Re: Mail Newsletter information ---------------------------------------------------------------------- Subject: Re: Trim Systems From: "Tom Andersen" Date: Thu, 21 Jan 1999 20:34:48 -0500 X-Message-Number: 1 Dana, If Troy has implemented an R/C servo then he knows more about it than me. When Troy gets on the net that will be a question for him for sure. Here's some ideas though. I like idea 1 cause it's cheap. Idea 2 will fly quite nicely. Idea 3 is idea 2 with altitude hold. Idea 4 is commercially available in R/C magazines. Idea 1: Most guys remove the electronics and just connect a two D batteries to the motor, and reverse the current using a DPDT switch. This works ok but has no feedback on position. Of course a very thin pushrod could be run to the cockpit from the ARM of the servo to show it's position. (The .080 weed trimmer line moves very freely inside 1/8" Teflon tubing, and would make the most inexpensive position indicator). Your electric trim system would cost about $50 including the switch and servo. At this rate you could do one for the ailerons too, and still be $80 less than one commercial unit. The aileron trim tab doesn't need feedback position if you put it on the left cause you can see it. Idea 2: My (complicated but higher functioning) idea was to use a servo test box ($28) on an R/C 1/4 Scale Mega Hitec servo ($35). Then I could precisely dial in the amount of trim desired, the potentiometer position is my trim indicator, and the servo is constantly powered to HOLD the position set. Then with one of each of these setups on the ailerons and elevator, plus one of the new R/C autopilots ($50 2-axis leveler) I would have the poor man's autopilot and two axis trim system for about $250. The servos would not only hold the trim position set, but also move as an autopilot to dampen excursions and stabilize things. Idea 3: Ideally I'd love to set up the pitch servo for altitude hold instead; maybe an altimeter could be adapted. Then I could set my altitude, turn it on, and concentrate on more important things. Idea 4: There's also BTA's unit (and Israeli company) with three-axis solid state gyro stabilization for about $350 which is 3-axis and has been used in this manner on experimental aircraft already. I know some of you engineers will cringe but this is the way I do things, I use the TLAR method based on educated guestimation and gut feelings in lie of engineering analysis. -Tom -----Original Message----- From: KR2616TJ@aol.com To: KR-net users group Date: Thursday, January 21, 1999 7:53 PM Subject: [kr-net] Re: Trim Systems >In a message dated 1/21/99 6:40:09 PM Eastern Standard Time, drdean@execpc.com >writes: > ><< I know awhile back there was a discussion about using RC servos for the > elevator trim tab, but after looking back through things, I can't find if > somebody had a simple setup for this.

It is a bit pricey compared to the R/C servos, but it does make an excellent setup. I installed mine inside the fuselage, with an R/C style pushrod going to the tab. The MAC company is first rate and their address can be found in the back of Sport Aviation, The Experimenter, and probably Kitplanes magazines. -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ---------------------------------------------------------------------- Subject: Update on AS504x NLF airfoils From: Steven Eberhart Date: Fri, 22 Jan 1999 07:46:01 -0600 (CST) X-Message-Number: 4 Following is Ashok's reply to an email I sent him about the status of the airfoil project from his and Dr. Selig's standpoint. Be sure and read his comments. Looks like we can expect a modified AS5048 18% airfoil. Also check out the technical papers he and Dr. Selig have recently published on low speed airfoil design. Remember, we all helped by funding the design and wind tunnel testing of the AS504x family of airfoils. Not a bad legacy for a group of homebuilders. I am sure Ashok wouldn't mind a few congratulations from the airfoil fund contributors on his wife and his new Christmas present. Get the details from his email that follows. Steve Eberhart ------------------------------------- http://www.newtech.com/nlf ---------- Forwarded message ---------- Date: Thu, 21 Jan 1999 22:36:08 -0600 From: Ashok Gopalarathnam To: Steven Eberhart Cc: Dr. Michael Selig Subject: Re: AS504x airfoils Hi Steve, Thanks for the pictures of Troy's KR-2. We are looking forward to his first flights with the new wing and his impressions. About getting the coordinates of the new airfoils on the web: I have to admit that I just haven't gotten around to doing my part. I have been pretty swamped with a lot of work since I returned from Mojave. I have also been pretty busy at home. My wife and I got a great Xmas present - our first baby was born on the 24th Dec. His name is Shreyas, he weighed 6 lbs. 8 ounces (gosh, what's that in kg ?) and was 21" long at birth. Dr. Selig and I felt that before we put the coordinates on the web, I should smooth out the small bump in the trailing edge region of the AS5048 and check it out with an XFOIL analysis. I just haven't got to doing that work so far and that's the reason for the delay. It is on my to-do list. I'll get to it eventually. Yes, I am definitely interested in working on more airfoils for the KR-2 and other airplanes. Right now, however, I am focusing on trying to graduate before or during the summer of this year and that's going to take most of my time. Hopefully, Troy's airplane will demonstrate that the airfoils are as good as we expect them to be. While on this topic, Prof. Selig and I presented two papers at the AIAA conference at Reno last week. On of the papers was on using inverse design approach to low speed NLF airfoil design. The objective of the paper is to demonstrate the design approach (and not to present any airfoil design for a specific application). Nonetheless, I am sure you will find it interesting. Please feel free to download it from http://amber.aae.uiuc.edu/~ashok/pubs/ and please let others in the KRnet know about this paper.

The simplest setup I've seen (I think in an old Newsletter) is to get a small servo and put the whole thing inside the bottom skin of the elevator, with a small pushrod going to a bellcrank on the trimtab. That way the only thing going from elevator to fuselage would be the wiring itself, which could loop down below the hinges. Ordinary two-wire white lamp cord would look good in such a location and would be cheap enough to replace at the annual. I think the originator of this idea glassed his servo into the elevator, but I think I'd use screws for easy repair. By the way, I would never bother with a position indicator on a trim system, since I think they're useless. I set trim with the indicator only on the first takeoff of the day, and I could just look at the trimtab to do that instead. After that, all trim adjustments (including subsequent takeoffs during touch & gos) are by feel.
