  1. Due to a mix up at Vans, I have a spare SB 18-02-02 Stabilator spar upgrade kit available. PM me if interested and I'll mail it out if you donate $10 to Ian for the site. Cheers rgmwa
  2. Oops! I should have said 2.3 times stronger and 3.3 times stiffer. Apologies all. However the difference is still significant given the small increase in thickness. Can’t go back and edit my previous post unfortunately.
  3. I don't know the answer, but compared to 1.0 mm sheet, 1.5 mm sheet will be about 3.3 times stronger in bending and 5 times stiffer.
  4. Took me a while, but here is a wartime report on the 109E. The canopy could be jettisoned (see Appendix 1). http://kurfurst.org/Tactical_trials/109E_UKtrials/Morgan.html
  5. I'll counter with this Kaz, although I think this aircraft is a G model, so you may be right about earlier marks. Third paragraph under `Entering the cockpit'. http://www.eaf51.org/newweb/Documenti/Storia/Flying_ 109_ENG.pdf Cheers rgmwa
  6. I believe the 109 canopy could also be jettisoned. Rear mounted springs lifted the back of the canopy into the slipstream allowing it to detach.
  7. Mine are Norbar. Bought from a supplier in the UK (cheaper than here). The 1/4" version goes down to 10 in.lb
  8. You will need one that goes down to 20 in.lb or less for most of your work (AN3 and AN4 bolts typically). A 1/4" drive torque wrench is ideal. For prop bolts I've got a 3/8" wrench that has a much higher range (can't recall what exactly).
  9. Only until Trump hears about this new high tech export initiative from China.
  10. The 120 kt sea level LSA limit applies in the USA, but not here. The Sling has twice the fuel capacity of the RV12, although full tanks, 2 people and baggage will put it over the 600kg LSA weight limit. That won’t matter if you build it as VH experimental since it’s designed to the VLA standard which allows 700kg AUW. If it’s going on the RAAus register, you will be limited to 600kg.
  11. That's plan B.
  12. Thanks Mark, I'll keep looking.
  13. Skyshop want $15 a tube and a minimum $20 order. Last time I bought some on-line (can't recall where from now) it was about $15 for 4 tubes. And no, it wasn't last century. I know $15 is small change in aircraft dollars, but it's just the principle of the thing.
  14. Anybody know where to get torque seal for a reasonable price?
  15. This guy used what looks like strips of black cloth. Good luck! https://www.youtube.com/watch?v=F-p-gy6NBFI
  16. Yes, there will be a lot of bi-axial bending and torsion on that connecting spar that would have been greatly reduced if they'd just connected the tails together, but no doubt they have good reasons for doing it the way they did.
  17. Volksplane
  18. No point. The poll result would be zero.
  19. I was 59 and pleased to admit to being a working younger person according to the criteria
  20. I comma but lately to this thread in good faith, but sadly leaveth, never to comma here again.
  21. Here's the story: Robert
  22. Antarctica: The Coldest, Driest Continent on Earth
  23. Maybe Ian could stock them at Clear Prop. I'd buy some if they're that good.
