The flats are a good idea but I kinda wanted the smooth hub look since the engine is going to be exposed. I asked the guy if he could knurl the top but he said he needed a special machine but he didn't have one. I cant really complain to much since he made me the part for free.

thanks for the sand paper tip. I have to go to home depot later today and i'll pick up some yard stick and some drywall sanding mesh. I also have to go back to my local machine shop to get the crank shaft threaded.
It looks like the servos get here Thursday but I still have to buy 2mm coroplast.
