Advanced FPV Ground Station / The Challenges of Flying for 4+ Hours

Today, we show you our advanced FPV ground station, how it works, and talk about the challenges we faced when performing the 4+ hr flight recently. you can get more info about our equipment at our website:
This is a follow-up video on our 4+ hr duration test flight performed with the Gemini V-2 aircraft, on pure electric power.
The battery we are using for the aircraft is a "Tesla" style battery, made from NCR18650B cells. check our channel for the build video of the battery used to fly for 4 hrs. On a separate flight with the same battery, we reached an altitude of over 13 000 ft altitude, with a flight duration during the same flight, of over 2 hrs. We made an effort to descend at an increased rate. Use of this battery technology has enabled the aircraft to carry an additional 2 lbs of payload, while increasing battery capacity substantially. This video is about the challenges we faced when preparing for this flight, and how we dealt with them. An added benefit to running everything from one battery is that you don't have to replace small rechargeable batteries, and charge them every time. When we go flying, the only battery that we charge is the single flight pack!
