I am amazed you haven't shredded a diff yet, I killed a rear diff on my Flux XL with a 1520 and 6S within 5 minutes for the first run, and within about 8 minutes into the 2nd run I killed another rear diff, along with something in the trans and snapped the set screw pin holding the drive cup to the rear output of the trans. Geared for a conservative 37 MPH (16/44 pinion/spur) with HPI bulletproof diffs. I know the 1520 has alot of power, but I didn't think it had THAT much.... Any suggestions? I think I am going to have to go with FLM bulkheads and HB diffs to solve the diff shredding issue, unless someone can clue me in on a good fix for this?

Sorry to hijack the thread, I am just amazed at how many people are running 1717's and 1520's in XL's without issues with the diffs or trans, yet I've shredded it all in 2 runs.
