I have just got a new scale corsair and i thought it would look good with a 3 blade prop than a two.
My question is whats the difference, good and bad.
and what make is better i use MAS.

If your corsair is a large scale plane with a large slow engine a multi bladed prop will work fine. Most two stroke glow engines run at too high of RPM for anything more than a two bladed prop to be efficient.

With the two cycle engine the following blade is in the air stream of the leading blade and therefor has less air to move, I would suggest that you us a static four bladed prop for scale and a two bladed prop for flying with a two cycle engine.

Cost!!! I break alot of props i wouldn't want to keep changes a four bladed prop. It doesn't really add power its basically just for looks (Got to admit they do look good) and a good waste of money. (Theres way better things to buy.)

Just my view point,
