  1. Sorry Ian, don't like it.

     

    No need to follow modern trends (they will come back anyway), it's aimed at facebook and related rubbish to show mugshots, half of us have our planes instead.

     

    Planes fit in square holes......

  2. Anybody been looking/thinking about the Kempsey 'Airshow' 1st/2nd October?

     

    Was planning on wandering up from Taree, so had a look at the webpage for arrival/departure and program closure times;

     

    Attractions - Wings over Macleay

     

    Then started looking into entry prices;

     

    Tickets - Wings over Macleay

     

    And had second thoughts.

     

    After a lot of digging I found the arrival/departure times;

     

    Getting There - Wings over Macleay

     

    So looks like I'm just going to have a normal day flying around Taree.

     

     

  3. Yeah, the irony.

     

    You can buy a finished almost ready to fly model, cheaper than you can buy the balsa to make it!

     

    Although HobbyKing isn't always as cheap as you think, I just wanted 2 roll of solarfilm, and they had a good price ~$12 a roll, but with postage it was going to cost over $44 in total!!

     

    Almost cheaper to order another model, and get the solarfilm squeezed into the model box?!

     

    I thought only Hong Kong ripped you off with postage?

     

     

  4. I guess the 'gull wing' gives you that bit of being different, but a structure still needs to be 'arranged' correctly.

     

    To that end, the inner lightening holes are in the wrong place.

     

    Usually they would run along the centreline of the beam, as that is the neutral point along the shear plane.

     

    Technically, as sheet structures will resist tensile loads better than compressive loads, the lightening holes would more correctly taper down towards the lower cap, keeping more material in the compressive area of the shear web.

     

    Just saying...

     

     

  5. You need to be careful with some of these 'scaled warbirds'.

     

    As a sideline, I looked into what people wanted, SPITFIRE ! was the usual answer, so Sullivan supplied.

     

    Almost immediately they cried, 'Can you make it a two seater?!'

     

    Idiots, I thought to myself, surprised they didn't want tricycle undercarriage!but that's the way it went;

     

    Two seat Sullivan Spitfires,

     

    Two seat Titan Mustangs,

     

    Two seat Flying Legends Hurricane, and so on.

     

    I got to thinking, if they want two seat warbirds, build warbird trainers!

     

    I started tossing up between the Chipmunk, and the Ryan STM.

     

    Then the company at Bankstown I worked for, got to restore a Ryan!

     

    (Here's where my first sentence comes in....)

     

    I quickly found out that I, at only six foot, could not fit in the front seat of the Ryan, and could barely fit in the back!!

     

    I think a good scale Ryan STM would be about 110%!

     

    I then started looking at the AT-6 Harvard, as we worked on them as well, and it actually scaled nicely.

     

    Initially drawn to have a 912 up front, the Rotec fitted as well...

     

    Not long after I started some drawings, the Flying Legends Tucano appeared on the scene.

     

    Inspired by Bryan Gabriel, I looked into a small single seat scaled PC-9, with a 582 up front.

     

    Since them I've had a few people interested in the PC-9, but a bit bigger, as a two seater.

     

    The scribbles continue...

  6. As mentioned, the 6000 series is more workable than the 2000 series, even at T6 temper.

     

    If you look closely at a Spitfire, it's not unusual to see the odd wrinkle and buckle, they were built quick.

     

    The usual trick for 'compound' shapes is to do 'steps' between bulkheads, if you sight along the skins, this becomes apparent.

     

    Have a look at a Sullivan Spitfire for some ideas, he solved most of them.

     

    In stressed areas like the wing skins, using the multiple skin join steps, requires a bit of thought about number of rivets at the joins.

     

    A lot of it depends on how complex you're willing to get...

  7. All these things have been worked on, no promise that I've solved all of them yet, but basically as you've said.

     

    Aircraft originally designed around a 912s, but there is an EA81 Subaru sitting there at the moment, so the wings may yet get swept.

     

    I am looking at an extension shaft for the Subi reduction system, ie, an extension between the block and the reduction system.

     

    Am toying with the idea of tall skinny radiator as the trailing edge of the pylon.

     

    Will never be able to get rid of the 'pusher' sound, but working on it.

     

     

  8. Sorry Bill, didn't see this post earlier.

     

    Yes, I've dealt with them on a few occasions, got some drums of dope waiting for me to recover my Lightwing as we speak.

     

    I've been getting non-tautening Nitrate and Butyrate dopes from them.

     

    Previously I was using Polyfibre adhesive, but this time I have a drum of their fabric adhesive, but haven't tried yet.

     

    Don't expect a problem...

     

    We need people to support them, so they keep making these products.
