I own and fly a bunch of RC planes but most of my experience has been powered gliders (eclipse, calypso, aspire, cularis) and electric flying wings (Combat Wings). I own and fly a few nitro planes but they are all high wing "trainers' except for a SkyLark Jr. that is underpowered and needs something more than an stock 049 Cox. I have destroyed a couple as well that I am not counting. This Devil Plane is the touchiest darn thing I have tried to fly and I have to say it's humbling, downright scary at times. Regarding the motor, I have found that if I set it rich it will respond to partial throttle (sometimes it works better on partial than full) and as the tank empties it leans out. I had a heck of a time getting the motor to start until I got rid of the integral tank which would siphon into the engine laying on its side, and installed a larger tank positioned a tad below the spray bar orifice.
