I have a problem with a new vtx8 and a vf8 motor.

when I go from full brake to full throttle , its like a off then bam 100 and nothing in the middle it has gotten so bad that I have to move my finger really slow to get the car to run . any ideas

What radio and what software version would be helpfull

sounds like it's not calibrated correctly. Start from scratch. Go to a new model on the radio, rebind everything. Set all your end points to 100. Rebind the ESC to the radio and then try

mt4 radio v64 on esc

I have reset the radio re bind and recal of esc still the same .

it only does it from brake not from neutral

the malfunction only happens when I set the motor direction in reverse .
when I set it to normal it works perfect . changing it in the radio has no affect on the direction . please tell me that it is a soft ware glitch and can be fixed

I run a rb e one r and the motor has to run reverse.

grr

No because it's sensored. Did you recal the radio after you reversed motor rotation in the esc?

yes

I rebind the radio ,and recal the esc works great when I set it to normal
when I set it to reverse and recal,which my car requires . maybe I have a defective esc or motor guess I have some phone time to look forward to grrr

this sux

I was hoping someone might be able to help?

I was at a meeting yesterday and in practice all was good. For the first round of quali I turned on my VTX10r BE and it made the usual noise. I had steering but the throttle did nothing. I took off the shell and the button has 1 solid red light on the 'P' and no other lights. The button doesn't do anything, even holding it down will not turn of the ESC. It has A64 firmware on it.

did you try reversing the motor in your radio but keeping it normal in the ESC then recal?

ya tried it all . call and talked to tech at viper nice guy .

we are guessing that it is a sensor in the motor causing the skip as all these motors are set to o so off in the mail it goes .

IM thinking I can flip the diffs because it works perfect in normal but the problem with that is my buggy uses helical pinions on the diffs so im not sure .

but it would be nice to run motors forward . French buggies go figure lol

on the bright side I have gotten a education on sensord 1/8 buggy esc and motors .

My buggy is almost ready to be wired up for power, one thing I noticed: There was no instruction sheet in the box for the VTX10 combo. Had to wait till I got to work and print some instructions found on the site. For the 10 cents it costs it would have been nice, no internet in my workshop.

Did you look under the cardboard in the bottom where the stickers and double sided tape are? I'm pretty sure that all of my Viper ESCs have come with instruction sheets.

weird. All of my esc's came with instructions.
