Safe, intelligent design, precise manufacture and strict engineering tolerances made Estes rocket engines the standard in the industry. They have been proven consistent and reliable.
Some important features are:
- Lightweight non-metallic casings made from paper and clay materials
- Pre-loaded with propellant - the modeller does not handle any hazardous materials
- Expendable and bio-degradable - use them once and throw them away. Reloading is forbidden.
- Non-toxic propellant - however, ingestion is not recommended!
- 3% of all Estes engines made are static-tested at the factory for reliability and adherence to
performance specifications. If our standards aren’t met, the engines are rejected and don’t make it to market.
The concept of the pre-assembled rocket engine is the foundation of this safe, scientific and
educational activity.
CODING SYSTEMS
Two codes completely describe each Estes rocket engine:
- Colour code: Provides at a glance the specific application of the engine:
Green – Single Stage
Purple – Upper Stage (on Multi-Staged Rockets)
Red – Booster Stage
Black – Plugged for special applications
- Alpha-numeric code: Provides the engine’s performance information.
