FSI could offer "split" motor adapters (like Estes' plastic ones) that could be screen-printed to look like the old FSI 21 mm and 27 mm motors. These adapters could accept 18 mm Estes and Quest motors and/or Estes 13 mm motors (two different sets of 21 mm and 27 mm adapters, with differing internal "rib" heights [and different printed material on their outside surfaces], could cater to this). The 13 mm motor size 21 mm and 27 mm adapters could be printed to look like lower-impulse FSI 21 mm and 27 mm motors than the 21 mm and 27 mm adapters that are made to house 18 mm motors.

Or I could do an old stand-by and just use a buttload of masking tape to fit an 18 or 24 mm motors in them...... |

We are going to adjust all of them to take either the 18mm or the 24mm motor mounts. At the time of FSI the standards were not set, but as they are now, we'll adjust to match. BTW the FlightFoam nosecones are awesome. They can be sanded, primed, and painted, and hold 10xs the detail from a standard vacuformed nosecone.

One hard decision that might have to be made:
Whether to make the larger "classic" FSI tube -- the one used as a BT for the OSO and Viking IV and the lower tube of the Nova and Orbit and such -- a bit larger. They were sized for the 27mm E and F motors, but could barely fit an Aerotech motor. Making the tube a tiny bit larger would mean the kits could fly with (say) Estes BP E and F motors. Or, keep the size as it is and supply a 24mm mount. There's a nice variety of 24mm motors and even the "large" models like the OSO and Voyager will fly really high on them.

Make them capable of taking a 29mm with a sleeve to stick in for a 24mm motor.......

I like Joe's idea.
The fairly new Estes 29mm engines closely approximate the old FSI F7 and are more reliable. Now if they would just make a core/port-burning version of the F15 as a "F70" to approximate the old F100 in a reliable format.

Especially a booster version. I used to wow the scouts in our old troop back in Texas by launching a two stage with a F100 to a F7. Never had a CATO with that combo. However I did have a double CATO with an E60/E60 combo. First stage lit, went about 10 ft, CATO, that lit the sustainer and it went about 10 ft and another CATO. Maybe also make a core burner version of the E16....... |

The old FSI E60 was the biggest POS rocket motor ever made.
I had a well over 50% cato rate with those turds. Might still have a few of them...would have to chek my OOP motor stash. I figured they were quarter-stick firecrackers that sometimes acted like rocket motors.
