RE: transission to 2.4 Ghz

You can switch receivers back and forth between planes if you want. The only potential problems I know of are that as you pull the servo and power connectors on and off they get looser and looser. There's also the possibility of reversing something like ailerons. I've done both things mentioned but luckily caught the flubs before flying in pre flight check. To me it's worth it to have one receiver with its own battery for each plane and never mess with it once it's installed.
