tenshock brushless motors

I would like to see if someone is using it for 1/8. I know I have a local guy who's bringing it in direct from China but will let him try it on his truggy and buggy before I decide on things.

Just ran the tenshock with the mmpro. Geared 16/42 which is about 35mph without ballooning. Ran onroad, in the sand and in grass. Running off-road and in the grass temps slowly rose to 118f, and when I ran onroad the temps would drop to 100f. I didn't push the car offroad beyond 118f just to be safe. I don't think the fan on the mmpro ever turned on.

edit: didn't change any settings in the mmpro before running expet setting the lvc to 3.2v/cell. 50% brakes was a bit too much, changed it to 30% for the next run

Hello Folks,

Just did some testing of the Tenshock 6 pole motor X802 (2400kv)

Car Setup
Slash 4x4
Geared 21/52
Proline Streetfighter Tires (4.5" diam)
Trackstar 150 ESC
0% Punch
3s 6000mah 25c Turnigy Nanotech
Ambient Temp 55f
Theoretical Speed (scriptasylum calc) - 51 mph
Recorded data from an Eagletree v4

1st run
No motor timing
Temps after 10 minutes of high speed runs
Motor 120f
ESC 85f
Peak Amps - 177.5
Peak Watts - 1780
Min Voltage - 9.98
GPS Speed - 54.4 mph

2nd run
Added 16 degrees of timing
Temps after 10 minutes of high speed runs
Motor 150f
ESC 95f
Peak Amps - 175
Peak Watts - 1801
Min Voltage - 9.98
GPS Speed - 55.5 mph

Not sure what to make of the fact that adding timing appeared to change nothing except raise the temps, was suggested that these motors come alive when its added

Not bad results though, quite happy with the motor, will push it a little harder and do some 4s testing soon

Cheers

hi,

had my first runs with the x801 with 1900kv on 5s in my LRP S8 TX Team Truggy. It's supposed to be strong enought to run the truggy, and I have heard quite good things about the Tenshock motors.

Well, in the beginning it got far too hot, with the recommended high timing of about 18 deg., and later with 26 deg. timing. I think, gearing was far too big, too. my fault. ESC is a used HW ezrun 150a. Like that, temperatures were around 80 deg. c and more (185 f.), with timing of 26 deg. about 90 deg. C. I am using a fan on the motor.

I think, the timing and setup for a buggy is different then for a truggy, so I tried lower timing.

I was told that they are getting a bit hot, but that was far too much. So I have changed gearing to 16t, the same like with the Leopard 4074 2000kv. The leo always had around 55 to 60 deg. C, with fan (140f).

With lower gearing and lower timing of around 4 degrees, the tenshock got a little cooler, like around 65-70 deg C (158f). Slightly hotter then the leo. well, we had a worm summer day here in Hamburg.

Performance was good, quite similar to the bigger Leo 4074, probably a bit more torque, not sure. both have the same sized magnets I think. the x801 has a power-characteristik quite similar to the Leopard. So far, it is hard to tell if the x801 is that much better then the leo. the x801 is basically a 2240 motor. The x802 has more slots. There are also long versions available I think.

But that's just a first impression so far, and I have to test some options on the esc. I loved my xcelorin 1700kv, which war for sure not any weaker then the leo or the Tenshock.

For a buggy for sure a great and powerful motor, and probably for a truggy as well. more to come soon.

so I had some runs again today. I tested timing of 11,35 degrees, and the temperatures were much better. Worm summer weather with about 30 deg. c, the motor got between 60-69 degrees, round about 156 f. This is ok, still I use a strong fan.

I think there is some more torque compared to the 2000kv Leopard, which is aready a great motor. So far, the x801 seems to be a great motor.

here are some pics comparing the Leopard with 2000kv and the x801 with 1900 kv

the (smoked) Leopard is longer


left the Leo with smoked windings, left the Tenshock x801, wich offers more space for the bigger magnet. The x802 has more slots


both are 40mm long but the tenshock is thicker, six ooles of course


no kevlar or carbon fiber is used:


The bearings measure 5x16x5 mm, just have ordered some ceramic ones...
