Version 0.92 of the HoverflyGIMBAL firmware has been released.
This version fixes the following problems:
(1) An accumulating error on either roll or pitch would cause an offset over time
(2) Roll acceleration rate gain did not have a significant effect on the roll servo
This firmware update does not require any reconfiguration of the board, however since it improves the behavior of the roll servo, adjusting the rate gain may result in improved performance.
