Aerobatic Tiger - My second scratch build foamie


First one was Zagi-type flying wing.
This one is all (fuse and wings) white EPS, covered with 3/4 oz fiberglass and WBPU
carbon tube as a wing spar, tail is made of strudy board and ailerons are 3/16 balsa
4 HS-55 microservos, Hitec 555 Rx, homemade ESC

WS: 775mm / 30.5in
AUW: 502g / 17.8oz
GWS EPS-300C-BS (4.33)
prop GWS 9.0"x7.0"
8 cells, 600AR

It flies, but it is underpowered/overweight, flew it couple of dozen times, first flights were disaster (my mistake, tried to fly it in windy weather). In calm conditions you can fly it slowly in small place, it would make nice park flier.
I'll fly it for while and when fuse breaks again I will redo it and maybe put Speed400 direct drive just to see difference

Hi Roman.
Are you sure your're going to be able to see that model in Flight?
Well I saw the first flight and I told you then that I thought it would fly well.
Now, your plane made me crave Frosted Flakes.
Call your plane Tony the Tiger.

Hi Rob

the reason why it was draging to the left was torque from the prop. I set a bit of right thrust on the engine mount and it helped a lot. However it needs a bit more because I still have to compensate with ailerons.

I have made that morning on local park and it actualy TOG (there was landing gear on the plane at that time) and there was almost no wind.
