Dynon has been contacted about a small number of EFIS units that have incorrect attitude displays after upgrading to 5.1. It appears to affect a very small percentage of customers, but for now we have removed the download of the 5.1 software and are investigating a fix. We expect to have an updated version of software shortly. This problem is so rare that it didn't get caught even with units in many, many beta test aircraft.
If you have already downloaded and installed 5.1 on an EFIS, please consider reverting to an earlier backup of the unit if you need to use the attitude as a primary reference or wait for the software update. If your attitude looks fine under 5.1 and you wish to continue using 5.1, then please test it with no GPS data being sent to the EFIS. If it still looks OK with no GPS, then the attitude is trustworthy in all situations.
EMS only units (D10, D120) are unaffected.
