Just a question here but I think the statement is old. Is the PC V-link software ready to use on the VTX8?? I got the cable and ez link so I have both ways to connect. On A-mains web-site is says that the pc software is still under development. Is that just an old statement?? If so we can do tuning on the pc also or is it just for firmware updates so to speak.

Uh Oh, Did I get the wrong pc link cable?? I got a 6VSPCLINK1 but on the viper site it says a GVSPCLINK1. I hope they are the same can't find the other one anywhere??

Just hook it up! The PC link connects to the V-port on the output and USB to the input on the computer. If those connectors are different you did buy the wrong cable, but I highly doubt that because I think all Viper V-Ports are uniform throughout their speed control lineup.

There is one update for the firmware on the VTX8. If your speed control was purchased a while ago it probably needs to be updated. I purchased two VTX8's approximately 3months ago and they came with the new software on them.

2 factors lead me to that statement. First, because its sensored you can fine tune the system with features like Punch, Throttle and Brake Frequencies - this will allow you to get a better overall set up. Not waste energy or generate heat. Second, with the smoother throttle application, amp spikes are lower, with still achieving desired speed and acceleration, with will improved battery life. Which may not be a concern of dumping over a race distance. But more voltage in the pack, should mean less, if any drop off in speed and power available. Sensorless system can often cause you to pull the throttle harder than you want because you don't get that initial reaction.

I swear, this tech forum is one of the best! I learn something new almost every time I drop by. Thanks for the awesome support Nikos!

The pc link will fit all the ESC's.

Thanks, thought it would be the same but was unsure of the software on it guess its the same for the most part on all esc's from viper programming wise

No, the firmware is downloaded from the Viper website for each esc.

Yeah the firmware updates, but you can also set up your esc through this link also???adjust drag brake throttle curves etc. or is it just for updates

Yes you can make other adjustments as well. Nothing that you can't do on a ProGauge but you can do it.

Eta on the Viper motor?
September?

nikos2002 08-09-2013 02:11 PM

Thanks for the good words guys.

boborc - I think they got you in the right direction!!!

motorman - fingers crossed for sooner, they are making them as fast as they can, I want to say earlier, but until they ship, I feel bad committing to anything.

Viper, What size banana plugs to you recommend for use with vtx8 with 550 and 540 4 pole motors

bds81175 08-10-2013 06:30 AM

I would highly recommend that you eliminate the plugs and wire directly from the ESC to the motor. If you determine that you don't want to do this, 4mm bullets will work but you better make sure they are TIGHT!!!! Even slightly loose plugs (you might not be able to even feel it) can lead to problems.

boborc 08-10-2013 06:36 AM

I just like the convenience of unplugging for maintenance. Maybe I'll have to get one of those butane soldering irons, do they work good?? I frequent some outdoor tracks with no or limited electric
