Oh ok so what floating servo mount can I use on a 417x chassis. Also what final drive(or spur pinion combo) should I start off with, ill be running in 17.5. Also has anybody tried the Smokem 417FX chassis I'm looking towards that and the Smokem floating servo mount, or is the Raceberry the way to go I just don't want to spend $200+ on a conversion kit or is the V5 cheaper to go with. So if anybody has other options ill appreciate it.
