prop selection will be very dependant on model, fuel, and other factors. How the model will be flown and how the model responds to the prop are big big factors in choosing the best prop for the application. You just have to try some and see what you like.

On the 110 find a prop that turns about 9400 rpm and fly it there. There will be more than one choice that fits the bill. I know that APC 15-10 on CP 30% heli fuel is a good choice. I also know that the APC 14-12 is a pretty good choice also.

Less nitro mean you need to use less prop. More Nitro will allow you to run larger loads for props.

What ever you do run it at about 9400rpm and the engine will make the ebst power and be the happiest.
