I had the CMP Chipmunk and put a Saito 56 in it. It flew excellent and tracked wonderfully. I got really stupid one day and tried to hover it. It did,.......then it didn't! The plane was real strong and just cracked the fuse in front of the wing. It would have been an easy fix, but I gave it to a buddy that really wanted it. Minus my Saito of course!!! I liked it well enough that I would buy another! The build quality on the one I had was very good and the hardware is the exact same stuff that World Models uses.
