I'm installing an OS20FP in an Old Time plane, and I just discovered that my NIB 20 has an iron piston.

The plane is a bit nose-heavy and I need the lightest (also the best performing) setup I can get.

Does anyone know if the iron-piston version is heavier than the ABC? Also how they compare for performance and vibration?

Thanks,
Kim Mortimore

The iron version is lighter. Weight New engines, without muffler, with RC carb Iron = 198 g Alum = 201 g

Brucester,

You signed up with Stunt Hanger just to answer my FP 20 question? What a friend! Gilroy boyz rock 'n roll (and fly Ringmasters too)!

Thanks buddy,
