Prop Cupping

[impba3548]

Guys,

I would concentrate on getting the pitch in the center of the blade right.

Cupping just kills the RPM out of these little motors. You can always grind

some of the cup out of the blades trailing edge. We have made strides in

handling and speed this year by watching the cup and adding more pitch

into the blade face. I like a pair of pliers with a rounded jaw on one side

and a matching crescent shaped jaw on the other side. You can coat them

with liquid handle grip if you like. This is the best way that I have found to

adjust the face of the propeller. Hopefully when Santa brings my Ipad 2

I will learn to do some pictures this next year.

Mike,

A cupping ball and brass hammer work much better trying to tip cup a propeller

than the crescent wrench does. Been their and done that. Mike Hughes sells

a nice set up for tip cupping.

Happy Holidays Fellas,

I have used both Mark, the pliers and the hammer and ball, both work well but I can feel how much I move the prop better with the crescent than the pliers when I only want a very small amount, maybe its just my imagination ha!

I clicked "follow this topic" hopefully it will send an email when a new post comes up. I dont see an email option?
