To avoid confusion and misunderstanding, our warehouse will send out USPS tracking number if they made a shipment that day. If you did not receive one, it was most probably we run out of inventory of the replacement item. Therefore, please check your e-mail box (if you provided it with your RMA case) to get updates. :nod:

I can't wait 'til the VTX8 comes out. I'm running an un-sensored motor in my TT and my MMP died again. This'll be the second time it's gone out for repair/replace, and my Sidewinder has also been replaced with an SV2. I'd like a better option for un-sensored. 'Bout ready to give up on Castle completely.

I have some questions (probably stupid) for the Viper folks:
- At a given can temp, is the rotor temp higher or lower? Is there a rule of thumb for a rotor to can temp differential? So-far, if the can is any indicator of rotor temp, this motor seems to run quite cold.
- Is it just me, or do your motors have way more torque and a far wider power band than other motors of the same size?

Hey Eric,
I'm only going by previous comments (as I've only run Viper sensored motors), but they're much more torque based than comparable motors. You tend to have to gear up a couple of teeth to get comparable speed out of them, yet you retain the torque and smoothness. 'Fraid I can't answer your other question(s).

Are you currently running Viper? If you wanna' check out a VTX10 / VTS set-up, look for the cars in my avatar pic at SDRC Raceway in San Diego ;) I'm usually there all day on Wednesdays for Wednesday Night Worlds™.

Eric,
-Yes, the rotor temp is going to be higher than what you may read with a temp gun on the outside of the can. The difference can vary depending on gearing and type of chassis being used.
-Yes again, our motors are torque based and do develop quite the punch, but have a great power curve to be able to control it.

Yes, I have their 17.5 in my SC. I've just been worried about the fact I don't know what the rotor temp is, and I don't want to shorten it's life. So far, I've been extremely happy with the motor, so I obviously don't want to kill it, and the way I've been gearing it would easily overheat many motors... I plan to be there on Wednesday, too.

What can temp should I be aiming to stay below for safety? In this case, it's in an SC10. I've been seeing a plateau of sorts where with any of four consecutive pinions it comes off in the 140-145 range (indoors), but below this range it drops about 15 degrees per tooth (drop three from the low end of this range and it's right around 100). Stranger-still, the last main I ran she came off at 127 while running one of these higher-range pinions (33:75). Obviously, these are all can temps...

alright cool, im not sure if mine were sent out because i didnt get a tracking deal but if they were thanks again for all the help!

got my motor today and looks sweet, just waiting on my esc's and then head to the track!

Got my 13.5 all set up in my 4.1 and it seems like it will be a runner! It did take a while to get some power out of it though, seems these motors like alot of timing on the MMP at least.

Well, It was a long weekend at the 2011 Jconcepts indoor summer nats. My Viper 2050kv motor ran great. Never got over 140. It was 101 outside and about 84 inside. I took 2nd place.

When you get it be sure to scope the settings I posted earlier in the thread.

I will forsure, how did you guys do at the hotrod race

The hotrod race is this weekend, Jconcepts race was last weekend...

Oh lol thanks, did you happen to mail the escs out rage?

ready to go this weekend!!!
