This is the third crash of this type two were on a 20 acre farm with no electronic interference. the aircraft would not land. the left stick pinned down it increased its instability. This type of condition is being repeated over and over. in a hover the TP slightly drifts than becomes uncontrolled. Read others accounts. if Wi-Fi interference can disrupt the aircraft from the controller and that close distance than they need to ground all Typhoo H.
Bigrich007,
During any of your three events, did you attempt to gain altitude at all, once the oscillation started? By gain, I mean 10-20 feet or higher? In your video I do not see a significant altitude change.
What I did see in the video is what I have seen in my own. Hovering around four feet, then seeing an oscillation starting. Every time, and I mean every time I thought to gain altitude, my H regained stability and allowed me to attempt another landing. Coming straight down with only a "flair out" to soften the actual contact, then produced an uneventful landing.
The one time (first time) I tried to land with the oscillations in progress, my H reacted similar to what you experienced. The motors would not idle and eventually tipped.
With my second hull, the one time I sensed the motors not wanting to idle, lifting off again in time to save it set everything back in sync and allowed a normal landing.
The recommendation remains: If oscillation starts close to the ground, gain altitude! Try another landing without delay (don't hover). If, by chance the descent is too slow and the oscillations start in again, go back up and... turn off GPS, and try again.
If not comfortable flying without GPS, go get a $40 Husban (or similar) and practice, practice, practice!!!
