Epoxy Wings To Power Skid

Time to epoxy the wings to the power skid.

A confession: Forgot to design the wing length to account for the thicker 1/4" wood power skid. This added a 1/4" to each side, or 1/2" total. There is a gap between the wing halves where they meet in the middle. Ouch!

Quick fix is to print a new middle piece to patch the gap. Will see this in future photos.

Photo 30 shows one last look at fitting of wings to wood. Without the wing skins don't realize the above issue yet. This is the last photo just before the epoxying happens.

Photo 31 shows wings as epoxy is curing, notice item behind pulsejet in the background? White cylinder tube is the inside fuselage support. Gives the fuselage strength and helps keep the round shape. Sorry, about the bright LED light...Only used this photo to show the fuselage support-only photo with it in it.

Photo 32 shows all screws in heat shield to verify it fits with no issues. Wings are solid to the wood frame, only thing left to do is a fiberglass layup to join the spars in the middle. weight with everything on top of scale is at 3lb 3.7 oz.
