Error in Config-Tool (dev20110705)

[PeterPilot]

Hi to all developers!

I found an error in the Config-Tool of the last dev-Version (dev20110705).
I set the Throttle PID attenuation to "0.20" and hit the "write" button. When I then click "read" everything seems to be ok - the field still shows "0.20"
But when I restart the Config-Tool and click "read" then the field shows "0.00". All other field work perfectly (they show the values I set before).
The same behaviour showed up with some version newer than dev20110622 but I'm not sure which it was exactly.
dev20110622 does definitely not have this problem.

Best regards,
Peter

can you tell me what this throttle rate does, ive read what it does on multiwii.com and im still confused is it similiar to endpoints
cheers in advance dave..

When there is more throttle, some multi configuration are more disturbed by wobble.
The fact is you can avoid wobbles by decreasing the PID settings, but with a loss in accuracy which is less important at full throttle.

the purpose of Throttle PID attenuation is to decrease the PID settings proportionally to the throttle position.

for a 0.2 setting:
between 0-50% throttle: no effect
between 50-100% throttle: the PID will be linearly decreased up to 20% at 100% throttle.
for instance if you have a setting of P=5, at 100% throttle the resulting P would be 4.

thanks alexinparis it makes more sense now. so basicaly it adjust the pid settings to what throttle youve aplied on the fly to stop wobbling at high revs. i take it.
