Mid-power rocket on launch pad on frozen lake

This is a highly modified Estes Great Goblin mid-power rocket. The design rationale was to make a rocket that I could fly from the club’s main field – a gravel river bar. This required reversing the fins so the rocket will land on the aft end of its body tube, or along one edge of a fin. The balsa fins are reinforced with printer paper glued with epoxy to both sides, and then a wrap of medical acetate tape laminated to the trailing edges. The strakes are for fun. Inside, I added an Aerotech baffle system to protect the parachute.

It flew flawlessly in March of 2025 from Lake Louise. An Aerotech F26-6J took it to about 1100 feet.
