Amelia, You didn't describe what is wrong with your HSI? If you are having needle/flag problems, its the HSI. Heading problems could be the KG102A gyro. Or something else. I have some components removed from a late model Baron. The latest -07 HSI and high serial number gyro. For under $2k you could switch out your 30 year old for a 10 year old system, with no downtime. I'll take your old units in trade, send them off to Bob Bramble to see what we can do with them. Another nice upgrade for a Mooney is to put a Sandel SN3308. I know they are getting older, but it's a real nice way to have an HSI, RMI (add and gps pointers), WX500 stormscope etc. Not the latest glass, but still a very affordable step. Feel free to email me at supercub180@gmail.com Don

I have a system for sale for $3,000 including shipping, excellent condition, passes all internal self tests. Install kit, antenna doubler & gasket, install manual etc. Send me an email to supercub180@gmail.com. Don

I think this is where you are still one step behind… The OWT we were all taught is that the airflow was imbalanced (especially engines like the TSIO 360), hence the imbalance in power, different cylinders reaching peak etc. Continental spent millions designing the 'spaghetti' intakes to balance the fuel flow, first used in the 252, which was a whole lot better, but more expensive and heavier. The brilliance of team GAMi, was to identify that with a constant flow injection system, there is fuel carry over from the one cylinder to the next when the valve is closed. Its not hard to understand that if you are injecting a contionious stream of fuel behind a closed valve it is going to vaporize and expand, thus 'contaminating' the air going to the next cylinder. Solution is to give the next cylinder slightly less fuel, and the last cylinder in line even less. All are getting the same amount of air. I theory the 252 engine is balanced - in practice the calibration of Continental fuel injectors is nowhere near as good as GAMi. Do the GAMi test (with continental or GAMI injectors), then tell us how well balanced your engine is. For those who say that their engine is balanced form the factory, I call BS. Do the GAMi test and then tell us its balanced… And yes, GAMI want the old injectors just to take them out the market, kind of like Continental used to want a cylinder core to get it out of circulation and the repair market.

The 900 / 830 are almost the same size. The 930 is quite a bit bigger, Don

Added link to pictures in my gallery, added Oil T probe to the kit, reduced the price. Other models available.

Stuff gets 'found' on planes all the time. I've seen logbook entries along the lines of 'automotive style engine heater found installed on firewall and removed'. XYZ GPS found installed. Installation inspected and found to conform with...., W&B updated. Not ideal, but with 50 year old planes you have to accept that standards and 'acceptable practices' have changed a lot over the years. In your situation, I would do the following: 1) Keep looking for the logbook entry / previous records / painter etc. 2) At the next annual (or sooner if its worrying you), get your IA to inspect and sign off all the usual items he would do after a paint job. I don't think W&B generally gets redone after a paint job if its a strip and paint (anyone care to comment on this and the results of re-weighing?). Control surface rebalancing - I would say that is a 'must' after a paint job, but check the maintenance manual, it might have specific instructions for each control surface? It's not a huge job to rebalance, and take the opportunity to thoroughly inspect balance weights, for corrosion, turnbuckles, rod ends, install new bolts etc. 3) Inspect for any other hidden damage. Unfortunately I can see an unscrupulous owner / IA wanting to hide an incident, gear up, hail damage, worse? Fix the damage, paint the plane, sell it...But if the owner who had it painted kept the plane for several years after the paint, its unlikely? Don

Yes they are both similar size and will fit in a standard 3 1/8" hole. But they are slightly different dimensions, so you need a different flush mount kit and rectangular hole if you are going that route. Don

Complete 6 cylinder system for sale, nice recently updated unit with complete set of new harnesses and probes. Will include the optional Oil T probe too for $2,950. Will take nice EDM700's and 800's in trade. 4 cylinder system available for $2,450. Don (supercub180@gmail.com) http://mooneyspace.com/gallery/image/35634-edm830-install-kit-and-probes/

I have a new 6 cylinder harness and extra 4 probes if someone wants to turn this into a 6 place EDM830? supercub180@gmail.com Don

Don't assume your new encoder is good - I've seen them fail pretty quickly sometimes. Don

Hi All, I'm a wannabe Mooney owner, had the chance to do some long flights in a 252 and a Bravo. Plenty of time in Turbo Arrows and now a Seneca, so the 252 is my favourite despite what some might think about the engine. Current ride is a Seneca II and a C172 amphib, busy building a Super Cub from a wreck with all the bells and whistles. I can't help myself, end up buying a lot of nice avionics and engine monitors, so have some nice surplus stuff for sale. Day job is developing power projects, had good success with some small hydro and wind projects in BC and Alberta. Currently on a break, so spending way to much time on aviation bulletin boards and the airport CYPK, where I have a nice big hangar filled with projects and airplanes. Don

Twinter (and others), For the most part the probes and harnesses look the same. P1 is still the power harness, but is now 20Ga pwr/gnd wire with a choke and no serial port for data. P2 and the ECT/CHT probes are the same. P3 (RPM/MP/OP) harness the same, but the pressure transducers are different. P4 (FF/GPS) looks the same. P5 (FP,FQ,Amps) is new. My recommendation is to bite the bullet, and buy a whole new set. Work closely with your installer to see what he is comfortable leaving the same (EGT and CHT probes and harness, FF transducer, OAT etc.) and at the end you will have a complete system as removed with some new probes / wires, some old for resale. This is better than waiting for JPI to come up with an upgrade package, because an indicator without probes and harnesses has surprisingly low value because of the cost of building up a system out of spare parts. Contact me for best pricing on EDM700 to 960 systems, new and used, trades accepted. supercub180@gmail.com Don
