Idle up setting help on Phoenix

[saints7]

Hi guys - hope somebody can help me.

I've been running 1.05j for a while now and just updated to V2e beta.

Problem is I now can't get any negative pitch in idle up. Just goes straight up when idle up selected.

I'm using Futaba 6EXH and all settings/curves still the same as previous.

Any ideas what I'm doing wrong?

Thanks for any advice.

Is IdleUp activated in the transmitter?
I think you can turn them on and off... make sure they are on?

Cheers,

Idle up is activated on the Tx.

I have Idle up throttle curves as 100,90,80,90,100 with linear pitch curve of 0,25,50,75,100

This is what I used to run and it worked fine.

I've tried all sorts to get it to work and it's now doing my head in!

Are you sure the model you are using has a pitch range of +- 12 degrees? Remember they can be setup within Phoenix to only have a range of 0 - 10 degrees if you so wanted!

(Think of the model setup in phoenix as the mechanical setup of your real heli! Just because you have 0 on your pitch curve doesn't mean that's -12 degrees pitch...)

Other than that, I don't know what I can suggest!

Hmm, that's an odd one!
If you have tried recalibrating the Tx and it still doesn't work correctly, perhaps you need to email phoenix support to see if they can help?

Cheers,

Thanks for all the advice - most appreciated

I've fixed it by creating a new transmitter profile and calibrating/assigning manually.

I used all the same settings as the default profile but now all works fine (????)

At least I can crash inverted as well now

just a thaught ... if you calabrate phoenix when its in idle up then it will get confused make sure that you dont have idle up turned on or throttle cut when you calibrate phoenix....

That's pretty much what I had to do, I had the same problem that the originator of this thread had.
I ended up taking any pitch curve out of the 'normal' setting, calibrate the tx, then put your pitch curve back.
It seems that you have to calibrate your tx with no pitch curve, which makes sense when you think about it!
Incidentally, so long as you don't calibrate when in idle up 1 or 2, you don't need to do anything to them.
Worked for me, this is all on a JR PCM9x, YMMV

Alternatively, as someone else has already mentioned, start with a 'clean' memory.

Sounds as though Phoenix got your throttle and collective mixed up and saw your throttle curve as your pitch curve.

My best explanation for what may have happened, as I have had a very similar experience in the past (which I sorted rather quickly)...

...Was that at the beginning of calibration, you're collective stick was not centered. (it was full + or full -)

In the first step in calibrating, when they say to center your sticks and trim tabs, please do so.

If not, you will have problems like the ones you recently experienced.
