How about flight characteristics of the ucd 46? Mine has a Saito 100 on it, at 5000 feet, turning a 16x4 apc at 9300. It is my second ucd, oops. I ran flaperons on the old one, and spoilerons on the current model. With spoilerons it will waterfall like mad but falls to the side, probably because the motor is sideways and I didn't lateral balance the plane. Elevators wing rock like crazy with spoilerons on. I could get the old plane with an mvvs 77 to do inverted climbing flat spins out of a waterfall, but haven't been able to on the new one. I haven't done much harriering with the spoilerons, without it wing rocks. Knife edge takes a lot of aileron to hold, just a touch of elevator when inverted flying.
Blenders start out well then slow into a floppy spin.
My cg is a hair over 6 inches, the plane weights 6 lbs 2 oz.

This is all at the hands of a rookie pilot, maybe with more stick time I can get the wing rock tuned out.

Think I should lateral balance it?
