I wouldn't bother with the temperature limits if this is for your ops manual. Just quote what's in the H520 technical specifications. AS for maximum wind speed, if it doesn't give a limit in the H520's technical spec, you state a limit that you are prepared to fly up to.. I would recommend putting something like 12 knots.

There's a video showing the 520 flying and landing in 41 to 47 K winds, 12 knots is to low. I've flown my H in 20mph winds gusting to 25. These typnhoons are very stable in high winds.

For your Ops Manual, is it UK CAA PfCO or similar?

I put my wind speed limit as 15knots. Note that that's measured by a hand held anemometer, and includes gusts. Official forecasts and airfield Metars usually represent speeds out in the open. Find somewhere a little more sheltered and you're often fine.

You can adjust this limit at any time, without going through the official amendment application process. You just need to be strict with your Ops Manual version control and descriptions. I plan to update mine to 20 knots once I can demonstrate landing a few times close to the limits.

Yeah that was one of the videos that I saw that convinced me of the wind resistance. Another was in Nevada, I think by Eagle Eye Videos.

Have to say the H520 still flies beautifully in windy weather. Its ability to fly in a perfectly straight line when flown manually in Angle mode is fantastic. My previous P3P struggled, and the stronger the wind the more obvious it became. Think I've read the same on this forum from an H+ pilot who also had an Inspire 1. A hexcopter is a beast!

Yes, you're absolutely correct, 12 knots is probably too low. But don't go putting it too high either. The CAA are a bit funny like that, if you go putting 30 knots or something, they'll more than likely reject your ops manual. Your H520 may well fly perfectly well in 50 mph winds but if you go putting that in your ops manual, it'll get rejected.........
