The devil will be in the detail ... like the new car200.002 from part149 “ (2) The requirement is that the aeroplane has been certificated by the relevant organisation as meeting the requirements set out in the manual prepared by the relevant organisation and approved by CASA, and as in force from time to time, that contains: (a) airworthiness, design and maintenance standards; and (b) aeronautical practices, test procedures and processes.” So there is the basis for 95.10 aircraft being regulated and tested exactly the same as a factory built and tested airframe if RAAus and CASA want to.

Had the same tacho response when I changed the 912 out on my trike years ago - old engine into flydat was perfect, new engine went from 2000rpm to full flip at 2001rpm. its just a rotax thing - their long held rep for quality can be a bit iffy on electrics.

The problem with a name-and-shame page and an honesty box is how do you know that nothing was put in? Short of the box being empty before and after you risk naming and shaming when there is no shame to be given out. And exactly the same as you in the airfield I used in the UK was funded by hangar/club member fees and landing fees on an honesty box when the canteen was closed. its a fact of life that there are people who do not act fairly and so long as they are the minority its more of an aggravation than a real problem

I wouldn’t do fabric over perforated. You’ll save very little weight but add heaps of cost and time to the build. You will get a better surface finish for less cost and time by just leaving it solid metal

I miss most jokes. It’s a feature. As for leading edges on ws theee is usually the leading edge fabric - very heavy because it’s a structural element in the wing that’s holding the curve in the leading edge tube then a light weight pocket sleeve and in the sleeve is slipped the leading edge stiffener - usually Mylar or fibreglass. There is a lot of design and structure at the leading edge of a ws wing

I live to bamboozle. Hints. The two seater in the first unidentified of mine is a factory built from France. Great climb ability - I raced one from a small field in Loire valley - his 912 vs my 912 in a WS trike - he kept up with me and not many three axis can.

Was short hand for 4 to 5 oz. And that’s light weight. Most coloured Dacron sailcloth eg contender coloured - is 4oz / sailmakers yard White plain weave I’ve used in thruster, flightstar and a couple of others I made sails for were either 4 or 4.4oz. The leading edges on the weight shift sails I’ve made are all 8oz with a 4oz outer colour sleeve. And for clarification a sailmakers yard is not 9ft^2 but 36”x28.5” So doing a bit of conversion 4oz Dacron weighs around 172g/m^2

Dacron/polyester may ONLY be plain weave BUT 1. It’s stretch in warp/weft are well known and VERY much less than nylon spinnaker fabric. 2. It’s cost in white in 4-5oz is equal or less then nylon ... colours are generally around 50% more than white unless you buy the entire roll 3. UV stability well known and very good Sorry but if nylon was actually well suited to hard work you’d have seen them rolled out in the mainsails decades ago - it has not because higher load is not well handked by it due to stretch and deformation from the required cut and in aircraft use the limited stretch and retaining shape wins hands down. Polyester wins unless you have the money for a laminate ... and even there laminated for yachts are often not well suited to aircraft because they have accepted increased cost and stability over UV life. Trilam is a good laminate if you can get it ... and it’s polyester core with clear laminate overlay.

Nope. :-). This one and the one I posted earlier will hopefully keep you all stumped for a while.

Thought of the Mouette but couldn’t remember the trike. In addition to the pusher three axis I posted try this one

Looks like T-bird ultralight on skis.

You have me with that one. It’s a trike and one I do not recall ever seeing before.

Looks like a Luciolle - Michel Colomban MC-30

Mine was copied from aircraft spruce who sell materials kits for it and I remember reading about its development when it first came into the scene

Well... “Everything about the Culp Special was meant to bring about that 1930’s airshow airplane feeling. Working with Hale Wallace of Steen Aerolab, Steve Culp redesigned the Skybolt and developed the modifications necessary for this round engine aircraft.“ So I think I got it first time

Or is it a culp special?

Are you sure? This is a steen skybolt with an m14 I found online after you said no ... and it looks a lot like the one in your pic

Let’s assume it’s a skybolt so it’s my turn

Well it looks like a Steen Skybolt with an M14 engine. If that’s it then bugger that one would go well.

Aventura or maybe a bucaneer You’re working through manufacturers at the top of the alphabet so searey is not an option ... even if the wing had been above the fuselage on a pylon.

Come on Red - it’s a bit like the flying biscuit tin and it’s detivatives - there are so many cub and super cub copies/modifications/inspired it’s near impossible to id the exact one.

Too easy. Airspeed courier

Lycra? Well that’s a kinky choice - leopard print by any chance? Probably meant to say Dacron

Well I’ve seen it before and it’s not a sparrowhawk so give me an hour and a cup of coffee to think. Got it. Chiltern DW1
