I have acquired a RV-3 if anyone remembers it the tail number is N40DC. The plane as about 282 hrs on it but have not flown in about 10 years. I have inspected the operation of the engine and first major problem is upper left engine mount is moving and the firewall is cracked. I am in the process of removing and replacing but would love more input on this project. I have little build experience But quit mechanical. I am located in Sebastian Florida and would love some input. My number is (860) 857-5249.
