The CL-8020-14 motors fit the Inductrix FPV+, and they seem to produce slightly more thrust, but there are two issues:
1. Diameter of this motor is a fraction of a mm larger than the stock motors. Installation may require some heat and/or patience.
2. Plug polarity on the FPV+ FC is reversed. You need to swap CW and CCW motors and run them in reverse, or switch the pins in each plug.
So.. its possible to run the CL-8020-14 in the Inductrix FPV Plus, but not 100% plug&play..
