Hey Matt,
That sounds like an interesting variation on the Kaos! A twin 40 cc with plug-in wings - nice. Are you planning on keeping the 300% thick foils...
I went down to 14% from the originals something which lends itself well to a plug-in approach as it leaves some fuselage below the wing on which the panel can make contact.
Where do you plan to put the pipes? Slung right underneath the fuse? If so, then plug-in panels sound like a must. Removing one pipe each time the wing is bolted on or removed is chore enough. Having to do two pipes...
BTW, which pipes work well on that engine? I am thinking of that very engine for another 2m build. Not sure if I can get the pipes into the design though.
