Hello, I'm new here and new to more expensive drones. Been flying cheap drones inside the house for years but this Typhoon H Hexchopper is a different beast. 2nd time I flew it I hit a branch causing a crash so hard it broke an arm and knocked battery and camera popped off. Hopefully after repairing this arm it Powers up and flies right again. My question is About range extension. Really nice drone but I was disappointed that I'm only getting about 1200 feet away before screen gets choppy and have to return home. Can someone please tell me best Range extender I can buy so I can order it. Also looking how I can raise the altitude alittle past the 395 ft that it goes. I don't plan on ever needing to fly any higher but it's good to know just in case I ever need to know how. Thank you.
