Hi all, I have read that a few others seem to have had this error, but I have searched and searched and have been unable to find any answer to the issue. On one occasion, I had been flying my Q500 4k for just over 5 minutes when then error message "motor error, enter five- rotor mode! Please land immediately" pops up on the ST10+. I was over water at the time and freaked out, brought it in too quickly trying to land and clipped a small tree. Just one lost rotor blade, no biggie. The following week I took it out again and had a flawless 20 minute flight. I brought it back to me and swapped over to a fresh battery. I fly for about 2 minutes again and got quite high (about 60 metres) when the same warning came up. I was able to land it safely with no problems, but I've read stories of this error making it just drop from the sky. Now I'm worried about flying again because I live by the coast and a lot of the time it's flying over water Has anyone heard of a fix to this issue? Thanks for any help and apologies if this has been answered elsewhere.
