I was trying to install a Lemon Plus 7 channel receiver, an earlier version to current one. In one manual, it says the receiver can be mounted with the switches right side up and upside down. In an other manual, it says only right side up. I mounted one upside down and everything works propertly except when I switch to stability mode, the ailerons want to flip the plane upside down. if I turn the plane over, the ailerons woke fine. When I removed the receiver from it's mounting location and turned it right side up, all worked fine. Has anyone been able to get the receiver to work upside down?
