Stupily large model

Have a look at the wing tube size towards the end of the vid

Ahh Skipo's yuk

I'm not surprised that wing joiner bent, it looks like it is waaaay to small for the size of the wing panels.....

I'm not sure if there aren't two tubes, although still looks like a weak point in the structure

Even if there were two tubes, it is still a horribly inefficient way of designing the spar/joiner structure in something that large. A blade spar (like the ones you see on full size gliders, and that yak of NFJ's, would be a much better solution in terms of weight, strength and durability. I get the impression that that model is just a scaled up version of a smaller model, and no real thought has been given to the magnitude of the loads being applied to the airframe....

Still, the colour scheme was nice....

Andy

but but but the LMA said it was ok

enough said I think, it's also a bit strange how he lost both ailerons as well

I dunno, maybe it was considered a suitable design for flying right hand circuits. It seems like a bit of a loop was too much for it though

The ailerons could have been lost if the wiring, or plugs/sockets type connections to the wings were lost as a result of the joiner bending....
