Nozzle size

[Foximus]

I ran 82mm on my metal 750 nozzle and it was great improvement. When I got the X2 nozzle with the guide veins, it was at 83mm and I couldn't tell a lick of difference between the two.

Yes, but what is to big? With the smaller volume and higher pressures (especially with the TBM mag hub) it operates like a mixed flow, and not a axial flow pump. So going too big is much easier than the 144.
