C11-3 Engine Bulk Pack


In the C-class there are no engines more powerful than the C11-3. Use the Estes C11 engines for heavier rockets, like those with a PocketLab payload, or for larger drag profiles. The 3 second delay makes it optimal for rockets that will not have a long coast phase. For lighter rockets, or those with an aggressive aerodynamic profile, consider the C6-5 for the longer delay.
