Problem with getting hott

Overloading the esc. Motor wanting more amps than the esc can provide. How hot is hot? Anything above 140F on the esc is too hot to me.

I thought you had installed Trenchers and have a 4000kv motor. How hot is the motor getting? Did you gear down any? How hot was the motor and esc getting with stock tires?

If the motor is running below 160F and the esc is getting above 140F get a higher amp esc.
 
It was getting hott with the stock motor and ESC actually the ESC that came with the 4000kv motor just quit working I think it got too hott and fried and no I haven't put a different gear in it what should I put in it... I forgot that will cause it to get hott.. it has the stock gear in it as well.. what gear should I go to
 
First things first get a IR thermometer and keep a eye on temps when changing anything (tires, 3s, different motors etc.) this is the one I use https://www.harborfreight.com/non-contact-pocket-thermometer-93983.html. Gear for the conditions you run in and the battteries you choose to use (2s, 3s). I have a guideline of keeping temps around 160F or less on the motor and try to keep no more than 140F on the esc. If the motors running hot gear down. If the esc is getting hot but the motor is not get a bigger esc (higher amp). Some escs will go into thermal shutdown when they get to hot but some will fry instead. Don't get a esc without a fan yes if the fan fails a esc can still burn up but I would rather have one then without one. As for gearing I usually go in increments of two so if you have a 19t pinion go with a 17t. If you go as low as you can on the pinion and the motor still gets hot go with a lower kv motor or larger can one like a 3660 motor. For the Ruckus for its size and large tires I would get a 3660 can motor. Again this depends if you run in grass use 3s lipos and so on.

I do run 3s lipos and 2s I have a 4000kv motor and it really wasn't haven't this problem till.i changed the motor so I may need to get a higher amp ESC and gear it down
 
Will this work on my ruckus monster truck

Got a 80a Goolrc esc its basically the same in my circuit now running a 3660 motor on 3s but it can get hot I would spend a few dollars more and get the 120a esc. Got the same Ocday 80a esc in a Rustler running a 3650 4370kv (full size can) motor on 3s does ok. High kv motors pull a lot of amps on 3s and having a larger than needed esc does not hurt one bit. Look at the specs of the motor you choose and choose a esc that can provide those amps that the motor can draw.

You got a few threads going I would try to keep questions in just one or two of them so people can keep track of what you have in your Ruckus and things you have already tried or done.

Go down in gearing if things are getting to hot. If you have a 25t now drop down to a 19t if your running 3s. Even with a 3660 4300kv motor in my Circuit with a 22t pinion, big tires on 3s temps can start to get hot. Gearing is based on temps so gear you motor to keep temps under control. 48p pinions are cheap so get a few from 17t -22t and experiment not everybody has the same rig or run there rig the same so you yourself will have to figure out what works best for you.
 
Is gearing it down going to make it slower

Yes
Or more torque on start and lower top speed

Yes you got it. Think of it as gears on a bike the closer you get to 1:1 ratio the harder it is to pedal but the greater the distance you travel with each single rotation of the wheel. Its harder getting started but you don't top out spinning as fast as you would on a smaller gear.

I may have got that mixed up but I think you get the idea.

Okay thanks I will experiment with it gearing it down don't think going up is going to help but I could be wrong just going to experiment with it and find out and I will let you know
 
I have a new prolline Ford raptor body that I'm gonna paint and put on it too think I got it in the mail today I'm excited just not sure what color I want to paint it yet
