MM temps in Traxxas Slash

[Just go Play]

I didn't see it mentioned anywhere but what do you have the motor timing set at? If it is not at the lowest setting give that a try.

If you do end up cooking the motor you may want to try the velineon motor with your 3s lipos. You should be able to gear up to get more then enough speed to smoke the neighborhood revos with that setup.

I have the timing at the lowest setting.

fwiw I program my MM by holding full throttle before switching it on, never had a problem.

It seems strange that you dont get arming tones - they play through the motor, so it wouldnt have anything to do with caps.

That's what the manual said also. Maybe mine has issues?

Yeah, it cant be that much different than setting it up in a rustler. I'd disable your punch control, double check your timing is disabled or set to lowest, and set your start power to high. I'm sure the 5700 is fine on it, maybe cut a hole in your body to get some airflow to the esc. Really you shouldn't have to gear that low. Maybe if you're running it through grass, but on hard dirt or pavement 17 or 18 should be more than low enough you'd think. I personally don't have a slash so I can't say. But it seems to me that the drivetrain is the same as a rustler and the weight shouldn't be more than a pound or two difference, there is no way a 5700 is not motor enough to push that around at a higher gear. Especially if the exalted titan wasn't overheating at stock gearing. Play with the castle link software settings, make sure you have the most recent firmware release and maybe borrow a 2s lipo from someone and see if you can nail this thing. Also mounting your esc behind your rx box probably isn't a good place for it, should keep those two as far apart as you can. Also check motor plugs, if there is any corrosion looking spots on any of them, clip them off and direct solder.

I just thought of the whole arming tone thing. If one of your motor plugs aren't making good contact, ie unplugged or crispy plug, it won't sing to you I've noticed.

I ran today for a short time and things seemed better. Perhaps this is all "user error" on my behalf. I'd hate to think I'm that stupid. I geared it back up and temps seemed better. I have no reasonable answer for this.

The arming tones are definetly funny though. Sometimes I get them, sometimes I don't.

[Sammus]

They often change volume and sound depending on the car, or if you have the wheels on the ground or if your touching the motor (absorbing vibrations).

In my CRT they sound really funny, I think because its all alloy on alloy with a metal pinion/spur, it sounds like its all fuzzy haha. But yeah sometimes ive noticed they go really quiet too. kinda cool how it plays you tones like that i reckon :P

Well, like I mentioned, check the motor wires. When mine was giving me problems, it would act real funny like, not arming but still working or it would arm then it would run, then stop, jiggle wires or kick it, then it would run again, I had a seized up bullet connector on the white wire, the part that spins didnt spin and had black spots all over it. I chopped it, soldered it direct, worked better than ever. Then my car eventually started glitching real bad, chopped the other two off, the black one this time was seized, now it works like a champ.Or it could be a funky ESC.

If you sometimes get arming tones, and sometimes don't and you're running really hot sometimes and sometimes not.....you have a wiring problem, definitely. Pull on all of your bullet connectors to make sure the solder joints are still tight. Make sure all the connections are fully seated and clean. 1maxdude mentioned he saw black spots, definitely a sign of arcing. If you see any of the above, that's the source of your problem

Arming tones are all normal now. I've upgraded my batteries.
