- After having had the opportunity to see a few FSI motors being used at a
- recent DARS launch, my recommendation is that launch weight is irrelevent.
- The odds are the motor will CATO and destroy the rocket on the pad, anyway :-)
- (or :-( ).
-
- When I was flying in my previous life as a rocketeer (a couple of decades ago)
- FSI motors were very highly sought after and seemed more reliable than even
- small Estes motors. The choices for 'E' and 'F' motors was between Centuri
- 'MiniMax' and FSI. The people flying in Fort Worth, Texas, at the time all
- seemed to prefer FSI. That no longer seems to be the case. Has something
- happended that FSI motors are much less reliable than years gone by?
- Am I wrong about that? Since FSI motors are relatively big and use black powder
- fuel do they suffer from the same temp cycling problems as Estes D motors?
-
- I also haven't seen a motor certification list in AmSpam, recently. Are FSI
- motors NAR certified? Are they contest certified?
