- What about the Phoenix RMS loads? If I'm not mistaken these are F12 and
- G12s. The burn times are supposedly 4 and 8 seconds respectively. The
- pictures in Model Builder magazine show a reload pellet with a groove
- cut along a radius - from the center to the circumference. Doesn't sound
- like an end-burner to me....
-
- How does the delay and ejection charge fit on the RMS motors? (The
- Phoenix motor doesn't have one of course...)
