hello,

I recently bought a new controller, a DS 35 ohm, which gets hot over time. I had never actually noticed it with my old controllers, but I was wondering if this is normal and if so, why?

I'd like to hear it,

Probably depends what motors you are using it with and how much time you spend on full throttle. If you go slow, you are using the resistors in the controller to reduce the current to the motor. Rather like an electric fire, putting current through a coil (resistor) makes heat. At full throttle you effectively bypass the resistor.

I use an MRRC 5ohm controller with hot rewinds and have to hope the heat is only 3 to 5 minutes. I've had blisters on my hand before now. I use a thumb controller so the resistor is vertically about 1mm from my palm. At least the DS resister is at the top.

You might consider a transistor controller if the heat bothers you - more money of course!

ah thanks for the answer, I was wondering if it could do a lot of harm before I destroy my new controllers  ahaha

If you are running standard cars like Scalex, Ninco or Carrera, you shouldn't have to worry. There is a difference between quite warm and hot. 
Smoke and flames probably mean it's too hot.

they are mainly FLY cars, and some Ninco models,

luckily no flames or smoke seen yet ;)

Standard answer to nearly all problems is therefore......drive faster.

If it's a v2 or v3 version, then you can relax...from the Pendle site: -

"Like the previous v2 version, it incorporates a self-disconnection system due to overheating or track crossings to avoid burning the controller."
