    Yeah my only experience with electric trim is the golf, which is generally full up. For me I need it one led down from that. That's not much more up.

    Right you are. I might have been thinking of a flat spin for power. Bear in mind I've never done one. I've thought about going up in a glider to do some spin training. Tonight I'll watch some training videos on spins to get my head right. About what I said about trim. I was probably being a bit perfunctory there about the procedure with the golf. I'm translating my muscle memory into words! First thing is close the throttle to idle, and the nose will drop. As you do this hold the trim up button. It takes a number of seconds so you should do it pretty much straight after shutting the throttle. Personally the main reason I don't like electric trim is this adjusting via 'timing' rather than by position. Especially planes like mine or the Savage Cub, you just push the trim lever instantly to the approximate position, then of course fine tune it by feel. And now you mention it, yes two flap motors would not be a good idea. Which still leads some of us to ask- why electric? My theory is it's easier to bolt an electric motor where you need and run electrical cables however you like, than to maybe have to design around some awkward geometry for control cables etc. Mind you, again looking at my plane, the trim is push/pull via Bowden cables so geometry isn't critical.

    Dunno. The Tecnam Golf has a roughly similar layout to the PA 28 warrior. As far as I could tell, the warrior basically had a 'handbrake' bolted directly to the rod connecting the two flaps. Or looking at my own plane, the 'handbrake' pulls on a couple of bellcranks going to each flap. I can't see how using an electric motor, with a gearbox plus the wiring could be lighter. Of course maybe it's easier because of dihedral on the golf - just use two motors. But that sounds like even more weight. Thinking on this accident, again this is on the golf, I haven't flown the p92, when you close the throttle to descend before turning base, you put in full up trim to slow to descent speed. So if the trim 'ran away' it can only go pretty much one direction which is in the direction of higher speed/over shooting. On reflection doesn't seem like a runaway trim would cause a spin in this situation. Am i thinking about this correctly?

    Could be because I was converting from GA he demonstrated it? I didn't find it very alarming as others have alluded to. Stalls were scarier. Perhaps he was just showing me the very first signs? I remember the main thing to watch is that a spiral dive has increasing speed whereas a spin (I've never been in a spin, just from what I've been taught) has a decreased or negligible airspeed. Dive- close throttle, level wings, gently pull back. spin- open throttle, level wings, opposite rudder, release pressure on stick etc

    Well we did them. Spins aren't allowed in ra Aus. I don't think they prohibit spiral dives.
  7. danny_galaga
    Still do. I did spiral dives with Dave.

    In regards insurance and politics, perhaps we could continue that discussion in a new thread?

    Thanks recpilot, I thought that was the case. It should be noted that Dave regularly flew a number of different aircraft at the same airfield other than the Tecnam Golf. In the school itself an Aeroprakt Foxbat. But also a Tiger Moth, Gypsy Moth and when the flying school had it, an Aeronca Champ. My first taste of a TD was with Dave in the Champ. I'm sure he was flying other aircraft too, but these I know for sure. I guess I feel it's worth mentioning so people know he was in constant familiarity with a number of aircraft with different 'personalities' , not just the Golf.
  13. danny_galaga
    Again, take this with a grain of salt, but I believe Armin had purchased the plane, and was going to lease it to the flying school. I was to be flying it to get back up.to speed with TD. Seems to me that Dave was giving him a 'type' rating for that plane. In any case getting him familiar with it. I feel that's the general situation. But I don't know who ferried the plane from NSW. So the reverse could have been the case too if Armin was the seller and had ferried it , and then doing a few circuits with Dave to familiarise.
  14. danny_galaga
    Dave was flying tecnams every day. But I don't know about the other pilot.
  15. danny_galaga
    Names officially released now. The second pilot was Armin Sickinger.

    This accident hits close to home for me. One of the deceased is Dave Briffa, an instructor. I talked to him the day before. I was going to go for a fly with him because the wind was a bit tricky and I hadn't flown for a little while. I didn't end up flying though. I was also going to have some tail dragger refresher flights in that P92 once it was online. He was a good person and a great instructor. We always joked about how long it was taking me to build my plane. He almost always had a smile and was always interested to know what was going on with you. It's going to be strange for me to not see him at the hangar.

    Yes, repainted..same plane https://3.bp.blogspot.com/-wde9TWvUr-M/XcXtBykKn4I/AAAAAAAANTw/F5iHK74V_A0d4W1oZaIixCuZi1brVTpRgCLcBGAsYHQ/s1600/248357.jpg

    Take it with a grain of salt but ultimate aero were getting a Tecnam tail dragger. This may be the very one https://commons.m.wikimedia.org/wiki/File:TECNAM_P92_Tail_Dragger_(24-8357)_parked_in_the_general_aviation_area_at_Wagga_Wagga_Airport.jpg

    Was there yesterday. I have grave fears for someone I know there. I didn't notice that aircraft yesterday.
  21. danny_galaga
    Good point! I already first tested my skyecho on my phone 😄 Mind you, you can't even fly 60 minutes at 100km/h in these things before you have to return so navigation will probably not be much of an issue!
  22. danny_galaga
    Sorry to hijack, but I am entertaining the idea (My original plan actually) of getting a part 103 ultralight. While I'll just be pootling around in it and probably not navigating, would a sky echo still be worthwhile? I assume if I have that and nothing else, then at least it makes ME more visible? And obviously, with that sort of ultralight, I'd best be making a mount similar to bluesadventures, else it just winds up in the landscape below 😄

    So keep an eye out for HR station wagons is what you are saying?
  24. danny_galaga
    Sorry I thought it went without saying that you are replacing each pair of bushes with a block. I think there's 4 pairs of bushes in your photo? So 4 blocks. Instead of washers you would sandwich the 'outside' bushes with a strip of metal 250 X 50. It all adds up to just more of what you wanted (vibration absorption) in the same space. Did you say that mounting system was lasting 30 hours or something? With all that extra rubber sandwiched in there, maybe it could make it to the 100 hour mark...
  25. danny_galaga
    Hence why I thought instead of those bushes, which obviously must have been thought to be at least nominally ok, you replace the bushes with a block. You would at least have more longitudinal rigidity without having to change anything else. I'm not sure people are picturing what I mean so I'll give an example. PLEASE these are just numbers for an example. Say you have a mount like yours. With 4x rubber bushes of dimensions 50mm diameter and 25mm thick. The distance between the bolts is 200mm. Instead of those bushes, you have a 'block' of rubber that is 250mm long, 50mm wide and 25mm deep. That seems to me that it would have more rigidity than the 50mm bushes. I'm not saying it's the solution, but you also haven't said anything I didn't already know. The blocks must surely be somewhat better than the bushes, which remember are considered ok else no one would fly with that setup. Again I don't know that it's the answer, but an improvement on something already being accepted, whilst not having to change anything else.
