Great all around motor
By c_f_bender September 19, 2014
One of my favorite single use motors. Good visual flame, and not so much punch that the rocket is gone too fast to enjoy it. Also, a good long 2+ second burn time. Perfect motor for 1-2 lb rockets.

Manufacturer Comments
  • ATTENTION: the sale of G motors to persons under 18 years of age is prohibited by federal law.
  • Product is flammable. Keep out of reach of children.
  • Masking tape is required for rockets with a motor mount that does not have a motor hook or motor block or has a motor block deeper than the motor length.
  • Each Aerotech Composite Rocket Motor is stamped with a code which gives important information about the motor's performance. The letter indicates the total impulse (in Newton-seconds) produced by the motor.
  • Store in a dry place where the temperature will remain between 45 degrees (F) and 100 degrees (F).
  • Use Aerotech composite model rocket motors only in model rockets designed and built for them.
  • See safety code procedures within instructions.
