+1, they work great. Just don't use Kyosho X rings..thats it. I have years of experience and know for a fact they don't work, if someone else "got them to work", i'd like to mess with it myself...because it will suck air.

On a lighter note i used the lunsford titanium quick change mounts and love em so far, using the RTR plastic bushings and a 1mm blue aluminum spacer between the plastic bushing at the hex on the lunsford mounts did the trick, i only had to grind the front tower a bit and used no lower spacers
