|  How long should my run time be?
Im still getting the kinks worked out on my ax10 but I have a few questions. Im running a Novak 3S goat, 18.5 brushless, RC4WD dig, CC BEC and 2200 3S lipo. I seem to get maybe 20 min or less run time on this setup at crawling speed. Is this about right? I also notice, the esc gets quite hot as well as the motor ~ 140 deg by the time I turn it off and let it cool.I havent pushed it further to see how hot it will really get? Im running a tuber and the ESC has a fan on it. It seems as if it is getting hotter than it should. Im not used to this config. my other rig has a Novak rooster and 35T integy with 5000 mah 2S and it seems to stay cool and run for about an hour. Last edited by evlwevl; 06-07-2010 at 01:04 PM. |

Sounds like something is wrong. I'm running a Tekin brushed set up in my Honcho with a 2200 2s battery with a 35T motor and get about 1 1/2- 2 hrs of run time. Though I'm not running a dig but I don't think that should make a big difference. Plus my esc or motor doesn't get that hot.

Make sure you don't have any drag on the drivetrain...you should be getting close to an hour of runtime I would think...

You should be getting about 40-45 minutes from that pack. What are the cont. and burst C ratings of the battery your using ?

Check that pinion gear mesh. If it's fine, take the pinion gear off or back the motor off and give the drivetrain a spin. Won't spin forever, but it should spin freely. Try that.

Thats plenty of battery, sounds like there's some drag somewhere. Where's your drag brake set, when I tried to max mine with a 2s goat ESC and motor temps woukd get real high and I ended up setting the drag at 3 or 4 to keep the heat down.

i dont remember where I set the drag at, but i'll check that, the pinion backlash seems ok, theres a little gap between gears, 'ill check that again as well. it actually rolls more freely than my rooster/35t on my SCX10 which feels more notchy but that one runs cool, and quiet. I'm attributing that to the plastic gears and the higher pitch I'm assuming.

Well how much runtime do you get with that rig?
