Have had them for over 4 years and 500 hrs now. My experience with service and support has been good. Depending on the Generation of EFIS it may or may not be the right one for you. It also depends on what you want it to do. If you are going to use a Garmin 430 or 530 or an autopilot other than BMA I would not get a BMA EFIS especially if it is a pre gen 4 EFIS and even then I would be hesitant. They work great with an SL 30. Also the pre gen 4 units will never be upgradable to the features of the generation 4 units so what you get is what you will have. I enjoy flying my Gen 1 EFIS 1 but it just cant compare to my Gen 4 Sport in features and function. Support right now for the pre gen 4 units is slow but improving. BMA had a real nightmare of a launch with the Gen 4 products and appears to have gotten most (not all) items resolved and hopefully they are now going back and finishing the un resolved issues with Gen 3. For me the BMA units did all the things I wanted at the right price and weight. The delivery delays were not an issue for me but for some they caused considerable problems and rightfully made a lot of people really angry. Hopefully this is all in the past. In any event fully evaluate your needs in an EFIS and what you expect to integrate it with and then look at all the options available. If the BMA unit fits the bill and is at a good price I wouldn't hesitate at buying it. -------- Milt 2003 F1 Rocket 2006 Radial Rocket Read this topic online here: http://forums.matronics.com/viewtopic.php?p=157952#157952 ________________________________ Message 2 _____________________________________ Time: 05:43:02 AM PST US Subject: AeroElectric-List: Intercom Troubleshooting Help Needed From: "DaveG601XL" I put power to my PS Engineering PM501 intercom last night for the first time and have a problem that has me at a dead-end. When I powered it up, the fuse blow immediately. I metered the power lead to ground and got infinite resistance which tells me that there are no dead shorts in the wiring. I moved the power circuit to a breaker, just to eliminate the fuse from contention, and it also popped. Again, no short to ground with the meter. When the unit is switched off, power can be applied and the breaker will stay latched. This also appears to tells me that there are no dead shorts in the wiring. It is only when turned on that it blows. Is this a problem inside the box that I may not be able to troubleshoot, let alone fix?

I'm not sure if they do this actively or not but I have sent them three requests to get on their web board and they don't reply. I gave up so I don't know what they would say if I pressured them. Besides, I can only deal with their attitudes for about five minutes a month and I didn't want to use up all my gum balls. Here are some of my more recent stories regarding BMA: I ran into a guy that had two Blue Mountain EFIS One's in his Harmon Rocket. I was looking at it and I asked why he also had two Dynon's right next to the EFIS One. His response to me was the EFIS One would fail all the time and he would simply pull the unites and send them back every oil change because the most he would every get out of the unit was about 40 hours. He has over a year and a half on the units and was going to remove them this winter. This story was from August 2007. This is a story from my unit: A BMA EFIS Lite G3. For those of you who read the BMA web boards there is a story about the altimeter freezing up in flight. The response is that it can't happen from the BMA folks. I have had that problem twice and was told over the phone that that can't happen. So I looked into the mirror and said it must be me and the altimeter is really working and the ground is just not staying in the correct spot. (on a serious note, I think the problem is a thermal issue, I think the unit needs forced air to keep it cool so far that seems to be working. "I fear the day I have to use it in the clouds fortunately it only backs up a real EFIS and I added a stem gauge!") This last story is in progress: I have a coworker who is building an RV8 fastback with a partner. Both are detailed people are doing a high end build with all the bells and whistles. Attention to detail is a 10 (I'll send photos). One of them is an EE and knows his way around electronics at the micro level. They purchased a BMA EFIS one and have not flown yet. Most of the probes had to have trimmers installed so they would read accurately throughout the range of operations (I told you they were detailed). Most of the probes went out of cal out of nominal rest. I will post when we get to first flight.

PSE has always gone over and above for me both personally and through the shop. If you purchased it second hand, call them and see what they can do, I'd bet the repair wont be very much. Based on your report of the failure, I think the unit has an internal failure. It doesn't sound like it should be that complicated to repair. It sounds like a power control problem.

The red end only goes about 1/2 way around. The other end goes about 80% of the way around the pin. If your tool looks like the white end of Bob's picture, it should work without a lot of force. In fact a delicate touch and patience is necessary. For some reason, it takes a long time to get the first one or two out, but once you develop the "feel", they are pretty easy. Force won't work! The white end is fairly thin and easily bent. You might want to review Bob's entire procedure at http://aeroelectric.com/articles/D-Sub_Pin/Pin-Extraction.html I cursed a lot of pins out using the wrong tool that looked like the red end before I learned the difference.

