leedsrhinos126 Posted November 12, 2014 Share Posted November 12, 2014 As title slash 2wd has a brushless leopard 9 turn motor with 19 pinion and 84 tooth spur gear. The motor wires including the motor keep getting very hot and melting the wires motor is also fitted with a fan. The same motor and esc have been used previously on a tb02 drift car with no issues with getting hot. Any ideas? Thanks Quote Link to comment Share on other sites More sharing options...
Tug Posted November 12, 2014 Share Posted November 12, 2014 Drop the gearing? What voltage are you using? Quote Link to comment Share on other sites More sharing options...
b19jas Posted November 12, 2014 Share Posted November 12, 2014 That motor is too weak for the slash. I am gonna guess its the gold coloured finned can? 1 Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted November 12, 2014 Share Posted November 12, 2014 It'll be the same as the old EZRun 9T ... a 380 motor in a 540 can. Gear it right, and it should be OK (ish) . Ran one in the lads Stampede and it was OK. Did get a bit warm, but the only time I melted wires was when I used an adapter cable on the battery, and the wires on it were a bit too thin. It was only really meant for charging Geared right, it will cope with 2S. Quote Link to comment Share on other sites More sharing options...
RCbutcher Posted November 12, 2014 Share Posted November 12, 2014 I wouldnt use that motor it fools quite afew people into thinking its a 540 when buying. But really its a mini e-revo type motor. Ide get a vxl motor but prefer a flux vector 4000kv or hobbywing 4000-4600kv in fact the 4600kv might be better. Then put 32dp gears on the truck. Is it a brushless ready model with all metal gears?

bertberr Posted November 14, 2014 Share Posted November 14, 2014 I suppose it depends on what battery you're running too. If 3s I'd limit the motor to say 3800/4000kv max, probably a little less. 4 pole would be good too in a heavy(ish) truck like the Slash.

Tear101 Posted November 14, 2014 Share Posted November 14, 2014 I run a 10T etronix( same as leopard) in my slash on 2s lipo and have had no issues with heat. Can't remember what my gearing is but could look later if you like! I'm going to step up to full 540 motor this winter as the etronix does a great job but know it could be faster with a 540 in it.

leedsrhinos126 Posted November 14, 2014 Author Share Posted November 14, 2014 Thanks for the reply's What gearing should this be running? I have a Team Associated SC10 2wd with similar problems running a Ezrun 9t motor. I've burnt out 2 of these motors using 87 spur and 21 pinion. The motor gets incredibly hot using 2s lipo what gearing should this have to keep cool and to be able to use it more than 5 mins? Quote Link to comment Share on other sites More sharing options...
Tear101 Posted November 14, 2014 Share Posted November 14, 2014 I think mine is 19 pinion and 90somthing spur. Quote Link to comment Share on other sites More sharing options...
leedsrhinos126 Posted November 14, 2014 Author Share Posted November 14, 2014 When people say gear down does that me more teeth on the spur and pinion or less teeth. I'm new to brushless, 1/5 petrol is so much simpler Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted November 15, 2014 Share Posted November 15, 2014 Lower gearing means more teeth on the spur OR less teeth on the pinion .... or both! Quote Link to comment Share on other sites More sharing options...
