Tested in my office. It needed these adjustments out of the box before it would fly right. Gears were jammed together - adjusted mesh; drifted right despite full left trim - adjusted servo linkage; had almost no cyclic movement, so no control - adjusted servo "extent" on 4in1 from minimum to maximum.
It flies OK, but it slides a lot in the corners and banking hard makes it lose a lot of altitude. High speed turns will require a lot of room so I'll have to test it outside to see what kind of speed I can get out of it.
The stability is good, but you sacrifice agility. It may be slightly more stable than an Esky HoneyBee FP V2 for flying indoors, and it is a little smaller, but it won't zip around like a HoneyBee and it is more fragile. Mechaincally it seems well made and the finish is very good. A consistant altitude was hard to hold when flying around (especially in turns) and it seems underpowered.
