Here's the 24mm version of the Orion. The changes include a 4" length of ST-9 and a shifting of the first centering ring 1" forward. A longer engine hook and thrust ring round out the mods.

Length: 22.65"
Diameter: 2.04" (ST-20)
Fin Span: 7.34"
Weight: 3.68 oz

D12-5........997'......Dv 32 FPS......36" x 3/16" rod
E9-6........1622'......Dv 26 FPS......48" x 3/16" rod
E15-7.......2305'......Dv 16 FPS......36" x 3/16" rod
F21W-8......2855'......Dv 7 FPS.......36" x 3/16" rod

As you can see, the larger motors are much better suited for this model.

Enjoy!
