Ok, Taigen metal roadwheel/swingarms and Banebot 380`s ordered. If the new motors do not improve performance, I have a hard decision to make. I love how the 4:1's allow the Leopard to spin with ease in grass and carpet, turn anywhere and travel at a consistent speed no matter the terrain or incline. Especially the ability to do all of of these actions at a crawl. Unfortunately the top end is just a bit too slow.

I`ve been playing with the ztz-99 with speed 400's on stock steel mato boxes, PIII on stock steels with stock motor and Panther on Asiatam brass boxes. The Asiatam setup wins hands down for balance between speed and power, but even these take away the low speed control that I've come to appreciate with the 4:1's. I really wish there was a magic bullet solution to get both ends of the performance spectrum, but I'm guessing the rx18 limiting me to a 400 motor is the real culprit here.
