  1. I used Solaguard on old perished skins and the result was really good. Looked like new and now protected somewhat from UV.
  2. The good quality exterior water based house paintss work well on Dacron fabric. Stick well and are very flexible. Clean the fabric first with spraying thinners. Sounds vicious but doesnt hurt the Dacron at all.
  3. I use the vertical compass already in my Garmin GPS when displaying the HSI page. Works really well and easy to read and not influenced by magnetic effects. Another benefit is that it shows actual track made good, compensating for drift. I use it nearly all the time.
  4. Could I please get some more info from you JG? Any recommended brand / type, mixing ratio etc. I want to paint the plane hopefully this summer. Probably white with blue trim. I don't have details about brands and ratio of hardener. I just go to a good paint shop that supplies the automotive respray market, and tell them what I need to do, and they should know the best combo. They tend to be experienced professionals as distinct from those that supply the domestic market.
  5. Automotive enamel with hardener added. Sticks well, covers well, light weight, good gloss with hardener, easy to touchup, low cost. Fairly impervious to fuel with hardener added.
  6. 1800hrs over 16 years. All recreational, no commercial training.
  7. That's not static; it's 5800rpm wide open throttle straight and level, just as Rotax recommended and their charts are based on. That puts me at 5200rpm at 60kts best climb, and 5100rpm for best cruise right at the top of the Rotax torque curve between 5000 and 5200rpm. Not pitched fine at all, just correct by Rotax recommendation. I found static to be not a consistent base line for props comparison due to cavitation and whatever effects at no airspeed, straight and level far more consistent. Fuel consumption at WOT straight and level is 26 litres/hr.
  8. JG3 you have a few errors ! TECHNICAL DATA FROM THE ROTAX BOOK max continuous performance : 69kW at 5500 RPM. fuel consumption at max continuous performance : 25 litres per hour. **** specific consumption at max continuous performance is 286g/kW/hour **** premium ULP caloric value ~ 46 MJ/kg, so translates to 13.15MJ/kW/hour, efficiency about 3600/13150 = ~ 27% probably +/- 7 % depending on how you value the weight of the fuel, the calorific value of that specific fuel etc Yes, I realize that Rotax publishes 25 litres/hr, but I do not get
  9. I do need to step in here and try once again to clear up some misunderstandings that are being tossed around. First of all, if an aircraft is pitched to 5500rpm wide open throttle (WOT) straight and level, then 5500 is no longer max continuous, not at all, it's now wide open throttle full power and is limited to 5 minutes! I guess I need to try to explain that.... The max continuous specification for an engine is not governed by the revs but rather by the amount of power being generated. That max continuous power is limited by the ability of the internals of the engine
  10. Wandoan, Qld airstrip 17 Aug 21.
  11. I sure wish that I could delete those old ads that have sold months ago. Surely it's not that hard to make it that clicking 'Complete' could delete the ad. I won't be adding more ads until I can delete when I want to.
  12. It's easy enough to post the ads. Surely we should be able to delete when we wish to. Could be made possible under the 'Edit' function.
  13. I have found the Classified section to be very useful for selling items and has potential for much more. Is there any way to delete those items that have long since been sold and now labelled 'Completed' or 'Expired'?? They clutter up the list and make scrolling tedious......
  14. Please do let us know what works the best, if anything.....
  15. Try WD40, that works for doubles-sided tape residue.
