Pouring rain here in Central Illinois the past week, so abandoned plans to paint a HPR build and pulled Super Big Bertha from the build inventory. What a great kit. Love the laminated fin design.... just like the Mega Der Red Max. Would be great to see more PSII issues with this construction. Deviations from stock include mini rail buttons, small diameter kevlar harness, nylon chute and baffled coupler. All wood glue except epoxy for motor mount and coupler to airframe.... don't like the "grab" from wood glues. When I go to HPR launches I always bring a couple of Estes E/F fliers to settle my nerves. Nice work Estes..
