MSH brain and transmitter modes.

[Cobradave]

I normally fly beastx but have just got a mini protos which comes with MSH brain. I am trying to set it up and can go through all the settings on the pc without issue, however the transmitter controls do not align to the actions on the heli. I have followed the diagram with servo 1 going to 1 on the brain etc as per the diagram etc. I am using 2 dsmx sats onto dx9 Tx. What I have worked out is the controls mirror my Tx being mode 1, when in fact it's mode 2. So elevator control seems to be operating throttle and vice versa? I assume I am missing something really simple some where, anyone come across this, got any ideas?

Sounds like you have got wrong wire in the brain Ports, just go over it again and make sure you have picked the right diagram to follow in software, I've done it a 1000 times, so your not alone.

Hi, how are you keeping? Your 500 is still flying. :-)

Help me me spot the obvious mistake. I am following top diagram on PC screen, servo one at the front of the heli goes into servo one on the brain, servo two looking from the back the one on the right goes into servo 2 on the brain, and servo 3 is the one on the left looking from the back going srv3 on brain. Tail is into tail, and esc is into ch1 as per the diagram?

Apols, photos have come out upside down when uploaded for some reason ?!
thanks

Make sure your swash type (in the tx) is set to basic 90 degree one servo, so normal on dx9.
Menu 5 of setup your stick actions SHOULD match what it shows on screen, you might need to reverse channels in the transmitter so that directions are correct. Presuming you have selected the correct swash type in menu 6, and that your stick actions DO match whats shown in menu 5, you will need to click the servo reverse button on the left hand side of menu 7 until the swash on the heli matches your stick movements, give it a few clicks and move the cyclic stick. You should be able to get everything to match there, if not its possibly wiring

[crash-test-tomo]

Your wiring sounds right dude

[Cobradave]

Your wiring sounds right dude

Yep, when you put the stick movements in on transmitter you get the right movements on the PC, had to reverse channel elevator and rudder, but pitch throttle etc was fine, done travel settings etc, so looks ok on PC, but is not translating to heli, it reacts correctly if I was using a mode 1 transmitter? Have done the servo arm 90 degree setting screen as well, so they are reversed where necessary on that screen as well?

Im not sure where you are going wrong then dude?! Long as the brain swash type is h-3 120 degrees aswel then your setup should be correct... I would say possibly transmitter?
Check system settings and make sure you havnt selected mode 1 somehow? im not sure you can reassign the channels without switching modes?!
Have you used the tx before?
Maybe someone a little wiser has an idea?? Lol

Hi, I have been having a similar problem eventually I started from scratch and everything now seems to work in the correct way.
First I am using a standard Rx setup using JR DMSS Rx, Synergy N5c.
I completed the setup as you describe with the diagrams using servo 1 etc. However I realised that servo 1 is the elevator and on the JR receiver this is not output to 1 on the Brain so I changed over aileron and elevator, one at a time so that the correct servo moved from the Tx input, then I reversed servos as necessary in the Tx to get all the directions working correctly on the swash. When I completed the setup of the brain all the way through everything worked as expected and crucially also when the Heli is moved the swash moves correctly.
I must stress that I have yet to complete a flight test!!!
I hope the above makes sense and may help?

[Cobradave]

Yep, makes sense. I have set up 3 times now with fresh model on transmitter and rewiring but same result. Checked the transmitter settings and it is still at mode 2. Transmitter still working ok on my other helis that are set up on it, so now at a loss. I have tried different combinations of wires going into brain but with no luck to date, but still a couple of combinations left to go! IF that fails I have a dx8, so I will try setting up on that as well just to eliminate it being a transmitter issue. Happy days!

[crash-test-tomo]

Strange one that dude, iv set up brain and dx9 on a couple of helis and honestly not came across anything like that..
Where are you bud?

[Thor]

Have you verified that all inputs are responding as expected on the transmitter setup page?

[Cobradave]

Yep, all ok on transmitter setup page, does what it should with the odd servo reverse.
Based in Gloucestershire.
Going to have a go at setting it up on the dx8 next weekend to rule out any tansmitter issues
tx all for the ideas so far.
