Wildcat - I hear you can get hypnotized and they can fix your fears :D:D:batman:

I also hear going fast on the race track solves fears as well. :tire::tire::tire::cool:

If it loads, power it off using the button (Not by unplugging the battery), plug the esc in, and re-calibrate the ESC before doing anything else.

I have seen scenarios where people have had the ProGauge plugged in, made some changed, and unplugged it without saving or while it was saving and the ESC can loose it's calibration.

Basically, the ESC cannot see what it last knew was "neutral", so it won't finish it's power on routine. At least that is a place to start.

Still didn't work. It goes through the whole boot cycle but at the end when the orange and red flash, it continues to flash and won't finish. I can't get the pro gauge to connect at all. I have 2 of the same exact set ups and I tried different lipos and connectors and everything works. Just not on this 1 system.

About the only thing left to try is re-load the firmware. If you have a PC-Link you can do it yourself, if not, you can send it to the Service Center (fortunate for you is in CA)

He cant reload the firmware. he cant get it into program mode. He should just send it in. It is probably still under warranty.

Have you tried to power up without the esc plugged into the receiver?

Waiting for the webmaster to load it. Basics are the same as the vtx10 manuals except the profiles and default settings. There are specific profiles for 2s and 4s as well as 2 pole and 4 pole motors.

Hello

My VTX10 (black shrink wrap on caps version) stopped working last night in my 2nd qualifier. Speedo was Christmas present and third night on the track and has worked fine

I changed sensor wire, tried different motor, battery and no forward movement. I get a high pitch noise from the motor.

I tried recalibrating the radio, changing profiles with pro gauge. Speedo turns on normally and goes through regular boot up sequence but no throttle. It may have moved the motor slightly if I spin the wheels but it wouldn't go more than 1/4 revolution.

Could it be bad capacitor, or faulty sensor plug? I tried three different sensor cables and couldn't get it to work.

Speedo installed in 22 with Viper 13.5 and CRC shorty lipo

Help!

yes you can use the progauge on that ESC

check the solder connections on the ESC. check the wires on the v'port thingy. if one is sheared or cut, that may cause it to not work.

Absolutely! Works great. Maybe not as many tuning options as the 10th scale escs, but plenty to fine tune the power and drivability of the Copperhead systems. FYI - I am running he 5150 Copperhead in a SCTe with a 15t pinion and 100% on all of the progauge power settings. I have drag brake at 2 for just a touch of natural off power steering without having to stab the brake. Brake strength around 65% depending on traction. Narrow dead band, and linear throttle and brake. Never gets hot and PLENTY of torque and top speed. Awesome 4x4 Short Course combo! even better when considering the price! :nod:

Thanks. I changed all the motor and battery wires already. The wire from switch to speedo looks fine.

I would like to try it with a different capacitor board to rule that out before sending back for replacement. Anyone else have a suggestion?

I have a copperhead esc with viper 4500 motor that I have been very happy with but I now have a problem. When I power up I get a blinking green light and a steady beeping. I can get into program mode to hook up progauge. I load profile #4 via the progauge, click on save. Progauge says saved but f and r lights are fast blinking until I hit esc. The f and r lights stay steady on. I unplug the progauge, press and hold the red button to shut down. When starting again I get the fast blinking light and steady beeping. I can not get in to change the profile mode from the esc, I can only enter the program mode or turn everything off. What am I doing wrong here?

Sorry, problem solved, it seems my radio unbound from the esc. At least now I know LOL