Nicely made and more compact than I expected. Works well in a vice. Not sure about holding the frame with a wrench or whatever say in the plane. Haven't used it yet for the larger battery cables, but looks like it will work up to 1AWG or so. The tool's not really designed for 8AWG, but if the ferrule is thick enough (or I suppose if you add a few wire strands to a 8AWG wire in a 6AWG terminal ala Bobs soldering technique), it works pretty well. Very nice circumferential squeeze on the ferrule. I used 6AWG splices to join MAXI fuse holders (6AWG wire) to 8AWG Tefzel, and it worked fine. No extra wire strands required. Snip From: "Michael D.

Read what is written there. Their Gen 3 products do not work for the purpose intended. Instead of fixing that product and making things right for their customers, they're busy working on the next revision...which they subsequently sell to customers in a broken state. A flight computer for a GA aircraft lives in a very constrained environment. Temperature ranges and inertial forces have well defined limits. There is no excuse for a unit not to be tested to the extent of those limits. The fact that they would repeatedly push untested products into a potentially life threatening situation says to me that the company is less than ethical. ________________________________ Message 9 _____________________________________ Time: 08:41:52 AM PST US From: "Ralph E.

I have the pin wiring diagrams from Bendix/King showing what pin does what, but I'm confused about the pin labeling. I referenced Bob's site at http://www.aeroelectric.com/Installation_Data/KX155.pdf and http://www.aeroelectric.com/Installation_Data/KT76A-76C-78A.pdf but my unit has a different number of pins. My A1 board is only 15 pins and the A2 board is 11 pins. How are the pins labeled (1-15, a-z, etc.). Also, what letters are skipped (I, O)? Second question: I realize the transponder antenna should not be bundled with other wires, but is it okay to bundle the COM and NAV antenna cables with other wires?

It will never do it during a day flight, and only during the day when running strobes. I can induce it at night fairly easily sometimes with the navs, fuel pump, landing light, and panel lights (no strobes needed..they seem able to induce the problem by themselves). I was returning from Miss. a few nights ago and it decided to do this. I shut down the strobes and everything was fine (as usual). I turned the strobes back on and the last 30 min or so of the flight was uneventful. I installed a new B&C battery yesterday and the problem occurred again yesterday evening 1 time near the beginning of the flight, and more so on the ground after I landed and had the engine at idle power. I stayed in the pattern since I had a "known" electrical issue. Here are few things I may have forgotten to mention, and I can't be sure if this could be a cause of my problem. 2) I notice both my EI voltmeter as well as the Dynon (backup to my gyro ;) ) are reporting about 13.5V when in flight. I would assume this should be around 14.5 or so. I think before this problem it did. Funny the little things you start to notice when you actually have a problem. 3) The main problem is that if under load, the system will "shut down" the charging system intermittently and then come back online. Sometimes in a rapid (5 secs or so) succession or sometimes in more erratic unpredictable intervals. Like the flight back the other night, it acted up then stayed online for the remainder of the flight. I'll see the voltage annunciator come on and the voltage drop to 11.8 or 12...then it will go back up to 13.5. It may stay for a while...the remainder of the flight...or maybe 10 secs. It's crazy. I thought I had the alternator tested at one time and was told it was fine. I also just replaced my main solenoid (it was going bad..wouldn't connect when I turned the master on). That's fine now, but that didn't help the problem either. This problem is driving me crazy. Any and all input would be appreciated. I'm almost convinced I'm never going to find the root if this thing. Thanks again.

I have written four posts today on this subject on two different sites. I have been nice and danced around the issue figuring that all could read between the lines. But for you let me be direct, if a boat anchor is what you need then BMA is for you. If you want to fly in the clouds then BMA is not for you....

You work in military avionics yet ou think that airplane guys who move into electronics produce much better EFISs and autopilots than "electronic guys" who move into airplanes. I'm not sure what you mean by "electronic guys," but I suspect it is workers who produce commercial products. That's like Lenin claiming that communism is better than capitalism. I also do not have direct experience with BMA products, but I've seen their reps at airshows. They seem to know what they're talking about just like the other guys. If they're having problems, I am willing to bet that they are business related decisions, i.e., shipping too early to meet deadlines, not ordering enough parts on time, technical problems due to hurried schedules, etc. These problems plague any organization that isn't run properly. It has nothing to do with whether someone has military experience or not.

Ask about the background of the company who built the product and make a decision accordingly. I have no direct experience of BMA products, but their representatives at the various airshows did not talk enough 'airplane' for me.

I think that for the price, they offer the most capable and current functionality, but I think you need to be choiceful with your upgrades because being first can mean things aren't as solid as many expect. I'd rather have the option of perfectly stable or leading tech with some possibility of issue - at my discretion. They are certainly not for everyone.
