I know this is an endless subject, but I must tell you how disappointed I was when I tried Multiplex EasyStar.I attached some pictures of my plane.It looks good, but flying caracteristics are weak.
My plane is stock:Permax 400/6v motor with 12,5 x 11 cm propeller.
The stock version is useless for UAV and FPV.Main reason is the motor, but I also think the plane may be the culprit.Gliders may fly longer, but they go with the wind.
My Multiplex EasyStar with landing gear:
There is a reason for EasyStar lack of landing gear.The reason is its poor controling behaviour(small control surfaces and big wings)
