+1 . I agree to, but try a new sensor cable or check the sensor area for breaks.

I tried a different sensor wire and did'nt help

I tried it with the velineon esc and didn't work well either

traxxas is worse then castle.. try a novak kentic or tekin rs or something race worthy.

Also you mentioned it got hot...How hot? Did you temp it? I've had a SP and LRp 13.5 motor get rlly super hot when I first started brushless and they nvr worked the same again.

It didn't get super hot but enough to be of concern...I didn't have a temp gun...but it was cogging from the get go. I don't have a Tekin or a Novak to try and test with.

The issues sounds like a bad sensor board on the motor. If more than 1 esc is seeing the problem this is the most likely problem.

Funny, I remember not long ago how you were commenting how well the VXL worked sensored in your Hyper 10 hahaha all be it with a motor other then a viper :)

Should try viper esc:)

also it was a 550 can and it didnt work better then the rx8 i had in it after that.

i have one.. but its not out to the general public yet.

mine is wired into my 8.5 in my b4 hauling butt ready to race this weekend.

You do? Wow post up a pic.... this is so cool. Wonder what your going to put it in?

I can post a pic when I get home, as well as my prototype 8th scale motors if interested.

Well guys I didn't have any luck with the post office and my lost viper 7.5 so I guess this one is a lost case and down a motor:(

Oh cool, I saw your B4 at Rob's house the other day and I didn't notice a Viper esc in it. I think it had a Tekin in it... anyway right on man. Where you going to race at this weekend?
