When are you planning on bringing these parts to sell? I'm really excited to see all that you've done! Your upgrades look phenomenal! It looks like your transmission and motor combination will have plenty of power to do anything that you'll ever wanna.
do you have any ideas on what esc and mixer you will use to connect to an RC receiver yet? Place turret controls on one stick and track controls on the other I would imagine. Then wiring in a sound system to give Sherman engine sounds.
