jim46 Posted July 4, 2016 Share Posted July 4, 2016 Hi all, just started to get into racing with 1/8th scale buggy, outdoor astro, got 2200kv torro x8 motor, and 120 amp hobbywing esc, I know the esc probably was not the best choice here but motor seams good, olny issue is motor gets hot after about 10/15 mins running time, its in xray xb8e running standard gearing from stock set up, should i go down a bit with pinion size to help here, running at ndor off road, Quote Link to comment Share on other sites More sharing options...
dazp1976 Posted July 4, 2016 Share Posted July 4, 2016 You taken any temp readings with a temp gun? Worth getting one. Touch alone can be deceiving. Safely I'd go a maximum of 70 degrees Celsius. If motor hot then yes drop a pinion tooth size or 2. Grassy surfaces even astro cause friction. The higher the friction the harder it is on the motor, the easier you need to make it ie: lower pinion = less stress. I'm not really rating these brushless systems when it comes to surfaces like this All the torque they use to get the vehicle moving is where the heat is mostly generated. 1 Quote Link to comment Share on other sites More sharing options...
