I filled in the holes behind the fins with wood filler. Next, fillets. Again about 5:1 epoxy to milled fiberglass. Masked with tape, pulled with a piece of PVC tubing. I think they came out okay. The rail buttons went in. So did the motor retention hardware. It’s together. I have a good bit of finishing work ahead… although if it’s not fully painted and decorated by June 20, I’ll probably want to fly it anyway.
