Hey all, i am in the process of building my second Ziroli Panther and i wanted to use the wing plug ins that are available on most yellow kits. The narrow aluminum spar, and spar retainer. Where can i get these, and also, do you think it would be structurally strong enough. Ziroli calls for aluminum wing tubes, on the plans. I used them last time, but did not generally like the retention design he has on the plans. Thanks in advance, Nick

Oh one more thing, can i get the spars in a longer length as my wings are bigger than yellows.

Nevermind, i just found them and they make them in 10 inch lengths it looks like.

Hey Shaun, (YELLOWAIRCRAFT), how much do the sets of the plug ins cost (A2002). Thanks, nick

check out sig manufacturing they sell them also......
