Has or does anyone run back cut props on there P-Spec Tunnels?

Thanks

I run an X442 that is back-cut and de-tongued. Cobra hull, Hyperformance bullet drive. UL-1 motor.

Did you notice any better performance with the back cut/detounged prop vs. a regular 442?

I run a back cut and cupped up 42x55 on my VS-1 with a bullet drive lower and UL-1 motor. Yes there was a performance difference, more speed with less current. It also handles better.

Just thought I would add this.

This past weekend I raced my P-Spec powered Vision 20 boat (running UL-1 motor and speedy). 42X55 Prop, slighly back cut. I was using around 2800mAh for .5 Laps before the start, 5 racing laps (1600m) then 1 more lap 'cool down'. Peak speed was around 73-75KPH (44MPH) measured using the Eagletree DataLogger GPS. average amps was around 50 with peaks around 105.

Kris,

I've run both the stock UL-1 and hydra 120 escs in this boat. It's a bit faster on the adjustable hydra.

What does that mean Mark? Are they good props for P-Spec also?

Kris,

I have a few new electric guys that like the way the H-5 and H-6 work

on their set ups.
