you have the idea on the controls, nuetral sticks, nuetral trim, servo arms at 0 or 90 depending. hook up the conrol surfaces with them at nuetral as well..adjust the pushrods to get the length correct....
Throttle...throttle closed...throttle trim 3 clicks up from the bottom...the servo arm not at 0 or 90 but something toward closed....hook up the pushrod with the carb closed...advance trim so you have about a 1/16th to 1/8 opening..now move the throttle to open and see if you have the carb wide open...if not adjust back and forth between closed and open until with throttle closed and trim down there is no opening and with trim up till 1/8 or 1/16th open then move the throttle wide open you have a wide open hole in the carb
