Okay, I'm trying to wrap my feeble mind around all the different Aerotech single use 29mm motors. So far, the only 29mm rocket I have is the Hijacker. It's 3" diameter and 45" long. Weighs in at 16oz (according to the manufacturer). The recommended SU motors are F20 and G80. But when I look at the motors available, I find F20W, F23FJ, F25W, F26FJ, F27R, F32T, F42T, F50T, G38FJ, G40W, G77R, G78G, G79W, and G80T. I've tried researching the different motors, but all I can find are small graphs with thrust curves. The graphs show me that some of the motors have high initial thrust and short burn time, or low initial thrust and longer burn time. I get that. But some are so close, they're almost identical. Some of the motors aren't shown in the graphs. They're in the charts, but the charts only show the motors' physical size, total NS, propellant weight, motor weight, and delay times. They don't list maximum thrust, burn time, maximum liftoff weight, etc.
So is the major difference really the propellant type? I read about them in the Aerotech catalog. White Lightning, Black Jack, Redline, etc. Would I be safe in assuming that if the Hijacker will fly fine on a G80T, then it will also fly fine on a G77R or G79W? They all have somewhat similar thrust curves. Or is it mostly trial and error? Is there any more comprehensive information available somewhere for the Aerotech motors?
