Default Servo Question

This is either really easy to answer or I have something messed up. Setting up my Arrow, The servo for throttle pushrod moves in the wrong direction. I need it to spin opposite of what it does now. I am guessing it is in the radio's manual but not sure.

To be specific, with the radio set to full throttle, the servo arm needs to spin counterclockwise to push the rod and close throttle, it doesn't. It wants to spin clockwise, which won't work.

Most modern transmitters have a servo reverse function for each channel.

If you have a computer radio servo reversing is in the programing
if you dont have a computer radio there is a reversing switch somewhere on the outside, actually there will be 4 small switches I believe throttle is channel 3

It is a JR 6 channel Computer Radio. I found it in the manual this morning. I was working on the plane last night and the throttle hookup was the last thing I was going to do for the night. When I saw that it wasn't spinning right I just cut the lights and went up to the house. I didn't think to grab the manual before I left. After reading above, I looked in the manual online this morning and found it plain as day. Even a Chapter heading for reversing a servo.

Thanks.

I just thought the owner's manual was something you kept in the glove box

I propped up a short leg on a coffee table with mine
You may need to reverse other servos before you are done to get all of your control surfaces moving in the right direction.

Missleman is absolutely correct. You need to check , recheck , and check again the directions of your control surfaces from behind the aircraft on the ground before and after you start the motor. Ailerons, left stick, left aileron should go up. Right stick, right aileron should go up. Pull back on the left stick, elevator should move up, push it forward, elevator should go down. On the left stick, left and right should give you left and right rudder, accordingly. Once you check it a few times, you will get used to doing it. I do before every takeoff. If you have a computer radio, it can save your butt and your plane if you somehow happen to get the wrong model turned on on the radio. Good luck!

And when you get all done and are satisfied that all is correct..........take it to the field and have someone there recheck EVERYTHING.

No worries, my instructor will be doing a full inspection prior to it ever leaving the ground. Also, a long time pilot at the field has one. He'll give it a check as well. Trust me, I have zero interest in rushing this. My wife would never let me live it down if I crashed this thing trying to fly it on my own to soon.
