    They re-introduced Benzene?, isnt that stuff about as nasty as TEL?

    I'm sure they are great to fly but they hit it hard with the ugly stick (I can attest it looks no better in the flesh) Shame as the original was such a looker

    This one of those 'maybe' matters rather than a certainty, Shirley? Worth looking in to when training, I'll admit it was not on mind at all when I learnt

    AFAIK anaphylactic reactions come on very quickly, I'm sensitive to Bee stings though not to the extent of anaphylactic shock and the sting site starts swelling almost immediately. It's a shame as I enjoyed my short time keeping Bees

    I bought a TY91 transceiver and TT21 transponder about 10 years ago, since then i've changed aircraft twice and both times removed the trig units from the aircraft before sale, so i could fit them to my next aircraft (I now have a spare of each as the Nynja I have now already had trig units fitted when I bought it) They just work, the head units could be improved in the area of usability perhaps but they are reliable and the built in intercom functions well. Customer service has been first class, though I've had no faults I did send the radio back to trig for a firmware update and this was done free of charge with the units being returned in new original packaging as I had thrown the originals away years back.

    Skyecho is rather odd in its charging requirements. There is a very full thread on Charging in the Flyer Forum here: https://forums.flyer.co.uk/viewtopic.php?f=1&t=119153&hilit=sky+echo+Charging It's long but don't skip this post in particular: https://forums.flyer.co.uk/viewtopic.php?p=1864496#p1864496

    My Carmo install goes through master switch and fuse to battery. I didnt pay attention to grounding the case as I assumed it was not actually electrically connected to any internal components but was merely a heatsink. Maybe I should go back on that? I suppose checking for continuity between the negative wire from the regu and the case would confirm whether or not grounding the case provides any purpose electrically for the carmo?

    There's a generation 5 Jabiru engine?. I hadn't heard that do you have any links to info?

    I think it looks awfull with the nosewheel, but the Taildragger looks quite nice. The one at my field is owned and flown by a quite small guy, I dont think you'd get an American sized person in one.

    It has a reduction drive.

    What tests checks did you actually make? and what where the symptoms of you're apparent failed regulator?, It looks like you never said what lead you to this conclusion.

    I see it has one of those industrial V twin conversions installed. In my view a much better option than the 1/2 VW. there is a Spacek SD1 fitted with one at my airfield and it seems reliable though it doesnt fly often as we are exposed to a lot of high winds and turbulence and the SD1 being a very small taildragger doesnt fare well.

    What a prat (nicest way I can think of putting it) He was lucky to get a bail extension, walking out of court without being granted leave to do so is a clear indication that he is a flight risk (flight as in running away from justice) I would have remanded him and depending on if he had been previously warned possibly held him in contempt.

    Sorry forgot tos say, you are looking for something like at least 28 volts ac coming from the alternator at 3500rpm and resistance across the 2 yellow wires of between 0.1 - 0.8 ohms. (this is from memory please check these figures they are in the manuals somewhere) Mine measured 30v ac at 3500rpm and 0.2 ohms

    While its unplugged check the Stator output, its an easy check

    I actually think this is a wise move, a way to keep making the small powerful engines they have so much experience in but where the market for ground based use is falling away. The aviation sector will be the last corner that ICEs will continue to dominate over electric

    Just had to do remove and refit the number 1 cylinder lower elbow after finding a leak there, bugger to remove due limited space, I've refitted it now with Loctite 577 which incidentally has a 10 hour cure time, so turned into a 2 day job. Hope it fixes the leak. facthunter they arent tapered threads, they are parallel M18 x 1mm and need to be screwed in till bottomed out then turned back to set them to the appropriate angle, hence the glue being a quite important part to get right. Im not a fan of this attachment method tbh

    I have done similar once when flying a Skyranger from the right hand seat practicing stalls my muscle memory from many hours in the left seat where the controls are opposite handed took over for an instant.

    Small ducted fans are very inefficient and though only used for a small portion of the flight the aircraft has to carry the weight of them all the time even when they dont provide any lift or thrust, add to that the compromised wing structure that will incur a further weight penalty and the mechanism to retract and extend the wing section and its just more snake oil.
  20. Underwood
    Well it has an alternator as standard (produces AC), but if you mean a car type alternator with a built in reg/rec then yes you can fit one.

    How long is the Warranty?

    Rotax 912 with Ducati Regulator/rectifier....normaly fitted with a light that comes on when the master switch is engaged and remains on till the engine's generator is producing sufficient voltage then goes off. on shutdown of the engine the ligght will come back on untill the master is turned off. A quick question to those who have the above with a capacitor across the regulators output, when you switch the master off, does the charge indicator light go off immediately or does it slowly fade out taking a second or 2?
  23. Underwood
    This has been in prototype for quite some time now which could be a good thing. It looks the business and a modern all metal light Bush capable Taildragger is very much needed imo. If I could afford one It would be right at the top of my list.

    That regulator seems like a waste of money to me. Firstly the claim to provide Anti Lock simply by placing a pressure limit is Bogus, It can only work for one specific combination of ground friction, tyre pressure and weight on wheel, anything outside of that one set of parameters and you are either going to lock the brake or not be able to exert maximum braking force. True anti lock that works in all situations needs a wheel speed sensor. Secondly the other feature of balancing both brake's pressure is a negative one if you want to lock one side to turn sharp. An odd contraption P.S. your symptoms could be the result of leaking internal piston seals, unusual for both to fail the same though unless the wrong brake fluid was used which can wreck some seals
