Hey everyone. I just got into the hobby and I'm having a blast with it. I have a 2wd Slash VXL that I ran with a 9.6 5000 mah nimh with 23/86 gearing. I don't have a heat gun yet but after the first run the motor was too hot to touch. I dropped the gearing to 19/86 and that seemed to help a little but the lack of top speed was evident. I was wondering if you guys think that an 8.4 battery with the 23/86 gearing would give me a little more top speed than the 19/86 with a 9.6 but without the heat issues. I was a little surprised I had the heat problem with the 9.6 battery. I run on pavement and do two block runs. Any thoughts or suggestions would be appreciated. I also have a Rustler VXL with the stock gear ratio and stock battery and haven't had any heat issues with it doing the same runs and a little off-road.
