Gordon, I still have my Felix Bi-Cambered 68X71. It
turns 2200 static on my 150 0320. Full throttle at
3000 is 2650 and 180 mph. I think it would work much
better on a 160 0320. I've reduced the price to $600,
Felix gets $950 for this prop. If you would like to
try it out, I'd be will to ship it to you for cost.
Take a week and fly it. Let me know if your
interested. I'll be in the shop this morning if you
want to talk about it.

Gordon, Sounds a little high for static and only turning less than 2800. Do you
have wheel pants and gear fairings on? MPH or knots? Should be stamped on the
side of the prop hub what it is. The 68-74 is just a ball park figure, performance
may vary between prop makers and even between props made by the same person.

Jim , sounds good. I had 9168Q out this evening for the first time since
the new heaver gear and mount and new dimensions. Works great. and evidently
my welding is holding ok. I think I could use more prop-- I get over 2500 static
and flat out at 2000 can turn almost 2800., and showing almost 185 indicated.
It's a felix 69-69.
If I remember-- do you still recommend a 68-74 with this 0320,160 ? Thanks
Gordon

Jim:
Last year I helped Bill Cardoza install a single axis Tru Track autopilot in
his (hopped up) Thorp. He likes it very well. Works well with his handheld
Lorance 300 GPS. He does not have the pitch control, but is thinking about
upgrading to it. Was easy to install and wire up.
For myself, maybe in a few years, but for now, I still like flying the
plane. It probably could be a lifesaver if one ever got into clouds though.

That makes sense, you will pick up about 15 mph with pants and fairings. Your rpm
will also go up about 200 rpm. If you order a new prop, go with a 68/74. That
should get you in the 2300 static and 2750 range. You other prop will make
a good spare or could be tuned up to get the rpm down some. Get the fairings on,
it makes a lot of difference. Jim C

Dave, It is connected to the Garmin 430 with just 3 wires. Bob ordered it
with a prebuilt harness that connects the servos to the dash mounted
controller, that makes things much easier. It needs about 7" behind the
panel to fit in, we had about 6 3/4" so things got pretty tight. Mounting
the servos wasn't a big problem, I made a aluminum angle platform that
fastened to the 3/4" diagonal tube and the lower truss tube under the
baggage floor. The aileron servo connects to the left bellcrank and the
pitch servo to the long elevator 3/4" tube. If you want to spend some money,
this is the unit to get.

Jim,
How do the servos attach to the bellcrank and to the elevator tube from the
standpoint of disengaging the servo? Is the de-coupling handled by some type
of electrically activated "clutch" or similar device within each servo? If the
disengagement mechanism failed to release can the servo be manually
overpowered?

Jim,
Do you have any flight measurements that show whether it's the gear leg
fairings or the wheel pants that provide the majority of the speed gain, and what
are the percentage numbers for each? I think I once saw something on this but
can't find it now.

You can over ride the servos without disengaging but you can still tell it
is trying to do something. A disengage switch is mounted on the stick.The
servo arms are connected to the aileron bellcrank and elevator tube with
3/8" aluminum rod with heim type rod ends. I drilled a 3/8" hole thru the
aileron bellcrank and welded in a bushing for a 3/16" bolt. On the elevator
tube I made a 1" long clamp from 7/8X.058" tubing and one of the two clamp
bolts is used to fasten the rod end. With the auto pilot off you can't tell
it is there. Jim C

Seems you get a little more from the gear leg fairings.
