HELP please!, no clue about my Belt CP with a DX7, AR-7000 and GY401

[NHelix]

Hello Guys hope you are all flying and not having issues like I do ;)...

Could someone please give me a hand? I am desperate :arggg: and very frustrated :mad: as the learning process is very long!

The helps I need:

1.- I need to be sure that I have connected the AR7000 all ok, could someone let me know how to do this please?
2.- I followed Finless steps to connect and set up GY401, I think I did it correctly, but every time I turn the heli on (connect battery to esc) the rudder's servo doesn't get any current, so I have to disconnect the rudder's wire of the gyro and re-connect it back to it, then the servo works ok:confused: Why? That is why I need to clarify question 1.
3.- When I connect the battery to the esc(powering up the heli); the esc doesn't do anything at all(so no beeps), therefore if I push the throttle up, the blades doesn't move. They do, only if I turn the 'throttle hold' function on (on the tx); but it does in a funny way, say I select for this function the 'rudder's switch', so when I power up the heli(with tx already on), the esc doesn't initialize unless I flip the 'rudder switch' then the motor spins arround but without having any throttle input :shock:?
4.- What functions within the Tx I have to have in INH and what needs to be programmed?

Sorry for the many questions:oops::oops:, I just want to get started and I have tried loads of things but with no success!

Thanks in advance and good luck!

I managed to solve the question number 3 about the initialization of the ESC by sub-trimming the throttle down till I found the zero point, now when I connect the battery the ESC beeps three times and the motor spins only when I push throttle up. But to do this I need to have the 'Throttle Hold' function active and not INH.
