B4-4 Model Rocket Motors – Six Pack

B4-4 model rocket motors offer moderate thrust with a longer delay, making them suitable for slightly heavier rockets and improved altitude control. These model rocket motors provide a balanced flight profile with a smooth boost phase followed by a timed delay that allows the rocket to reach peak altitude before deploying the recovery system.

This six-pack of rocket engines UK customers trust is ideal for schools, clubs and hobby rocketeers progressing beyond beginner motors. B4-4 engines are commonly recommended for mid-size rocket kits and educational projects where consistent performance and reliable recovery are required.
