I installed the gearbox this morning and I am sad to announce that it failed horribly. After 300 rnds I noticed it started to sound funny and the fps was dropping significantly. tI opened the gearbox and found that the polycarb piston head shattered into a dozen pieces which in turn destroyed the cylinder head. Upon further inspection, I noticed the switch assembly was very flimsy and was beginning to burn up and melt.

My boss bought the front wiring version of this gearbox and had the same experience.

We are both using 11.1v lipos with 20c discharge. As for this box being lipo ready, I would recommend buying a different box.

On the plus side. I do like the stronger design of the case and the ballbearings, but until Matrix fixes the weak internals I wouldn't recommend this to anyone.
