KnB 7.5 FI RE/prop choices????
I have a K&B RI RE motor that I used to run an APC 9x7 on. Spun way up (20,000rpm). Depending on the pipe length, prop and rpm will vary. Because it was basically a modified F1 motor with a DF pipe, this motor had no throttle. I used an in flight mixture to start it rich and then leaned it to run. It was a pressurized system and it was possible to kill the motor by going really rich.
