The less turns is more revs and more speed
. I think I'll go for a 8.5 or something like that for the Stadium truck. With the 13T (3000KV) it can reach top speed almost instantly which is good, plenty of torque, it just doesn't seem to leave much on the table for when I have more skills that's all. I'll get a video of it over the weekend if I don't break it beforehand
. If you need to get a smaller esc do that and then practice your driving on your 13.5 turn for a while and see if you need more power then. But I think you will want a bigger pinion gear than the stock one
