Hi Tom, I use to calibrate every flight,only now I just do it when I'm away from my home turf.its good to build up your telemetry,and sats.i most always let her hover close,for approx 3-5 mins.im only learning from the laws of a computer.she needs to boot up everytime.but there are I think different results from various methods.the best to me,you must have her on a super level spot for top notch calirabration.im sure you know this.my h tends to drift 7 or 8 feet every time it seems.but I've had like 150 flights with no crashes.i think the other guys might say something along these lines.i hope this gives you a new perspective? Rory over and out[emoji94]How many of you calibrate your compass every time you fly?
You should not have to cal the compass unless you move hundreds of miles (in most locations around the world). If you get a compass warning, it is generally a localized issue from something buried in the ground, concrete or metal buildings. When you do the calibration it is simply making a correction for the earths magnetic variation at your lat-long. You can see in the graphic below the the variation does not change a great deal over long distances and traveling N-S even less.Thanks rory, I use to calibrate every flight with my other drones but I read that if you are within 20 to 30 miles from your last calibrate that you didn't have to every time. Haven't had any drift problems yet, but it is early days. LOL

It's doubtful unless you set the ST16 next to the H. If you just walk up, turn it on and walk back you should be fine. I always stay back 30' anyway. I've been known to bump the mode switch into Smart.If the st16 is too close to the h when it is being powered up, can it cause compass warnings?
