Beast x and G4

Isn't it smaller arms?
It's a beastx just fly it.

Never had a problem with the 5 I have done on my models

Well unless its a really bad vibrating model when it feels drunk and try's to roll left and kill its self

If you've got blue light and 6 in J that's good, L if I remember correctly is cyclic limit, just set this until no binding at all cyclic limits and you're good to go. L just teaches the Beast the max available cyclic throw and as long as there's plenty, which I imagine there must be on a G4, it's not so important what light you get here, 6' on J is more important.

hmm, ive always thought the other way round George, its the 6 degrees thats important and not the colour of the light but it is important to get as close to a blue light as you can in with the cyclic limit?

6' and blue in J means you've got pretty spot on geometry and is more important, light colour in L is not so important as its just setting the available cyclic throw, have a read of this from Stefan at Beast..........

For Point J:

Here you teach the MICROBEAST the servothrow or better say the relationship between servothrow and deflection. If the LED is blue, than this is a sign for you that everything is okay. The resolution is sufficient and you should reach enough maximum cyclic deflection and hopfully also enough collective pitch.

If you get 6° earlier - red or purple - there is something not okay with your geometry. The servo only does little throw but already makes big deflections. This is not good for the control mechanism because it will always tend to overreact.

If you get 6° very late - long after blue - this is OK when thinking about resolution. But this indicates that your Servo is already doing a huge range of throw and there will not be much left for getting enough maximum deflection like 12° or so. This maximum deflection is needed first of all to get enough rotation speed but more important, to give the control mechanism enough room to work correctly. Because when doing maneuvers like highspeed flying or retaining the heli you can't see this but the system will work in this range.

So this leads us to point L:
When you understood the above you now see that this point is just for safety reasons. It is always necessary to get as much throw as possible. On the ideal Heli you would not need to limit anything, the servos can work in their full range and the Heli has so much cyclic deflection that the MB will never use this deflection.

But in reality there are often helis, that do not allow this much throw because the servo linkages or the swashplate will bind at some point or the ruderhorns will bind at the mechanics when giving full coll. pitch and full cyclic. To prevent this binding and in consequence burning up the servos when in flight you can limit the servothrow, so that under no circumstances the system will steer over this limitation point.
The limitation is working in a cyclic ring manner (it is not a cyclic ring function!) and as said always try to get as less limitation as possible otherwise the system may not work correct and also you cannot achive the maximum rotation rate.


Short note at the end:
The rotation rate can only be adjusted by the transmitter. It has nothing directly to do with point J or L. But when there is not enough cyclic deflection you can of course not reach the maximum rotation rate, similar to a tail gyro

Hope this helps Tony!

HI,

Slightly different question, but still to do with Beastx and G4. I am just about to start the setup on my new G4 with a beastx, I already fly a beastx on a Velo 50 and a Trex 500 and haven't had any problems and I'm familiar with the unit. My questions is which swashplate mixer setting (menu point H) are you guys uses 140deg (blue flashing) or 140deg 1:1 (solid blue) or have you set the swashplate geometry using the PC software to 135deg and then I guess used the Off (black) on the beastx.

Thanks in advance

Set mine to solid blue, blue flashing you get unwanted colective input with cyclic input, can you actually set it for 135 in the software?

Just to add into mix, too much resolution will be effectively making the servos slower as they are having to move more to acheive the mechanical deflection. How much one would actually notice this, I have no idea.

Well i rectified the problem with the align fbl horns which have a larger ball spacing, blue lights on J and L, so im happy now.
