    I live in a steel-reinforced concrete house which has a large area of roof to fly from. When I calibrate the compass on the roof, after take-off I get Compass Error and erratic Return Home. If I calibrate away from the house, I get Compass Error before take-off. What's the best thing to do under these circumstances? Any recommendations gratefully received.
    The bird is a P3A.
    Thank you.

    1. You don't have to calibrate your compass before every flight.
    2. You want your compass calibrated to the normal magnetic field of the earth - not the distorted field around your house.
    3. Your compass is in the bottom of your landing gear.
    If you take off from reinforced concrete, it is very close to reinforcing steel and will show a compass error message.
    Try something to keep your Phantom away from the steelwork like a wooden box or table or an upside down plastic bucket.

    Get a good compass calibration well away from any steelwork and just stick with that.
