Kelly, I’m using the 2.85:1 (RD-1C). Static rpm is 6150, take-off is 6200+ rpm; don’t have a lot of cruise time but typically use 5200 - 5500 rpm … have not tested for maximum rpm, flat-out speed yet.

Jeff,

  On second thought what ratio gearbox are you using and what are typical static, cruise and

maximum rpm's that you are seeing with your installation ??.................

 

Thanks again,

Hi Kelly, I have the 4-blade HP Warp Drive, it is 74” diameter, set to 14 degrees or 58” pitch. I’m using it on my 13B powered Wag-Aero 2+2 which is a high wing tail-dragger, 110 mph airplane; I’m happy with the performance. The prop is easy to adjust for pitch and is quite a bit lighter than an aluminum 2-blade.

      Group,

          A little off subject but is anyone in the group currently flying a "Warp Drive" prop ??.......If so

what is your opinion ??.............I just bought this one for my dorment "CASSUTT" project (To be

Rotary powered of course)...............This is a 60" diameter, HI-PERF model bought for a RV-4 to

be powered by 160 hp , 0-320 Lycoming............Should be just right for a short legged CASSUTT

that is limited to about 60" prop diameter and powered by 160 hp+ Rotary...............Prop has never

been used..............I would not put one of these on a hard thumping 4 cylinder Lyc but believe that

it work well on one of our smooth/geared Rotarys.............All opinions valued pro or con !!.............

 

Brand spanking new!

 

 Thanks,
