Foamie Delta Cox 0,8

400 gr
COX 0.8 cc
In fact, the engine quit exactly at the time of launch !
After that one and only one try, I decided to give the delta to the guy who threw it, he turned it into an electric. It fly perfectly well. A video will be posted soon.

Hi, I made this plane some years ago from a plan on the internet. I put a 3000KV inrunner and a 30A ESC in it. 2 cell LiPo and it was really fast, creating a very high noise. Fun to fly !

When I was still in high school (1976), I built a delta wing, pusher engine Cox TD 051, 2 channel Rc plane. It had a foam wing and balsa fuselage and it looked almost exactly like what you built. When I got to try and fly it, I decided to not trust some other idiot to hand launch my plane, so I did it myself. I had built in a small skid under the wing to hold on to to throw the plane but it was difficult to get a good grip with the oil and smooth surface. The net result was a stall and nose dive. The damage was a broken nose in front of the wing. I suspect that it must have been too heavy and the elevons too small to handle a slow launch.
Yikes. History DOES repeat itself!
I never got to repair or try that plane out again. I regret that I never gave it another go. In my mind, I had categorized this plane as a "not such a good idea" or "not a reliable idea" and just left it at that.
You cannot believe how much I was rooting for your Foamie Delta to fly well, only for it to be as unsuccessful as mine was all those 47 years ago! Oh, well. Please tell me you will try it again!

i made mini lazy bee (balsa) with .10 Enya nitro engine and seems the power is not enough, thus converted to brushless 2205 1600kv and the lazy bee is powerful and stable.
brushless motor is lighter then nitro mini engine and also more powerful

Perhaps the plane is lacking the 'reflex' setting for the elevons: a default small up deflection as their zero position. usually about 5° up

How could you get the CG right with the engine all the way in the back? I have built a delta very similar to that one but I had to mont the 0.049 cox at the front otherwise it would have been extremely tail heavy. Did you use any kind of nose weight?
Just wandering, thanks for the help .

I had to put 60 gr of weight in the nose 🤷🏼‍♂️
