I am writing this in hope someone has an answer. I have a Nitro model Bobcat which is electrified. A friend had one with glow and it went in. It went the entire length of our field and went straight vertical and was uncontrollable. Has anyone experienced this and do you have an answer to the cause? We feel the problem might be the CG but can't get a definite answer from Nitro. No one there seems to have any technical answers. The mains were too far back and they were moved forward closer to the approximate CG. Also the horizontal stab was changed out to a flat stab since an aeronautical engineer in our club felt a lifting stab would keep the nose from rotation.
I was told by John of Nitro that a user of username OPJOSE is an expert on this plane. Hopefully I will get a response from same. E-mail me at [email protected]

Thank you RCPULLER
