how can i make my esc run cooler
 

how to keep the esc cool

emaxx 3905

feigao 7xl

100a ebay esc http://cgi.ebay.co.uk/67G-Programmab...742.m153.l1262

stock emaxx spur what is the stock spur is it 64t or 68t and 22t pinyon

ive got a ubec and a fan

i have also taken the heat shrink off the esc

Add an extra cap - try to reduce gearing - change the motor - buy a better esc

Or you could put it in the fridge and that will for sure keep it cool.
No what Arct1k said - there are many things you can do to keep an ESC cool just need to know what other variables there are.

run a higher turn motor and that ESC can handle a 5s pack...high voltage + low KV = cooler system but Feigaos will run on the hotside it the way they are designed. Good thing they are cheap and make sure your ESC timing is set at 0. You can try a Medusa motor they are better than a Feigao but not as good as a Neu.

5s with 10XL should be a decent system

Motor timing is normally for motor temp rather than esc temp...

I'm guess given choice of brushless components that this is a budget setup - the 7XL is probably the main problem - It's an Amp intensive "relatively" ineffecient motor... result - Hot esc and hot motor

I thought it was for the motor.....sorry...:tongue:

wil a spur with moor or less teeth cool it down al so could some one tell me what this things mean in the manual AdvanceT (Timing): low, middle and high, default is middle and Freq=(PWM frequency)

thank you

I would go less (18) and try low timing to see if that helps with motor temp

the motor is ok but wil that cool the esc new to brushless but not rc

thank you

I think timing is motor but pinion should help both...

could i change the spur

no bigger spur - same effect

thank you all for the help

a smaller spur is gearing up and that will increase resistance against the motor/ESC causing heat

Sorry i need sleep!
