Which MTroniks won't fit? I thought most 540-sized motors, brushed, or brushless, should be roughly the same size? If I were to buy a brushless for the D4,what should I pay attention to (size wise)

Brushless generally are all the same length as brushed motors - but where a brushed motor generally is narrower at the rear, where the brushes and end bell are, some brushless are different.
The Mamba MAX for instance is square at the rear - so it is maximum diameter all the way to the back - but this motor is shorter than some, so it will just fit. The LRP motors are beveled at the rear so will fit even though they are longer than the motor area cut into the main chassis. The Mtroniks motors are same length as the LRP motors but same diameter all down the length like the Mamba motors and so foul on the chassis (the rear of the motor sits up on the chassis).

It's probably not a big problem for most cars, but the D4 could have used a longer motor cut out is all.

Thank you Jimmy for the explanation!
D4 still out of stock in HK! Can't wait to get my hands on one...

Not York I'm afraid Andy, you'll have to be at Southport, Bury or Oswestry if you want to see it run this year ;)
