Much better results after the second try at making a canopy. Didn't change anything about the mold yet, so still lots of distortion, but for the prototype this canopy should do alright.

That looks really slick. So what was the process this time versus the last one?

Forced the mold + brace further through the narrowing of the bottle and added more bracing on the rear so that the bottle would have less room to shrink before actually wrapping itself around the mold.
Now I need to make sure the wood grain doesn't imprint itself into the next canopy and I might also sand a certain area flat to integrate a window for the camera to look through. But in that case it would probably be a good idea to have 1 canopy purely for looks with some interior and pilots' heads inside and one that can accept the camera through a slot in the black-painted base. For the former the canopy wouldn't even have to pe perfect and for the latter it's gonna look alot different anyway.

To make clear what I mean:

@DualDesertEagle from my maiden experience and 15 sec of flight, i did single edf version with the air directed straight over elevators and mine flew just straight and it would not nose up, did not have elevator authority at all, even at full throws, i think those elevators are just too small for the size of the bird. Later i went and saw the dominator videos and you can clearly see when he flies it straight and pulls back on the stick for plane to go vertical straight you can see the elevons are mixed with the ailerons, meaning you pull stick back both elevators are up and also both Ailerons move along, i think for your maiden flight at least you should do this. Mine was perfectly balanced on cg as it was not diving at all, it just flew straight and refused to go up.

Yes, that's how it was intended from the very beginning, how I planned it from the beginning and how I'm currently setting it up. I was never planning to use the outer elevons as ailerons only.

Hey guys, it's been more than half a year since I posted here but after some problems and more than 5 months of working in another country I finally made some good progress on the model again, and believe it or not, but the plane has already survived its first test flight, exactly as seen on the picture! I had to wedge the battery inbetween the walls of the nose section to have it sit somewhat secure for the flight and it turned out that even so the CG was just BARELY in a flyable position. The plane was quite tailheavy and didn't like going forward all that much yet, and I really hope I won't have to add any unecessary weight to the nose with the model finished. On top of that it ain't all that pretty with all those hot glue seams but luckily this is just the prototype. the final model will be made out of 3 mm depron and with some other type of glue, so I'm guessing it's gonna be somewhere between a quarter and a third lighter than this thing here. But for now I'm looking forward to get this done and flying properly to finally have some REAL fun again.

P.S. I forgot to mention that I also did some hand held testing of the thrust vectoring and while the roll wasn't that strong the pitch and yaw were pretty powerful! Can't wait to test it in flight once the plane is dialed in properly!

Looking at the design I would expect pretty poor performance with so much material in front and behind the prop.
I would also expect pretty vague handling characteristics, like drifting around in the wind and very susceptible to flipping in side winds. I think it will enjoy flying in hi-alpha though.
Best of luck with the next flight.
Wot, no Depron?

There's not THAT much stuff in front of and behind the prop actually. It's mounted to the rear of the center fuselage just like on most of the RCP jets. Behind it there's a center wall with the rudder servo in it and of course the 2 thrust vecoring rudders. The bottom and top plate shouldn't be more of an obstruction as on any RCP plane.


And I have just finished the prototype! And with the plane being just that there's the HUGE advantage of it not having to do anything else than fly, allowing quick and dirty solutions all day long instead of having to sit through making everything nice and shiny. One of those solutions is the one I devised for the hatch lock, which is basically just a stick poked across the fuselage and a piece of depron glued to the bottom of the hatch.

I'm no more than 5 minutes away from tossing this thing up into the air again and seeing how it flies with the CG being about an inch and a half aft of the score where the air intakes end.



Ok, so I just did the test flight and I AM SPEECHLESS!



This thing, despite being slapped together as I'd done it in 5 minutes, flies INCREDIBLY STABLE and is HYPER FUN TO FLY!

I did notice that it's a tad nose heavy now tho, and it doesn't like bank & yank so much, needs just a little bit of rudder to fly clean turns, but other than that I've never loved to fly a plane that much!

Gonna try and film the next flight with my helmet cam so u can all see it fly!

Turns out I was a little too quick with my positive judgement of the plane. I did try and film a good flight but in the windy conditions the plane more or less did whatever it wanted, especially when I pulled up on the nose for some high-alpha, that's when I completely lost all control and the plane spontaneously decided to do a full roll and splash into the drink. I just barely managed to have it land flat on its belly at that and ran to pull it out of the water as fast as I could. Then I checked if any of the electronics got wet but hey all looked fine so I gave it another go. After a few hundred feet of more or less straight flying it did another spontaneous roll and a nose dive into the field. When I checked the control surfaces I noticed the right thrust vectoring rudder wasn't responding, but everything else was working fine, so I guessed that a wind gust or so was to blame for the crash.

But then again, I was already warned by Nakul that another guy who had built this plane the same way didn't get it to fly properly. I'd have to disagree when it comes to level flying without any stunts in no-wind conditions but experiencing what I just did I'll have to say he was right.

So I guess it's time to get all the electronics out and put everything aside for a few days to have any possible moisture dry off and then move on to something else. Probably wouldn't be a bad idea to build another F-18, given how well that thing flew, but I have yet to try out the MiG-29 V1 that I now have the plans for.

I don't think uploading the plans for this will be necessary anymore, this plane is better off being built as designed by Sergey Alexandrov.

That`s a shame.
You won`t go wrong with the Mig 29 V1 though.

I guessed so

Probably even gonna make 2 of 'em, 1 for me and 1 for my newly found friend. Lacking 2 identical radio and power setups his is gonna be a little less powerful tho, but I don't know how good of a pilot he is anyway, so for starters a little less power might actually suit him better.
