swash leveling

[shaggybirdman]

when do you level the swash plate. i watched finless's ccpm videos, but he never showed, or talked about using a leveler, so i ask....

1) setup the servos
2) setup the servo arms
3) install the balls
4)check, and eliminate swash binding, and set washout block clearance.

is this when i'd use the swash leveler, and reckeck the swash movement then follow threw with the video? remember i'm setting up a 450 x cde with mechanical ccpm. i'll post pics tomorrow. hope you understand my question.

oh ya rc hover has a nice leveler for the trex. just got mine today, so setup will begin tomorrow after i pot up some plants. berry bushes, and a coral bark maple. ya wrong forum, but thought i'd share my hobbies. i grow bonsai as well.

here's the link to it. i hope it's not concidered selling, or anything.

Oh, he's talked about swash levelers alright. Just do a search for "Finless" and "leveler" here in the forums. He thinks they're a waste of time, so I doubt you'll ever see him do a video about using one.

I've never used one and mine fly's perfectly!

Never used one either. The ol' Mark-I Eyeball and a digital caliper (if I'm feeling particularly anal that day) are all you need. Hell, even a small ruler will work.

hi guys,i'm a noobie as some are aware!!! and i was also thinking about swashplate and its relation to whats called the washout block,as i'm still trying to figure everything,is there a blow up picture or diagram on the boards that you can study,thanks guys,bob

good bad or indeferant where along in the build do i use it is all. i got mine, so i'm going to use it. hell $16 to my door is cheap enough. ruler, or a digital caliper seems way more than the $16 for a leveler. maybe a bit more work to use it, BUT still when do i use it in the setup procediure is all?

You use it after you have your arms at 90 and the end points are set without the head on. You'll then plop it on 1st check center stick level, then high and then low point using ATV adjustment to make it level on eash end. Put head on and you're done. Forget the stupid bubble thing Finless does. Waste of time as long as the rest of your head is at 90 center stick.

Some like to eyeball this, it only take a few minutes to use the leveler and you won't have to question your set up once done.

Good luck

You didn't mention which heli you're setting up. If you are working on a Trex 450 make sure the level swash is 10mm above the main bearing block at mid stick. Your max and min pitch will be uneven if you don't do this.

A way to check for swash level that I have used and works pretty well is this. First, stuff something in the flybar teeter slot to keep it level. Although not really necessary, it's just one less thing to mess with. Put a pitch guage on one of the blades and leave it on that same blade for the duration.

To check for level in the elevator direction (fore/aft tilt), put the blades in the left/right position and measure pitch on the left side and make a note of it. Let's say it's +3. Move that blade around to the right side and measure pitch and make a note of it. Let's say it's -1. The difference between them is 4. The high side of the swash is 90 deg farther around in the direction of rotation than the greater pitch. So that would be 90 deg farther around from the left side, the nose. If we take half the difference between the two measurements, 2 deg, and subtract that from the high value (3-2) or add it to the low value (-1+2) and preset the pitch guage to that value (1 deg), and adjust the swash to get that value with the blade at either the right or left side, then the swash will be level in the fore/aft direction. Likewise, measuring the pitch with the blade in the fore/aft direction and applying correction to the left/right tilt of the swash. For a final check, the pitch should be the same at all four stations.

Another way to do the leveling, which I have not tried, is simpler because it doesn't even require a pitch guage. I'm not sure if it's as accurate but here it is. Set the blades left/right and fold them back around 90 deg so they're over the nose or tail. If the swash is level then the tips of the blades should be the same elevation above the bench. If the tips aren't even the swash is off in the fore/aft direction. Swing the blades over the left or right side to check the left/right tilt.
