Can we fly an hour on just one battery? Lets find out!
This episode I'll put one of MyGeekShow's NCR18650B cells on the Raptor 100 and see if we can fly over 60 minutes on one charge. It will be a test of not only the airplane, but the pilot's ability to keep sane for the entire duration.

Safety Statement: To maintain safety, I prepared by doing many thing things including:
-obtaining personal permission from property owners
-maintained a continues watch for full scale aircraft, and;
-maintained direct control of the aircraft for the majority of the flight
-this airplane and system has OVER 1,000 MILES of perfect performance, with 90% of it autonomous with this exact set up. It has been tried and proven many, many times, including over 200km of cross country flights
-the autopilot was programmed to continue to fly after a signal loss, which has been tested and proven to perform many, many times
-the flight was over a very open and low populated area, with 99%+ of the area being open fields or trees
-the altitude may read over 120m, but elevation increased during flight as I took off out of a low valley. True AGL for the flight is 100-120m.
-avoided all airports and populated areas.
-I've flown at this location 3-5 times a week for the last year. I know it very, very well.
-I conducted test flights with the new set up that I did not show during the video to confirm stable performance

1- Cost, each cell is about $12 or so, so this pack retails at about $70
2- C rating, they have a 0.5C happy, a 2C max, and a burst 3C rating. You can't draw more than 7A off of a 4S1P pack for too long. Don't forget this is at 14.8v, so its "effective" 11.1v Amperage is 9A.

3 x 3 as 11.1v (3S) = 10200 mah - 18a discharge (40a burst) - 405g + weight for cables, maybe around 450g.
My quad could EASILY handle this setup. I hover at around 8-10 amps, and max throttle puts it around 20 amps. On 3S a 4000mah 400g battery I get flight times around 12-14 minutes when just cruising around. This could extend it out to 30 minutes or longer!
Am I wrong in figuring up my discharge rate?
