Swashplate leveling

[torch8]

Regarding ccpm setup or swashplate leveling.

If swashplate is too high on main shaft, it'll result in less positive pitch and too much negative pitch and vice versa if its too low?
Or do you level swashplate at mid stick and position midway from top and bottom of main shaft so you get equal collective up/down

The first thing you need to do is level the swashplate at mid stick. Then, using travel adjust make sure it stays level at high and low stick.

You want to pay attention to make sure the washout block is not hitting the head and causing binding.

Thanks. On the Travel adjust part, adjust the pitch?

[newbheliusr]

No, the travel adjust part only makes sure the swash stays level at the top and bottom. If the swash sits too night on the shaft you need to shorten the links that go to the servos.

Perhaps I misunderstood what you meant.

Just for fun, what heli is this for?

Its for Walkera M120d01. I had swash level midway from top/bottom of mast. However not getting enough positive pitch on it and my linkages to blade grips are already max out.

I had no problem leveling swash, when I am using beastx on my Gaui 200. Then again the beastx allows u to set max/min collective in step k.

Guess questions is common to set swash higher/lower or is it just personal preferences and just to get it symmectrical?

[newbheliusr]

If you aren't getting enough travel you can adjust your swash mix pitch setting. On my 450's the more you add to the swash mix the more travel the servos have.

I have no experience with Walkera at all. I aplogize.

No problem, thanks anyway. I just to have play it more, as the mechanical setup on the 120 size heli is a pain to work with (small linkages).

Long story short, yes if your swash is level at mid, high, and low and you've adjusted your swash mix to get say 8 deg at high and your getting 9 ro 10 at low, then adjust all links equally and raise your swash and vice versa if your getting more at high than low. That way you should have equal amounts of pitch at high and low sticks. However after raising or lowering, make sure that everything is level including your washout arms, and flybar cage. All that good crap. Watch Finless' videos and you should have no problem.

Whats up guys gott a quick question to make sure I got this right b4 i try it out. So I leveled my swashplate on my trex 450 level it al mid stick first then made sure it was level all through its travel, it's prefixed all the way around.(: so my question is with the stick at 0 no throtal when I give it throtal making the heli lift should the swashplate go down? Hope for some help thanks John

The swash should go up, if it's going down you need to reverse it in your transmitter.

[Jsilva67]

Ok that's what I thought so under swashplate in my dx6 just reverse the swash

Level swash plate first. Then at mid stick do a zero pitch setup - position midway from top and bottom of main shaft so you get equal collective up/down

Perhaps the following has not been mentioned:

If you radio displays how much pitch you're imputing on the collective, go by that reading and do not rely on aligning the notches on the Tx stick with the case. Some radios display will go from 0 to 100% fifty being mid stick, others go from -100 to + 100 with zero being mid stick.

You should have the servo horns and washout base as close to 90 as possible on mid-stick. Proper head architecture makes everything else flow more smoothly.

Whether your swash goes up or down for pos. or neg. collective depends on your main blade grips:

Leading edge blade grips (like Align), swash up is positive.
Trailing edge blade grips (like some Walkeras and mini Titans) swash down is positive collective.

Once about to fly, you should be light on the skids or hovering at mid-stick. Later on you'll notice the smoother the transition from ground to air will tell a great deal about your mid stick setup.

Hope this helps some.
