Alright. I've currently got a Summit with a lot of upgrades (MM2, DeWalt, Single Servo, Mudslinger, HR Servo Saver) and a completely stock E-Revo I bought second hand. Now here's my problem. I don't know whether to sell both cars and build something like an MT Slash 4x4 or an E-Slayer or sell the E-Revo and go brushless with the Summit or swap out all my good parts from the Summit onto the E-Revo and sell the Summit? What are you guys' opinions?
