This has to be one of my new favorite motors for my smaller high altitude scratch builts. In a 29mm (strong) body tube rocket with a 24mm motor mount, this motor really hauls. The 8 second delay is generous to allow for a nice long coast to use up energy. I recommend that you paint your rocket a color that is easy to track as this motor is designed to send them high. The Blue Thunder propellant can be a little hard to track until the actual tracking smoke kicks in about a second or so after burnout but luckily it is continuous after that right up to ejection.

This motor is kick butt from start to finish so I do not recommend this for rockets that use the standard Estes type thin wall body tubes and motor mounts. Build stronger and you will not be dissapointed as the energy to weight ratio for this motor is the highest in the industry according to Aerotech.
