jtatarin,

If you are refering to my post, note I said pull on the SURFACES, as in controll surfaces, ailerons, rudder and most important, the elevator.
Do this to ensure that the ca hinges havnt cracked and broken each time you fly.
If there is any failure, its not likely all will break at once, so, if you discover a broken one, dont fly till its repaired.

As far as servos, you can remove the linkage from each servo and move the controll rods or cables back and forth by hand.
There should be very little if any resistance.
If you find it difficult to move, you need to figure out whats causing it to bind and correct the problem.
If the servos are binding, youll usually hear them "hunting center" when you release the sticks.

Im not familiar with the radio you mentioned.
