Drilling out solid rivets is not my idea of fun! I thought about clamping on 2 wooden beams, but then how do you set the rivets? The book says set with rivet sqeezer, but i dont want to chance this, just now its out when I'm finished? Thanks, Dirk. 701 # 5228 Kit. ________________________________ Message 2 _____________________________________ Time: 02:18:49 AM PST US From: Matt Dralle Subject: Zenith-List: 2004 List of Contributors - A Special Thank You... --> Zenith-List message posted by: Matt Dralle Dear Listers, First let me say Thank You to everyone that made a Contribution in support of the Lists this year!

Why would you need this? I suspect that many aircraft will NOT trim out to straight and level flight with full flaps. Full flaps are not intended for straight and level flight. Does it trim to minimum approach speed on a reasonable descent to the runway? Unless I'm missing something I can't see the need... Having said that -- can you give more authority in the desired direction by taking some from the other end? I.e. the aircraft doesn't need to be trimmable above max. cruise speed. If there's still more trim available on that end, consider adjusting the neutral point towards 'nose up'? fwiw -- Grant Corriveau C-GHTF / HDS / CAM100 ________________________________ Message 4 _____________________________________ Time: 05:32:32 AM PST US From: Hal Rozema Subject: Re: Zenith-List: Wing trailing edge --> Zenith-List message posted by: Hal Rozema Dirk Slabbert wrote: >--> Zenith-List message posted by: "Dirk Slabbert" > >Mornin 701 builders, >Got the skins cleco'ed now, but worried about getting the trailing edge perfectly straight, does anyone have advise on how to do this right the first time? >Drilling out solid rivets is not my idea of fun! >I thought about clamping on 2 wooden beams, but then how do you set the rivets? >The book says set with rivet sqeezer, but i dont want to chance this, just now its out when I'm finished? >Thanks, >Dirk. >701 # 5228 Kit. > > Hi Dirk: I placed a piece of good straight wood the length of the wing, 2x2 or 2x4, and clamped it all down to my work bench being careful that the upper skin laid flat. Then I drilled for rivet locations through into the wood. I started in the center and worked out each way , one right and one left, picking about every third or fourth location first. Drilled the hole and inserted a clecco right into the wood which clamps it all to the wood. The skins lay absolutely flat and without a bulge between. Then progressively drill and clecco for the balance of the rivets. Next, remove the cleccos to remove the wood and re-clecco . It should still remain dead flat and straight without the wood support. Proceed with the squeezed rivets. Mine came out eyeball straight and true which is as good as I need for my 701.

Dirk, Assuming your talking about the wings. Clamp the trailing edge together with a piece of wood (1x3) on the under side making sure it's flat to the angled edge of the skin. This will help keep it ridged. You want to make sure the trailing edge is flat. Place a straight edge along the top side at the trailing edge to be sure it is flat, not that the edge is flush, but the top is flat all the way along & reclamp. Don't try to bend the trailing edge up or down to make it flush. Any areas that are uneven can be filed flush later. Then, you can start drilling the pilot holes right into the wood & cleco through the skins into the wood. After it's riveted you can file the trailing edges flush.

What I did was to put the gasolator just in front of the spar on the floor (between the rudder cables) and use that as the tee..(drains thru the floor). The chck valves go befor the gascolator and the pumps go in the wing root at the discharge of the tank. I also put a filter on the DISCHARGe of each pump. Junk the engine driven pump, that just encourages vapour lock and over pressurises the carbs.....This is what I have been flying with for 350 hours now.

The PFA who issue (hopefully!) my permit to fly feel this is not as it should be.

The first thing I did was to duct tape an extension on the trim tab to see what it would take to trim it out. With the tab nearly doubled in size it would trim out but it still took most of the trim travel. This was at a forward CG. After this I raised the rear of the horizontal stabilizer half an inch by replacing the rear attach brackets. Now, with the original trim tab, I can trim it out for zero flaps throughout the CG range and with up to about 10 degrees of flaps at aft CG. I still can't trim it out at full flaps. I may rivet a sheet of aluminum to the trim tab to extend it beyond the trailing edge in the future if the problem irritates me enough. It would be nice to not have to hold a lot of aft stick force on final approach to a short runway, it would reduce the workload during a critical time. I don't really need the flaps most of the time, I can usually get it down and stopped in about 500 feet without them. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru.

