I've been researching this and I've seen the tools with the slots that rely on the frame tops being true, and the swash levels with little bubble levels in them. I've also read up a bit on leveling the heli, locking the flybar, different gauges and methods etc, for setting up pitch.

It seems to me that what is really needed is a method to reference the main shaft to true vertical and then level the swashplate with one tool.

What about a tool that clamps to the mainshaft (like a keyed split collar) with a "V" to fit different shaft diameters, has a flat perpendicular circular plane on top to level the swashplate to, and has a long arm on one side to support a precision level like a Starrett or similar. This way the arm could be leveled in two positions 90 degrees apart locating the mainshaft to a true vertical reference, and then the swash could be leveled to the tool.

Does anything like this exist?

Could anyone here design and machine a run of these as a member group buy? Would anyone be interested?

Or is this a worthless idea?

Swashplate leveling tools aren't needed unless you have ccpm. If you have that then a regular bubble level works well.

How do you center your cyclic servos and set up your linkages without a level swash?

Laser Level...

Defferent use, same concept.

http://runryder.com/t227064p1/

Set up the level and shoot the mainshaft, then you wil know if it is perfectly vertical. (You would have to shoot it twice 90 degrees out) Then you could level the swash the same way???

Idle minds....

I tried flying upside down once... but I couldn't take the blood rushing to my head.

Bench set up will get you very close - the better the bench set up the closer you will be...

to get the exact set up you will need to fly the heli. A good hands off hover is always the "level" set up.

Here is a thread on the same subject with several great ideas. http://www.runryder.com/t229570p1/ I like mine, but I'm not biased at all.

Yes maybe that is the way to do it Jkos. Level it all as you assemble it then set it all up. I can see squaring up the mainshaft while it is bare without much trouble, and then installing and leveling the swash with the dial indicator next, and so on.

i have been thinking about this too. i owm a machine shop so i have measuring equipment. to set up my blade cp micro i have made a fixture that holds the heli solid and allows me to locate the main shaft exactly perpendicular to the surface plate (large granite slab that is perfectly flat) with the use of height micrometer and a indicator. so, you can take this height mike/indicator and move all around the heli and verify if the tail rotor shaft is perpindicular to the main shaft, if the swash is level, if certain control arms are level etc.,etc.. your not going to be able to do a more accurate job than with this set up. the problem is its gonna cost a couple hundred bucks atleast to buy used stuff.if you hunt you could find some chinese cheapos. also you can check for zero pitch angle from blade to blade and paddle to paddle. it really puts "the writting on the wall" when it comes to quality of the components. the problem i see with some type of a fixture that clamps on to the head or whatever is making it universal and it would have to be a precision peice. so unless one was to go into mass production it would be expensive. i just purchased a t-rex with all the cnc doodads and am excited to see what a "perfect set" up really means.

"perfect set" up
I'm a toolmaker too so when you get there let me know because I've been dying to figure this stuff out since 77.

I've always wondered how you could get a perfect set up with components made of plastic, aluminum and steel. With the different thermal expansions and contractions how long would it stay perfect?

Both K&S and MA make a swashplate leveling tool. The KS is a round disc with a slot for going around the main shaft (it has a rare earth magnet to keep it in place on the shaft) and the MA part is a disc with a hole in the center (uses a thumb screw to lock it to the shaft). You can use the K&S part with the head on the heli but the MA unit requires the head to be removed. I've used both and found them quite useful and very accurate.

I used JKOS's method with the dial indicator the other night. It works great. With my raptor 50, it would have helped if I had raised the main shaft up an inch or so in order to get the dial indicator better aligned with everything, but I didn't bother.

All this "leveling" is a big waste of time. It doesn't matter if the swashplate is level, what you want is the swashplate to be PERPENDICULAR to the mainshaft. The dial indicator method accomplishes this without the wasted steps of leveling your helicopter in 19 steps.

dial indicators and stands are pretty damn cheap from harbor freight tools so nobody in this hobby has an excuse not to have one.

I got a fever! The only prescription is MORE 6HV

What I love is,,,, after you've got the swash plate perfectly level with zero trim & zero sub-trim, you fire up your new creation for the first time and lift it off the ground. You realize that it's "coming at you & fading to the right. So what do you do ???? You land, pop off the links & lean the swash plate a little forward & a little to the left. Why'd I spend all that time getting it perfectly level ????

If God had meant for man to fly, he would have given him more money

If you fly eCCPM machines, it is important to know how your swashplate behaves throughout its travel. Starting with a swash that stays perpendicular is a great place to start. I've had several helis come off the bench and require zero trim.

crowfly is exactly right. You can't get a pefect setup. Anytool that you buy will get you in the ball park. You have to take off and fly the dam thing to get the setup correct.


CCPM setups you have to get level just to make sure that there is no interation. Regular swashplates you can just eyeball.

Is that common practice?
