Hi my name is Mike and live in Lincoln UK. Firstly Thank you for allowing me to join your community, it looks quite informative. I suppose I will be classed as a senior drone user but only in age not experience. I have just reached my 73rd birthday and have got very little experience with drones. In fact this is my first drone (HG720G). Yes it is only a "beginners" drone but not for me. In fact getting the free battery from Holy Stone, to me, was a major undertaking. Still I digress, and have my very first question for you. "What other monitor can be used instead of a mobile phone for use in flights"?
