I'm currently building a Mercury Engineering Hijacker. I was originally going to build it with a 2x24mm cluster motor mount, but decided to leave the single 29mm instead. But I'm confused about which Aerotech single use F motors I can use. The kit calls for either an F20-4 or F45-5. I can't find an F45-5 motor anywhere. But there are a lot of other F motors listed, like F23, F25, F26, F50, etc. Which motors would give me slow liftoffs? For leap off the pad liftoffs, I figured I'd use a G80. Any and all suggestions and/or opinions are welcome.
