I'm considering trying some of the Quest Q-Jet D16s in my Estes Interceptor, instead of converting it to D engines. Can anyone suggest an appropriate delay? I believe the Interceptor uses a C6-5, so I would think that since the Q-Jet will get it 10-15% higher, that a 6-second delay would be okay. Or am I mistaken in thinking this? No Rocksim file is available for the standard Interceptor, so I can't really test it via that method.
