Hey Mr Holmes, nice to see ya outside of rccrawler.
I've loved my FLM Savage ever since I put it together. The Savage can seriously take a beating. One of the guys who frequents my lhs just put an XL chassis on his Flux and it looks perfect. He said he had to grind a bit to clear the motor, but it looks factory. You really need to have a longer chassis for more stability. My FLM will still wheelie on 4s easily but it's a lot easier to control. I've got a spare FLM chassis for sale cheap if you're interested. It was for my top spped savage, but they moved the chalage to North Carolina last year so I dismantled it.
PM me if you're interested.
