RE: prop diameter vs pitch
It would seem to me that given all the information here the novice would be better off going with a larger diameter/lower pitch prop because the take off would be faster, the glide would be slower, and the over all flying speed would be slower, three things that would seem to me to be in the novices favor. I am flying a Superstar 40 with an OS 46AX engine and have an 11x7 prop and it seems to do well. People say that I might be better with an 11x6 prop, but I try to find those props at the hobby stores and they are always sold out. It must be a very popular prop.
