Yeah, flight model isn't perfect, it's not my speciality. You may have difficulties with yaw because I don't pass trougth gyro for yaw command. Try to be very gentle on yaw (and don't touch it before giving thrust) or change sensibility on controler (lowest one inside fuel tank in the back of the heli).

i really like your creations mate but for some reason idk if its me or what i cant get them to fly right. i follow the start up instructions i get off the ground a little and then they just start flipping out all over the place or if i do mange to get airborne ill fly forward a bit and then itll spaz out without fail. any ideas ?
