| Meat tray foam wings about to be bagged. Epoxy squeegeed off of tissue on clear carrier film, then laid over foam. For this wing, black tissue on bottom, red on top. | Layup inserted into ZipLoc bag. 8 x 10 sheetof glass used to assure the wing cures flat and warp-free (the foam is sanded like balsa, no hot-wire or wing beds). Whole piece of red felt used for breather under the glass. | Finished glider, 2nd place in 1/2A B/G Team Div. at NARAM-43. Note the very smooth finish. | Alex Seltsikas photo of Cuda wing being bagged. Note EZ-vac pump at lower left. | Summer/Fall of 1980. Used VERY long big pods to boost as straight as possible on 1 and 2-stage D12's, due to lack of skill to do a hot or long-burn boost. As skills improvd, pod size was reduced. |

Sky Dart 2X R/C model,
launching off of a C-rail | Wing from 1/2" blue foam | Click here for more SKYDART info | Both this and the Zagi use outrigger poles to hold the wings level till ignition | SkyDart with decals and a fitting background. |
| Zagi flying wing conversion project, begun by Kevin McKiou & completed by George Flies on G12 reloads, 48" span, about 28 oz liftoff. Model required a lot of noseweight, and is a heavier model of the Zagi kit variants. Boosts nicely (though not high for a G12) and is fun to do aerobatics with. |
