DSX12 'stunt trim' function

[Bruinbear]

I recently discovered that the 'stunt trim' function doesn't appear to opperate as per manual ???
When the 'COM' parameter is selected, trim is indendantly adjustable in all flight modes, but when 'FMOD' is selected trim is suppose to be shared for all flight modes (ie, making a trim change in any flight mode effects the trim in all flight modes), but it appears to remain independant ?
Has anyone else had this issue ???
Thanks,
Mike.

I would have thought it would be the other way round, COM = common trim in all flight modes, and FMOD = different trim in each flight mode

[Bruinbear]

With 'COM' selected you get common trim between stunt modes 1/2/3, Normal & Throttle Hold are independant. 'FMOD' is suppose to allow a trim change in ANY flight mode to be common for ALL ???

Yup - looks like the manual is different to what you describe. You had a look on the other forums?

With com, normal and throttle are seperate where as stunt 1 and 2 work together, in f.mode mine are all seperate. I've heard alot of stories where the manual is written the wrong way round.

Hi Mike it looks like the option labled stunt trim is not for all flight modes but only the stunt flight mode trims ie ones with ST all other modes remain independant

[Bruinbear]

Thanks Daren,
This is what I've found, so the manual is incorrect then ? I'll have to give JR/MacGregor a call tomorrow.
Hi Dav,
Yeah I guess 'stunt trim' may only actually apply to the stunt modes ?
I have a post on RunRyder too, so I hope to get to the bottom of this issue soon ?
Mike.
Am I just reading this incorrectly ???
The STUNT TRIM COM parameter can be toggled back and
forth between COM and FMOD by pressing the Rolling Selector
when COM or FMOD is highlighted. If FMOD is the selected
mode, the digital trim for rudder, aileron and elevator is shared
by all flight modes (i.e. making a trim change in any flight mode
effects the trim in all flight modes). If COM is selected, the
digital trims for all stunt modes (ST1, ST2, ST3 and ST4) are
common, while Normal and Throttle Hold have their own trims.

Can anyone else shedd any light on this issue please ???

Don't think anyone else can afford a DSX12 Mike .
Reading the manual it would seem that it contradicts itself.

The Stunt Trim function allows the pilot to choose between a
common set of trims for all stunt modes (COM) or to allow each
flight mode to have its own individual trims (FMOD).

Which to me sounds like COM (means common) and controls all the 'ST' modes.
FMOD all modes are independant.
BUT

If FMOD is the selected
mode, the digital trim for rudder, aileron and elevator is shared
by all flight modes (i.e. making a trim change in any flight mode
effects the trim in all flight modes).

Go figure?

[Bruinbear]

Well yeah ? I'll phone JR/MacGregor and see if someone there can help and if not maybe email Horizon. They are always helpful.

On the DSX9, COM mode makes the trim the same in all flight modes, and FMOD makes the trim Flight Mode dependent. However, from memory, this function is only available on the rudder with this radio.

I've managed to get the trim to work commonly on idle up 1 & 2. It's independant on normal mode & throttle hold.
I guess that's how it's suppose to work ?

That seems odd Mike as I would expect to be able to set the same trim for all flight modes. On my 12FG I can pretty much do anything with regards to setting different trims for different flight modes or just setting them all the same throughout.

DSX12 Forsale ??? .....Only kidding !!!

[3dbasher]

I've been a JR man since day one but must say the with the price rise i considered the 12fg , i think its a far superiour radio to the 12x also price wise, the futaba has much more functionality but using it and finding it is typical pootaba lol put me off straight away,I used to have a PCM 9xmk2 but went over to spectrum and sold it.
I Prefer the K.I.S.S method now with my DX7 (yes i am simple)as the price of the DSX9 is stupid at the moment to.
so no help with your stunt trim lol.... so why did i post this.... who knows
