WARP DRIVE: Square or Taper Tip

[Norm]

Is it a two blade or three blade warp.

[JimS]

It's a CHREE Blade. (FAA controller talk) 3 blade for the rest of us.

Thanks for reply. I have a two blade that has much better performance than my IVO but with a nasty vibration I won't live with, I have considered sending it back to have it tapered.

Shipped my square tip Warp Drive to Iowa to have it cut to Tapper Tip and install nickel leading edges. Looks like I'm grounded for about 3 weeks.

Sorry to hear that Steve. If I had a spare Ivo, I'd send it to you or better yet, come down and fly with me.

[SkySteve]

Thanks, DF4. Both sound like great options.

Received by newly cut Warp Drive Taper Tip propeller yesterday. Installed it today. I set it at the same pitch as before I had it cut and did a run up. I gained 300 RPM Wide Open Throttle. The weather was crappy and time was short so I didn't test it yet. Within the next few days I'll do some take offs and cruise testing and let you know how it goes. So far, it does exactly what Daryl at Warp Drive said it would do.

Steve,
What pitch are you running and what engine?

Thanks Eddie

The engine question is easier than than pitch. The engine is a Rotax 912A. 80 HP. The pitch is 11 degrees at the tip. I checked it at the inside edge of the nickel leading edge, closest to the attach point and it is 22 degrees there. I hear all kinds of pitch degrees and have never really understood at which point people are setting pitch. My plane is 660# empty and I have 8.00x6.00 tires. Before the tapper tip I could get off the ground, on pavement, with just me and full fuel in an easy 300 ft. It would cruise at 100 mph but preferred 90-95 mph. My Wide Open Throttle during run up was 4,800 rpm. Now it's 5,100+. If I can get a nice cruise at 95-98 mph I will take a little pitch out for shorter take off.

I think you should be able to get that. I have mine set at 11.5 deg at the tip. My model 4 is a long wing taildragger has 26" bush wheels, and I see 105 at 5200rpm 96-98 at 4800.
