MK elevaltor crank on a G-trick. Isn't really nessessary.
I've been flying one for 3 years... it's precise.. but not anywhere near Hydeout/Alliance even Focus precise! See it for what it is, a damned nice Sunday pattern/3dish .90 model.
I use a 4/40 Y rod supported inside and a decent 7kg/fast Futaba servo. The fact thyat the Stab and/or wing are non ajustable will cause you far greater heart ache than an unnoticable differential on the elevator halfs!
