Flew my UCD yesterday and today even with the broken ribs...I have a ST90 (G90) with 14x6 MA prop. Thhe motor flew my US60 better, probably cause its lighter,, about 1/2 lb...US60=6 1//4 lbs
UCD without pants or cowl 6 1/2 lbs...now i must admit the st90 was not running as good ...slow transition...not the revs but it didnt quit so I flew it anyway...

This plane flys great...I was doing knife edge loops real tite...I'll try larger ones but will have to program in a lot of up ele cause at the speed I need to do large loops it pitches towards the wheel bad...lots of rudder...can go very slow knife edge right in to a hover and torke roll...I do have to move back the cg and try it some more...couldnt quite get a waterfall going...it was easier without spoilerons on. Does the sweetest inverted elevators...into the wind it just sat there and didnt even decend..upright harriers wanted to wingrock and roll out but I think that will improve alot by moveing the cg back. his plane is even easy for me to hover and I'm just getting into the 3D stuff. Some more experimenting with mixes and getting my motor to run better will tell the whole story...I would like to hear about others...truthfully I dont think a Saito 1.20 or at least a YS91 fz would be too much motor for this plane. when I add the cowl and pants I'll be about 7 lbs as advertised...imagine that, the advertised weight!! I had a few problems with mine , like broken ribs and no blind nuts for the engine mount but I expected this with the first batch off the assembly line. At least it makes up for it a little by the way it flys...get one, you'll see...also the Kyosho
Flip looks interesting but of course it cost more cause it says Kyosho. 8^)
