I'm not sure how much this tx can cut down but according to the parts list it's got a 23t pinion and a 64t spur. I'm guessing I would have to go with there brushless pinion of 13t to keep temps down as of now the brushed has seen 175 degrees on pavement with the 3800mah nimh and has not seen full pack of 2s 5200mah lipo. Do either of you know another brand of cvds that will fit this rig it has 87mm dog bones right now
