A mini-engine powered square "tube-fin" sport rocket, built primarily by my 9 year old daughter, and painted by Dad according to her specifications.
First rocket of the day picked and prepped by my daughter out of "her" fleet. Nice boost, quick and straight. Good chute at apogee, recovered on the field with no damage. I am usually unimpressed with this rocket just because it flies low and slow, but I have to admit it matches up with the A10 motor pretty well and is a reliable performer.
