The apogee motors for OSCAR-10,and OSCAR-13 were solid propellant 400 Newton trust motors donated to AMSAT-DL by the Messerschmitt Aerospace Company in Germany.
Only Phase 3A had a solid fuel motor. AO-10 and AO-13 had liquid fuel bi-propellent motors the same as AO-40. No matter how well designed they are, they still have the potential to blow up the entire launch stack if something goes wrong. Since Dick Daniels is no longer with us, the knowledge has been lost and we will not be launching any more of these in the future.
