Following a unplanned re-kit of my Airsail Auster, I'm looking for a plan in order to rebuild it. The wings got off likely, but the fuselage was basically match sticks forward of the trailing edge. Can anyone help?

The top two pushrods, linked to the linear servo, connect to the rudder and tail wheel. The bottom pushrod is the elevator. I did wonder if the two floating pushrods at the back of the cockpit were used to animate a pilot figure.

It seems obvious now you have said it, although it seems an overly complex mechanism to achieve it. I suspect the string/chord holding the bolt was once eleastic, but it is completely perished now.

I recently aquired a cheap 1:4.5 scale Tiger Moth on eBay as a project for a large sport flyer. I'm calling it vintage as the wings and tail surfaces are silk covered.
What was not immediately obvious in the eBay photos was that it doesn't have any Ailerons, so I'm trying to identify it to see if it is designed as a big rudder elevator model.
The lower wing is hinged in the middle and is held on with rubber bands. The dihedral with the wing bolted doesn't big enough for a RE model, but looks about scale. The rudder is often stated as the primary roll control on a Tiger Moth, so could be ok.
There is also a weird mechanism on the lower cente section which runs from a servo to a pin. I've traced the path of the mechanism in the photos with yellow arrows. Any ideas what this is for?

The listing described it as a "COX Queen Bee or QRC .049 glow engine". here is a photo.

Thanks for all your replies. In all my searching, I never came across Optifuel Benol Racing Castor Oil.

This is my first time posting here, so apologies if I'm treading old ground. I did a search and the only thread that comes close is "Techpower 5 v Optimax".
Since restarting the hobby, I have only flown electric. I recently came into possession of a Cox .049 Queen Bee and I though I'd put it in a vintage style airframe.
Researching the fuel requirements for this engine, It seems I need 20% to 30% nitro, and 20% lubricant of which, at least 10% must be castor (https://www.mh-aerotools.de/airfoils/documents/cox_049_operation_and_troubleshooting_guide.pdf)
Model Technics GN-25 or GX-25 would have been ideal, but is no longer available and I can't find direct alternative. I contacted Den's model supplies, as a seller of Cox engines and he recommended buying Big Bang 25% and adding 10% castor oil. The problem is that Model Technics Castorlube is out of stock everywhere is all can sizes.
So the question (finally), Does anyone:
1. Know where I can buy some castorlube.
2. Suggest and alternative brand of castor oil.
3. Suggest an alternative fuel that is available.

This is what is left if the fuselage.
Geoff. I could be interested, but it would have to be posted as I'm in Somerset. How much would you want for it?
Kevin. I'll reply to your pm. But want to post the photos here to refer to.
