    Onetrack, I agree with you, it does look flimsy. That thin tube holding the tail assembly might be steel of course. Others have done the same on aircraft but they usually have a support beam going under the prop and then up to join the main boom. Pylon500, nice to see you posting again. You seem to have been away for a long time, or I haven't been reading threads on which you have posted. Anyway, thanks for the drawing, very simple, very neat. Somehow, I doubt that it could be kept to 95:10 specs though.

    Hmmm, not sure that I like it. Why didn't you keep the trailing edge on the same angle as the rest of the wing. I realize that you've got more area to help prevent to wing-tip stall but..........

    Nice one AF, with no pulses as from an ICE, I "guess" there won't be TV problems.

    OK guys, so I got the title wrong, still a terrific achievement and 'apparently' very easy to fly. There is a second 'on board' video on his page.

    Rotax, you seem to have missed my point. My engine, hub and propeller are not in contact with the boom what-so -ever. Therefore, whilst your assertions are correct for the commonly accepted method of co-axial props is correct, it is not so with mine. No engine vibrations can reach to boom, nor can prop influences other than airflow over the tail surfaces. If it was legal, I would put contra-rotating props on to reduce swirl effect as well.

    Rubbish! It just has to engineered right. The normal way people think if doing this is to have bearings on the boom itself and this leads to problems like torsional vibrations. My system leaves the boom completely from of contact with the prop assembly. For AF's info, I've been re-looking at my bearings today to provide fore and aft thrust restraint. Now I'm not an engineer but I think something like this would work. Whilst not modeled, tho outer bearings are mounted to the airframe in a 2 part cage (top and bottom assemblies). The hub & propeller assembly is trapped between the 12 bearings. The boom and tail assembly slides in through the hub (with about 5mm clearance all round) and is fixed directly to the airframe and should behave as any other boom type design. Control rods run through the tube and have no direct linkage to the airframe part of the control system. How? don't ask, it's all in my head. Your probably thinking something like "does he think he knows more than a certified engineer", well know, I don't, but I do as my signature says, and think outside the box. Actually I'm going to change that to sphere as I think in true 3D,. all around. It will be most interesting to hear/read comments when I publish my morphing control surfaces. Now that's a really interesting subject.

    Of course it can fly, but only vertically, and in a dive.

    G'day AF, nice to see my design is still intriguing someone other than myself, not that I've worked on it for several years now. I've just had a look at my SU model and can't find an answer for you re thrust bearings. I imagine the easiest way to do it would be to lean the bearings on a 45% face, both for and aft. That would lock the hub longitudinally and axially. The bearing cage is fixed to the airframe. The tail boom assembly can be slipped out from the airframe by itself leaving plenty of access to the prop and hub assemblies. I may get back to this design after I've finished restoring my Thruster.

    Not sure where this should go so move if necessary mods. Swedish DIY Hobbyist Builds Personal Flying Machine For 10,000 Dollars

    A few new images of my rebuild. Seat and cover hacked to fit lower and around control stick. Playing with a cardboard instrument panel. Still need to make a new c/stick, this one was intended to fit under the seat. New 3D printed tank mounts, I modeled on SketchUp and had them printed courtesy of my local library. 4 off, solid, $8.00 the lot. To think I was originally going to have them machined from alloy billet. Before you ask, we used the hard stuff that Leggo is made from. Very tough. I will be putting bolts through them later, but only on the bottom rails.

    Thanks Scott, I'll just delete the links.

    the files still exist, downloaded them yesterday but can't get them to load into GE.

    A public airshow and no ambulance!!! Can't believe it.

    Good evening everyone Syan dubh flew ??? Some information??
  15. Deskpilot
    Thanks Kev, should have looked at my rudder which has the cables and bungee's attached. I somehow got the thought into my head that the cables would run forward and join onto the main rudder cables. Another mystery solved.

    Thanks Kev

    Can anyone provide me with photos and /or drawings of how a Thruster(T84) tail wheel is set up and controlled?
  18. Deskpilot
    May I suggest, even request, that we get back to the topic of this thread, please.
  19. Deskpilot
    I was taught to always be in front of the aircraft, even more likely to bite you. I don't get the connection with your first comment.
  20. Deskpilot
    I learnt to fly IN a Jabiru LSA55. The only things I can think of which you fly ON are a broomstick (for those so inclined) and a trapeese. Sorry for being so critical.
  21. Deskpilot
    Oops, my mistake. Should read a bit slower.

    And where are you going to find the Visa engine Bruce. Probably as rare as hens teeth here in Australia. I've often thought of using the GA boxer engine but even they are getting rare nowadays.
  23. Deskpilot
    Can/has his plane be/been fitted with an autopilot? If so, even I could do it.
  24. Deskpilot
    Oh Bex, that's fighting talk from a South Australian. Be careful my friend, be careful. Welcome SLB, what do you fly and from where?

    That young lady deserves a spanking. Did you see what she did wrong. Take another look (you bloody perverts haha) In her other videos, one sits there watching, and waiting, and hoping for a nipple to pop out. BTW, I'm first in line to spank her. Got it. Hmmm, perhaps that should be, Go tit.
