I’ve watched a surprising number of those vids. They’re a great source of information about things that works and things that don’t. Didn’t see anything in there about cooling, however. I hadn’t seen the o e about the shock tower braces. Those are in my future.
Unfortunately, I did t see anything that will help me gear up a few teeth and keep my motor from releasing its factory installed smoke. I’m hitting anywhere from 120° to 160°: depending on race conditions and duration. Motor timing is setfairly conservatively to about a 6 amp draw with no load. (pinion off)
thanks for the tips, in any case. ��

For gearing, set it so that you hit max speed about 3/4 of the way down the front straight. If you get the right timing and gearing your motor should run pretty cool.
To get more speed, I'd ditch the stock slipper and put in the STRC topshaft with an AE or Avid/Schelle slipper. Maybe even a slipper eliminator. That will drop a ton of rotating mass off the drivetrain. Also clean the grease out of your bearings and oil them instead. That will reduce the drag. I'm assuming you're limited to 13.5t motors? You probably want a torque rotor in that motor rather than an RPM rotor.
Basically I think that trying to cool an over-stressed motor is the wrong way to go about it, and would look for ways to make the truck more efficient so that the motor is working at optimal gearing/timing/heat.

I suppose, as far as motor timing goes, I’m approaching this from an on-road perspective. The general theory I and many others follow is set the motor to its sweet spot, which very oddly, is around 6 amps in a lot of motors. After that, run it, check temps and gear for maximum speed. From our conversation here, I’m going to take away two things. First, the timing and temp thing does cross over from on to off road and secondly, I should consider investing in a basic motor analyzer, rather than relying on my ammeter/load tester.
Thanks for mentioning the topshaft/slipper conversion. I’d forgotten about that one. The Associated slipper is definitely lighter and more flexible than the stock 3 puck unit. I’d love to run an eliminator, but my throttle control isn’t quite there and I’d be stripping gears every run.
You’re dead on about our motor limit. When I picked up my Slash a few months ago, it was converted to a basher buggy and had the Velineon system in it. SO torquey, but just a little outside the rules. I’ve been replacing parts a few at a time to turn it into a good racing Slash. It came with the LCG conversion, so i got into the game with a decent truck.
Thanks again. I appreciate your and everyone who else’s input.

I'm running a 3900kv motor in my slash geared 86/19 at my local track. This motor is probably similar power-wise 2 what you're running. My motor never gets above 140 degrees in 93 degree, 100% humidity type weather. Like razor said, by the time I'm three-quarters of the way down a 140 foot straight away I'm pulling Full Throttle letting off to get on the brakes to make a 90-degree left hand turn.
Gearing is the key to keeping your motor cool.

I think you got it, I haven't bought a motor analyzer yet, but I think you can get enough info from the manufacturer, the forums, and a feel from the temp readings to figure out a good timing setting.
Good luck with the truck!

Shock upgrade
Hi guys
im thinking about upgrading my shocks on my 2wd slash. Obviously, I looked Prolines, traxxas GTRs, team associated SC10, Losi scte and etc... those on the SCTE looks really nice. I have an eye on them.
Do you have guys, some pictures for me of your upgraded shocks?
Other question: I read a previous post (written by RazorRC) and i was wondering with the STRC transmission top shaft and the AE slipper if I could run 32p gears ? I was not planning to change whole slipper but I was thinking about to run 32p gears.
thanks, sorry for mistakes, im from Québec !

I'm not sure about the 32p gears. I'm sure someone will chime in here shortly.

In my slash where I had a lot of power going through the transmission, I opted for the STRC AE topshaft, AE slipper pads, slipper hubs, spring, and nut, with a robinson racing steel spur. Add on a 32p pinion according to the motor you're running, and you're set. Plastic spurs could work with lower powered trucks but for a basher I like having the peace of mind that my gears will never strip or melt/warp.
