Ok Guys,

I have one of these "bobcat 52" as well and I have converted mine to electric and will first flight this Sunday. One thought I had when I opened the kit was about the rear horizontal stabilizer cross section. My past experiences (not too much of it) in building tells me that it should either be symmetrical or the the airfoil shape should be reversed. As the plane speeds up the lift on the tail increases and will cause the nose to point down ?? Last Sunday one was test flown and the plane did not want to ROG and once full up was applied it literally leaped into the air !! This was with the factory stated C of G (wrong CG). It also proved unstable pitch wise in flight as it keeps nodding its head(probably pilot input to keep the nose up). Too bad this is only a second hand account and I wish I was there to talk to the pilot personally. I have since built a flat plate rear stab that is exchangable as an alternative. Any ideas/input on my observations ??
