My installation has at least two bugs. One of the models after I take off stops responding to controls and follows a repeated flight path including landing. I have never recorded a single flight. Also one model has the flaps full on loading and they are not controllable despite my using the correct transmitter with the newer dongle. What I need to do is to remove any and all vestiges of Realflight and do a new install. To do that though I need to know where all files are, if there are hidden files, and what needs to be removed from the registry. Hopefully someone has that information. I haven’t had any help or even a response from Horizon regarding the first bug, and I just discovered the second. Thanks for any help, Duncan
