Ran into another little snag with my UCD...no blind nuts in the firewall to mount the motor...only 4 of the 8 bolts were even long enough to go thru the engine mount so off to the LHS for some hardware...I decided not to spend anothe 300.00 on this plane for a motor so I'm putting my ST90 on it and see how it flys (before cutting the cowl of course) then if it dont cut it I'll pop for a YS91 or Saito 100. everything else about the plane looks pretty good. I must have gotton a newbie builder that built my wing. Ann Marie says an OS91fx or 91 four stroke flys the plane well. The OS91fx is supposed to have slighty more power than the 90ST but it weighs about 4 oz. more also...we'll see.
