Super Jet Metal Reduction Nozzle VS. Plastic one

[Patrick Star]

Quick question. Are there any performance difference from the plastic reduction nozzle and the 61X nozzle?

Just wondering.

Just the obvious that metal nozzles are stronger, flex less, and can be bored...

The plastic ones are fine. A metal one bored to 85 is much better for thrust.

i bored my plastic one to 85.5mm and it has finally given up the ghost. I am replacing it with a skat reduction nozzle which is a better design than the oem style.
