bustitup crt.5 build

I"m starting to put this together....I put these Imex Claw Dawgs on temporarily untill we get the 17mm fix then I think I will go with badlands on bead locks....picked up two Feigao 9l's on ebay tonight...got a clear body I'm kicking colors around but it looks short allready so when I get mikes new extended chassis I will need another body for sure

whats a good cheap upgrade from the ofna sx0001 servo? or is it good enough?
