| Engine Blocks For Model Rockets |
Model Rocket Engine Blocks
These model rocket parts are used to prevent the motor from pushing into the airframe. However, they do not prevent the motor from getting pushed out when the ejection charge fires. An engine hook or motor retainer can be used to secure the motor on the aft end. This rocketry part is ideal for minimum diameter rockets, where engine hooks can not be used.
