Was very disappointed by this nugget http://diydrones.com/forum/topic/show?id=705844%3ATopic%3A25130
which killed our hopes for EasyStar ecstacy. So many junk parts are emerging from Vicacopter that a throwaway UAV based on the EasyStar & GPS was a goal. We now have 2 IDG300 gyros, 1 PG-03 gyro, & 2 GPS modules.

There is an anecdote here http://www.rcgroups.com/forums/showthread.php?t=663091
which describes stabilizing the EasyStar with a yaw gyro. The yaw gyro stabilizes roll by correlating roll & turn rate. Release rudder input and the gyro defeats the turn by centering the roll.

Not sure if anything can be done for pitch stabilization.

That was a lot of very smart and interesting speculation. But I think there's only one way to find out: somebody freakin' fly one!

I'm not going to do the GPS-only test because I can't fit my Basic Stamp board in an EasyStar (I also think it won't work). But the rate gyro test is pretty easy to do. Maybe this weekend--I've got a heading hold gyro that I think I can switch into rate gyro mode. I still don't know how to combine that with an autopilot, but it might have some application for an plane with ailerons, like the EasyGlider.
I am going to try GPS-only flight with an Easy Star, I think (with manual pilot that will, hopefully, be able to prevent any accidents). Is space really that big of a concern? I haven't bought an airframe yet but I am concerned about the complexities of coding aileron flight with an Easy Glider.
If you're using your BOE board, it won't fit. But if you use a Stamp on its own,with a custom PCB for the other necessary electronics, I think you probably can do it with the EasyStar.

Suspect the EasyGlider is meant to replace the EasyStar. The glider probably flies like an EasyStar if the aelerons are fixed, the rudder is extended, and it has a yaw gyro.
Does anyone have some insight as to whether the Easy Glider will fly essentially like a rudder/elevator only model if the ailerons aren't touched during autopilot mode?
My guess is that eaystar can handle flying with rudder only due to the winglets. If you manage to create some sort of similar winglets on the easyglider you should be able to fly it with just the rudder and elevator.

Hope it helps.
The Easyglider has quite small elevator and especially rudder control surfaces. They are proportional to the presence of ailerons and to the longer wingspan. Essentially, Easyglider is a glider with a surprisingly good thermal capacity. It will eventually be steerable to a certain extent without ailerons, but it won't come out of a highly banked or reversed attitude without ailerons as fast as the Easystar. It's turning radius without ailerons will also be quite larger than ES due to the smaller control surfaces and bigger span. So reactivity will be limited. Another factor is that the Easyglider is not as autostabilizing as the ES, the latter being almost like a high wing trainer with more dihedral (larger and higher winglets in proportion to wingspan).
