RC8 temp problem
Hello all,
I have a problem that maybe someone can help with. I have an RC8 that was converted with the AE conversion kit. After I ran the RC8 for the first time (about 15 to 20 min of hard running in a big field) I came up with the following temps, motor 160F esc 105F but the fan was on? and the battery packs were 91F. This was with 15/46 gearing. The second time I changed the gearing to 16/46 and the motor temp went up to 190 degrees. So I pulled out the 16 tooth and replaced it with a 13 tooth pinion. I ran it today and the motor temp was over 200 degrees. This time I was on a tight local track so there was not to much in the way of WOT. I was running in a big feild for the first 2 runs. On the ESC, drag brake is turned off, timing is at lowest, I also beleive punch control is set to 40. as for the other info the RC8 has a V2 mamba monster esc, medusa 2200kv v2 afterburner w/rc monster heat sink, 2 2S 20C 5000 Orion pack, diffs 5,7,3 silicon fluid, 1ST(46/15), 2nd(46/16), 3rd(46/13) for gearing. Between the 2nd and 3rd run I took the entire car apart and cleaned, oiled, and greased every thing, so all moving parts on the drive train move freely and smooth. So what else can I do? What would you do. I have just about ran out of ideas. Please help if you can. |

you might want to just stick with the 15t pinion. i know on mine when i had the ae kit on it ran 140 with a 16t pinion and that was with a 2650kv cc motor and 4s 30c lipos. Right now i have the tekno kit on with the clutch and it runs at 130 with a 17t bell on it.
how long is the motor. also i did not even run a heat sink. |
