Large Model Association Forum

hi all,

i have just aquired a Zenoah Kalt 22cc engine which is in quite good nick. it came with a less than perfect 16x10 so i replaced with a serviceable prop of the same size, and ran it up. my question is: what is the best size prop for this engine. i suspect it has come from a helicopter and is destined for a trainer type model.

thanks in advance

Been running my one on a 16x8 APC. Seams happy with that.
