Default Servo Mounting

The first thing I do is mount the servos in the fuse where they are supposed to go, then I hook them to the battery and reciever, next I turn the transmitter on and let the servo wheels go to there neutral position, then I turn the radio off and mount the plastic star shaped things with the wholes in them? them I hook the control rods to them. I am just wondering if I am doing this in the right way. I have an Avistar.

Thant's exactly how I do it. Just make sure you get the mechanical adjustments as close to neutral as you can. If you do this, you will not have as much adjustment to do via the radio.

Exactly, good thinking!
By feeding some electricity to the servos the servo motor will center and when you then hook up the control linkage with the control surfaces lined up, everything will be centered and later you can adjust the control throws and trim via the radio.

What do you mean by mechanical adjustments, or adjustments to what?
How do I connect the control services(stars) to the Wheel? with that screw in the center that holds the wheel on?

Also, anybody with an avistar can tell me the best way to connect the Hinges wings?

I'd make one correction. Always turn the transmitter on first, then power up the reciever, otherwise you could have a servo go "fullover" and strip gears.

Other than that, good job.

stonedeaf, not to avoid answering your questions, but it sounds like you might want to get in contact with someone familiar with the hobby. Maybe your Local Hobby Store (LHS), or a local club that can provide direction. However, for your answers, to your questions.

The screw on the servo is for holding the servo arm in place. There are holes in the arm for inserting your pushrods using either a 90 degree bend and a quick connector to hold it in place, or you can place a "z" bend in the rod and wouldn't need a connector. On the other end of the rod, you screw on clevis's which attach to the control horn. The mechanical adjustments that are indicated are done by moving the clevis back and forth until you get the control surface as close to the neutral position as possible. The rest of the adjustment is done via the radio using the 'sub trims' and the 'servo travel' settings.

As far as attaching the hinges to the wings and stab, you use the ca hinges supplied in the ARF. By inserting them in the wing and then in the aelerons and making sure you have only a small gap between the wing or stab, and the control surface, you then drip in CA glue. The glue will then run along the ca hinge into the wood and spread out allowing for an area of glue that attaches the hinge to the wood.

This is pretty general and does not contain the total detail needed to put all of this together. If you do have the ARF and the instructions for the Avistar they do have much of the steps outlined. As indicated though, you might seek local help that can show you or demonstrate the techniques, or walk you through building your ARF.
