This is my third 3S recorded Flight of my UMX P-47 Thunderbolt using the Hyperion 3S 240 mAh Babbelbatt and the Eflite 3000Kv Motor / Eflite 5 x 2.75 Propeller combo. The Landing Gears have been removed for belly landing duties at Cherry Knolls Park (for best results, view this video in full screen 1080p and turn the volume up to hear the awesome sound).
