Hi Dave

Thanks for accepting me as friend. i live in sutton coldfield so am fairly close i think. i have a quad that i am trying to get going and have fitted an air sensor. It just does not show up on mission planner? the tick boxes are just greyed out? i have a m8 who is checking the unit out, but any suggestions?

Thanks in anticipation

Phil

P.S. its a 700 version not the 500 version i have been seeing probs with on on forums.
