Overkill - my new PBF

Heres the start of my new Pizza Box Flyer.

Dubbed 'Overkill" as it is way over built, ally U channel backbone, ally angle for motor mount (700 watts), and 1" flat bar for landing gear, will slim it down a bit with some drill holes.

Rudder is balanced (50% over/under wing) so should rudder turn better than my first PBF !

I have a very similar fuselage for my Slow Stick now. My large outrunner (70a) tore the SS CF fuse to bits when given full throttle. Unfortunately I'll likely have to sell the motor or something because I'm not buying any more planes due to time constraints, and 70amps is just too big for a Slow Stick unless if I can find a suitable 58" SS wing or something (which I haven't, and I don't have the time to assemble my own).

It is, I'm likely going to sell the motor given I don't have any applications for it, and given it's too big for a standard SS wing.

Doh!

Second Flight, 0.8 sec after takeoff

Too fast, she pitched up, then pitched down in the blink of an eye.

Re-did the rear vert, has alot more built in "angle of attack" when on the ground and the Vert itself is a fair bit larger, the rudder is 200 high and 100 deep.

One flight today, wind in the 30 km/r range and blustery, so a short flight just to make sure it can , take off was painless, and the landing gear seems to stabilise it in the air, with the blustery conditions it rocked a fair bit from side to side, but didnt have to correct it as it would rock back in place.

Rudder is effective, very happy
