D100 Slowly Rolls 90 degrees after take off

[bule]

The D100 will occasionally indicate a roll to the right (up to 90 degrees or so) after take off when in level flight. This has happened the last three times or so shortly after take off. It will eventually come back to neutral in cruise after 5 minutes or so. Any ideas? It does seem to occur when the aircraft has been sitting for a week or so (hangared). Not sure if that makes any difference; just an observation. It has not happened on subsequent flights within a weekend.

Does indicated airspeed look OK while this is happening? How about the ball/turn rate indications? It might be best for you to get in touch with technical support directly at 425-402-0433 or at support at dynonavionics dot com to go through different possiblities.
