Gas-tight with no metal being mashed. Agreed . . . "relaxing" of any metal under pressure is alloy dependent . . . I don't think we worry much about thousands of riveted joints in aluminum structures getting loose due to viscosity of the metal. I'll poke around the AMP application notes and position papers on aluminum conductors. If ANYONE knows all the details, it has to be AMP. Bob . . . Bob Eric, I've been following this thread with interest when possible. I'm interested 'cuz I'm building a kitfox with a 28 AH RG battery in the tail to balance a Lyc O-235 engine. The kit came with a 4 AWG copper wire to run from the battery contactor to the starter contactor (about 17 feet!) recommends grounding through the steel frame. Based on The Connection a short discussion with Tim Hedding at BC, I'vedecided to run a separate ground wire but it was tough 'cuz I'm trying everywhere to hold my weight down as much as possible. Iwould really like touse CCA wire but, regardless would like to be sure I'm using wire of sufficient size without over-doing it. I'm running a Sky-Tec Starter (pretty sure it's PM) single electronic ignition with a 28 AH RG battery. It is about 17 feet from master to starter contactor and about another4 or 5 feet to the starter. Assuming copper wire, could you please recommend a minimum wire size for both the positive negative leads? Any other comments are welcome too.

Bob . . . ________________________________ Message 16 ____________________________________ Time: 10:27:17 AM PST US From: "James Foerster" Subject: AeroElectric-List: combining a PM and conventional alternator --> AeroElectric-List message posted by: "James Foerster" Bob, I have a Jabiru 3300 engine with a 20 amp PM alternator to which I have added a B&C spline drive 20 amp alternator. This latter unit may not put out 20 amps directly driven from the crank, but it will certainly do 10- 12 amps which will be plenty. I plan to use a Z-14 type of system with the PM alternator connected with the overvoltage crowbar and s702-1 relay. This will be the main alternator in the Z14 diagram, and be connected to the starting battery and lighting system. The B&C spline drive unit will be connected to the e-bus and a 5 amp-hour battery. It will have a LR-3 controller. I am committed to this arrangement for weight and space reasons. The main contactor will be a Kilovac 200, which only draws 115 ma steady state, and thus does not need to be turned off to save power if I lose an alternator. It continues to serve the traditional isolation role and is labeled 'master A'. The B&C alternator will be wired as depicted in Z14 "aux alt" position, but the S701-1 aux battery contactor will be replaced with a S702-1. I am considering other alterations, too. Questions: 1. Since I will not cross-feed the batteries for starting, I know that I can replace the big S701-2 cross-feed with a smaller S702-1 relay. Could I get rid of the relay altogether and just use a cross-connect switch? No more than 10 amps would be drawn by the e-bus at any time, and probably much less. I'm fairly confidant that this change should be OK. 2. Could I replace this cross-connect switch with a diode, and get rid of pilot intervention completely? I'm not worried about voltage spikes on the e-bus, just voltage sags which reset the EFIS. I will have low voltage annunciation for both batteries. I can't think of any situation where I would not want the main bus to contribute to the e-bus if the PM [main] alternator is working, or if the main battery still had power if the small e-bus 5 amp-hour unit runs low. I don't want the main bus to draw from the small e-bus battery, and the diode fulfills that need. However, if the PM alternator fails, the B&C unit could contribute to the main bus, and a cross-connect switch, in parallel with the diode, could fill that role. I'm not at all sure how to analyze this choice. 3. Should the PM (main) alternator be connected to the battery side of the Kilovac contactor as in Z13, or to the load side as in Z14? It does have its own pilot controlled disconnect relay in the form of the S702-1. If it is on the battery side of the contactor, I can shut off the nav lights, strobe, landing lights with just the Master A switch, while still getting power from the PM alternator. I'm lost on this question. Thanks for your help Jim Foerster ________________________________ Message 17 ____________________________________ Time: 10:27:26 AM PST US From: "Robert L.

Just published a DIY audio mixer circuit data package at http://www.aeroelectric.com/whatsnew.html You can build the monophonic version on the ECB I can supply or you can get your own from ExpressPCB.com Artwork file is at: http://216.55.140.222/Catalog/AEC/9009/9009-301-1.pcb You can expand the number of inputs indefinitely by adding any needed 150-ohm/10-uF combinations for each new input.

I just got finished pre fitting this panel. Wish I had another pair of hands. Basically in "MY MANUAL" of 1996, the top of the panel is about 880mm with the center of the panel aligned with the center line of the fuselage followed by a measurement of 500 mm at center line, level, at the bottom of the panel. Your ES is newer, and I believe your panel is different. I have already filled and put two coats of primer on the bottom. I suppose I could put the final coat. Speaking of paint, what design are you guys thinking of? I have gone to Lancair Legacy.com to see several designs. The Legacy seems to have some similar lines, just a shrunk ES. You mentioned BUS placement. Sitting in the approximate area of the plane today while fitting the panel, I did think of BUS placement. Thinking "SOLO," my first thought is probably on the cabin side wall of the passenger side. Reason? With the A/P on, it would be easier to check a fuse leaning in that direction. The second area would be to build some kind of center console with fuse rows. As soon as I get my Dynon EFIS 10, I'll send some photos.

