GP Ultimate Biplane
 

With a YS 120, it is capable of ANYTHING. Several club members have one, and they all fly them with either an OS 120, or a YS 120. The ones with the YS engines will accelerate rapidly out of a hover. They all land pretty slow for a bipe too. Just remember that the plane has more drag than single winged planes, so if your engine quits it will slow down FAST. Just make sure to build it light, and build it strong.

YS120 ???? !!! ... i think thats too much !!! ...

The Great Planes Ultimate Bipe its a .40 size biplane ... in fact, with a good tuned OS .46FX + tuned pipe it will do almost anything ... ! ...

We have a couple of guys at the club with that plane, and with a MVVS .49 + minipipe it does all ...

hope this help ...

My friend had a Saito 72 on his and loved it dearly. It weiged a good 6 or 7 pounds but was a great aerobatic plane.

He could do the prettiest inverted flat spins with it. It could knife edge, hover, anything you wanted it could do with a little practice. I had a chance to fly it a few times and noticed the rudder has great athority and the elevator had to be tuned down because it was very very affective.

His wing on top almost came off once because the bolts sheared completely off, so he replaced them and hasnt had a problem since. Good luck with yours

It turns out that the guys plane I was talking about, was a Goldberg with a Great Planes sticker on it. Oh well! My mistake!
