This past Saturday we flew our 4.9x upscale of the Binder Design Dragonfly. This rocket was built as an after-school project with five sixth grade girls and myself. It flew at NXRS near Brothers, Oregon on a 98mm K3800 built for us by Mike Fisher of Binder Design/Fisher Research. It reached an altitude of 800' and everything worked as planned. We were very happy with our shakedown flight, next flight will be probably be on a commercial K or L, hopefully with an EX M in its future as well.
I will be doing a detailed build thread when I get time, but here are the basics (dimensions are approximations).

27"x11"x5/8" Elliptical Fins - .06" CF Plate laminated to 1/2" End-Grain Balsa Sheet
1/8" CF Plate CRs and Thrust Plate
Internal Fin Can Structure made from 1/2" End-Grain Balsa laminated with CF cloth
16' Rocketman Parachute with 55' Harness made by OneBadHawk
5:1 Ogive - 12.75"x63.75" built by Python Rocketry
