Sounds like its a binding issue, try to push the wires in individually, if they feel tight this way, you will need to either, get pushrods with a smaller diameter, very hard to find i guess, or change the pushwires tubes (PITA), what i would do is use some sandpaper on the pushwires, takes long to achieve results but its just my two cents, and if i am mistaken, let me know.
don't let this issue affect you, once you get airborne you will love this planes, i run with a 91. and a 15x8 blade with 5% nitro and 18% synthetic and 2% castor. balanced on the recommended c.g, Floats, floats, floats.
check my gallery to see mine.

Has anyone had issues with the elevator pushrods on this plane. Mine are so tight fitting in the tubes that the servo buzzes and the whole server trays twists as the arm is moved. [:@] I thought about getting smaller pushrods that would slide through easier, but the the supplied rods are 1.8 mm and the only thing less is 1/16!QUOT!. Cannot find anything carbon or strong enough below 1.8 mm in diameter. Thank for any help...
