http://stunthanger.com/smf/index.php?topic=877.0this one is just the rest of the story,,
http://stunthanger.com/smf/index.php?topic=878.0as for personally, the Ukey, I have one with the big wing,, I fly it with an LA .25 and an APC 10x4 prop. GMA powermaster fuel, somewhere around 54 foot lines and the motor just this side of leaned out so a slightly fat 2 stroke. Plane flies as honest as about anything I have. Squares are a bit tough less "precision" than with a full blown stunter but definetly doable.
for an example of repairability, at a contest last year, I lost my primary plane, in the process of trying to get ready to fly the ukey, I managed to stuff it, breaking the wing clear off the outboard side, some 5 min epoxy and a hald hour in the sun I was back flying again. Then I promptly stuffed it AGAIN, this time the inboard wingsuffered damage. It to was repaired and able to make my competition flights later the same day. (yeah well I dont crash quite so much now, that was my second contest and I was a bit rattled you know?) Its a good one, and will bring you along painlessly.
