BI Think of this: physically, my cub's wings are subject to no greater force than any other wing (and probably less than aerobatic planes, as this is a scale flyer). So, from a physics standpoint, is the cub's wing any more likely to fold than say a wing of similar dihedral, length, etc? The answer must be no.
So it goes back to the strenght of the spar, the quality of the kit, and the fastidiousness of the builder. [/B]
Paul nothing could be further from the truth as that statement. To suggest that two different model designs should be of similar strength because they are of similar span, Dihedral and Shape is patently ridiculous and For the reasons I outlined above.
Your second post identifing the type Cub was not up when I posted. I have no familiarity with that ship and indeed I suggest you check before flying without struts. The fact remains there indeed are some model Cub designs that can be flown without the struts and there most certainly are some that cannot, You asked the question why in your first post and I did my best to explain. If you care not to accept that then thats fine
but I will not belabor the point any further.
