  1. I have printed the drawings but they're illegible, too small to help. I can see the bearing, its drawn mounted on the bare leg. Looks like its pinned to the outer sleeve , would that be correct? How about the discs that proved the springing? what are they? I've got hard rubber bar from my Jodel u/c rebuild , Shore 70, it may be too hard. Thanks anyway. Cheers , Geoff
  2. I get motorcycle fork legs hard chromed all the time. No problems there. About $200 per leg! Leg is ground -chromed -ground.......... they're experts
  3. Working on a Gazelle, replacing the front tyre I pull the tail down and check the front leg. It wobbles a bit . the leg itself (the inner tube) was chromed that's now gone in places, there is up and down "slop" I read about biscuits in the manual , does not say what they are. How are the bearings in the outer leg arranged? Is it just a spring in a tube? Does anyone have a working drawing of the leg? Any help much appreciated. Thanks GWH
  4. We did that when building the engine mount!...to no avail. If the thrust line was out more than a couple of mm's the trim would require alteration shirley, plus the prop shaft would rub on the cowl.
  5. OK, so two years and $45000 later , We have a flying ( under a special temporary C of A. ) Rotax powered J160. Now approaching 40 hours of faultless operation. All within 50 miles of home! The aircraft is also deemed so unsafe as to not qualify for RAA insurance coverage , It was reported to me that " Examining Engineers" cant even be çertain that the thrust line is correct! (The elevator trim lever remains in the original position ) The aircraft is thus unregisterable under all present groups ( 24, 19 ect ) .... It appears that a major fault was not providing identities and details of similarly powered Jabirus. Plus wandering too far from the original spec. (Also a major sticking point. ) I did make appeals to people with Rotax/Jabs on here and other forums..... . But only a single photo or spec sheet was forthcoming. I had a couple of promises and some knockbacks. one positive result, not enough .... The RAA of course MUST know who built them and have photographic evidence. But they don't share. As things stand I CAN fly the Jab, within a 50 miles radius. Within a temp C of A ....But there are no circumstances or pathways to registration ATM. Thus flying further than I can see is not possible. To say I am disappointed would be the understatement of the century. at 77 years old 2 years is a big chunk. My immediate instinctive response is to burn the Jab and L2 cert. and walk away. It's unsaleable and I cant afford another. .... I am trying to find a positive. Not there yet..... Flying is still flying. The point of this all.? BEWARE OF MARAP. You can invest Lots Of Time and Money and have NO control.
  6. Just received this rather drastic email. Amber Aviation is the Lessor of Tooradin Airfield on the SE outskirts of Melbourne. What does the team think? is this the way to increase traffic or? Tooradin.doc
  7. after more than 60 years putting engines together I will ONLY use Yamaha Threebond ( I believe all Threebonds are the same) painty it on both surfaces, let it "go off" for 15minutes or so. No leaks, Ever. Loctite Master Gasket has failed me more than once. Never again. (Goes very hard and flakes off separated surfaces) Cheers.. G
  8. I just tried searching for Stolspeed.com on "Bing" "Google" "Firefox" on my phone and on my PC. all I get is "unable to access this site" There's something going on. I've been trying for a few weeks......I'll try someone else's pc...............G
  9. That really weird , I just get the standard blank page "we are having trouble finding that site" I'll try a different search engine.
  10. Does anyone know what has happened to the Stolspeed website? Or does anyone have a telephone number for the owner?
  11. Thankyou for your reply. As far as I can make out it IS type certified. with a special certificate of Airworthiness. However later down the pages I see ( note 1) a paragraph (which I attach.) declares that it pertains to serial numbers 29 thru 254. Mine is number 006. Could that be a straw?
  12. In the middle of our MARAP application, 5 months in, just about 20 hours on the beast. Flies like a Jabiru 160 with a bit more power. Cowling mods finished , Got the water and oil temps up to a reasonable level, Blanking off the top cowl openings seem to have given us about 5 knots, But that may be wishful thinking I cant really see where that could have come from ( better engine temps maybe) . Someone asked me why I hadn't just changed to E24 Reg. I couldnt give an exact answer, so looked it up in the technical manual online. Now I am more confused than ever. The Jab 160c is a certified aircraft. Needs Marap for modifications. OK , Doesn't actually say that But OK. . However Page 6.1 section 8 through 9 goes on to explain the process to having it E-LSA registered. Does anyone actually KNOW , according to the Tech manual , Why, when I have no intention or requirement to teach in the aircraft, have to go through this complex process. It's difficult to understand and I fear that I have bitten off more than I can chew. I'm close to walking away from it and the RAA.. Just too difficult to deal with... Cheers, G
  13. Its oK someone else is transporting the aircraft! I'm off the hook. But I had decided to go Via Temora , Narrabri, ( or similar ) Casino then up the coast and along the VFR corridor then along the Island VFR corridor turn left to Caboolture.
  14. In the planning stage now. Probably Saturday dep. BUT looking at the map around Brisbane, What a mess of Military and controlled airspace. How the hell does one find a way through that lot. We're looking at a route Tooradin-Wang-Temora-Narromine-Dalby-Caboolture. Over two days weather permitting. Can anyone tell us the best route to negotiate Controlled and Military airspace on the last leg.
  15. 3 point how many litres for 110hp? That's really not good enough. If fact it's not a lot different to a Continental 0-200....... So it's going to burn about the same as the 0-200. That's just sad. Why would a manufacturer bother. All they're doing is diluting the present market. Unless there's some magic property that I have missed or haven't heard of yet. 30 something hp per litre. wow. (in little letters) A postie bike puts out about 75 bhp per litre. They can't do better than that? Back to the Rotax....
  16. Thanks for the comments. I appreciate it. The water temp only gets above 80c with a full power climb to altitude. Oil temp is in the green but only just.  I can block the air intake off of course.  I have limited the air intake at the front of the cowl by 50% as that is only air for the cylinders and carbs. (carb temp is about 24c)  t I'm going to wait for summer before I make any other alterations. see what its like at 30c

