If you're running this in a truggy, you're running the wrong motor. You should be running the 2200kv truggy motor at max, not the 2650 buggy motor. Personally I'd run the 1500-1700 in 4 to 5s before running a 3s setup in a truggy

why is it the wrong motor? Why must it be a 2200kv at max?


When I first started ordering motors for the conversion, I think I was looking at the 2.5D AND the 1.5D. Figured I'd try one first and see how it went, so I cancelled a motor from the shopping cart.

Only to find out after the order shipped that I had cancelled the 2.5D instead of the 1.5D. I spoke to Mike as well and he said that the 1.5D would be fine, but just to be aware that my battery and gearing options would be limited. He also informed me that the 1.5D is an amp-monster.

So far I haven't had any major problems with temps in my set-up. I mean, aside from just this previous race session, my electronics have been happy. Average temps (on an 11T pinion) for everything were as follows:

motor: 126-135 (no fan)
ESC: 130-150 (MMM v3)
batt: 105-125 (3S, 5000mAh, 25C) - the 125 is usually after a rather vicious bashing session

Now bear in mind that most times when we run the ambient temps are usually hovering around 95-96 degrees.

I could be wrong, but I think the set-up is quite happy. For this race session, I moved up to a 14T pinion...which would explain the higher temps.

Am I misguided in thinking that the temps are ok?

The neu was probably ok, was it a 1515/1.5d? I was refering to the tekin motor, the 2650 is designed for the buggy not the truggy, its even listed on tekin's site as such. The highest kv motor on the truggy list is the 2200kv, Size wise, the truggy motor would be better at handling the load

As far as the temps, you seem to be ok. I was refering to the tekin motor being a buggy motor, you even said it run a bit warmer over the neu, I think it was because it was a smaller (shorter, as in a 1512) motor than the neu

affirmative...the motor is 1515/1.5D/F. Don't recall where I said the T8 ran warmer than the Neu...in fact, the temp was lower. 123F, if I remember correctly. :)

I have one last test remaining for the T8...if she fails to perform, it's off to the chopping block for her.

You were right, I misread the temps. I still think part of the problem with the tekin motor, is its designed for a buggy, so less power available and less torque from the input

aaah....I see! So...the lower the KV, the higher the torque and the bigger the can.

So if I wanted a stupidly powered buggy, then I should use a truggy motor in my buggy, aye?

Well, well...we shall see. Looks like I might hafta sell the 2650 and pick up a lower KV T8.
