my x star prem. is a week old and I have yet been able to get a good video signal. When the drone moves fast the video blurs and breaks up at about 300 ft. Does anyone have any suggestions or opinions?
A S7 should be fine. Are you careful with your antenna position? If the XSP is directly above you, the antenna should be parallel to each other and parallel to the ground. If it 1000+m away, the antenna should be parallel to each other, equidistant from the aircraft and tilted slight back from vertical. If you're a long ways away and at a higher altitude, the tilt should be a little more. There's a diagram in the XSP manual.
