RE: noise reduction
you will kill the power with large prop and three blades are worse.
I have a new 23" (actually it is more like 22.5") from RCShowcase which is quiet and pulls very well -it is the 23x12 ZM -the pitch is a fooler - it revs about same as the Mejzlic 22x10 but very quiet -no rip - look at the tips in their picture of it..
