So there are two positions to mount the ESC and Receiver. The picture truck has it on the tray under the dash area but there is also a flat area to mount an esc on the rear bulkhead and the Fuel sell can be used at a receiver box. That being said, I was running a Tekin RX4 Mounted on the rear bulkhead with a Tekin Roc412 (Can't remember the KV, i'm at home typing this and my rig is at work). Geared with a 13T pinion. The spur gear is not interchangeable. It was running on 3S for that video shoot.

Two positions for the ESC and receiver are another awesome feature!
Is a pinion included in the kit?
