Having stall warning devices and idiot lights seem to be overkill on our RVs. There are hundreds, most likely thousands, flying that have neither. I sort of put them in the same category as the timer that beeps to remind one that s/he has to switch tanks. If one flys often, these devices aren't needed. Besides, each of those devices adds to the complexity of the aircraft. Complexity adds failure points. I must admit that I do support having a backup basic instrument that's required to fly VFR, such as the oil pressure gauge, oil temp, etc., in case the main device fails. No matter how good they are, electronic devices can fail. Other than that, I'm going to trust the device to work if I spend big bucks to buy it. I currently fly by steam gauges and instruments. I may install a Dynon in my new RV, in spite of it's little problems, just to give me some panel space. If I do, I'll have a back up Altimeter and AIS, just in case. All other instruments and gauges on the Dynon will have to be done without, if the unit fails. No idiot lights, no stall warnings, and no beepers for switching tanks. I must admit that I did think about a beeper for the canopy, though. I decided to not install it and have left mine unlocked a couple of times in the five years I've been flying it. It was no big deal. I landed the airplane and locked it down. The airplane flew just fine with it loose. With that, the beeper idea went bye-bye, as well. Besides, I ignore the little chimes in my cars. What makes me think I'll not do that in the RV. :-) Each of us must build to our comfort factors. I guess having these devices make some feel more comfortable. I have a friend who decided it would be a good idea to have a stall warning device. He installed a AOA device for that, even though I kept telling him he didn't need it. He found out quickly that I'd told him right. He didn't need it. He regretted installing it, after that. If one flys often enough, most of these devices are not needed. However, you build your airplane to your comfort factor. Do try to keep things as simple as possible, though. Your additions may fail, as well.

With the messages over the years about these systems. Which sump part does what. Will this part fit this engine and so forth, I felt it appropriate to archive this great website where the author has taken the time to lay it all out, pictures and all, with detailed descriptions. Zooming in on the pics and you can actually easily read the text clearly. That's a nice change of pace. Also good discussions on exactly what each part is doing when your inverted and how it all works, various sump modifications, system selection based on engine model, all the little doodad parts and descriptions, components and dimensions, kit options, blah blah blah. First time I ever ran across a site so thorough on the matter.

I have an electronic engine monitoring system that's serial number 1 (of 2). Even though it's been very reliable over the last 4-5 yrs, I've had one failure that turned me back half-way through a nice little weekend trip. I have a separate pressure switch that activates my hour meter. It's on my future to-do list to come up with a scheme to illuminate an LED when the pressure switch opens (low pressure). Just to give a backup indication of a problem. Long term, I'll probably go with something like the coming Dynon engine monitor - primarily so I can have some display redundancy with my EFIS, free up some panel space and I like the Dynon products/company. When/if I do this, I'll probably also install some kind of small backup analog pressure/temp indication.

This gives you a better idea of what your engine is doing before you can sense/feel anything. The chances of a cylinder related problem is much higher than a oil temp/pressure gauge going out. I guess what I am trying to say is I dont understand why you want back up gauges, there are other areas you can improve to have a safer flight. No insults to anyone intended.

The jig is the wooden 'ladder' type from Vans' plans and I have removed the last two crossmembers to support the fuselage on the sawhorses. Free to a good home, for the cost of a single 2x4 (to replace the crossmembers) you get a complete jig. It's located in Flagstaff, AZ. I don't know of any builders up here or how many builders still need a jig, for that matter, so if someone doesn't take it I'll just disassemble it and reuse the lumber. I also have the wing jig; it's a freestanding jig built according to the plans that are on my website. It's made of cedar so it was perfect for building in my apartment living room. While I no longer need to work in an apartment, it'll still make a good riveting stand when I build my next RV unless someone decides to take it first. Also free to a good home. I won't deliver, sorry.

Loose regulated power for the monitor and you loose all EGTs, CHTs, tach, temps, pressures, fuel levels, pressures, etc. I'd imagine other integrated engine monitors have similar weaknesses. Come to think of it, what might provide some redundancy in engine condition indication as well as add helpful info is one of those low oil sump level alarms. IMO, that would be even better than a high temp/low pressure backup indicator. A better plan...