Although a high wing plane would be better suited for these missions. I know every Cessna I've ever flown can be trimmed out at full flaps right down to near stall speed. Perhaps the British rules require it. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru.

From: "Jeffrey J Paris" --> Zenith-List message posted by: "Jeffrey J Paris" Thanks a bunch! HappyHolidays and back to wiring! Jeff --- On Sun 12/05, < RURUNY@aol.com > wrote: From: [mailto: RURUNY@aol.com] Subject: Zenith-List: Re: Questions about Dynon EFIS D-10? --> Zenith-List message posted by: RURUNY@aol.com Jeff, The Dynon D-10 has a built in altitude encoder and outputs this in standard gray code used by most transponders(11 wires). The new Dynon D-10A also has a built in altitude encoder but it is a serial output only (1 wire). You would need a newer transponder such as the Garmin GTX327 to use the encoder. If you have your transponder already hooked up to a separate encoder you can just leave it like that and install your dynon. The dynon will not use your existing encoder for anything and does not need an external encoder for any of its functions. The dynon has an encoder built in it for its own use and for output to your transponder. If you have the newer dynon D10A and an older transponder you wouldn't be able to use the dynon encoder for that transponder anyway. If the transponder and the dynon are compatable you could wire your dynon
encoder output to the transponder and sell your existing encoder. Using the soft keys on the dynon, you can set the barometric pressure manually. Hope this helps.

The Dynon includes an encoder that you can hook up to the transponder but since you already have an encoder you don't need that function. This will simplify your wiring harness. The Dynon does have barometric adjustment for the altimeter. Jeffrey J Paris wrote: > --> Zenith-List message posted by: "Jeffrey J Paris" > ... Lastly, am I overthinking this thing and should I just forget the hook-up and live with the fact that the unit will not be adjusted for barometic pressure? > s provided by the tp://www.matronics.com/browse/zenith-list Join Excite! - http://www.excite.com The most personalized portal on the Web! ________________________________ Message 14 ____________________________________ Time: 12:13:50 PM PST US From: Jack Russell Subject: Zenith-List: elt location aft --> Zenith-List message posted by: Jack Russell Hello folks: How is your weight and balance working out on the XL's? I got a ameri- king 450 elt ( a fairly heavy unit with the D cell's) and would like to put it in the tail if it won't sent the CG to far aft. I am a little worried about the jabiru engine being a little light for the design of the airframe. I do have an oddsey battery on the firewall. As always, I appreciate you input.

The info below came from someone who has little knowledge of Jabiru engines, in fact he thinks they're tested below sea level. The spring in the Jabiru mechanical pump is customized for the engine. You can pump through it if it fails, just ask USJabiru or Andy at SunCoast. A Jab is not like a Subaru/Stratus, which does not come with a fuel pump. I'll resist the urge to say more but add that the US factory distributors know more about their products than do the various opinions on an e-mail builders list. Ask the people who know. regards jeff >Junk the engine driven pump, that just encourages vapour lock and over >pressurises the carbs.....This is what I have been flying with for 350 >hours now. ________________________________ Message 16 ____________________________________ Time: 01:13:33 PM PST US Subject: RE: Zenith-List: Re: 601XL Fuel Valve and duel control problem From: "Hinde, Frank George (Corvallis)" --> Zenith-List message posted by: "Hinde, Frank George (Corvallis)" My applogies but I did not see the engine was a Jab. The Rotax and the Stratus use the same bing carb which can be a problem when you have two pumps in series (low wing pump and the engine pump) because the pressure can overcome the float needle. So to junk the engine driven pump on a Rotax is perfectly OK...becuse it has Bing carbs. The problem with an engine driven pump is that it is prone to heating and if it is used on a low wing plane with auto fuel with no low point pump it is a prime candidate for vapour lock. If your engine has some other form of fuel metering that is fuel pressure dependant (MOST carbs do not care what the pressure is as long as it does not overcome the float needle) then of course you need some way to accuratly deliver that pressure. My point was intended to demonstrate that a engine driven pump only is a poor way to do it.
