Auster mk5

Tony have a look at the DB Sport n Scale wing retention system if you don't mind a small hole under the wing close to the fuse. I got some at a show for my CAP Tiggie when I get roundtuit. Must say I feel like Alan does about the magnets, but hey it's your model mate.

wing plan nearly ready i think.


going to be a largish model isn't it.


not going to use magnets gents, just not sure which other method to use at the mo.
i will get the wings built first and then worry about it.

looking at ways to hide the servo's and control horns in the wing now.

ya dont say

I have to agree with Tony.
On a high wing with load bearing bracing any negative g load and the struts will tend to push the wing off the rods.
Technically the rods aren't required at all. It only needs two bolts for each wing.

There is no spar structure across the cabin roof.

Well done on finding that, ive looked everywhere for that sort of thing, thing is, that will all be welded steel, tubing, Tonys efforts with the tube will keep it alls safe, and not put strain on the cabane

been reading some airsail builds on line, they use u brackets on the cabane and bolts down through the 2 main spars to hold the wing on.
the spars and braced with steel between the first and second ribs only, so my tubes running through the first 3 ribs could actually be stronger than their method ? maybe.

I still believe that the tubes and strut arrangement alone will be sufficient for Tony's needs. I have a Laser 75 powered 86" span Storch (professionally built but yet to fly) that I acquired about five years ago. The wings are held on in a similar manner and I'm confident it'll be sufficient. Neither Tony nor I intend to put any negative G on our respective machines, so the flight loads will keep the wings in place.In any event, were the wings to be subject to negative G, here is little chance that they would do anything but move on the holding dowels by a very small amount, and I doubt that they would even do that. I firmly believe that even such a circumstance would have little effect on the flying qualities or handling characteristics of the aircraft.

I'm confused Alan. what do you mean by the word 'cabane'?

noun Aeronautics .
a mastlike structure on some early airplanes, used for supporting the wing.
Origin:

Tony's Barnstormer has cabane struts!

I think your interpretation of the definition is flawed Alan, there is no cabane on an Auster.

sorry, its just something i have always called the pats that support the wing mounting, but then, i think you knew that, and are all nitpicking,

i call it the cabane as well, sorry.
what should i call it then.

i call anything that holds the wings on a cabane structure Tony, and i dont really give toss