      From the photo (on its side) showing cowling/air inlets it looks like you may have overdone the incoming air. What do the top/bottom scoops feed air to?

       

      On my last aircraft, ATEC Zephyr/912ULS, I restricted exit air during the cooler months. I just made up a very light weight aluminium plate that covered about 80% of the exit air hole. Probably went through 3-4 versions (started large & progressively reduced plate) until I was happy with all the temperatures.

       

      Yeh! In Australia we really need to focus on our long hot summers, with some sort of fairly easy winter flying temperature fix.

  17. Thank you everyone for the input. I don't like putting weight in the tail. But there was nothing to move. The aircraft weighs 6 kilos more than original and 2.5 of that is tail ballast. I could use a much heavier battery ( 12? kilos ) and place it behind the seat next to the fuel tank, then run much heavier cables next to the fuel tubing down the centre of the fuselage. That would be adding considerable lbs to the total weight..... If I did the job again I would put the engine and inch closer to the firewall and alter the cowling. If anybody needs the measurements I am quite happy to supply, The aircraft flies straight and level with the tailplane horizontal. It can also climb at a frightening angle. Not been solo yet, but I estimate 2000 ft per min to be a realistic number. it also runs a bit too cool, I could have used a smaller radiator, smaller air scoop and carried less water. Next time I'll know. Thanks again. Geoff
  18. I took your advice and found a J160 W&B sheet. It seems all may be well. What do you think? And thanks for the solid advice. G W & Balance sheet.pdf
  19. THis is true, The battery in question is LIFEP04 not lipo. The problem lies in normal battery weight 7 - 10 kgs. and the position available is some way behind the seats. That may be too much of a good thing!
  20. 400 grams a foot in front or behind the c of g will make no difference
  21. Battery is so light as to make no difference. I have necessary weight and balance sheets. (Attached here) I can see how to calculate aircraft index units. But I want to know how to calculate backwards so to speak , or how to achieve lower Aircraft Index Units by a known amount. For example ; adding 1 kilo to arm at -3750mm (tail) moves C of G rearwards by ? mm. I'm not a maths expert. I can guess, but I want to KNOW. Cheers weight 1.pdf Weight 2.pdf
  22. Now my Jabiru / Rotax project is nearing completion there is a matter I would like to correct. That is the C of G. placement. Jabiru say that the forward limit of a (at MTOW) J160 should be 233mm behind the wing L.E. After I had the weight and balance done I see that the C of G is at 217mm behind the L.E. the question is How much weight do I add at the tail end to move the C of G 30mm rearward. I have all the calculation values at hand , I just dont know how to calculate the value. Weight 2.pdf weight 1.pdf
