RE: Piston Damage
kinda like brushing your teeth, maintenace is big on these. I flew the 46FX alot, now I fly the AX, alot. First thing I noticed is the rear bearing does not last as long as they did on the 46FX. The front is original, they never wear out.
I keep an eye on my bearings and use a 16-18 dollar 'swiss' replacement with the plastic cage.
That prop better turn smooth as buttter before flight, otherwise it off to the engine hygenist.
Can someone smart tell me why the steel that's RIGHT next to bearing seems to want to rust first? like some kinda dis-simular metals ?
