Put some pictures up below of my aileron mod to my easy star. I put carbon fiber rods in the foam to help give it more stiffness. Also, just used simple packing tape for the hinges after cutting 45-degree slices out of the bottom of each mating surface. Then, used Hitec HS-55 micro servos in the wing. Had to use some extensions for the cords (should have probably put it in closer and might have been able to avoid having to use extensions). I only had 24" ones right now, but I think 6" ones would be just fine. I'll swap them out when I get the chance.

Dual/Triple Rates and Expo
There is a pretty good web page that describes how exponential rates work (the negative vs. positive expo on JR vs. Futaba sort of messes me up too). I also put together a quick Control Rates XLS spread sheet to graphically demonstrate how the control surface should move with various rates and expo settings for a given stick movement and to help myself visualize how the response works for setting targets on my Futaba 7CAP. I am thinking about trying to even do a 3D plot to incorporate subtle p-mixing, but that is probably overkill. For now, this allows me to visualize what I want to do to moderate response around center, but still get full range response for 3D flight. The file currently has a setting for user settings, demonstrating how to limit the beginner's tendancy to "over control", but still deliver the same initial sensitivity/response with 65% rates and 70% positive expo.

Easy Star
I just built my Easy Star kit and got it all setup. Here are some pics with the HXT 2835 2700kV brushless motor installed, and a Turnigy Sentry 25A BESC with a Zippy 2200mAh 3S1P LiPo. I put the BESC on the outside to try to help keep the heat down. The HXT motor sure seems to run hot (hope it isn't a dud). I still have to pop the Hitec Neutron 6S Rx with HS81 servos in and get the push rod throws adjusted as well as make a final CG measurement. Hopefully I can maiden her tomorrow. Found a good EZ* Fan Site page too.

Cheaper...Wild Hawk
Of course, once Harbor Freight starts carrying these, you can begin considering them "disposable". The Wild Hawk is a knock off clone cheap version of the EPP foam Easy Star. Super forgiving, very cheap, and easy to fly...got to see if our local Harbor Freight has one.
Check out the Wild Hawk.
