Well I was considering the FG MB till I mentioned it to a track owner in Easley SC and he said that the guys who had bought FG's were selling them and had bought Firehammers.
Mainly because of no replacement parts.
Infact if you call here they have a FG for sale.

Anyway, now that I have found a Firehammer without the cheap radio and servos (called a XTM) I will buy one.
Also
http://www.molzermoweryracing.com/index.html is selling conversion parts if you need them.
The biggest thing is Tower Hobbies sells these, not FG then this is a plus in my opinion. They make a big impact on buying stuff in the states.
