So Long PRO - Estes

This two-stage rocket model for 29 mm motors was created for extreme altitudes.

The structure is very simple and construction is not complex. However, it does require some manual dexterity and modeling skills in preparing, sanding, gluing, and assembling the parts.

Designed for traditional 29 mm motors, this two-stage rocket model is suitable for TSP F35 motors. It can also be launched as a single stage, using only the upper stage and not the booster. In this case, 24 mm motors such as the TSP E12 and E20, or various Aerotech E and F motors, can also be mounted using an adapter (not included). Of course, it's possible to fly the single-stage version with a TSP F35 or even Aerotech 29mm disposables.

Composite motors like Aerotech or CTI cannot be used in the two-stage version because the upper stage ignition must be activated by the booster stage motor.

The So Long includes a large payload section for launching your experiments at high altitude, and is recovered via a streamer to prevent it from being blown away by the wind given the high altitudes it can reach.

Decals are included in the kit for an attractive aesthetic and to improve visibility.
