What props are you running now? What RPM & speed? With the motors you have & 1.5 gears, I would not think that you need any bigger props than 32 or 34's. As stated above only need to go to 1.36 gear ratio is when you can not get a prop that is big enough. You can now buy props up to 36". Why is your builder telling you this?

The props at 34" and over are not as efficient and they suck getting on plane.

I'm told that a (numerically) higher drive ratio and a taller prop will accelerate faster than a lower drive ratio and smaller prop. Why that is, I don't know.
