What is/was the biggest professionally manufactured, commonly retailed BP engine? I actually flew an FSI Mach One Dart, which used the F-100 booster motor (with fins glued to the casing as per the directions), I forget the upper stage motor. I don't know if it went supersonic, but it was a very calm day and it was climbing very fast when I lost it - I found the rocket with it's 6 foot streamer 2 days later on the way to work, about 2 miles away. Never found the F-100 casing with fins.. I hear tell Centuri had some F's at one time. Is that it for BP or were there bigger ones? Neutrodyne
