OS 1.60? So you are getting the 27% Extra? I thought you were talking about the .40 size blue & yellow one. I just sold my 27% and it is a good plane as well. My avitar picture is my Extra in flight. My only complaint is the landing gear. They aren't in a scale location so they look wrong and I just don't think the forward mounted, swept back gear work all that well. They are also a little springy for my liking. Gear aside, it flys great though.

The 1.60 will definitely fly it well but you may consider going gas. You can get some low cost 50cc, high performance gassers now such as the Turnigy 50cc HP from Hobby City and they run very well. You'll get to use much less expensive fuel and have no slime to clean off the plane at the end of the day. The only down side to them is that they will weigh a little more than the glow 2-stroke once you factor in the ignition box, ignition battery, etc.
