    Hello All. Think! I may have fixed it. Fitted a new Rectifier about 80, Now seeing 12.9 to 13v on the voltmeter with a fully charged battery, Now, Master ON/OFF needle flicks but remains at 13v ( before it use to be 12.1 on and 13 off see past post) I believe I read you should not flick the Master ON and Off with the engine running, so won't do it again as all seems OK now.

    Subject: Rotax 912S mixture vs mag drop
    From: "jonathanmilbank" <jdmilbank@yahoo.co.uk>
    I never cease to amaze myself with how much I've forgotten, or never knew in the past 48 years since I started flying for a living. Admittedly most of my flying was powered by gas turbines, but I have been flying my Europa Classic for 18 years and keep having to "re-invent the wheel." For reasons I won't bore you with, it came about that I needed to fiddle with the carburettor needle positions and after each experimental move of the needles by one notch, I took the engine up to full temperature and performed repeated "mag" drop checks along the way. The long and the short of this is that the leaner the mixture (needles moved down) the greater the "mag" drop and vice versa. If we had different engines with separate mixture control in the cockpit, then this would be glaringly obvious. But I've become so accustomed to single lever engine control, that I've mentally obliterated such out-dated complications. So if you think that your "mag" drop check gives borderline (too much drop) results, consider moving your needles one notch richer. It's dramatic how greatly the results get improved, to well within book figures. Here's a quote and a link: "The leaner the mixture, the more mag drop you'll see on one mag, and that's normal." http://www.advancedpilot.com/articles.php?action=article&articleid=1844 Obviously I never had enough flight time in proper old "heavy metal" aircraft, which teach you a lot.

    Subject: Heavy duty starter for Rotax 914
    From: "Roland" <schmidtroland@web.de>
    Hi all, since I'm planning to move (the much lighter) LiFePo battery http://www.accu-24.de/ALIANT-LiFePO4-Ultralight-Battery-X4-13-2-V-92-Ah from the baggage compartment onto the right footwell and having to change the Rotax sprug clutch this winter (lots of kick backs on starting), I'm also thinking about installing a heavy duty starter like this one http://silent-hektik.com/UL_912_Anlasser.htm . I seem to remember, that it's most advisable to retrofit it on the 912 S with its higher compression. Did anyone of you install such a heavy duty starter on the 912 or 914 or is it just overkill for this engine?

    You say you set the controller to 4800 for cruise. Is that in manual mode? The factory setting is 5100 I think, which is the minimum cruise RPM recommended. I think you might want to refer to the airmaster manual.

    My Airmaster gives 5000 rpm when set to Auto and Cruise. I've been using this excellent propeller hub for over 15 years and had it first inspected, then modified for the wider blades after fitting a 100hp engine. I've never seen anything written which states that you can't set the coarse pitch stop for less than 5000 in manual cruise. My Rotax 912ULS isn't fitted with a turbo and therefore can't be "over-boosted" no matter how low the rpm. The only sensible constraint I was given about setting the coarse stop, was to ensure that if stuck at the coarse limit for some reason, then in the event of having to go around late on final approach, the aircraft should still be able to climb safely at low rpm with full throttle, flaps down and heavily laden. This is easily done at low airfield elevations, with the coarse pitch stop set to allow 4700 rpm in my normal 115 - 120 kt cruise. I can't see the point of being allowed to cruise fast using lots of power while not being allowed to enjoy the benefit of a quieter engine running at lower, quieter rpm. It doesn't make sense when considering that this touring aircraft should be set up to benefit from quieter engine operations to afford the occupants a more restful flight and also safer due to reduced noise distraction. For many years I have cruised far and wide at around 120 knots with the rpm set manually to around 4700 with no ill effects. The reduction in noise generated by taking the rpm 300 lower is very agreeable. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=447899#447899

