Smo0: The manual recommends re-binding after any changes in installation. So, you may wish to do that. Also, the TX antenna can be turned from the horizontal to the vertical (it is on hinges) to accomodate the polarity of the transmitted signal to the receiver better. I suggest you rebind and then when flying, point the antenna skywards (rotate it to point up so that whey you are holding the TX naturally, the antenna looks like the diagram below).

Also, please describe what happened to make you believe you lost communications with the receiver. That will help us try to figure out what happened.

CGr.

PS: Hey Allan.. how goes it? Dick.
