I just picked up the new FMS P47 Razorback. Set it all up at neutral settings to start out / reasonable dual rates. The maiden went really bad. Not sure why but went out of control while trying to trim came nose first to the ground. Not to much bad damage. A little glue and a new prop later and time to try again. Second time up was going ok for a minute, thought I had it trimmed then suddenly it went into a spiral to the ground again. I don't get it,, I have set up other new planes and never had any big trouble. Always got them trimmed and to the ground safely but not this one. Did a range check/ receiver antennae at 90 degrees. Wonder what I am doing wrong with this one.. Puzzled ......Any Ideas ?
