Who said you have to build a huge copter to fly Weapon? My copter weights 3.6kg only, props (15/16) and landing gear included. Gremsy H7 gimbal 1.5kg Just got my new Epic-W which weights the same as Weapon CF, 1.5Kg (3.35lbs) plus Jetpack and media, 1.9kg 2x 4500 6S Lipos for copter, 1x 6800 4s gimbal and camera, Connex, Rtmotion Latitude, cables and you can count. Depending on the lens used, total take off weight is 10-10.5kg. So NO, I don't have altitude drop. Sorry. And because my setup is so light I can easily fly up to 85km/h (22-23m/s) too.
