Scalecraft,
I believe it's unfortunate we have to choose sides. However, flying with a 4 blade prop without a reduction drive is possible as has been stated by Kilroy52. There are too many EXPERTS in any hobby who claim to know it all, but are afraid to face new challenges and make change in what is all ready ingrained in their fortitude. I was scared to death of computer radios when they first appeared. Now I have one and get tickled when I learn a new feature that helps my airplane fly better, (I still have a few non-computer radios I use regularly). How about trying Kilroy52's method and see what happens? I'm going to try it and see what I can determine for my own benefit. One small step for a modeler, One Giant Leap for Model Aviation!

"Keep 'Em Flying!"
