"Great all around motor"
c_f_bender
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.

"Great motor nice slow burn!!"
rbeard2 (Dayton, OH)
Another cool engine from Aerotech. The G40 burns for about 2.5 seconds and is a great choice for rockets that have been upgraded from 24mm motors to 29mm motors. This is because with the higher initial impulse motors (like the G80) the thrust spike may be too much for the structure of the upgraded rocket. This G40 combined with a First Fire Jr. ignitor is THE hot combo for upgraded mid-power rockets!

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.
