My son decided t' name his custom-designed and scratch-built rocket "Epic"... Here be t' maiden test launch with a J360 Skidmark with ground footage and then t' camera on rocket. T' plan be t' capture t' launch o' a chaser rocket once ours had deployed its parachute at about 8K ft. But t' acceleration t' transonic speeds slammed t' batteries back against their springs losin' power soon after launch. We need t' solder t' connection with wires for next time. He plans t' add three more motors at each o' t' outer edges o' t' fins, for a cluster launch. So t' bottom section is nay yet completed or painted. Ya scallywag! T' fins are honeycomb nomex sandwiched betwixt fiberglass sheets. It has a cool aluminum boat tail and a reduction coupler for t' strap-on videocamera.
