Default Swashplate leveler

Has anyone had to level there swash from the start? My servo arms are all at 90 degrees, and at mid stick my follower arms do not appear to be level, a bit high and my swashplate seems like it is high on the main shaft.

I just bound the TX to BX and made sure a-f are correct colors.Before moving to step "G" the arms were all 90 degrees. I never entered step G or rested on one of the colors because the servo arms were perfect.

Should I go into menu G and rest on one of the servo colors and try to get the swash and follower arms level at that mid point?

I'm asking because I have the blade swash leveler and at mid stick I have a good 4mm from the bottom of the swash to the upper bearing block. Is this normal for this stock setup?

What are you guys using to level and set the correct height for the swashplate? The swash seems tilted to the front a little also? I can't find a good reference point to get this set.

If you have the swash leveler tool from blade then it's simple.

1) Go into Setup menu point G, or parameter menu point A (either/or)
2) unhook the lower links
3) Slide the swash tool under the swash, so it's resting on the heli frame
4) Jiggle the tool a little so that the wash bolts/bearing are resting in the cut-outs in it, the plastic part of the swash should be laying flat on the tool
5) Adjust the ball links so that when you hold it against the ball on the swash, it doesn't move the swash
6) When done, you should have a level swash
7) then adjust your upper links so each blade is at 0-pitch

If I was industrious, I would take a video showing how to use it. It's really pretty easy and better then removing the head like other levelers. Unfortunately I am lazy at the moment. Maybe later this week

I still have no clue what the measuring part on the side is for. I guess to check arm length?

Setup menu G (not Parameter menu G) is the swash-level step. Use it to get the servo horns at exact 90-degree angles (subtrim essentially) with the swash links off. Then put the tool under the plate from the back, set up your links as noted by Kumba, pop them on to be certain (you should be able to slide it a little fairly easily, but not roll it at all from side to side or front/back or have a noticeable light-gap between it, the frame or the underside of the swash), then pop at least the back two off again and lift to get the tool out. From there, reattach the links and use your bevel box/pitch gauge to get the blades individually to zero pitch by adjusting the swash-pitch links (mine came with positive 4 degrees out of the box, apparently).

A-F do NOT keep the servos at their midpoint, which is where the swash needs to be level (and at the right height, which the tool also sets up for you if the swash is flush against it). Also I don't go past point G with the leveling tool still under the swash; some of the later options will crank it one way or another (like the last one does, setting piro optimization) and bind or possibly even strip gears out if it's there. I think you could go zero-stick on point I (swash servo directions) which should lift the swash off of it and allow removal.. assuming the swash is moving properly. I still wouldn't, when it takes five seconds to just pop off the swash links.

It really does remove a lot of guess work for $8 even though some don't like it. It all boils down to preference. Also pretty nice since you don't have to remove the head to use it.

Ok guys, With the swashplate resting on the leveler will the follower arms be level?
Every time I finish going through the full setup I end up with different pitch settings for high and low stick.?

The follower arms should be making nice 90-degree angles with the servo-swash links off and the leveling tool in place.

You set your positive and negative max pitch in one point of the Setup menu. The BX unit may not be *giving* you the full pitch ranges once you're out of setup, especially if you're not in TX mode... and I find that it holds a little back even then. I'm guessing for max-pitch/cyclic stabilizations.
Also when you exit the setup menu and are in 'ready to fly' mode, I've noticed that the swash leans to the right on mine (assuming to counter some of the tail side-vector thrust, but I don't know; just did a post-crash setup and am waiting for a calm day to try hovering it). Could be giving you weird readings as well, get 4 degrees at mid-stick on one blade, and 2 on the other. But going back into Setup-G, they both read perfect.

Since this is my first electric heli, I found some setup things the hard way.

Most important is disconnect the motor when setting up the bx! Ask me how I know.
Hitting the last menu light in parameter mode the blades started to spool up WTF! lol

Even with throttle hold engaged?

So, when you enter setup menu G the servos automatically center? How would you know they are centered? I assume once they are centered, you screw the arm on closest to 90 degrees as possible then proceed to screw/unscrew the linkages from the top or bottom of the linkage?? And then adjust your linkages to the grips to set 0"ish" pitch?

Exactly. Also, once you screw the horns on, if they're not exactly at 90, you can make final adjustments by selecting one of the servos and moving it with the elevator stick. Make sure once you are in menu g, switch to one of the servos (led will be lit) and make sure the led is lit when you go on to menu item h.

There is a good video showing the entire setup, in the beastx forums in the sticky section.

Here are the individual setup videos for BeastX - He did a great job explaining why you're doing these steps. I'm a heli n00b and can do the whole BX setup from memory now
