"Great rocket, but..."
tank1984714
The contents of this kit seem to be a little lacking compared to the other Aerotech kits. The fins will need quite a bit of cosmetic work around the base. The flashing left over from the mold was pretty sloppy. Be warned that if you plan to clear coat this rocket after painting, the decals do not accept the clear coat at all. The clear will just pool on top of them giving you a rippled water look. Also the piston seemed to be way too tight and needed quite a bit of work to get a better free flowing fit. Overall I would still say this is going to be a very fun rocket and seems durable enough to last for many flights.

"Liftoff weight"
01rocket (01rocket@gte.net)
This rocket is among the heaviest 4 inch rockets of its type. That makes it easier to fly in a small field and it certainly is very easy to build. However it also means you need more motor (cost) to fly it. LOC Precision kits with wood fins are lighter and U.S. Rockets kits are lighter still while being strong too. More motor mount diversity too. The Sumo is a good kit.

Comments

  • Only use AeroTech Composite Model Rocket Motors in this High Power rocket.
  • Do not modify the design of the rocket!
  • Read and follow the Model Rocket Safety Code of the National Association of Rocketry (NAR) and comply with all federal, state,
  • and local laws in all activities with model rockets.
