I’m building a scratch dual deploy 4” G10 3FNC rocket, and was planning on
using 54mm motors. If I used a 75mm MM then I could launch my first L motor up
at XPRS in September (and 54mm’s with an adapter). I will be doing slots
through the airframe with reinforced filets inside and out and I already have
1/8” G10. Most kits online look like they use 1/8” G10 for 54mm kits, and 3/16”
G10 for 75mm/98mm kits.
Am I asking for trouble if I use 1/8” G10 fins with a 75mm motor like a
Ceseroni L800 or Aerotech L850W? In ROCSIM both look like rocket would be
above 1100 ft/sec for about 2.5 seconds ? Or should I just stick with the 54mm??
Any input would be appreciated!!
Thanks,
John
