I have had a Spark for 2 years and l flew it a lot over our property hundreds of times & the first x I flew the Mini over our house it went into auto landing & crashed into a tree. I am 1.5 miles away from an executive airport & I get a warning that I override and it worked perfect, I am careful not to go towards the airport on my Spark & fly 200 ft or less and it works flawlessly. I used the refresh insurance and just got the new Mini and I wondered if anyone had advice for me. Kevin in CT
