If you get another opportunity to try one, you should do so with no reservations. I have yet to find someone who has driven a Viper ESC and said 'oh, I don't like that at all'.

I dont work for Viper and cant say for sure that I am 100% correct. But no one really makes and markets a sensorless setup for racing. They say you can race with it. Does not mean its the best for racing. I think once you run sensored, running sensorless is a very hard thing to do. If they ever get sensorless to the performance of sensored, I am totally in. I had a motors sensor board go out and it killed me esc. I was like wtf. But people told me yeah, that happens often enough, but its normal. Of your sensor cable goes bad mid race and your car stops in the middle of the track. That blows also. HW and maybe tekin over come this with dual mode. HW for sure. I unplugged my sensor after powering it up. and it kept running, but started cogging. It dropped seemed to automatically drop its self to sensorless. I think the tekin might only work in the mode you set it for. So if you set sensored, it wont work if the cable fails. There is no perfect esc and everyone has failures. it is how they handles the failures that maters. So far viper offers me 90% of what I want with a great warranty and support. Tekin only offers me about 60% of what I want, but they also have good support, but 1/2 the warranty. Tekins are ok, but you will never convince me that counting led's and blinking lights is better than a progauge that also acts a servo and lipo checker. The fact you didnt like a sensorless system does not surprise me, but I would not have written off the entire company or product line.

Putting together a Schumacher K1 right now. Plan on running it on a slightly larger outdoor track and a small indoor carpet track. Switching back an forth this much what Viper motor would you guys suggest? Running it with a VTX10-BE

the exception might be the sensorless setups. It is pretty common for drivers who driver sensored to hate sensorless after the fact. I have never owned a copper head, but feel free to throw one at me to test and review, lol. If someone local owned one, I would ask to drive their car. One guy has a vtx10r with the viper 4.5 550 in a scte. I would like to drive that. I might ask this weekend.

I hooked it up to the programming card and i get a connection error every time. The little end plugs into the switch only 1 way, the end that pugs into the cards only lights up 1 way also. every time i get a connection error. I hooked it up to my lap top and it doesn't read the esc. Any idea's what i'm doing wrong? thanks

Are you racing club or large events? I was mainly pointing that at sponsored factory drivers. No the club folks. We have 3-4 traxxas that race with castles, velium and other sensorless 4 poles. They prefer sensored, but prefer the lower cost more, lol. When Cavilari and Maifield run sensorless, then I know the world is ending.

I'll say this...the sensorless feel on my Copperhead is a lot closer to sensored than a lot of other ESC's i've tried, Velineon included.

yeah, I have heard many people that. When I was looking into SC 4x4, I was looking at that system because of that. Plus I only do club racing, a $300 system would do me no good. If I ever see one at the track, I will ask to test drive it. But unless it completely bad, how can you go wrong for $99 lol. Even I could stand a little cogging for that price.

i'll try to take a video this weekend of my truck. the trick is getting the radio in frame so you can see the trigger...sensor/sensorless is a feel thing. tough to show on a video...but i'll try