About a year ago, one of the RV List members had a problem with ACS and called the president of the company, Jim Irwin. He reported back to the list that Mr. Irwin took care of the problem and went "above and beyond" for him. I mention this, because it swayed me to do business with ACS recently. I used their web site to order all the parts. I had a copy of their 2002/2003 catalog as well. I was pleasantly surprised to find that most of the items I ordered had gone DOWN in price compared to the catalog. All the items I ordered were in stock. Ordering on line let me know that before the order was complete. I received several email communications to let me know that ACS had received and processed my order. The order arrived 3 days after it was placed. Everything was there and "as advertised". Please count me as a satisfied customer. I'll be placing another order with them this weekend. FYI I price shopped for all this stuff. ACS has the hands down best prices on AN hydraulic fittings. The "auto racing" places don't even come close. I have ordered parts from ACS's competitor Wicks in the past. I've always been happy with them as well. I placed an order with Wicks the same day I placed my ACS order. I had numerous problems using Wicks web site to order. I finally gave up and had to call them to place the order. So ACS scores a #1 with their web site as well. I hope this all gets straightened out for Mr. Seemann. I suspect that the problem is with the shipper or customs. Charlie Kuss RV-8A cockpit systems stuff.

I'm not at all sure how to analyze this choice. Are you making this too complicated? How about the all-electric airplane on a budget. The SD-20 alternator driven directly from your crankshaft will be good for 40A. I'd make this the main alternator. Hook the PM alternator up as a standby and single battery changed out every two years max. You could stay with a much less expensive S701-1 battery contactor, power to keep it closed is not an issue. >3.

I'm lost on this question. Given what I understand your system right now, if it were my airplane, I'd go with Z-13 and keep it simple. This configuration gives you reliability most twin engine certified ships don't have. Just keep a fresh, 17 a.h. battery in place and you're set to go.

How did they say your package was shipped? Did they send you a tracking number? Have you tried their customer service phone number? 800-861-3192 If you're getting automated e-mail responses, then I think you're sending your e-mail to an address specifically set up for order status inquiries. Try custsvc@aircraftspruce.com for contact with an individual or as last resort, the 800 phone number above. If your order shipped, then they'll not have any way to know where the parts are except to query the shipper's computer using a tracking number. I've not ordered from Aircraft Spruce lately but I would be surprised if they didn't send you a carrier name, URL for package tracking and a tracking number. If you did receive this data, then you need to take it up with the shipper. Once confirmed that the package is lost, the shipper will pay you for it and you can place a new order with Aircraft Spruce.

I'm interested 'cuz I'm building a kitfox with a 28 AH RG battery in the tail to balance a Lyc O-235 engine. The kit came with a 4 AWG copper wire to run from the battery contactor to the starter contactor (about 17 feet!) recommends grounding through the steel frame. Based on The Connection a short discussion with Tim Hedding at BC, I'vedecided to run a separate ground wire but it was tough 'cuz I'm trying everywhere to hold my weight down as much as possible. Iwould really like touse CCA wire but, regardless would like to be sure I'm using wire of sufficient size without over-doing it. I'm running a Sky-Tec Starter (pretty sure it's PM) single electronic ignition with a 28 AH RG battery. It is about 17 feet from master to starter contactor and about another4 or 5 feet to the starter. Assuming copper wire, could you please recommend a minimum wire size for both the positive negative leads? Any other comments ar! e welcome too. 2AWG or it's equal in CCA wire (1/0) is recommended. How's your weight and balance look if you have a 15# battery? You can save 13# in battery and use part of the savings to pay for taking battery (-) up to the firewall ground stud on it's own CCA wire. Overall weight savings would be substantial as long as you don't NEED more ballast at the battery location. Bob . . . I would LOVE to use a lighter battery but I've been told by sources I believe to be reliable that I can't know the WB situation until I am fully covered painted. Is that your understanding too or is there a way I can figure it out ahead of time? As Skystar sent me the heavy battery told me toplace it as far back in thetail as possibleI would guess shaving 13 lbs off the weight would put me out of the CG envelope. However, I have gone to great lengths to keep weight out of the airplane and especially out of the nose(e.g. light weight starter alternator, electronic ignition minimized length of propellor extension) In the event that I am able to use the lighter battery, could you post the make model of the one you're thinking of?

If this does not work, just use kilovac.com and start from the first page. The spec sheet is impressive, and at the end gives you the precise model number that you need--I've listed it in the next paragraph. The distributor is http://onlinecomponents.com and you search for EV200. The model number that you need is EV200 AAANA, which has a 9-36 volt coil, and no auxillary switch to indicate "on". This is about $85 quantity one. If you do want an auxillary switch, the model number is EV200 HAANA, cost $91 each. Jim Foerster
