I recently got a used Tmaxx with Dynamite big block conversion metal skid plates metal gears in tranny al servo mounts and I want to put a .27 sirio in it, but from what I've read I will need to dump a lot more $$$ into the truck to make it last. Maybe as much as $900 into it. Then I began to think I could buy a new Revo and put a .23 sirio in it for $750. What do you guys think??
