Viper R/C 1800kv Nude shots with dirty hand

Does suck. But I am talking to the "man" of Viper-RC now regarding my findings. I've been asked to test future rotors out.

I have been spoiled by Hacker, Plettenberg, Tekin and Neu motors. The Viper motor has some large shoes to fill.

Sounds like they should've made them 4 pole instead.

They would of had a winner if they made them slotless.

Update as of last nite. I ran the motor with a 20T, 0 Timing and super low brakes. The low brakes was a mistake, as I crashed my car taking out the servo. But in the short time that I ran it, the temp got to 125F or so.

Did a few test runs again with 0 degrees timing. Temps where much better.

Run #1 measured with Eagletree V4 150A.
Tekin RX8
0 timing
Stock brakes
4s hardcase Acepow
20T pinion
Ofna GTP 47 spur
Peak Amps 157.35A
Peak Watts 2069W
Continuous Amps 22.08A
Continuous Watts 324W@14.68V
129F


Run #2 measured with Eagletree V4 150A.
Tekin RX8
0 timing
Stronger brakes
4s hardcase Acepow
23T pinion
Ofna GTP 47 spur
Peak Amps 162.21A
Peak Watts 2039W
Continuous Amps 27.67A
Continuous Watts 400W@14.44V
142F

So it looks like I can go up another tooth with the pinion and still be good with temps.
