I had the same combo on my UCD. When it got hot out I did not have enough power to hold a hover. Then I switch to a OS .91 FX (apc 15x6) and removed the baffle from the muffler and it had great power.
Just fly it the way it comes out of the box for now. Set your CD back between 5-6 inches for your prefrence. Just fly it the way it is. Then one day when you make a nice smooth landing and the landing gear just falls off. Don't worry it isn't your fault( they aren't put in very well). There isn't much inside for the landing gear to hold onto so it needs a little extra reinforcement. (Just be careful not to add too much weight)
Good luck

Hey guys,
I just inherited a .60 size u can do and I ordered a .91 os surpass II and a 16 x 4 prop, I was just wondering what kind of hovering capabilities I should be looking for and for any sugestions.
