Derek, after seeing this video... The prior owner installed the Ikon with the USB port to the rear. It is going to be near impossible to get this plugged into it in that orientation with that small gap to the motor can. If you intend to use the cable to plug into it while that Ikon is on there you will run into a problem. IF you only intend to to use it on this mystery project you're talking about, then you should be fine.
Also, I see that the Ikon is setup with an external gov sensor. You will not be able to use this with the 7200BX, so you'll have to setup the ESC's governor.
