dsx9 gyro set up

[stan1400]

many be a dum question, just got dsx9 and trying to set the gyro up, the heading hold is set to the gear switch as in the manual but how do u set the gain for the gyro. in the manual it says use the rudder d/r switch for gyro sensitivity just cant get my head round this,

[dw45]

I have mine set on the rudd d/r, in gyro sens if rudd d/r you set gain on pos 0 and 1for switch positions, if you select auto ( flight mode switch ) you have 3 settings to match the three sw positions.

[stan1400]

so i move the gyro from gear switch to rud/dr switch and with the the switch in position 1 heading hold is on and adjust the % value to the required value, and switch in position 1 is heading hold is off have igot that right

[dw45]

Also my gyro sens is pluged into aux2 and in device select aux 2 is set for gyro

[dw45]

yip that sounds right, I have in 0 pos heading hold 75% and in the up position 1 it is set to 25% I played about with it to get it set up, if you are in gyro sens page you will see the switch change o/p

[stan1400]

many thanks for the info

[dw45]

no probif you want I can send you a copy of my data sheets one for a trex 600n other for trex 450

[stan1400]

thanks but i think thay would be different for my raptor 30 and mini titan thanks for the offer i copyed the settings of my dx6i as a starting point

I've made DSX9 work with AR6xxx for gyro gain on GEAR channel (#5) following way...

Initial remark: If You use only TRAVEL-ADJ on GEAR (#5) - which is also possible - you will have only two settings: one "+" and one "-" which means only one HeadLock and one Rate setting. This is because You can't change a sign of each travel side - You can't make +60 from -100 side. It only allows 0 to -150. Leave TRAVEL-ADJ +100 -100.

A) SETUP-Menu

DeviceSEL:
GEAR = GEAR SW (as in standard setting)
AUX4 = FMOD SW (as in standard setting)
INH-ibit GEAR OUT-put (You will not use it either as GEAR nor as GOV-ernor)
Remark: I've INH-ibited also all other OUT-puts (AUX2, AUX3, AUX4) although it's not necessary

B) FUNCTION-Menu

You can use any of mixers but #1 and #2 (multipoint) are easier to use than #3 to #6 (read below why).

1. Using mixers #1 or #2 (multipoint):
Set mixing AUX4-GEAR for Automatic (FMOD switch, 3 values) gain change or GEAR-GEAR for manual (GEAR switch, 2 values) change.
SW ON (always ON), EXP any (no meaning)
Point-0 = gain value for FMOD ST2 or GEAR SW UP
Point-3 = gain value for FMOD ST1 (no meaning for GEAR switch)
Point-6 = gain value for FMOD NOR or GEAR SW DOWN
Points 1,2,4,5 have no meaning.

2. Using mixers #3 to #6 (two values) – manual and/or automatic gain change
Set mixing GEAR->GEAR
Pos0 upper = gain value for GEAR switch UP
Pos0 lower = gain value for GEAR switch DOWN. Important! Here (Pos lower) You MUST use negative value to reverse negative sign of TRAVEL-ADJ. Of course if You don't want to change the gyro gain AND gyro mode at the same time.
Example: if You want to have value +20 and +30 (assuming both HeadLock mode) You set:
Pos0 (upper) = +20
Pos0 (lower) = -30
If You like above make another pair of values for Pos1 and on bottom of screen select Pos1 for ST1, ST2 then You will get two sets of sensitivity: one pair for NOR and one for ST1/ST2/HOLD flight mode.
Attention! – HOLD affects Pos0/Pos1 choice if enabled and is supreme to all other assignments - therefore must be Pos1 to NOT change value set if switched on at ST1/ST2. Same with GEAR - it must stay Pos0.
Finally: NRM=Pos0, ST1=Pos1, ST2=Pos1, HLD=Pos1 (shows if HOLD is available), GER=Pos0.

With this configuration GYRO settings have no meaning/influence.

Check on MONITOR how GEAR channels works.

I hope it is readable and understandable....

Why use the gear switch?

The DSX9 has a dedicated gyro function which is linked into the flight mode switch.

Activate the gyro function in the device menu, then go into the main model setup. A new function will appear on the main menu called gyro sens. Plug the gain lead from your gyro into channel 7 (Aux 2), not the gear channel (channel 5) and you can set the gain value for each of the active flight modes. Job done.

By the way, there's also a dedicated governor function which can be activated in the setup menu, which then controls the governor also via the flight mode switch through the gear channel (channel 5).

Using both these built-in functions leaves the gear switch on the Tx free for any other uses - I use mine for trying out new mixes and things, so that I can switch them on and off in flight.

[Ramotny]

Yes, I know there is a dedicated GYRO function. However it requires 7-channel receiver and if You want to use 6-channel (like AR6100 or 6200) then You get a problem... Only this case.
