nevermind i will just call viper this morning .... the rx isnt an issue .... its a 603fs .... and i have ran viper for 2 years now and have unplugged a million times and turned off by the switch too ... never have i encountered this weird glitch .....with a red of or a Black ...


i also have another complete copy in my buggy .... plus a backup vtx10 red that was bought when they 1st were released....those dont do it ....

anyone have a good setup for sc10? just started running it. I have buggy and 4wd figured out. I went with my stadium truck setup and lowered the pwm some. I am running 17.5 blinky.

Viper has the worst customer service I have ever seen. I ordered a new vtx8 and 4.5t xl motor got them both and neither one of them work from the factory. Been over a month and Im still waiting on my motor. I called them and they said I needed a backup system? So if you buy from them there telling you to buy 2 because one of them probably doesnt work. They SUCK.

You are in the minority talking about them that way. They will bend over backwards to help people out.

Nothing about this seems right. I can only see them taking a month if they are out of stock. Also, the motor and esc were DOA? That is possible, but very unlikely.

Have you contacted either our customer support lines via phone or email to help resolve the issue?

If the system is brand new, and you were able to calibrate it to your radio, I would check that you have the system set on Profile 4 (2s battery, 2 pole motor) as the instruction indicate. If you did not change this it would not work because Profile 1 is for 1/8 (4s battery, 4 pole motor) and the voltage setting is much higher so it make you think it doesn't work, because it won't respond when you pull the trigger. Please PM here or contact our support services, we'd be glad to work on it to help you.

Agreed. I did the same thing when I went from e-buggy to short course. I was lucky enough to look for a cut off setting and find it. The speed control will not work otherwise.

"I would check that you have the system set on Profile 4 (2s battery, 2 pole motor) as the instruction indicate"
When I got my 1st VTX8 for my sct I didn't do that and it was set on 12.8v cutoff and I thought it didn't work. LOL

Sorry, I was away at the SC Showdown over the weekend (check out the great reports on LiveRC.com) - couple A Main finishes and podiums by Viper products in 17.5 SC, SCB, a few near misses in 4wd SC - good racing weekend, so I have to catch up on some of the thread.

re-calibration issue from other page -- the calibration goes by the end points of radio (which are transmitted in signal from radio), they can vary from model to model in the radio (you can actually test this with the ProGauge). I would recommend either re-binding your radio or use a different model. On my Futaba 4pks, my model 5 will not calibrate any Viper esc if the throttle trim is set at 0, I have to move it -1 or -2, or +1 or +2 for it calibrate.

"sticky", difficult shutdown - we have heard that, the only thing that I have personally seen with this is, if the system is not at neutral, it will not shut off (it thinks its running, even though it many not be). If you see then, check to see if you see the green neutral like on the esc.

That is true Nikos, I have seen it not say neutral with the radio on and I will sometimes recalibrate. But for me, if I turn the radio off, the neutral light turns off and it typically wont shut down. Now some people might say, why turn the radio off before the car? While that is true, lol. Sometimes in a hurry ya know. Plus sometimes I use the progauge to setup the esc while the radio is off. Then, I either need to power on the radio or just simply unplug it. Since the off button is the main thing i dislike, I can live with it by simply unplugging the esc.

Something is amiss here. Viper has ALWAYS been great to me the 2 times I've contacted them. Both times were user error (usually is with me) and they literally walked me through my issues (self created) and I couldn't be more satisfied.

Stu - sorry missed your set up question. 5000-8000 throttle pwm (see what you like best), 100 punch, 100 forward power. 75-27 or 28 (2.60 gearbox) is always my starting point with our motors. BTW, qualified 20th at SC Showdown running a 17.5 blinky!!!! If I only could have gotten that run in 17.5 class I would have been in the top 10!!

did you CALL viper?
this is an absolute Absurd comment.

Thanks, I'll set it for my 4s batteries, I'm over 6s, which I mucked around with when I got my Vorza,now it's about the racing!

I don't know what FW I'm running so I've ordered the cable. Will check if there's an update.

thanks Niko .... I use the same radio system so i will just change models for that car..... i wasnt too worried about its the end of the indoor season around here and that system Won a season championship for me !!!

and Whoever said Viper's customer service was less the stellar is WRONG .... I might be bias cuz i am local to them but its been top notch everytime I have had an issue or an upgrade !!!!
