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.

The 15x4 is definately too small for a 150 Saito. I have a YS .91 spinning a 15x6 with no problem. I would say the 17x6 is a better choice for the 150. I have a YS 1.10 which has been compared to the Saito 150 believe it or not. I have seen a video of the 1.10 spinning a 17x6 like it was nothing. I haven't flown my 1.10 yet, but everyone agrees the power is unbelievable and will put a Saito 120 to shame. So again, I would say a 17x6 or 8 should work fine. If the engine will spin a 17x8, then use a 18x6 for 3D. It will fly slower, but give more thrust.
