Have not flown the Eaglet, but it is the same system
as on the Javelin. Control is about the same except
you don't need to use as much rudder (pedal) since
the spoileron creates drag on the down wing that pretty
much counteracts the adverse yaw from the lift differential.I understand the Eaglet was rather touchy to fly.
The only one I laid my hands on seemed rather flexible
in the tail feathers.jbd
