That Hobbywing EZRun motor is allowing me to take advantage of what the ET410 has to offer. If coming out of corner just right, WOT is only accomplished for maybe a half second on the track's smoothest straightaway. Most days I turn down the throttle EPA to 90% to better keep control on the rough stuff. My Speed Passion motor is now officially retired from 4wd use.

O-rings
 

Everyone bought up the Axial o-rings last year, and I had to go searching for alternative shock seals. I've been using HPI's#75075 - SILICONE O-RING S4 (3.5x2mm/12pcs) in the shocks for the past six months. Those things are on the money! My shocks are performing the best they ever did. I'm not going back to the x-rings, that's for sure.
