I wanted to jump on this bandwagon too. I have seen all the threads about this conversion and wanted to build one myself. I have a Slayer 3.3 (not Slayer Pro). I love the truck, but my 3.3 is getting worn out and since I have already done one rebuild. The motor is done for. So here is where my E-Slayer will come to life.
I started with a Summit Chassis.
Then I decided I didn't want a grey E-slayer so I got the black dye out and done this.
