Hi Gents,
This week I finally installed the IBU2 Pro I received as a Christmas present into my HL Leo 2 but have run into an issue I can’t resolve. All of the functions and sounds work except for one really important one, FWD/REV. I’m using a FrSky Taranis Tx, which I also fly with, and it drives a servo just fine on Ch2(elev) but for some unknown reason the IBU2’s drive circuit is not responding. I’ve gone through the configuration process as instructed in the manual a few times and even tried it with a different Tx/Rx combo, but always get the same result, no FWD/REV. I’m now thinking the board is defective but would appreciate any ideas or suggestions you guys might have before I begin the process of getting it replaced.
