Cloud Dancer...... Dances!!!
The plane is VERY light, for an experienced flier the .53 woudl be ideal for 3D, for my self is a little too much I'm thinking abour putting a 46 myself, but the 53 is the only engine I have right now.
Having said that, the 53 does not induce adverse flying characteristics in the plane, it flies nice and stable at 1/3 throttle at 3/4 throttle it goes very fast, approach on final is steady.
So If you can do advanced maneuvers.. keep the .53 with reduced throw on aierons for the first flight.
