I couldn't find an engine forum, so here goes....

I'm just finishing an AK Models 3D Freedom (finally) and have a Saito 150 on the front. I also have an APC 15 x 4W 3D / Fun Fly prop. Is this enough prop for this engine? Horizon's site lists a prop range from 14 x 10N up to a 18 x 6. I'm hoping the Wide designation might put this prop in that range, but I certainly don't want to over rev the engine, although I don't expent to spend much time at full throttle.

Advice appreciated.
