  • O.S Max 35 FP Nitro Rc Plane Engine Vintage

    Hi and welcome! Here you are bidding on a OS MAX FP 35 nitro plane engine. Reasonable clean condition. Really good compression, but I haven’t tried to start it. I can’t see why it shouldn’t run, I’ve no idea about plane engines, so thought I’d leave it to someone who knows about them. All seems to be complete and functional. Bolts are missing to secure the carb on the engine. Having a clear out, check out my other RC items. Any questions please don’t hesitate to get in touch. :)
