Expo what is expo?!?! No just kidding.. Personally I dont like a whole lot of expo when i fly my planes. I like to "feel" what the plane is doing. Granted on some extreme rates it does make it kinda twichy so I do add a little but not much.

BShin: I really like the way you have done the rear of the plane. I was thinking of building it up for some extra support and strength but, didn't want to overload myself with building. I just did the standard route and used contact cement and glued it into place. And with some of the extra covering material i hid all the lines. Looks pretty good, and it quite sturdy also. We'll see..
With the metal gromets yes you put them on the top side of the servo. Yes it adds a little bit more protection also it adds something sturdy so under operation the screw has something to but up against instead of the rubber. If you know what im talking about... hehhe.. Sometimes i just wonder myself. hmmmmm...
