I'm trying to decide between the RTR version of this popular RC crawler and the new assembly kit. The kit comes without a few necessities, so I am trying to work out the best value when comparing the RTR, the kit with the same components as the RTR, and the kit with some popular components that are budget friendly upgrades from the RTR version. Required extras are transmitter & receiver, ESC, motor.
