The recievers you get no will come minus the crystal unless it is in the package. If they ask you what channel your transmitter is on then it comes with the crystal, If they dont you'll need to get the crystal. I have the same Plane and engine but I fly JR662. The next Plane I build will either have JR flightpac or Hitech. FYI the Hitech has the battery included but the JR doesn't, neither has th crystal included..

Just my .02