The idea is to get a bunch of high quality photos in sequence to help others along. I have to admit, I have used the photos on everyone else's websites to get tips for my own project (RV 10). I will also be able to reference particular pictures when I get the inevitable questions that I answer every day. Hopefully you guys will be able to pick up some good tips. So here is my offer.....If any of you guys are willing to let me post pictures of your tanks, I will discount my labor for you by 20%. I would like to get one set of pictures for each of the popular models of aircraft. I also really want to get some of the modifications such as capacitive fuel senders and flop tubes. For the gentlemen who have recently ordered tanks and are in my schedule now, you may also consider my offer good (as long as it is not too late to get the picts.) Since I am revamping the website, please feel free to make any suggestions. Are there particular issues you would like to see addressed....pictures you would like to see?

Jim Nelson ________________________________ Message 13 ____________________________________ Time: 09:44:29 AM PST US From: "steve zicree" Subject: Re: RV-List: Stall Horn --> RV-List message posted by: "steve zicree" Regarding the best way to know what the wing is doing, I would suggest getting some good acro training. When I was getting my private, I was troubled by how much time was spent learning what not to do. Don't bank beyond this, don't climb steeper than that, and for god's sake, don't spin. It left me feeling like the plane was just waiting to bite me if I went past some very sketchy limits. Shortly after getting my private, I got some good acro training from Sunrise Aviation. It makes a huge difference in my ability to "know what the wing is doing". This is just my experience, your mileage may vary.

Or even just their Graphical Engine system without the EFIS option but with the EIS. Either way, the EIS itself is a system that's been out there for quite a while in the thousands and for some is more than adequate for their engine monitoring needs. I don't think there's any harm to it if left on while starting up the engine. When you go full bore on the GRT EFIS and EIS you get the EIS as a backup to the EFIS for engine monitoring should you want to startup with the EFIS off until power settles down. If the EFIS system should fail in flight your Engine stuff is still covered by the EIS.

Or even just their Graphical Engine system without the EFIS option but with the EIS. Either way, the EIS itselfis a system that's been out there for quite a while in the thousands and for some is more than adequate for their engine monitoring needs. I don't think there's any harm to it if left on while starting up the engine. When you go full bore on the GRT EFIS and EIS you get the EIS as a backup to the EFIS for engine monitoring should you want to startup with the EFIS off until power settles down. If the EFIS system should fail in flight your Engine stuff is still covered by the EIS.

-- RV-List message posted by: "RV_8 Pilot" Good point on the engine monitor, however in my case, the power supply for the entire engine monitor is common. Loose regulated power for the monitor and you loose all EGTs, CHTs, tach, temps, pressures, fuel levels, pressures, etc. I'd imagine other integrated engine monitors have similar weaknesses. Come to think of it, what might provide some redundancy in engine condition indication as well as add helpful info is one of those low oil sump level alarms. IMO, that would be even better than a high temp/low pressure backup indicator. A better plan...

This gives you a better idea of what your engine is doing before you can sense/feel anything. The chances of a cylinder related problem is much higher than a oil temp/pressure gauge going out. I guess what I am trying to say is I dont understand why you want back up gauges, there are other areas you can improve to h ave a safer flight. No insults to anyone intended.

I have an electronic engine monitoring system that's serial number 1 (of 2). Even though it's been very reliable over the last 4-5 yrs, I've had one failure that turned me back half-way through a nice little weekend trip. I have a separate pressure switch that activates my hour meter. It's on my future to-do list to come up with a scheme to illuminate an LED when the
pressure switch opens (low pressure). Just to give a backup indication of a problem. Long term, I'll probably go with something like the coming Dynon engine monitor - primarily so I can have some display redundancy with my EFIS, free up some panel space and I like the Dynon products/company. When/if I do this, I'll probably also install some kind of small backup analog pressure/temp indication. Bryan Jones -8 do not archive -- RV-List message posted by: "thomas a. sargent" I am thinking about firewall penetr ations and engine hook-up right now. I have a VM1000 engine monitor which will be installed. However, that's a complex device and has a computer in it. Being a computer programmer, I expect the thing to fail on me at the worst possible moment, so I was wondering about the advisability of installing a second oil presure gauge and oil temprature gauge. I would use cheap electrical gauges. Has any one bothered to do this? Is it worth the effort or am I just being paranoid? Redundant oil info might be interesting during normal operation. I could put the temp. gauge at the output of the oil cooler and see how much effect the oil cooler is having at any given moment, for instance. -- Tom Sargent, RV-6A Scott Bilinski Eng dept 305 Phone (858) 657-2536 Pager (858) 502-5190 www.buildersbooks.com! s.com/browse/rv-list ________________________________ Message 18 ____________________________________ Time: 01:25:33 PM PST US From: "Ken Simmons" Subject: Re: RV-List: backup oil temperature & pressure gauge --> RV-List message posted by: "Ken Simmons" I'm sure the monitors from IK Technologies has the multiple power supply setup, but of course verify that with them. http://www.i-ktechnologies.com Ken ---------- Original Message ---------------------------------- From: "Dan Checkoway" >--> RV-List message posted by: "Dan Checkoway" > >Take a closer look at the ACS2002.

