Hey Paul,I'm sure that something could be designed to work with a little thought. I havebeen thinking about your question for several hours and I am not sure why youwould even want or need one in the front cockpit. Piets are soloed from therear seat, that being said, if someone were flying it in the front seat thenI would only hope that there is a qualified pilot in the back seat to adjust thetrim. The second thing that comes to mind is that we as builders should beconcerned about any extra weight we build into the planes. It only takes awayfrom our useful load no matter how minor the weight gain. All that said, I'm sure someone on the list with a similar trim system would havesome useful ideas for the front hole. My trim system is not like any otherPiet I have seen. It is copied from a pre-war T-craft. It could be made towork from both cockpits without a lot of extra work.

Are you putting in airspeed indication in the front too? If not, don't reallyrecommend trim, especially for front seat instruction. That way, fifty alwaysfeels like fifty, sixty always feels like sixty, etc. I taught my son to fly in the front of a Piet. Good intercom is way more important.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Piet on Barnstormers posted Oct 12

Folks; I'm not trying to shoot down anyone's favorite trim actuation setup, justpassing along another data point for consideration. On the way to the CopperstateFly-In this past weekend, a friend's Super Cub with a Bowden-cable actuatedtrim tab on the elevator had the cable break at the trim tab. The tab immediatelywent into a violent flutter and acted as a servo tab, which set theelevator into flutter sympathetically. My friend said that he thought the enginehad blown or that he had lost a prop blade, the vibration was so violent.Changes in airspeed and power setting didn't change anything so he realizedthat it wasn't the engine. His passenger had the presence of mind to suggestthat he lower the flaps, and that seemed to blank some of the airflow over thetail and diminish the frequency of the flutter enough to where they limped about30 miles to an airport.Upon inspection, the Bowden cable was found to have a brittle fracture betweenthe point where it emerged from the outer sheath and the point where it attachedto the tab, and the wire was extremely work-hardened. This airplane is a completerestoration with less than 300 hours on it, and my friend is an A&P. He's replacing the Bowden cable setup with an electric trim servo.Just passing along this information, and I see that the way the "Big Piet" guyshave theirs set up, the amount of wire outside the sheath is about as short asit can be while still providing effective trim tab travel.

The trim tab on the Lark glider our club used to own, and also the one on our towplane are both moved via double bowden cables, one top and one bottom so that most of the actuating is done in tension. That arrangement also provides redundancy in case one cable breaks. =0A=0A=0AMatt Paxton=0A=0A=0A=0A

Some more general ponderings about trim and a question.For most of the around-the-patch flying I do, in level "cruise" flight, I "trim"with the throttle. If the nose is dipping, I bump up maybe 50 rpm (usually less).If I detect a slight climb, I pull the throttle back just a little. Thedifference in airspeed is usually less than 5 mph. I don't really need a trimmechanism for this.Where I would like trim is on climb-out, where I need to push forward on the stickif the fuselage tank is less than 3/4 full and there is no passenger, andon base and final, when I've pulled power back to idle and I need to pull thestick back quite a bit to keep the nose up and maintain 50-55 mph.For all those who have a trim system on their Piets (Scott, Barry, Gary, and others),does your trim system work with enough power to, say, maintain a steadyairspeed while on final?

This is when I need the trim the most.Your question regarding trimming during landing is a definite no. I tend tonot make approaches in a straight line. I will usually be in a turning slipto final much like you see people do in a Pitts or other Biplanes. I don't evennotice the stick forces during landing. Oh, It's nice to have during climbout too.

I know this is a little off post, but this is a flight simulator our EAA Chapter just finished. This pic is in my shop and was before the decals were applied. We used Sherwin Williams latex primer and finish paint. We also used a short knap roller so we could get a flat =9Cmilitary=9D look. Found that if you =9Cgo over=9D the wet paint a second time, it creates a very flat look. See the windshield in the picture, it has a fuzzy look, but for our application, that=99s great. So apply one coat and let it get dry before applying another one if you want a glossy finish.This was our first attempt at latex, but after it turned out so good, I don=99t think it will be our last.BarryNX973BP
I know this is a little off post, but this is a flight simulator our EAA Chapter just finished. This pic is in my shop and was before the decals were applied. We used Sherwin Williams latex primer and finish paint. We also used a short knap roller so we could get a flat =9Cmilitary=9D look.

Jeff;This is a very interesting development. By all means, keep fiddling with it tosee if it can be made handier to use. I know I would be interested in it, because(for example) when I fly with the tank topped off (16 gallons in the nose),I have to hold back stick for the first hour or so till fuel burns off. Itwould be handy to trim for a more neutral stick, regardless of whether or notit was handy enough to use for trimming for approach.I think 55-57 is the sweet spot for approach speed in smooth air in most Piets,but 2 or 3 MPH either side of that can make a pretty significant difference inhow the approach goes. It's good to see the number that works for your Land-O-Maticapproach.Last thing: watch out for the Hun when you're vulnerable like you were on thatapproach (sun in your eyes). He'll come down right at you from high overheadwith guns blazing and you won't see him till it's too late and you hear bulletszipping through the wood and fabric ;o)--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
