My father passed on and left me a bunch of R/C airplanes that I would like to use to get back into the hobby that I loved as a teen. One of the planes is a Sig Kadet Sr. that he built years ago, and I want to get it flying again so I can get some skills back before moving on to something a little more challenging. However the problem I'm having is the motor mount that is currently mounted does not fit any of the engines I have on hand that will fly this plane. I want to pull the old mount off, but it looks like it has been epoxied to the firewall and I'm not sure how to remove it without destroying the firewall. The mount looks to be made of aluminum. Any ideas? Thanks for your help.[8D]
