While at Sun & Fun I stopped by to
take a look at the new Sensenich ground adjustable prop. They had the hub
and prop blade stubs. The prop blades shown in the display were hollow
without any core, not certain but the skin of the blade near the hub looked to
be approx 1/8 – 3/16 “ thick – seemed a bit on the thin side,
but then also appeared to be perhaps carbon fiber. I guess they could
have a core that was just not present in the exhibit blades.
The hub had six bolts with a “pitch
block” which is inserted in the front of the hub to lock the blades to
the correct pitch. Certainly looked interesting – however, the
largest pitch they had listed was 60”. I asked if they were going
to produce blades with greater pitch and the representative told me –
they could if necessary.
So you might want to check if looking for
an adjustable pitch prop.

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.

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 !!.............
