Lots of different thoughts and opinions out there, but after having my GP Reactor for 2 years/120+ flights now, and reading lots here and more so on FG, general consensus seems to be a good rx (I use a single Futaba 6014), either a single or dual battery setup, and a good bat share type of switch. I would recommend a Wolverine switch, 2 1800 LiFe packs, and a RCEXL ignition kill/BEC setup. I'm using that BEC now, eliminating the ignition battery and switch, and like it very well.

Servos run the gamut in quality, price and performance, but a good digital MG servo, such as Hitec 7985's or Savox 1258's on the ailerons and elevator, and a little stronger servo, like a Hitec 7955 or Savox 1256 on the rudder.
