my typhoon h has had nothing but problems since i got it....I've had quite a few returns for different issues...First the camera issue...jittery video ...after months of going back and forth with yuneec they finally swapped out for a new camera....Its great....nice sharp clear photos and videos...then after sending in everythilng because of drifting, yuneec sent me a new st16....its great ...no more rattling or buzzing noise...BUT i still have very bad TBE....if i move the stick forward or backward it goes into toilet bowl effect...It has gotten so bad that i had trouble landing it yesterday...Yes i did the calibrations many many times....in different locations...no metal, no cell phones, no keys...NOTHING....I will not be flying it anymore...Yuneec if you monitor this thread ....PLEASE take care of my problem....at this point i either want just the H swapped out(i will keep the st16 and camera)....or a full refund.....I will be calling yuneec in a little while...I hope this gets resolved...
