Swashplate Level tool

I think it is handy but I have not used it. Has anybody used it and share your thoughts?

I had someone that had one help me level my swashplate. The way it was used was to remove the hub assmembly then slide the swashplate tool on the shaft. set on the 3 servo link arms. Now you can turn on radio (with motor disconnected) center sticks on TX  and sub trims. plug in battery to heli. Turn TX  back off. diconnect battery on heli. Now you can adjust linkages and servo arms to match the leveling tool. wow what a difference then using the eye.
hope this helps

theecoop, dDoes it look like this one? I found Grandrc sells it for about $15



Here are the instructions on how to use it.

Instructions:

1-Place the swash plate leveling tool on a surface known to be perpendicular (90 deg.) to the main
shaft. This can be the upper main shaft bearing, the upper main shaft collar or the top of the main
rotor head. In some cases, the head button will have to be removed if using the top of the main rotor
head. Place shims under struts and/or skids until both levels indicate helicopter is perfectly level in
both directions.

2-Move the swash plate level now on top of the swash plate. It may be necessary to first remove the
main rotor head and washout assy to provide adequate clearance for the swash plate leveling tool to
be inserted.

3-With radio system on, set collective to mid-range of travel. This will near 0 deg for a 3D set up or
near 2 deg for FAI, Scale or beginner set up. Adjust linkages going to swash plate as necessary until
swash plate is level in both directions. (NOTE: If you're using the swash plate leveling tool on a
helicopter that has been flown and trimmed for flight, it is common for the swash plate to not indicate
level. This is due to the offset trim necessary for tail rotor anti-torque and center of gravity and
horizontal fin selection.). Raise collective stick to full hi Pitch  position while observing both levels on
swash plate leveling tool. Repeat above for full low Pitch  position.

4-If movement is either or both directions is observed, first check for mechanical linkages that all
should be perpendicular (90 deg) to the servo output horns. If all are found to be correct, this
unwanted movement can be electronically mixed out by activating an electronic mixer now found in
most transmitters. The most advanced transmitters now incorporate mixers with multi point mixes
that can be curved similar to a Pitch  or throttle curve. This is the best choice for correcting the
unwanted movement in that the amount of unwanted movement will vary by collective stick movement.
Set up mixing so that the collective is the master channel and the Roll  (ail) or fore/aft Pitch  (elev) is the
slave. In otherwords, when ever the collective channel is moved, it will automatically mix in the
appropriate correction to offset the unwanted movement. The center point of the mix will be the center
of the collective system where you first leveled the swash plate.

5-With swash plate level on swash plate and mixing function active, repeat step 3 and add correction
in mixing function as necessary until swash plate will remain level through out it's entire range of
travel.

For more advanced set up and flight trimming check out FMP's Ultimate heli setup tool. This tool
used in conjunction with the swash plate leveling tool will provide the most accurate setup and flight
trim available today.

I'm with Ant.

It seems that a cyl the same aprox. dia as the upper swash bored to the shaft size would do a wonderful job of squaring the swash to the shaft.

OTOH I haven't bothered to make any as...If your servo links are the correct length the swash is automatically level....After the flight trimming is done I always wind up with a little tilt on the swash to compensate for the tail rotor thrust.

Admittedly never trying one, I have the personal opinion it's in the same league as a skid alignment tool.

Skid alignment tool!!! That one has passed me by Steve !

I just have a nice Pitch  gauge and you soon get an eye for setups once you have done a few but sitting the heli on a table is a must, unlike some I have seen trying to set them up on the floor !

Setting a heli up on the floor? OOH I couldn't afford that. I'd have to supply a helper with beer. When I finished setting it up he'd help me up. Yep Gimme a work bench over a swash leveler, or skid aligner any day.
