clear laminate, applied like it were monokote, ironed on

Optionally per previous post, use monokote instead of paint, and laminate over it for added strength?

Optionally, no need for paint/laminate at all.... I do plan on laminating it though for the experience, and added durability.

Optionally, spray PlastiDip or equivalent into the equipment bays. Some are discussing doing the whole plane.... have to see that.

Rustoleum Ultra Cover 2x works very well on EPP.
I've never used 3M Super 77, only needed if your laminate doesn't have enough adhesive already. The stuff from canuck engineering is great without 77.
Laminate needs higher temperatures and more heat than monokote but yes apply it the same way.

I'll be putting sticky-back trim style monokote over the laminate on a plane I'm working on.

Plasti dip and paint can get heavier than you think, but for a plane like the Drak it probably won't care.

You can clear lam and then iron Monokote over that for design wherever you want. Thatīs how I do all my rigs.
Never used any additional adhesive on EPP. Just good lam.

Route81, are you saying the canards will be a detriment?

NO.
Based on what I see and hear in the videos made both by CK and StoneBlue Av., I think the Drak is an acft one can fly in different setups.
People who have flown it for the first time seem to think they have flown it for ages, so stable and predictable it is.

IMO, you can go "plain vanilla" (if we can can say this of this beautiful aerodyne) or start adding some chili pepper (jalapeno vulgaris) by adding fixed canards and then up to real Carolina Reaper (google this if unknown...) with variable canards working with flaperons and throttle.
So, unless the longer nose on the production kits make the use of canards mandatory (Chris correct me if wrong) you can go like:

Stage 1: Clean, no frills, no canard
Stage 2: Add fixed canards for more lift on the front at slow, moderate AOA flight attitudes
Stage 3: Canards can be moved by servo, you open more of the flight envelope by having more options of AOA/speed
Stage 4: left and right canards move indipendently....this is going into insane...

Always remember with this kind of configuration: you want the canard surfaces to stall first.

Route you are pretty Rite on, the nice thing is the Drak design by nature will work very well with canards, and it already rocks without.
All we need now is vectored thrust!

I am not saying the Drak will fly like this, but these canards show some real fun capabilities on these jets.

I'm thinking that FPV utility maxes out at stage 2, but suddenly the LOS possibilities are really interesting beyond that!

Hmm. It may be worth considering split elevons or even duckerons for yaw authority. This functionality was broken in APM Plane (or whatever they call it for Pixhawk, now). But, I believe it has been fixed in the latest revision. This would require two servos per wing (plus the canards). Just a thought.

ritewing
19th June 2015, 12:09 PM
My Main goal with the canards is for landing, you can use it like you say as duckeron or flapperon and bring it in for a tight LZ.
Or use FBW and put the canard on a dial or switch and let the autopilot do the stabilization.
In A UAV mapping plane this is a huge plus. Most landing Zones are questionable , this is when the aircraft take the most abuse.

I am sure a few of you mad scientist will get some params dialed.
We will also be working on a few setups.

I wouldn't fly a plane like the drak on batteries rated at only 10c.


Sorry Hemerly I did not mean to Edit this post, only to quote it with my response, I hit the wrong button

ritewing
19th June 2015, 11:25 PM
Experience from all my testing I am sure 3s would be way inefficient, 4s is ok, 5s is very powerful and really efficient , 6s is very powerful and very efficient, I will soon determine if the weight of the extra cell is measurably more efficient than the 5s .
All of these cell counts are using this 11/7, but the motors are all differing kv ranges.


if you run 3s your amp draw would be sky high compared to the 5s, I would not run it on 3s ever on this big Drak!
I have been running a 5s 8400 and its very efficient and powerful. I have had it up on 5s for 55 mins and it only used 7200 of the 8400.
It could have done over an hr easy.

I wouldn't fly a plane like the drak on batteries rated at only 10c. [QUOTE=Hmerly;707055] If that's a true 10 c at 10 amp hr that's 100 amps capable and they should be fine.
But that's the question, are they 10 c ?? With that being said I have never seen real true c rating ON HK cells.

LVSloper
20th June 2015, 01:31 AM
I guess maybe I should buy a couple of the HK 10c lipos and give them a try in the Z3. The Z3 pulls about 60A on launch and cruises around 10-14A for the most part. If the batteries don't work out; I can always use them in my Skyhunter for long range flights. What kind of amps does the Drak pull on launch and vertical climbs?

aaron_gx
20th June 2015, 11:18 AM
on 4s, I pull +/- 85A on take off. 11x7 with ritewing esc and motor combo. I am at 900m altitude, if that makes much difference.

Once in the air, WOT is only 65-70A. (only lol)

Hay Chris ..

Is the SS motor and ESC ok with 11x7 .. running a 10x7 now but going up to a 11 would give me lower cruse amps and longer flights ..

Just wanted to check that a ruby launch would be ok with a 11x7 amp pull

This is on my Z3


cheers


Keep up the good working and mmm looking forward to the motor set up you sort out

A multitude? Isn't there only a few hand cut Draks out there? So far I'm reading things like "I cannot recall what he called it for numbers, but it is same physical size as a Turnigy 3542..." And that motor is rated at 4S so if one plans to run 5 or 6S you're still looking for a motor.

Yes. There are three on FPVLAB including my own. Not to mention its good to know how to choose a motor on your own.

I suggest 5s on a 3515 cobra & 11x7

22nd June 2015, 05:36 PM
The One Aaron GX runs may not be my motor of choice, I am going more power and efficiency, the last few weeks of testing has shown some great results in a whole new motor size and weight. I have found mind blowing combo for the Drak on 5s, it stays cool and it gives more performance at 1/2 the amp draw than the 2820 1200 kv that Agx has. So it sips like the Z3 2815 ss 1300 combo, but its a 60 inch wing so we can use that tiny motor, and the Drak loves 5s more than 4s.
Don't be confused, I have not nailed it down yet completely, I am in talks with the motor MFG now, the new size is a 3515 size.

Its all about the Testing and tweaking.

My battery MFG just now came out with an 8400 at about the same weight, I am looking at getting them here soon.
The batteries don't need to be this big, we can get more spec as we get closer.

solo, i'm a huge baby when it comes to props, I've had my pinky tip sewn back on.

I launch similar to this, but
-right wing in right hand
-i stand backwards to where i'm throwing
-throw it at like 70 degrees with full throttle
-i'm also using a elevator mix to add a bunch of up.

I'll try to get a video next time i fly.

1st July 2015, 02:21 AM
No worries ,anyone who ordered will get the best most eff setup I come up with, it will be from a ton of my testing.
It will rip and then sip, just like the SS series.

I just went up to the 35 size now, so your getting a larger motor than originally specked.
It is more power and less amps and runs cooler than the first motors we were using. This comes with a lot of test between voltage Kv And size motors and props. I have about 50 motors I have tested on these so far.

And wow I just found a few Gems in the last few weeks when it comes to sweet spots
