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. ===== BRIAN ALLEY (N320WT) CARBON FIBER COMPOSITES 304-872-7938 shop 304-562-6800 home How are you going to win by a nose if you don't stick out your neck? ________________________________ Message 2 _____________________________________ Time: 05:22:34 AM PST US From: "Jim and Donna Clement" <168x@merr.com> Subject: Re: Tailwind-List: Autopilot 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.

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 ________________________________ Message 3 _____________________________________ Time: 07:18:14 AM PST US From: "DaveM" Subject: Re: Tailwind-List: Autopilot --> Tailwind-List message posted by: "DaveM" 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 figure was without wheel or gear fairings Gordon ________________________________ Message 5 _____________________________________ Time: 10:30:13 AM PST US From: "Jim and Donna Clement" <168x@merr.com> Subject: Re: Tailwind-List: Autopilot 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.

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.

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?

I think I once saw something on this but can't find it now. In a message dated 5/20/04 1:31:06 PM Eastern Daylight Time, 168x@merr.com writes: > Get the fairings on, it makes a lot of difference.

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.
