RE: Revolver or Pulse for 2nd plane
I say go for the Pulse. while I haven't flown the new Revolver .60 yet, I am very familiar with the Revolver .46. The Revolver is an outstanding flying airplane but it can be very fast and very maneuverable. It doesn't slow down as easily as other planes either making landings a little more tricky.
I'd save the Revolver for after you've mastered the 4-Star and/or Pulse. You'll appreciate more then and have more fun with it.
