Got to watch Fred Perkins run the VTX8 in his Mugen MBX6 ECO with the new firmware for the first time. All I can say is wow, what an improvement. He had more power, it was more deliverable, and he had zero temp issues. If you don't have the newest VTX8 firmware (A61), make sure you get it!

Just back from a refreshing weekend away with the family -- they even got me on a zip line!!!! That was crazy some fun! Back to the questions:
sickpuppy- definitely check your profile - sound like your on profile 1 - I have done that by accident and the car wont to anything because its looking for a 4s battery. Its actually profile 3 - that is for 4 pole motor, 2s battery. Profile 4 is what Steve probably uses with his 2 pole VST motor!!!
hellssephiroth - sounds like its just that issue with the gearbox needing the extra gear, can't imagine its that much, in the grand scheme of everything rc/ And it will work really well. I run mid motored cars and trucks (X Factory), they have a great feel on track.
I also heard Fred was hauling the mail at Vineland over the weekend!!!!!!!
OMG - Gear up -- at least one tooth. Your esc temp is higher than your motor temp. The motor temp would be OK, if esc temp was not so high, I would like to run my esc about 66º-68ºC under normal conditions or lower. Outside temp has a little to do with that also, plus cooling holes in the body for both motor and esc.

Loaded question -- because it also relates to gear ratio, outside temps, driving style. General terms - higher freq would incrase esc temp (more switching on esc's parts) but feel smoother, lower freq would make motor feel aggresive, which could raise motor heat. Not a definitive answer, but hope it makes sense.

If you are still having troubles, try re-setting up the ESC. Set end points at 100 and rebind

Wildcat - what are you reading at hotter temps? especially after a qualifying heat or main event. Very different from practice. Generally, with any motor - club racing I try to stay around 150ºF. This is a good temp range, generally lets the motor last longer. Now at a big race, everyone has their own definition of a big race. I will run more temp, run harder try and find that limit of lap time. But if I am at 170 with slower lap times, went too far.

They should be blinking, should be solid. It does take a nice push of the button, some think its really delicate but it take a nice "push" to active the button on the VPort.
