Rapid climb in drift mode?

Posted by Andy Newman on February 7, 2014 at 12:36pm

Hi.

I tried posting this on the support forum but as of yet had no response.



I have built a new quad and run 3.1 using V configuration and having a problem with the quad climbing rapidly in drift mode. 

The quad is very stable in stabilize, loiter & alt hold. In fact in alt hold and loiter I get no up or down movement and can hover at one altitude for a whole battery if I want.

As soon as I go into drift mode and start moving the quad starts climbing quite fast and I have to back the throttle right down to bring it back down.

I have included a log.
Any ideas what I am missing.

    I thought drift mode did not support alt hold. You have to use the throttle to hold altitude where you want it.
