We ran a 2200 BL Revo for a while.... had tons of issues with the driveshafts breaking...blew only a couple of diff's, replaced the arms with RPM.... We tries loosening the slipper but then the performance suffered as the slipper slipped too much..then when we tightened the slipper the shafts would snap.... couldn't find the sweet spot between the slipper being too loose or too tight...seemed no matter what it was never right.... My buddy ended up giving up on the Revo and converted a Mugen 6T to BL and has never looked back..much more durable platform then the Revo was...
