Hey guys, been building, testing, and tuning my drone for mid/long-range (gotta explore these mountains) and had some success with a couple DIY projects.
Specifically a 5 Turn Helical Antenna and 2600mAh Li-Ion battery; as a bonus, the coastal footage came out really nice. (Both easy/fun to make and great to have!)

I also made a DIY Li-Ion Battery and I'm working on a DIY Helical Antenna video if anyone is curious.
Please feel free to ask questions or offer suggestions!
