I know the ones made by someone else were not as tall, but from what's been posted, other than engine placement these gear boxes appear no different than the earlier HL ones. Since the hull shouldn't be different, nor the back of the upper hull from the PIII, not sure why they would have changed them at all.
The "low profile" boxes built by whoever I believe were made to accomodate the airsoft.
I aked Bill that same question and he said that the top Hull sits lower then the P-III so they had to lower the motor, and yes they just added a bracket so you can service it and moved the pinion point, same gear ratio!
