AR7200BX setup problems ..

[smuir00]

Hi, i am trying to setup an AR7200BX on an Align Trex 500 ESP

I am using Hitec HS-5245MG for the cyclic and Futaba S9257 for the tail

I have set bound the unit to the transmitter (Spektrum DX7s) and started through the setup sequence.

Have got through to (I), when i raise the cyclic 2 of the 3 servo's move correctly but the 3rd does not move, as i choose the different options the servo that does not move changes between the 3. But, they do not all rise and fall together.

If i go on to (J) the blades do not start at 0 deg (even though they were set up previously on (G))

So a bit confused.

I have 2 other BeastX units on a Trex 550 & Trex 600 both working fine.

Any ideas appreciated

Thanks

Sounds like the mixing selection is wrong. I would check the firmware level and find the latest manual for that version as the menu changed with subsequent versions, also make sure that mixing is off in the Tx, I'm sure you've checked this but worth making sure.

Have you maybe got 120 Deg swash mixing set up in the Tx?.. You must have swash mixing disabled in the Tx which on Spektrum is either 'Normal' or '1 servo' (cant recall which off top of my head).

Hey buddy.

As with the above two posts, if you have any swash plate mixing in the transmitter set it off or just the simple 1 servo with Spektrum.
Then in the beastx settings, do you have menu H set to give a solid red led which sets the beastx mixing to 120 degree eCCPM;

Setup menu point H - BEASTX Wiki

Also worth checking you have each servo plugged into the right port on the Beastx, I don't think it's the cause of this problem, but having been there this can cause funny things.

I swear I've read sometimes some unexplained problems with the Beastx can be fixed by resetting it and going through the settings again if the mixing settings are correct already.

when i saw the replies here I knew what i had done (or more to the point, not done !)

The Tx was set to swash 120 deg, so after setting it back to type 1 then it all fell into place and worked as expected

Thank you all .. !!
