Theyve really thought about this, I was curious as just by turning the gearbox the motor rotation would be wrong - like the early 3 gear X-6. But Losi state it has 3 gear gearbox for rear-motor and 4 gear gearbox for when mid-motor, so this is optimized for both configurations - all parts included in the kit too.... I hope im reading it right, but if so, great work TL!!
