So far, no problems but it does look a bit scary. Thicker packs like today's 4800mah and 5000mah packs are out of the question unless you don't mind having the battery on the outside of the bulkhead (moving weight away from the centre, sacrificing one of the advantages of the stock layout).

Before the photos were released, many people were expecting weight to be moved forward. The 416 has the motor, spur, and centre shaft, shaft bearings and bearing holders moved a bit to the rear. Tamiya claims this is done for traction. I don't know about that but I do know it clears up some room for the battery. Also, this clears up a bit of space on the electronics side so you can fit a chunky ESC in easier.

Also bear in mind that this car will be here almost the same time as the TRF415 MSXX MRE. Which one will TRF drivers be running in big non-LiPo races? Which one will dominate if battery rules change? We shall see.
MaxAmps 5000 packs fit under the bulkhead with no mods.
