GUIDE: How To Level your swashplate

by lovetoflyguy » Thu May 17, 2007 6:51 pm

Since I noticed several inquiries about swashplate levelling, I have been inspired to write a 'how-to' article. Enjoy!

I'm not sure if this will apply to other helis, but it should help anyone who owns a King or Cool. Also, I'm aware that there are several different levelling tools out there, but they should all work about the same. I'm using one designed for the Trex...

Here are a couple photos of the levelling tool that I will be using: Image
Image

First, remove the upper "Jesus bolt" and nut, and put them somewhere safe - in a small bowl or something.

Image

Next, carefully disconnect the four ball joints on the swashplate, noting which one goes to which - I used a little of my wife's fingernail polish to mark them (Don't tell her!). You should now be able to easily lift the rotor head assembly off. If it doesn't come off easily, make sure you disconnected all of the right joints...

Image

It should look like this when you have the rotor head off. The arrows below point to the spots where the 'feet' of my levelling tool will rest when it's installed. Note - they will rest on the swashplate itself, not on the links.

Image

Before you slide the tool on, we need to find out what your heli thinks 'level' is, so powerup your Tx, making sure your controls & tabs are all centered, disconnect the motor for safety, and powerup the heli. The servos should center themselves. Now, slide the tool down the rotor shaft, line it up, and check for gaps.

Image

If you see any gaps, remove the tool, power down the heli, and adjust the three servo linkages as needed. Now power it back up (your Tx should be turned on throughout this process), reinstall the tool, and check for gaps again.

Image

Repeat as needed, until there are no visible gaps...

Image

Congratulations! Your swashplate is now level!

Now all you have to do is put it back together! If you decided that you wouldn't need to mark the balljoints as I suggested earlier, you may have problems at this stage - don't say I didn't warn you! :)

LTFG,

Very useful. I have just leveled my swash - sort of. I set up the levels with the swash at half-stick and got it spot on - however at maximum positive and maximum negative the front swash-plate "shoulder" (the bit that the leveller sits on) is now out of adjustment. Is this an End-Point-Adjustment issue or do I adjust the maximum and minimums on the Swash menu ??

Cheers,
Mike.

FOUND IT 8) 8) 8)

By adjusting my end points EPA setting I now have a flat swash throughout :D :D It seems to be proportional thoughout so is falt all of the way up and down.

The swashplate how-to-a question:

by DKellett » Sat May 19, 2007 3:35 pm

I have a Honeybee KING and I am new to all this but will be doing the leveling (using the same leveler pictured in your SUPERB How-To) in the next day or so. You did not mention any detailed procedures to follow if any of the 3 servo arms, upon allowing the transmitter to 'center' all linkages, are NOT at 90 degrees to the pushrod or at 90 degrees to the servo.
Please advise.

Please advise.

You want the arms at 90 degrees to the main shaft - this way movement in both directions will be equal (get them as close to perpendicular as possible) to do this just undo the screw in the middle of the arm, pull the arm off the spindle and move the arms up or down by a "notch" - the arms are splined. You will normally find that they will be just above or just below 90 degrees - just make sure that all are the same (i.e. all just above or all just below). I then set all of the links to the same length and check with the leveller.

Cheers,
Mike.

A question: How bad is the swashplate configuration normally when the heli (I've bought a Honey Bee King 2 if that matters) comes out of the box? Or is this conf. very different from one helicopter to another? Can you be lucky and only need to use the trims on the transmitter to calibrate the heli in a good way?

Thx for the help =) And yes, i'm a noobie with this sort of things..

hi john
the leveler will work with any heli as long as the shaft diameter is 4.9-5mm.

When I leveled my swash I also checked to see if the swash remained level as it moved up and down the mainshaft. Mine did not and I had to tweak my servo adjustments for a level swashplate through out its movement up and down the mainshaft. It results in me having to use less trim on the Tx for a level hover and flight. I am using the stock Esky Tx which provides no subtrim adjustments. Just as fun to fix as it was to finally track down.

If you are not flying in 3d mode yet, do you still level it with the throttle and trim at mid level or do you level it with the throttle and trim completely down?

I do mine with the throttle at mid stick and the throttle trim all the way down. This is with the Tx in the idle up mode (motor disconnected).

When I levelled mine I just had the throttle stick all the way down.. Does anyone know if it differs any if levelling it in idle up with about 50% throttle, as macdaddyec suggests?

Re: GUIDE: How To Level your swashplate

by mrforfun » Tue Oct 23, 2007 8:12 am

I have just received the Trueblood swash plate leveler and did not realise my eye was so bad - the plate was very out of level. I have now leveled the plate and found that when attempting to take off and hover the front of the honey bee lifts up and the honey bee sits down on its tail. I have tried triming to no avail. I have set the tail rotor pitch and adjusted the pitch on the main blades. Could it be low transmitter batteries ?

PS how often do you need to relevel the swash plate ?

Thanks in anticipation
