    Aeropup

    I've watched the Aeropup fly at airshows and with many private owners in Australia for many, many years. A lovely flying aircraft. I even produced a cowling for a Rotax 914 powered one. What a rocket ship! Aircraft businesses take time to get started due to the time it takes to make demo...

    MOSAIC Rule Change

    Yes, we could do something with an extra 100 Lbs in Part 103. Add another 100 Lbs for a 2 seater. Bigger, faster, more expensive is going to kill light aviation!

    Sorry to hear that Dave. I hope all goes well from here!

    To what out-of-production aircraft would you buy the rights, if you wanted to start a 'kit-plane' company?

    Long-Eze is a rocket. I saw someone was plastic printing a mold for it! Going to use the big Rotax.

    Hi Al m, I own the Rigths to the Australian Sadler Vampire SV-2 and the 2 seater. Contact me on [email protected] if you are interested. Ray

    Crashes in the News - Thread

    I had a similar experience. I was in circuit at Waikerie, in South Australia and I saw an aircraft coming straight at me. I could not believe it when it had 2 big round intakes on its wings. The pilot of the Canberra bomber waved at me as he went by under me! Turned out to be the RAAF had...

    MOGAS in Fiberglass Fuel Tanks

    I have been making and repairing fuel and chemical tanks that are still in use 40 plus years. I use Derekane Vinylester with different numbers depending on the amount of chemical resistance needed. Methanol tanks need the 520 series but avgas can be done with 411 or 420 series. The real trick is...

    Flying cars

    The blokes in Australia that do electric conversions of production motor vehicles got in to trouble with the weight of the vehicles being more than the weight of the production vehicles. A mate of mine converted a Porsche 911 had to leave some batteries out to get it passed rego. Some of the...

    Flying cars

    Like I said previously, it is easier to get the car to fly than to get through the car registration process. The glass front windscreen can't be changed for plastic and get it registered. I even tried glass vapour deposited on both sides of the plastic but still could not get it through! At...

    Flying cars

    I think a good concept of flying car should have advantages for both the flying and driving vehicle (not the worst parts of an aircraft and a car). For instance; the road wheels could be used to accelerate the vehicle up to take-off speed to shorten the take-off distance. If the propeller does...

    Oceangate Sub Construction Details and Implosion

    I wonder why they didn't wrap the ti ends into the CF matrix rather than edge bonding. Seems like a real failure point to me!

    Plans built composite aircraft

    Cherry BX-2 may be an idea. Already quite a few of them in Europe with BMW/ Take-off engine/ gearbox combination. Ray

    Oceangate Sub Construction Details and Implosion

    Large difference in stiffness and Coefficient of thermal expansion/ contraction between CF and Ti! Straight sided cylinder for CF- terrible idea.

    Here we go...Synergy still NO FLY and lighter...

    There seems to be a huge pool of investors who would like to be associated with the "next big thing". A good time for "promoters of dreams" and computer renderers to get some funding. The engineers and builders are still living on peanut butter sandwiches as their ideas struggle to reality.

    Still breathing!

    Hi Autopilot, My Dad had kidney stones and that is the one thing that I hope I have not inherited from him! Are they going to blast it with sound vibrations? All the Best, I hope you pass it quickly.

    SGS 1-26 redesign as an ultralight motor glider

    What ever happened to the SparrowHawk tooling? Is it laying about on airport up in Oregon?

    Design at new version of the Fournier Motor Glider

    Hi Topaz, Do you really need 15 meter wings for a motorglider? I used to joke with passengers in my Grob 109 about "what glider would they like to simulate flying?". I could go from IS28 to SB29 with the position of the throttle! You could do a "touring motorglider" with the shorter wings and...

    Still breathing!

    Yes, the most poignant footage from the lockdown in Sydney is when 4 burly policemen arrested two little old ladies that were sitting on a park bench in the sun at the beach side. The way they manhandled those old ladies was way over what the situation warranted! Give some people power.......

    German Experimental Aircraft of World War II #13

    I found my copy many years ago in a used book store! I wasn't really interested in flying wings back then but have done some investigations and found that flying wings are not really any advantage in sub-sonic, low speed aircraft. The Akafleig SB-13 hasn't won a whole heap of gliding...
