Nice, maybe it needs to make an appearance as well! 😉
Thanks.... I wish he got to the wings already.

It very likely will, as v4 is under repairs I glide tested v1 to find the right cg... I think I'm really close to nailing it!

Can I stick bushwheels on my UAV and enter it?

I figure i can shorten the take off roll by a few feet by not dragging a long 4 foot fuselage on the ground. Put dual 2217s on it and an aluminum spar with 4s and flaps. With a 3:1 thrust to weight ratio it would be insane. But that depends on me not being too lazy to change the motors.

@Hondo76251 does the plane have to be entirely scratch built?
Hondo76251

No particular requirements on the airframe
VTOL is not STOL correct?
Taildragger
Legendary member
yeah good point... just like in the real backcountry VTOL is cheating. I guess it is up to @Hondo76251 though

Yeah, how do we make that distinction? Hmm...
A good bush plane can darn near hang on the prop and float in, and at this scale they can darn sure hover with a good pilot. Pretty sure we safely say no quads or helicopters. Has to have wings, but would a tilt rotor count then?
Nothing in the contest is specifically judging the length of field required, more cargo capacity, durability, endurance, and pilot skill, so with that in mind lets just say it has to have wings and achieve wing lifted (fwd) flight with the payload challenge. The take off and landing would be the same far as i can figure, Tilt rotor is no distinct advantage on that. Take off however you like, fly a pattern, land however you like, taxi and do a 180, repeat 20 times.
So in summary. It has to have wings and it has to use the wings in fwd flight for the payload to count. Hows that sound?

Sounds good to me. I'll enter my design. I need to put wheels and some way to steer, lol.

Sounds good. Now about the payload challenge, has any plane in past challenges actually made 1:1 payload ratio?

@Hondo76251 we should add a fourth point category because people who go for scale looks (like me) would most likely be sacrificing the other three to some degree.

Nothing says it has to have wheels!
If i wasn't so busy feeding cows I'd do with the sea duck this snowy week! 🤣

Haha looks like everyone in the northwest had warm weather as nature’s April fools joke.

Pretty sure @Ketchup beat that both times, my first beaver (modified bushwacker) was nearly 1.75! (I was going for 200%)

The video i got recorded i got 190% in the air but i pancaked the landing gear when i landed lol
Plane weighed 1lb 10oz and lifted 3lb 2 oz of payload

Wow! I gotta be able to turn for the landings some how! I think I am going to de-gyro it and program in differential thrust and slap some bush wheels on it.
