    Concepts only: Doodles without numbers

    What you second gif is not showing is how elevator movement interacts with the aileron circuit. As you move the elevator fore or aft from neutral, it will pull on both aileron links, making both ailerons travel upwards (some gliders [Ka6] do this deliberately which ads washout as you flare or...

    The hot mess of aviation magazines because of Firecrown

    'These questions might affect his ability to sell the ship' Therein lies an odd (cultural?) mindset. If you build something, my take is that you want to fly it, but unless you're building a prototype with the later intention of production and sales, then I wonder why the thought of saleability...

    Those Were the Days!

    My father (1930~1994) said that after WW2 in Australia, you could by a Tiger Moth for £50, as is where is, and for another £10 you could get a full servicing and full tank of fuel to fly away. 'Course at the time he was probably earning something like 7shillings and 3pence a week, so about two...

    Boom boom boom boom

    Got to wonder about the tailplane deflection :oops: Not sure if it has flaps (didn't look to be using them), but they will require more deflection of the tail, and I wonder how far it goes before you stall the tail? Might be a good idea to have some small canards? Still, I'm only an amateur...

    What did you do on your airplane project today?

    I think everyone that knows me would rather I machine than sing...:eek: Oh, and I've got two left feet.

    What did you do on your airplane project today?

    So, with the change to a taildragger on the group PC-9/Winjeel build, we're having to replace a couple of ribs on the centre section to carry the U/C. Also wanted to beef these ribs up a bit, so thought I'd put stiffening beads in them, but the Jenny wheel was a little small (read, would...

    Aviation related music.

    MANY years ago, there was a video on YouTube that someone made with a flight sim program, that depicted a high performance glider doing (somewhat unbelievable) aerobatics from an equally unbelievable altitude, culminating in a landing on an airstrip somewhere. The music dubbed onto it was...

    What did you do on your airplane project today?

    We did look at the Trojan, and the Mentor. Both have the same wing problem, being dihedralled in the middle, which make taking the wings off very awkward (I know that is not 100% correct, but a 'carry through' is actually worse), then there's the retracts, and the final clincher that neither of...

    What did you do on your airplane project today?

    OK folks, I've come to some sort of a crossroads. Many will know I've been involved with building four, 80% scale PC-9 replicas, started back in May 2016. It was going to have all the bells and whistles; retracts, variable prop, glass screens and we were looking at the latest Yamaha motors. We...

    Formula-I?

    I was more the dreamer type. I'm not really the organisational type. My plan was make the plane and just show up to airshows/flyins, do some fast passes and hopefully inspire people to do likewise. Sort of like 'organisation by accident' (OK, didn't want to use that word but...), as mentioned, I...

    Formula-I?

    Yeah, my 500cc class sort of faded into oblivion (can't even find my pages of re-written Formula 1 rules), and now that the Rotax 503 is disappearing, maybe the Yamaha class is more likely. Still, I tried. Yeah, I know, I'm wearing this picture out.

    Aviation Hoarding

    Thirty odd years of collecting 'this'll come in handy one day' stuff, but for the last ten years it's been going the other way, I'm actually using some of it! But yeah, I've got hoard stuff; Hey, I just like props ok? Note the empty screws where I actually took one down to use... I think half...

    May have bitten off more than I can chew - oops

    Being a 'project', I assume it may not have 'finish' (gelcoat or paint) on it which means you can look at the resin itself and determine if it's degrading or not. Scrape at it with a fingernail, and if powdered or crumbly material comes off, you might have a problem. If it's gelcoated (parts out...

    Just a couple of air to airs, not great photography, but planes you won't get to see too often... First is an early production AAK (Australian Aircraft Kits) Hornet, with a Rotec Radial engine. It has a 'robust' look that grows on you. (I didn't take the shot, as I was flying it) Separated by...
