I was there at the track when the motor Bubblehead is referencing went up in smoke. The guy that it happened to is a local hot shoe, knows his way around motor and esc set up very well, and takes VERY good care of his equipment. One winding was burned up pretty badly. Looked like an old brushed motor that was way way WAY over geared (if you've ever done that, you know what kind of mess I'm talking about!
There seems to be an alarming trend popping up all over this and other posting boards about the RevTechs, especially in boost. First the issue with the screws (too tight and you have problems, and they seem to loosen up 'mysteriously' unless loctited in place with VERY little torque), now it seems that they're not performing with any longevity with boosted profiles, either.
I begin to wonder if it's a design problem, materials spec problem, QC problem, or if we've finally found the limits of torque/RPM/effeciency/amp draw with the current paradigm in motor design. Maybe the RevTech trades too much heat tolerance/timing tolerance/whatever for it's low end torque and improved RPM range. $90ish is a lot to pay for not knowing.
I know, I know, I know....everything has some growing pains. That's what R&D is for, not your friendly local hobby store track on race night. Wanna play "Bet your entry fees" with YOUR motor?
Seems like the D3 is the thing for boosted or a lot of added timing(for blinky) and the RevTech is for blinky with endbell timing, but the Rev isn't living up to it's promise. I'll take a D3 or an X12 and a few more teeth on the pinion until this gets sorted out.
Too bad tuners like Fantom are already abandoning the D3 in favor of the RevTech.
