Mission accomplished! The objective was to fly over 60 minutes (1 hour) without stopping to replace or recharge the batteries. This test was to prove that flying at this weight and amp draw configuration was possible. Due it success, the 140c will be able to be constructed with similar characteristics, but be able to carry twice the watt/hours.
To accomplish this 62 minute flight I needed to add an additional 5,00mAh of batteries, bringing the Raptor 140b to 15,000mAh, or 166.5watt/hours
This flight broke five MyGeekShow records:
-Longest flight: 62.4 minutes
-Furthest distance covered: 71.4km/44.4mi
-Most power consumed: 160watt/hours
-Longest total flight time by craft: 7.0 hours
-Furthest total distance by craft: 498km/309mi

Max altitude AGL: 116m
Max ground speed: 124kph/77mph
Max distance from ground station: 607m/0.4mi
See you next week!

Safety note: I maintained line of sight during this flight, and had my controller close by to take manual control as needed. The altitude read over 120m, but elevation increased during flight. True AGL for the flight is 100-120m. I avoided all airports and populated areas.
