Overview

The F15-8 engine offers a robust thrust profile, enabling your rocket to achieve significant heights with a smooth and steady ascent. The 8-second delay before ejection is optimal for rockets that benefit from an extended coasting period, ensuring peak altitude is reached before deploying the recovery system.

These engines are compatible with model rockets designed for 29 mm diameter engines and capable of handling F-class impulse. Always refer to your rocket's specifications to ensure suitability and safe operation.

Each package includes 2 engines, 2 starters and 4 starter plugs.

Endochronic Spec Issue

The web page gives a thrust duration of 3.45 seconds.

The thrust curve graph calls it ~3.0 seconds.

Look closely at the graph - count the time axis increment marks. Something is wrong between 2 seconds and 3 seconds, time gets compressed?

Please publish corrected graph, and get the longer delay ones back in stock. Kindly give this motor the thrust curve graph it deserves. PS, Isaac Asimov is smiling.

Great Rocket Engines for custom TVC mounts and rockets!

Great Rocket Engines for custom TVC mounts and rockets! The high burn time makes them powerful enough to lift any avionics stack that I have( I fly avionics with exclusively black powder), and the extended burn time allows the TVC mount to hold a stable orientation for a while!
