Problem is I don't have any of the manyfacturer's charts since the engines I mentioned are all older Enya's (with the exception of the .25 which is a newer O.S.). Anyways, I guess the most important question I was getting at is if there are size/pitch differences between the recommended airboat and plane props with the same sized engine that I should watch for. But I see it doen't matter...so I should have any problems trying to find the plane prop size guidelines for my engines.

Thanks
