Don't worry, the pushrods are hooked up already. Fold down the aileron and you should see a pushrod with an L bend right against the drag spar. You will have to cut a little bit of the top skin to get the pushrods to hook up to the control horns. Also hook up the servos and center them before putting the control horns on the ailerons.
The cut on the top skin on mine was not just a simple narrow cut but had to be widened a little bit since the pushrod ends were not a simple L Bend but kind of a box L bend.
I just finished mine but have not been able to fly it due to been sick all week!
