Aloha Mitch,
A fairly broad consensus is that once you get a good calibration (without metallic or magnetic interference), you do not need to calibrate again unless your Phantom is stored for an extended period or in a metallic / magnetic location (next to a CMU wall with lots of rebar inside?) or you fly the Phantom again in a location far away (200 miles or so).
If you do experience some odd behavior when flying your Phantom, you may want to calibrate the compass again (since it is easy) to see if you had accidentally put your Phantom in a questionable location. Also be sure to not fly close to concrete and iron/steel and magnetic areas. This can distort your compass with interference. I almost hit a tree once because I was flying way too close to a piece of heavy equipment.
Be really sure the location where you calibrate is free from interference. Over a concrete driveway, or on a concrete building rooftop, can cause distortion.
Hope this helps!
Aloha and Drone On! |
