Thanks for the info Pete, just ordered up some DW foams and some tuning rings. That's really the only place I find the Wraith lacking is high speed handling. Since I have multiple sets of wheels and tires, I'll set up one set for all out crawling and one for higher speed / bashing.
Pete, from my research and experience, every Crawler and scaler needs a standalone BEC. It's not the voltage that you have to worry about, it's the amperage, and more importantly, the amount of sag when under load. I even ran CC BECs in my race rigs after a brownout, never had another issue...
Pete, I killed a Hitec 7950TH in the Wraith and when it let go I grabbed the horn to check for stripped gears and heatsinks branded me, it was smokin' LOL. Turns out the adapter I used to wire in my BEC shorted, and it fried the servo. I soldered up my own adapter from heavier gauge wire, and...
Pete, try some CI dueces wild foams in your next tires. I've heard they're a great compromise between crawling and go fast, made for stuff like the Yeti and rock racers in general.
