I wanted to share how you can make a simple jig that will help get your servos at a near perfect 90 degrees. (I was struggling with CCPM interactions).

Open Microsoft Paint or you favorite paint program and draw a horizontal and vertical line. (Tip : If the lines are straight and not stepped they are perfectly horizontal or vertical.

Print the image

Take a clear piece of plastic and cut it into a rectangle big enough to cover the top of your servo (I got this piece from a toy wrapper)

Tape it to your printout

Using a ruler and a sharpie and trace the lines onto the plastic

Put a hole at the point where the two lines intersect big enough to put the servo horn screw in

Connect the servo to the receiver and set the sticks for their center positions with no sub-trim. Put the servo horn on the servo at the approximate 90 degree mark (servo balls not installed). line up the line on the jig with the holes in the horn. The perpendicular line will clearly show you if you are off or not.

Use subtrim (or servo programmer) to adjust the alignment until the line runs down the center of the servo

Well thats it. I hope this helps you out. It did help me.

Now this is what I am talking about... Something useful for once! Not a topic about what color Speedos CY had on in their wet dream!

Excellent tip!

May I offer a suggestion? use a straight edge and something sharp to scribe the line deep and then wipe over with the paint marker so you get a finer, more crisp line.

It is innovative, but is it really necessary?

It really helps with getting a good setup quicker. Especially if you are new to the hobby. (That is why I posted it in the beginners section )

I spent hours trying to get rid of ccpm Interaction "eyeballing" it on my trex 450 pro v2. (The servos are mounted in such a way it is hard to eyeball it once mounted.)

This corrected it in about 10 min.

I figured as much when I saw it in the beginners section. I have a 450 pro too and I know what you mean. I just thought of a suggestion. Instead of using a marker, you can use pin striping to make the lines crisp and straight.

Next im going to use the same build concept to make a jig for my push pull links on my X50.

The center refrence line just has to be long enough to reach the center of the belcrank. Same basic alignment procedure as above. When the refrence line, lines up (covers) with the center the belcrank on the oposite side its square

Aren't Speedo colors are at least as important as perfectly aligned servos? If they are the key that CY uses to fly well, maybe they'll help me too.

Here is another one I made for the Push Pull setup using the same technique. I just held it up against the servo to take a quick picture but you get the idea.

Not square

square (well kinda my hand slipped )

now remember, servo arms have an offset degree per each arm from 90 degrees. So in the pull pull setup it may not be fully effective. But it gets darn close. Ill give it a thumbs up for a great job and tip for setup. I will consider using it now!
