I run on a high bite indoor clay track as well as a medium bite larger 1/8 sized outdoor track. I will eventually be running the exotek chassis, so the truck will have some weight, should that have a bearing on which motor to choose? LMK what you guys think!

If you go with a plastic idler as you sit now? You'll blow idlers instead of Spurs. Which do you want to tear down and replace?

A 32p correctly meshed Slipper slipping (manual: 2 feet on high traction suggested) Truck; will not destroy spurs, idlers, diffs, belts, etc. (of course, other than different variable issues such as pinning the slipper causing excess power on the plastic parts that were not designed for it.) I'm not talking down on anyone, or attempting not to. But we're locking these rigs up. Having the slipper tightened up is fine, but it must still slip for landings, punch control, and etc. That's RC 101 to 'not' lock that tuning option. (unless for a very specific purpose.) Plastic, metal, Unobtainium, it doesn't matter. When a Basket is installed (or get your slipper to work without one like me), you still have to have it slip. Otherwise, Idlers, diffs, Spurs go pop. Something has to give.

Sourdiesal has spit out two in the last two weeks, i know for sure the slipper was set right on the first one cus i set it? still think AE changed matl spec along the line.

Marcus, they are racing at Mike's on Friday. Ronhoto finally broke his Losi out there this Sat, TQ and win, not sure if he's going Friday. I TQ'd and won at Katy Sunday. Like the truck, but it's probably only 80% of where I'd like it to be. Don't think I would have had anything for Wipf, but he didn't run SC. He was quicker when were practicing with the SC's. Mine was more consistent, but I don't think it would have been enough. For a first race with it, not too bad, I need to find some TnT time. Doubt I can make Friday, but I bet Smiley is there. Just make sure it's a 10 minute race and you're golden LOL.

The pro4 is the best motor i have ever purchased, its that good
