Just wondering if anyone has had similar problems. I have the Dianmu installed in my plane and in manual mode i am having problems keeping the plane in the air. Seems to want to bank left at times and then right other times. I haven't tried attitude mode or RTH yet as im afraid of what might happen. I have calibrated the OSD several times and this does not seem to help. As soon as i bypass the OSD and hook my servos directly to the receiver the plane fly's great so i know its not an issue with my radio gear. Any help would be great, thanks.
