As it is yes, but if you read my earlier post i said "if all 4 gears meshed together" as a durability suggestion. If all 4 were to make contact, and the 1 gear (away from spur) on the short shaft were too move freely it would be a lot stronger and the 2 opposing centre shafts would spin and counter rotate the balance of the car.
