I am almost sure that what I have is an old pylon racing engine, HP 40R, as the one here http://www.mh-aerotools.de/airfoils...#F3DEngineHP40P, however, when I looked at the piston, it's much different than the HP40R-PR on the website.
Does anyone know what engine I really have?
Any info on it, like power rating, fuel type and such?
Thanks.
