Savage Flux Xl Build

so it would be easier to use the FLM Flux extended tvp's ahh a uknown~unknown ! i figure with the tranny and the tvps not matching up even close u might have a "heck" of a time working around them and when done will they take the same abuse ! i didn't think the kershaw stuff was bad it just seemed like i was pressed so thats why i didn't stick with it, i was really a good lipo and a pinion away from a test run. i had been eyeballin the new chasis for like a year now and since the flux had been out for a while that made 2 options that was better than the can sitting up so high on the chasis. i was looking at you spur and 44 sounds like a blast i have the 47/20 on my truck now but would like to use the 44 becuse at the moment i'm stuck with my current motor/esc @5s. i am considering locking my tranny because i need that servo for my DM-1 and reverse wouldn't hurt but i'm worried i might burnup my esc "LOSI Brand" before the holidays are over and i can get a MMM. when you get a chance shoot me a link where i can learn about the locking the tranny.