    I don't really understand how they work, presumably any manual input overrides them but they must be fairly strong to rotate the tube. I guess if you disable it, it disengages the servo and reverts to a normal feel stick. Any recommendations as to a easiest fit set up. I dont have an EFIS I would have to fit something probably in place of my 'steam DI' which I wouldnt miss that much. It would seem a useful device for long flights. Is it an easy standard mod? -------- Graeme Bird G-UMPY Mono Classic/XS FFW 912S/Woodcomp 3000/3W Newby: 200 hours 4 years on the Mono g(at)gdbmk.co.uk Read this topic online here: http://forums.matronics.com/viewtopic.php?p=447902#447902

    Jonathan, I totally agree with all you say. At 1,100 hours and 100 hours after changing my engine to the 912S, I fitted the Airmaster propeller. I immediately set the cruise pitch to 4700rpm through a connection with my computer and I have now done 1,100 hours with this setup and I am completely happy with it. I usually cruise at between 24 and 25 inches manifold pressure which gives a lovely smooth and quiet performance and opening up to 26 inches gives me 140 knots cruise. I have tested it fully loaded and found that I can leave it in cruise setting and climb at just over 500 fpm after take off, fully satisfying any LAA requirements.

    That's what the operator's manual for the 914 says: Run the engine in accordance with the following tabel. RPM MAP inHg Percent of power Throttle position 5800 40 100% Power (Full Throttle) 115% Throttle Position 5500 35 85% Power (Maximum Cruise) 100% Throttle Position 5000 31 75% Power (Normal Cruise) Approx. 85% Throttle Position. 4800 29 65% Power (Economy Cruise) Approx. 65% Throttle Position However my question was concerning the course pitch stop adjustment, which is not to overcome by the controller, not on auto and neither on manual. This prevents the controller currently from setting the blades to a courser pitch. Anyhow I got an answer from Martin from Airmaster recommending to turn the course pitch stop cam 2 turns anticlockwise. I think I'll start with this....

    Dave, Very interesting, thanks. It never occurred to me to change the Auto Cruise setting by means of software alteration. I did it electro-mechanically by adjusting the coarse micro-switch position until I achieved 4700 rpm at 120 kts cruise. Actually this task is made simpler by starting from a coarse pitch setting angle given by Airmaster (as I recall) which puts you near the middle of the ball-park. Thereafter only a minor adjustment or two are needed for accuracy. This method has the safety advantage of making it near-impossible for a controller/computer fault to push the pitch too far into the coarse range, making a baulked landing go-around dangerous (no climb or worse). I left the Airmaster factory settings unchanged for take-off +/- 5750, climb +/-5450 and cruise +/-5000. In my mind these settings are analogous to first gear, second gear, third gear and higher "gears" are achieved by selecting Manual and beeping with the rocker switch. Similarly the fine micro-pitch switch in the hub should be set so that when in manual at about 80 knots it shouldn't be possible to beep with the rocker switch to push the rpm above 5800, thereby preventing damage to the engine. I believe that you should regard the computer/controller governed T/O-Climb-Cruise settings as "nice to have" but not essential. With the hub Coarse and Fine micro-switch stops properly set as suggested above, you are then set up to fly safely in Manual, regardless of software glitches.

Hi Roland, Never had a kickback or any problem on the 914 with a Hawker SB8 battery (2.7 kg) in the back, so you may want to make sure it has not something to do with the starting circuit.

    Subject: Re: Heavy duty starter for Rotax 914
    From: "Roland" <schmidtroland@web.de>
    Bonjour Gilles, I think my kick back Problem is typical for a broken (worn out?) sprag clutch (that's also what Rotax suspects). The LiFePo battery is very strong and I think this Problem should be solved with a new sprag clutch. However the long wiring between the battery and the starter is far from ideal, so I'll change it on this occasion as well. The idea of the heavy duty starter arised, because the engine/starter has 650 hrs now and the engine has to be taken out anyway. Plus the cables should not be longer than 50 cm, which would be the case with the new battery position. So just nice to have, but certainly unnecessary. What I've learned by now is, that several feasible approaches to the problem exist - and, that I'm not the only one having it :-) Salut Roland PH-ZTI XS TG 914 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=447921#447921
