So, I tore my truck apart to figure out what was going on in the rear. No bent hinge pins, diff was still smooth, nothing out of line, gear lash still good, out drives and coupler still good (a bit worn, but still good and not notched), antisway bars still move free and do their jobs. Shocks were smooth, but then I finally think I found it. I'd developed a slow leak out of the bottom of the left rear shock cartridge, so it isn't full anymore. I've never had a shock issue on these things, so i hadn't bothered to check that, doh! I'm guessing this made it soft enough that I started getting the chassis slap kick flip action when I didn't land just right and used throttle to fix my next jump takeoff, and of course also why it was odd handling in the turns.

I took the rear diff apart anyway as it is my lightest diff oil (3k), even though it was smooth, just to make sure everything was good. It was still full, not worn, and while the fluid was dark, I could still see through it.

Not bad for about a year with 3+ races a week. This is the biggest reason why I went Tekno and don't miss the Losi at all.
