You guys might want to try it before you pat my back
It seemed to work but now I'm back home and only have the livingroom or my cluttered garage to try it. Like I said above it seemed as if I had alot more forward speed but my battery was about dead when I thought of it and that was at midnight so I flew it for a very short time. It needs to be verified as a workable mod by more people but please be careful. I don't know what size bit I used but it fit the stock holes tight.
I've got another idea but I gotta try it first and I'll be glad to share as soon as I test it.
