Mate you will love 2.4. I keep forgetting to put my key in the frequency board[:@][:@] bad habbit , and no areial to pull up. Just watch if fly with 2.4 then pick up a radio running 36meg. I did this once, forgot to pull the aerial out, you know how that ended !!!!!!!!! No once you have fitted a couple planes with the remote receivers ( no more aerials hanging out of the plane) you will never go back. Make sure you put the antena's at a 90 degree to each other (thats what spectrum say to do ). If you dont you won't get the range on the RX to TX. Don't forget to re bind after you finished the install before flying, it sets the fail safe properly. ........ cheers mate
