"Estes Honest John (Scale) Great Scale Model Rocket, but could use a few improvements"
champfluff
Estes BT-60 based scale Honest John model rocket is the 5th release of this specific rocket and despite the scale, it still seems to be quite the popular model. First, the plastic parachute should be upgraded to a nylon parachute same size, just cut a small spill hole for a quicker descent. Second, install an ejection baffle to prolong chute life. Third, upgrade rubber shock cord to Estes Pro II elastic shock cord and mount to ejection baffle. Fourth, when it comes to up powering, a) either leave out the engine block for longer 24mm, 3 and 6 grain composite motors, or b) up power to 29mm motors, upgrading the centering rings to plywood. Fifth, laminate the balsa fins with Cy/A adhesive and printer paper, allowing Cy/A to wick through the paper, for lightweight strength and near zero fin flutter. Sixth, if up powering, add additional nose weight to rebalance for new C/G and C/P. Seventh, upgrade launch lug and spacer to 2 rail guilds and spacers. Oh and I know that a 38mm motor will fit in a BT-60, but glassing the tube and a fiber glass baffle might be a little outside of my comfort zone at this time. With an Estes 29mm E16-8, or F15-8 and apogee at over 2,000 ft. the launch and recovery will be impressive and if that's not enough use composite 29mm motors. Best wishes on these improvements and anything higher power, I'd use a GPS tracker.

I purchased 2 Honest John's at such a great buy... one to collect and one to build. They both arrived in great condition for collectors like me with OCD
