Hi Peter, I like that wing fixing idea. Getting access to tighten it is the key.

Hello Peter,Peter Balcombe wrote: ↑06 Dec 2021, 22:06 Hi, I suggest that you definitely need some form of wing retainer, rather than rely on tape.
I have fitted Multiplex Unilocs to 1/4 scale models, but have found that they can pop out unintentionally with bigger wingspan models.
I’m not sure how easy it may be to fit given where you seem to be with your build, but I have found that the simple thin aluminium plates shown below seem to work well. They provide enough clamping resistance for normal use, but will pull off in the event of a major force.

These pics are from a 1/3 scale Olympia where the tab was fitted to the wing root rib & access to the fuselage fixing was easy.
I’m currently using a similar arrangement on a 1/3 scale Jaskolka, where a bolting plate has been installed inside the fuselage wing root stub & the clamping bolt will be inserted from underneath.
Another alternative is to have a plate in the wing & the tab protruding from the fuselage, inserting the bolt from under the wing root.

I would wait to try your brakes when they arrive as I am a firm believer that ‘if something can go wrong, then it will happen sometime”
Another possible method is a a strong elastic band or spring going through the fuselage, connecting together hooks on each wing root.
Hope the above helps.
Cliff, I wait for a 1/3 CNC kit of this beauty!Cliff Evans wrote: ↑09 Dec 2021, 08:32 There is a plan for the Cijan Obad Orao at 1/4 scale drawn by Jim Owen in the plans section.
Very good idea! But I would like to keep the hole in the bottom of the wing shroud as small as possible. So maybe glue the captive nut on a bracket under the wing tongue. Wings would be fastened by just turning in the bolt..Or do I miss something?Peter Balcombe wrote: ↑09 Dec 2021, 13:46 If you do use the suggested tongue & clamp wing retention method, you my be interested in the tip Jilles gave me about providing a “washer” which couldn’t be lost in the grass.
Epoxy a captive nut (with spikes removed) to your retention bolt
