http://www.hobbypartz.com/ez-60a-rc-...ar-system.html, thats the only thing im seeing that is in stock for the hobbywing. you could get the 35a esc and a 380 size tacon but be nearly as much power and speed. the system i just linked is a 6000kv which is kind of high but the 4000kv system is also out of stock. so does anybody else think that the 6000kv would be okay in a rustler because everything else is out of stock. you could also get a sidewinder but it is a little more money.

if i were you i would just spend the extra $20 on the sidewinder.