There's absolutely nothing wrong with wanting or having a stall warning device (or any other safety system for that matter).

Zooming in on the pics and you can actually easily read the text clearly. That's a nice change of pace. Also good discussions on exactly what each part is doing when your inverted and how it all works, various sump modifications, system selection based on engine model, all the little doodad parts and descriptions, components and dimensions, kit options, blah blah blah.

Essentially, I have everything that Bob Avery lists in his catalog as the RV builders kit (for $2K) with a few minor omissions and a lot of major additions: Extra clecos and pliers Pneumatic rivet squeezer with adjustable anvil 3" yoke 2" yoke 1" thin nose "no hole" yoke a better hand squeezer Pneumatic and hand nibblers pneumatic pop rivet puller Craftsman 2.4 amp die grinder plate nut drill jig Riv-nut tool 5 extra stop countersink cages strap duplicators (#40 &30) Unibits to 3/4 inch extra files and drills extra bucking bars more stuff that I cant remember at the moment $1800 for all please reply off list if interested of course, do not archive Bill Davis ________________________________ Message 27 ____________________________________ Time: 07:06:31 PM PST US From: Subject: Re: RV-List: Re:Stall Horn --> RV-List message posted by: > If a stall warning device isnt needed for those who fly alot, why are they > required on jets that have enough thrust to climb at a 20 degree angle at > over 6000ft/min? > > There's absolutely nothing wrong with wanting or having a stall warning > device (or any other safety system for that matter).

Now, understand that Jeff is a jet jockey for UPS and, if I remember his RV correctly, he has no stall warning device on his RV, either. At least I don't remember one on it when he was building it. That was what I was saying. If you want it, fine; but, a regular flyer probably isn't going to need it. S/he will get a feel for the airplane. Based on some of the landings I've experienced while flying on airliners, some of those pilots probably do need stall warning devices. I know they've thoroughly tested the landing gears. Maybe the wing structures, too. :-) Sorry, Jeff. The Devil made me say it. :-) Jim in KY Do not archive! ________________________________ Message 28 ____________________________________ Time: 08:21:11 PM PST US From: Oldsfolks@aol.com Subject: RV-List: Re: Canopy safety latch --> RV-List message posted by: Oldsfolks@aol.com The Canopy safety latch I listed to give away has been taken.

It has never crept toward the unlatched position in flight. Then again, there's always the next flight!! YMMV Ivan Haecker -4 1115 hrs S. Cen.

I'm installing the canopy and wondering if the extra latch is worth the trouble.

In the wing kit Van's sends you a small "float and wire" diagram to bend the float arm to the right dimensions. I glanced at the ISO view in the upper left corner of the depiction and if you bend the float arm the way they show it there the float body will impact the rear stiffener in the empty position. So if you pay close attention to the 3/4" 90 degree bend you make in the float arm in relation to the float itself you will avoid problems. Take this task slow and systematic. Cleco the sender in. Understand what side the float arm clips in. Study the diagram/dimensions in the lose papers and not the Appox. 3" called out on drawing 16A for the "X" & "Y" bend. In the diagram provided it calls out for specific dimensions and are different for the left and right fuel tank. I hope this helps someone out there before they hit this stage. I will be honest I only realized this when I was all done, bending and cutting. Only when checking the travel of the arm and float did I notice, "bending the 90 degree the wrong way" the float body would have impact the bottom, rear stiffener. I would not want to bend the wire 180 degrees the other way, she'll probably break clean off on you. ________________________________ Message 32 ____________________________________ Time: 10:08:26 PM PST US From: "Dan Checkoway" , Subject: RV-List: ROUTE based decoded METARs and TAFs --> RV-List message posted by: "Dan Checkoway" This isn't rocket science by any stretch, but it is brand new functionality on my decoded weather stuff... http://www.rvproject.com/wx/ Now you can enter origin and destination airports and a course width, and you can get decoded weather along that course (great circle).
