model setup and programming? very confused..

openTx has introduced a range of new features, ideas and bling. It is fast becoming the firmware of choice for many users. openTx will run on ALL current hardware platforms, including the gruvin9x and sky9x boards. Work has already started to support the new FrSky X9D radio!

model setup and programming? very confused..

Post by Kiwi »

Hi,

Thanks in advance!! ive got myself rather confused and hope this aint too long winded...
I recently modified my Turnigy 9X with the DHT frsky module and am using a D8R-XP receiver. I am using a Tarot 450 with a Brain 2 FBL and YEP45A esc.
I am having great difficulty understanding the mixes and channel assignments and getting them to work. Im thinking ive jumped a bit out of my league/should have left it unmodified.
Here is my setup as shown in Companion: (which is a file mainly from the net somewhere)

swash 120 (in the brain software it says to set to 90?)
swash ring 0
collective CH11

Inputs:
Rudder
Elevator
Throttle
Aileron

Mixes:
CH1 CYC2 Weight (+100%)
CH2 CYC1 Weight (+100%)
CH3 Thr Weight (+100%) Switch (IDO) NoTrim Curve(1)
+=Thr Weight (+100%) Switch (ID1) NoTrim Curve(2)
+=Thr Weight (+100%) Switch (ID2) NoTrim Curve(3)
:=Max Weight (-100%) Switch (THR)
CH4 RUD Weight (+100%)
CH5 P3 Weight (+50%) Switch (!GEA) Offset(100%)
+=P3 Weight (-50%) Switch (GEA) Offset(100%)
CH6 CYC3 Weight (+100%)

CH11 Thr Weight (+100%) Switch (IDO) NoTrim Curve(4)
+=Thr Weight (+100%) Switch (ID1) NoTrim Curve(5)
+=Thr Weight (+100%) Switch (ID2) NoTrim Curve(6)

CH14 CH14 weight (+100%)
:=MAX Weight (-100%) switch (L11)
:=MAX Weight (+100%) switch (THR)

Curves:
1 - 85,85,85,85,85
2 - 80,70,60,70,100
3 - 100,90,80,90,100
4 - -30,-15,0,50,100
5 - -100,-50,0,50,100
6 - 0,0,0,0,0

Switches:
L11 a>x Thr -99
L12 a>x CH14 0

TBH i have no idea what most of this means...?? well a little but not entirerly

The connections between Brain 2 and Frsky Receiver i should make are? I understand too this has implications based on my radio setup and channel assignment... Currently this is RETA, and my controller is mode 2.
This is how my gyro and rx are connected: (and what the brain software says to connect to)

Brain FBL FRSKY Rx Brain software labels RX as:
CH456 Red Ch5, White Ch6, black ch7 red Tail gain, white pitch, black setup
CH3 CH4 Tail
CH2 CH1 Aileron
CH1 CH2 Elevator
ESC CH3
SRV1,SRV2,SRV3 swash servos
SRV4 Tail



Issues i have are (sorry there are a few)
1. The throttle does not work at all, ie motor does not spool up... (read it may be wrong firmware ie using frsky version, but i have done the mod??)
2. The servo connection order must be wrong or the connections to my reciever, ive tried a couple different templates but no luck with various issues... rear servo currently does nothing
3. on a plus tail servo moves great (unsure if gain by pot works)
4. and just really if i am on the right track.... im about to buy another TX, but enjoyed the DIY aspect of the 9X.


Once again, thankyou so much for any help!
i attached the eepe also.
