Kyosho ST-RR conversion

[George16]

Just installed some upgrade parts.







Dace Mfg. 17mm hex:


I had a chance to ran it last Friday and Sunday when the air temp was about 57*F and 68*F respectively and wasn't pleased with the results.

Here's my gearing and temps:

ST-RR
50/15, 5S

Air temp was 57*F
ESC – 104
Motor – 131
Batteries – 100

ST-RR
50/16, 5S

Air temp was 68*F
ESC – 112
Motor – 170
Batteries – 104

I'm going to try 48/16 this weekend and see if the motor temp drops. Both were continuous 10-12 minute runs.

I went up to 16T pinion based on this:
Hot motor, cool controller, cool batteries = undergeared
