  1. Bummer....I wonder what the issue was....maybe thats a project I need to look at in the future. We have the technology

    So how is your prototype coming along?

     

     

  2. Eightyknots. I hope you have some Devine intervention, or are ageless. If your current building rate of two hours every 3 months continues, your build will take 192.5 years! LOL. Perry.

    Don't listen to his harsh words Hank! I have only got about three hours in on mine in the last couple of years, after my brisk start. But we will get there, it isn't a race.

     

     

  3. Oh Marty I didnt make the body...I need to make the ring that goes inside the tank to clamp that body to the tank. Although I am sure I could come up with something similar but its a lot of work to do so....much easier to buy those parts :)

    If the ring is built as strong as the cap, how do you get the ring through the hole into the tank? does it have to be made in two pieces?

     

     

  4. An AP332 hub takes 60mm blades, like Bolly, and are rated upto 40Hp per blade, from memory. I was keen on Sensenich blades but ended up with Whirlwind Razor blades, both of which have a 70mm boss, hence the upgrade, but also came with a small weight penalty.

     

     

  5. I just had a look at the Chipper site. In the purchase page, they say Rotax 912 ULS - $11,900.Ok so the AUD is about 77 cents US, so that makes it $15,400ish.Where the hell does the other $10,000-odd come into it??

    It must be the Flood factor! The market is small and we are flooded with choice.

     

     

  6. I have used ANR headsets and have had no problem with cockpit noise except for one cross country during my training when I realised that I had not pressed the button to turn on the ANR for the first half hour. ANR is not nearly as effective as a passive headset when the electronics are not doing it's thing.

     

     

  7. Have any of the 200 buyers of the steel bungee ever weighed the new Viking bungee and compared the weight with the original Zenith bungee?If so, what are the weights?

    Hank is just beginning his Savannah S now so it will be interesting to see which way he goes, he has been following this development very closely for years. I have not considered this upgrade for two reasons. Firstly I have an Airmaster constant speed prop which adds a fair bit of weight in front of the nose leg already. I have also spent weeks working at Aerokits over several years, I would be wealthy if I had a hundred dollars for every time Reg has said "if you keep adding weight, it will never get off the ground". If the bungee was a total disaster there wouldn't be thousands of aircraft around the world still using them. They are relatively cheap, light and durable, so perfectly suited to affordable ultra light aircraft.

     

     

  8. Problem is a number of countries are mandating and going straight to full EV by 2050, petrol vehicles will be illegal in China then for example, so this will not likely come to fruition. Hybrid is a stop gap so I don't believe you will see anything more than basic 'normal' small engines powering gennies.Our smallish city will have 9000 public chargers fitted by 2020.

    You will need a couple of nuclear power power stations as well then!

     

     

  9. Had my first go at Alodine dipping today. Set up baths and rinse tanks. After de-burring I had a go at the rear fuselage frames. Pretty happy with the results, maybe a bit longer in the alodine.Had to rivet one frame together to feel like I had achieved something for all the effort.

    Did you Alodine the rivets too?

     

    Did you have a reason for riveting through the corner frames into the thin material of the wall frame? I would suggest putting the rivets through in the opposite direction, pulling against the holes in the heavier material always.

     

     

  10. Depends how long your body is, I have fitted a 6'9" bloke in the Savannah who had exactly the same clearance that I have at 6'3", which is about 1cm less than you describe. All you can do is pull the booster cushion out from under the seat. Have a look at one of the newer one with adjustable seats. I am not sure if they have more or less head clearance.
