Hah, that's seriously cool. Alas I'd need a bigger euro to take advantage of those I think... I might order a couple to play with but I don't think it'd work. I also think during daylight they wouldn't be that visible outside....

So, here's my tow hook to give me bungee capability
first I found a spot that is approximately 60% from nose to CG which is the recommended point for attaching the hook, and then proceeded to attack with a dremel.
I then cut out a piece of plywood to size, and sacrificed a coat hangar to the gods of RC using some clippers. I epoxied this in place and then added two additional side rails, also epoxied in, and you can see a small L bend at the back to stop the pin being yanked out. I also drilled a few small holes to give the glue some extra grip.
I then installed using gorilla glue and taped it in place while the glue foamed up.
Et voila, tow hook!
This area will be glassed over as part of the belly landing reinforcement work, so it'll get a huge strength boost from that. Hopefully with the addition of the glassing it'll prove to be strong enough! I will need around 10kg of force minimum to launch, although of course the hook won't ever see that kind of load since the eurofighter is free to move when the bungee is released so it should only ever have to overcome the inertia of the jet.
Edit - just weighed her and she is indeed getting a bit porky. Weighing in at just over 2,540g currently with everything! I've been toying with a very lightweight glassing all over using lightweight cloth and PU. Apparently it can be done for a penalty of around 100g on a model this size and it would greatly improve both the toughness and the appearance.... Not sure whether to do it or not!
I'm going to go and find out what kind of weight the guys are flying this model with... I suspect the quoted all up flying weight is with a very small battery.

So, the problem with delays is that I get ideas...
My carbon for the wings is finally in my possession, but I've not yet got to work on the main spars.
Today I tried out some light weight glassing using WBPU and lightweight 25gm cloth. I must say I'm impressed by how easy it is, how much it toughens up the foam, and how light too.
I started off with a canard to see how well it worked and how much weight it would add:
First I filled the gaps in the surface with lightweight filler and sanded it back taking off all the paint from the foam. I also took the opportunity to shape the canard a bit better with a nice sharper trailing edge... Then I covered it with a layer of the lightweight cloth and WBPU (almost invisible!)
Then using grey base paint I put on a few layers while sanding it back to get it smooth. Here it is in between coats and sanding so you can compare to the other canard (ignore colour, it's just a primer coat).
And here's the final article, smooth and primed ready for a light final coat of whatever colour I choose in the end.
So how much weight did it add? 2.8g in total! 0.6g of that was the light weight filler, so the glassing itself was only 2.2g for the canard.
It's now completely resistant to the light knocks that dented the foam before, and while it's not as tough as a proper glassing, it is seriously light weight and a big improvement over bare foam.
Inspired by that I moved on to my dashboard.... filled and sanded to tidy it up:
In the process of glassing:
And glassed, now awaiting some base coat/sanding etc.

Seriously dude.........you need a hobby! Heeheehee!
NICE!

LOL.... +1Originally Posted by c5galaxy engineer
I support you 100%. Flying it is going to be fantastic, that you (we) are enjoying so much the build, that it really doesn't matter...
I thought this was a hobby....
lol.
Good news is my FPV black box shipped yesterday, so hopefully it'll arrive before too long and I'll be able to get some video of the cockpit from the camera's point of view.
I cant wait! did you get express shipping?!?!?!
I think while you have the cockpit out you should wire it so the displays turn red when your batterys are low..........just sayin.......you know cause you are looking for things to work on.

AMAZING WORK!!!!
Cant wait to see the video!

No, didn't get express... it costs me more in the first place and always gets hammered for import duty. If I choose the economy method then 90% of the time it gets through without charges.
So, slow work this stuff now...
I have done a little more glassing, now have both canards, nose cone, dash and am close to getting the tail done.... obviously need to paint the dash and finish off the tail, so don't judge too harshly lol.
I also started work on mounting my wing spars... here you can see one cut out with plywood cross braces inserted for a test fit.
I then glued it all in place using gorilla glue, then topped it off with lightweight filler and sanded back to smooth. The spar is very solidly mounted indeed, I hope the tube mount in the plane comes out equally as strong! I will still be doing two per wing just to be safe. The problem is with two, the alignment is the most important bit - if these two spars aren't perfectly aligned with each other then wing insertion/removal will be incredibly difficult... I may have to come up with a simple jig to make sure they do end up aligned.
And because I need to have something else to distract me since this clearly isn't a big enough project, here's what I've been putting together as well! I bought a turnigy talon v2 and have made some custom mounting plates for extra FPV gear to replace my beaten up Scorpion Y650.... plate for an EZUHF 8ch Diversity RX at the back, eLogger will go beneath the plate. On the right OSD Pro on the bottom of the plate and IMRC 5.8Ghz on top, on the left will go GPS. it makes a nice solid little quad actually - I was quite impressed with the build quality... anyway I know it's not really related but there we go...

WOW. It's coming along great...
If you want - I can turn it into a ball of tape and glue for you!
Beautiful work.
