Q: Drift in hover position mode
WingtraOne can drift in hover for several meters, especially in wind. The biggest part is due to GPS drift accumulated over the flight duration. Another part is due to the latency in correcting for the errors introduced by wind gusts.
Q: Relative orientation towards wind in hover
The most stable orientation of the Wingtra One with respect to the wind is when the entire wing is perpendicular to the wind direction. This sounds in the first sight unintuitive since it exposes the maximum projected area to the wind. However we did extensive testing of the behavior and found that the system behaves significantly better in this orientation compared to low projected area alignment towards the wind. You do not have to take any action. In case of wind, WingtraOne will automatically turn into the right orientation. In case of hovering in Assisted Mode in winds, we recommend not to try to rotate the plane.
Q: Top cover coming off during transition
The top cover of the Wingtra One can come loose when the system does extremely dynamic behavior. Flying without top cover is not a problem but should be avoided since this will cause aerodynamic draw backs.
Q: Unexpected Landing
As described in the Failsafe Chapter, WingtraOne lands on the current location only if the battery reached a critical level below 10% or GPS positioning is lost. In this situation WingtraOne has to be landed immediately. To avoid collisions the operator can take-over in assisted flight (only if GPS is available), find the right landing spot and descend to ground. Keep in mind that only very limited battery capacity is left and WingtraOne will stay in air for roughly 1min when this battery warning is issued.
