hope them vtrax10r come out soon!!!! I have been holding off buying a new speedo. I have the motor now I need a esc to match it.

So I am interested in picking up one of these motors to try, but I am concerned with the really low Kv ratings. Comparing the 10.5T to a Tekin 10.5T there is 1400Kv difference:confused:

I understand there is much more to a motor than KV alone, but what about spec classes where gearing is often already at the limits of what will fit?

I like the look, and I like that you guys are here helping racers, but you gotta tell me the numbers are VERY conservative or something.

I can tell you with the viper motors you have a bit more room in gearing then with what you have now. I can honestly say the viper motors are hands down better then my losi and my novak. I had a novak 13.5 on my cougar and ran a 28 pinion, I swapped in the viper and used the same gearing and it was exact.
I had lower temps so I was able to bump up to a 30 tooth pinion and got a bit more speed out of it. all in all I will be running only viper for electric.
I just recieved a 8th scale motor and will have everything installed in my losi tekno conversion in the next few weeks and will be testing them on 22 volts!!!!!
cant wait!

you can run a bit more timing to gain the kv with the same gearing..

Typically the Viper motors Gear 1-3 tooth more then other motors of the same wind.

in 13.5 buggy
i ran 26/75 in ae b4

i now run 26/78 and my car feels the same.
but my motor is more efficient on bottom end, And smoother through the whole power band.

Just curious,, i run a cougar also,, my normal gearing for a 10.5 was 26/81,, since i had no other options at the track for spur gears when the motor was handed to me to test,, i went with 28/ 81 which was the max i could squeeze in there,, are you running a modified topshaft or did you find spurs that work with the stock topshaft??

i am still waiting for mine! lol

They should be out pretty soon with the Results of the snow birds

Weylin and the Crew should be back home and online tomorrow!

forgot to add what i was testing was 17.5 un boosted

what esc are you running?

SOOOO AMMMMM IIIIIII!!!!!!!! CANT WAIT :sneaky::sneaky:

I geared up 3 teeth thinking...wow I would never try that with any other motor and ran hard for 6 minutes both 17.5 and Truck was a blistering 88.5 and SCT was 101.8 lol.....I am now waiting on smaller spurs because I had no more room to gear up anymore.............Come on SPEEDO's...I am loving the new motors ..what a difference:tire::tire:

So, ah, couple days after the Snowbirds, any new news? (even if it means later?) Waiting on ordering 2 10.5 VST's, a vtrax10, and a vtrax10r :D.



Do have a question though on the ProGuage. I believe I saw earlier in the thread, that the plan was to include the ProGuage, I was wondering on what? With the ESC's, or only packaged in with ESC and motor combo's? Our local track is under construction, so not in a major rush so I've been holding off on getting motors, so I could get a combo. Or even if the plan is to offer combo packages?

2 days after the snowbird weekend.. i am Sure the team is still trying to get everything home and sorted out.

Weylin will update the thread when he gets back online! :nod:

The kv rating is not comparable from company to company only within a specific company. So I would not worry about it. 10.5 is 10.5. Personally I would stick with tekin but that's just me.

Marcus you coming this weekend to DRC?

The ProGauge will come with every speedo sold. It will also be available seperatly, and yes, they will offer package motor/esc combos. (this is all what Weylin has told me; if it changes.... im sorry) Last I heard, the speedo's are going to be pushed back a tad, got some other things they want to work on before they release em.

Get your self a couple Vipers, they are bulletproof man!

In fact... we have quite a stock of Viper motors at Premiere!
