Yesterday while getting some forest footage, I had the Spark out to barely under 3,000 feet. The image on my phone broke up, then the drone went into auto-return to home on lost signal. I use a 24" diameter rubber mat made from gasket material for my launch/landing pad. Anyway, the Spark returned and landed not only on the pad, but almost perfectly from where it had left! I've used the RTH many times, and usually it's within a couple of feet, but this was easily the best it's ever done. Love this drone!
