saito 100GK. I have seen many u-can-do's, my boy had a ys 120 in one, too much weight. a freind of mine has a YS 110 in one, not a bad choice. couple others have 100's in em. 2-strokes not bad in them, but of all the 3d things I have flown, I prefer the saito's. and the 100 is a hoss- and light.

by the way, been flying since 76, I am not a parrot but speak from experience! currently flying this, with saito 72 g.k.; sig profile ultimate, scratch built fuse, 4 lbs. and does the STUFF! got a 100 for x-mas, building a giles for it ( currently in a razzle with NO rudder authority in hover) so, ask around- but the 100GK is it!
