it should say when you select a profile.
i think my vtx10R says it somewhere when you go to different profiles.

I swiched to this brand recently and now I own 4 VST/VSTR/VST8 and 13.5T,17.5T,6.5T,8.5T @ 2each..

The funny part is, he probably never set the cutoff correctly and sent back a good esc/motor.

I can tell you that you have never contacted me or I would have gotten you help. As a team, we support the paying customer the same or MORE than we support each other. If you have a problem, we fix it or we do everything we can to get it fixed for you.

***EDIT*** I see Nick already addressed this....

If anyone EVER has an issue, don't settle for not getting a response to this thread. Remember, we are racers too. We don't always see every post right away. But we do reply to all PM's and emails.

Hello, I just ordered a VTX10R BE for my DEX410V3. I will be running a Reedy Mach2 6.0 I am excited to try out the Viper. I have been using Tekin forever and decided to try something different.

PS - Mammoth Hobbies has a GREAT deal on the VTX10R-BE with Progage ($165)!!

Sooo... I am sure I know the answere, but has anyone ever tried a 4 pole with a vtx10r? even a lower kv 3800 ish motor? Because I hate myself, I am thinking about getting a sc10 4x4 and I have a vtx10r doing nothing atm. I am sure the official answere from viper is no, becasue it says 550 2 pole 4.5 limit on the site. would a 4 pole 3800 kv draw more power than a 550 4.5 2 pole?

That's the esc I'm in the market for. Couldn't find that deal on their site or I'd have been all over it.

My 3900kv Copperhead Viper combo really drained my 25c Duratrax packs.
I was lucky to get 7-8 mins outa my 5000mah. Maybe 6 mins outa my 4000mah packs. Im only going to use these packs in 2-pole motor applications.
Time to invest in some new batteries. Im going with trakpower batteries.

Since it's arrived there now to get replaced im only guessing
not to use a 4 pole motor in a 2wd. Because of the severe battery drainage.
When I get my replacement I'll probably save it as a backup for my SC10 4wd. Because I plan on getting the 550 4500kv copperhead system anyhow.
But the SC10 4wd is unique because you can get by with a 540 4-pole system it comes with a 32 pitch gear and 48 pitch spur in the box. You dont really need a 550 but I want more power anyhow and being able to run 32 pitch gears.
There's people here running the SC10 4wd with a 2-pole motor and I wouldnt do it without a fan on the esc. They have to be running a 48 pitch spur gear.
4 pole motors obviously drain more power than a 2-pole motor.

I would go much higher than a 5000 mah in 4x4 sc. We race 10 minute mains around here. I would not go below 6000 mah in that class.

Your right, I guess it was on sale when I bought it. It just came in today, it is a very nice ESC, well built and very nicely laid out.

Testing before the SC Showdown last week I used 6400mah pack for 20 minutes!!!!!! Well I crashed a few times, maybe it was 17. In my SC10 4x4.

anyone that has raced a lot with sensored esc's, can you compare the power band of the copperhead systems? I have never run sensor because I always figured they were bad and for bashing.

I have run both the sensored systems and Copperhead systems. Sensored is much smoother, better throttle control, easier to driver when you are trying not to spin the tires. Copperhead is little more abrupt, the power comes on fast and furious. One thing to point out about Copperhead is that our unique software design helps to control the "cogging" that some unsensored systems have, it has the feel of being almost sensored.

is the abrupt power from the 4 poles or the sensorless design.

Both!
More so from the power, but being sensorless adds to it.

It really is quite smoother than say a Castle/Duratrax system.
