Flat plate Delta idea
Hey guys,
I've been planning on making a 4mm flat coro delta, same size as a DD but with absoultely no airfoil, just 4mm coro strengthened with carbon fiber rods. I'm going to CA 3/16" carbon fiber rods to the leading edges, and insert a carbon fiber rod in the trailing edge just before the elevons, then a small one across the wing at about the CG. I'm going to give it a wood mount and spine like a PBF, and put an OS46DV-F RE with pipe on it and 9x8 APC prop. I figure the minimal frontal area will let this thing really wind up, but I wonder whether it will hold together above 150mph? I should probably add carbon fiber rods in the elevons too, inside the flutes at the trailing edges there. Whadda ya think? Is this thing going to be stable at speed? -Tom

Combat Deltas fly
I guess the combat deltas flew well enough to make several. I'm going to give it at try. Most of the issues I think are with the flexing of the corex spanwise, but with the CF additions I'm planning it should end up relatively stiff.

fly well, for correx they fly damn well, my second was a bit lighter and can even prop hang, the onsite video doesn't show the successful one. you don't need CF, the second layer underneath and the pipe solve the main flew, the rest doesn't matter.
