4s in a TC3

[SpEEdyBL]

I find it surprising that the the Tekin redline motors are often overlooked. I'm in the midsts of testing my tekin 632 3200kv motor on 4s with the MM in a xxx4. The design of the tekin motors is very similar to that of the Castle motors (rotor size, coreless design, can dimensions) but unlike the castle motors, they are rebuildable and have solder tabs.

So far i've tried 19 and 23 tooth pinion gears, which translate into theoretical speeds of 46 and 54 mph. The battery I am using is a Neuenergy 4s 4100 mah 30C pack - the same battery that I use in my 8ight conversion, in other words, overkill. RTR weight is just under 4 lbs.

With the 19 tooth after 5 minutes of running up and down the street:

Motor: 180F
ESC: 125
Battery: 85

It felt as if the motor topped out very quickly. Motor temps were very surprising high.

With a 23 tooth pinion gear after 5 min;
Motor: 185F
Esc: 130
Battery: 90

Again motor temps were very high. Top end did not seem that much greater, but it was hard to tell since the motor doesn't make any revving sound, and neither does the xxx4 belt.

I'm going to try a 17 tooth pinion gear before increasing the timing from 0 degrees to 10 degrees to see if that improves motor temps. I'm guessing the tekin motors are 4 pole motors since 6 turns seems a bit low for 3200 kv don't you think?
