Sounds good. Nice mods ! I have fiddled a lot with mine and found th best upgrade to be a collect type blade holder instead of the grub screws onto the shaft. Check out scatsbob previous posts. Good to know the .sk3 motor works out. Let us know how it keeps up!

By the way, what is the ring around the shroud? Looks like a piece of wire ?

[QUOTE=matchpoint;23723805]I turned down the cooling fins on a lathe.
I bored out the motor housing slightly
I reinforced the motor mount with a carbon fiber sleeve.
I PU'd the blades.
I bought the 8mm turnigy shafts off hobbyking that are 103mm long, had a new snapring groove cut.
Press fit in new shaft. Shimmed accordingly.
Reinforced top of motor mount with more carbon.

I have three of these. Here is #1 before dynamic balance.
