yeayea, I know one motor wire is coming off... :)
Upper deck is made from 6mm thick industrial (tough) plastic & aluminium, bolted to the chassis with three 4mm bolts going through aluminium pipe. This supports the frontend and offers good mounting point for steering servo, receiver, gyro, esc switch & fan.
Wire holes from Lehner were "siliconized" to prevent sand and dirt getting inside the motor.
