Calling all BeastX 700 owners- advice pls

[alex]

My 700 is flying OK, but I am finding it impossible to get the blue light on at 6 degrees of pitch during set up- it lights at about 7.5 degrees of pitch and I cannnot work out why.

I have the RJX head, standard Align shaft and have put the RJX balls on the swash as the RJX ball links will not fit the Align balls. I have got the metal Futaba/ALign servo wheels with the linkages on the inner ( shortest radius) holes.

Any ideas please I am hoping I am missing something obvious.

Thanks

Alex

There might be no need to do this as freakware reckon it is more important to make sure that the 6 degrees is there and not necessarily the blue led. This is just an indication that your head setup is perfect for fbl. If you still have the need to do it then your going to have to go further in on the servo arms.

It's more important to get 6 degrees than a blue light. I'm using the 4 finger star horns, on the third hole from centre.

The trouble with having a red light is that you are not using the full range of servo travel. In other words, on a roxanne (red light ) instance, 100% cyclic may only need 50% servo movement. This ,means the resolution is low and potentially not as accurate (why measure in cm steps when you can measure in mm steps?)

Mine's not a 700 obviously, but I faced the same predicament on my Vision 50 Comp.

I take it your measuring the actual blade pitch instead of the swash plate pitch? I made this mistake to begin with.

u can always give it to me for a weekend cant wait to see it, lol :P

One problem with moving the balls in on the servo horns is the links will no longer be parallel. This does actually matter and you could end up with the linkage system binding. To keep the geometry correct it is also necessary to move the balls back from hte centre line to maintain a 90 degree angle of the link on the horn.

In the picture you can see the balls are not on the centre line of the servo horn.

It would be better to move the ball out on the blade grip. I have seen some parts somewhere for doing this but I can't remember where I saw them.

As stated, it is better to adjust the ball on the blade grip arms to get more pitch movement but actually going more than 6deg does no harm, at the moment i've got mine set to 7.5deg after trying 6deg & all i found is that the heli rolls faster with 7.5 than 6. So 7.5deg gives me the roll rate feel i like & it's been like this for about 50+ flights

Yep I just moved the ball on the blade grip, sorted :-)

How?

Sorry to sound thick, but I cannot see any way of moving the ball on the RJX blade grips- it can only be moved laterally that I can see. I may just go back to 7.5 degrees.

When I set up my 500 FBL, moving the servo linkages in solved it and it blue lighted easily, but the mechanics on the RJX head do not seem to adjust enough.

I need to get this straight in my head- does the Beast X put a blue light on when it thinks it has moved the servos a certain distance? If the blue light comes on at 8 degrees, does this mean that the pitch is actually increasing too much for a set servo throw, or is the blue light a short fixed distance of servo throw that should give a minimum of 6 degrees?

Or can you fit shorter balls on the inner swash ring or longer balls on the outer swash ring or both. That will reduce the cyclic input to the blade grip without reducing the swashplate deflection, therefore effectively improving resolution.

Only had 3 flights on mine up to now, but its working ok.

I had the red light on when i set the 6deg cyclic. I believe the beastx needs to know where 6deg is to calibrate its geometry (someone may be better at explaining that one). It flies well and its really steady. I am using Align FBL servo discs, mikado head conversion for 700 and using the Tx settings (set on the beastx). With the Tx settings, i can now adjust my aileron and elevator end points to suit my cyclic speed needs. At present, there set to 120%, but as i say, i'm only 3 flights in and still 'tuning' it.

I've got mine on extreme and like the way it feels, but I may set it to Tx and play around with EPAs and expo.

when i set ur 500 up, i didnt check lights, i just set 6 degrees

[Cuppa]

Mine set up easy peasy, shuffled the align metal servo wheels to get spot on 90 deg to servos at mid stick, all square and parallel no pitch, expo in TX @ 15%, 8% on the tail. suits me fine at that for the mo.
