I own both models of the UCD. I run a Saito .65 on the .46 size and it flys well. I want a little more power for hovering so I was thinking about using a tower .75 I have laying around on it with a 14X4 prop. If not I also have a .60 size with no motor in it and want to get it in the air too. Will that motor and prop combo hover it at all? Has anyone seen either of these combos flown? Please help...
