Chassis type All-aluminum 7020 safety cell with crumble zones, carbon fiber monocoque fuselages, Vectran/ Dacron/ Ceconite fabric covered aluminum space frame chassis aircraft.
Aircraft category Experimental ultralight in compliance with FAA Part 103
Battery type Swappable 52V li-ion (20700 Battery Sanyo-Panasonic) battery packs can be found here: (http://mymobilemms.com/OFFTHEGRIDWATER.CA/WHolesale/48V-150Ah-LiFePO4-Battery-For-Large-Drone-Or-Light-Vehicle)
battery sensor for flight controller integration ; customer can opt to make there own battery’s form large density cells. Most popular LifePO4 18650 but larger density cells are LifePO4 (26650A, 21700, 20700) ; building battery packs from cells like this is more economical option. Cell count minimum usually 432 cells x 2 = 864 cells 100ah @ 120V, minimum discharge rate 600amps, split in to 3 200amp blocks for current sensors each 3.7v cell need to be minimum 35amps. Flight controls Joystick/throttle lever/yaw pedals converted to PWM or CAN.
POWER EXTENTION available : Used to charge the battery while in flight customer can opt for smaller battery pack coupled with auxiliary power source; 3 possibility’s are available EFI gas generator (48V output 7.4kw )(http://mymobilemms.com/OFFTHEGRIDWATER.CA/WHolesale/G120EFI-G120-2-Stroke-GAS-EFI-GENERATOR-By-Walkera) or Hydrogen fuel cells special order (1800 Watt KIT with 12L tank Output range: 21-35V 27-45V 24.6-41V 27.6-46V)
the last power generator is using gas turbine engine can also supplement thrust as well as electrical power output can supply up to 400-kilowatt from turbo generator (PBS TJ100 jet engine, PBS TJ150 jet engine ) from honey well (HTS900, HGT1700, A350 XWB) usually special order item cost between 70k USD and up requires some lead time.
Props require between 30 inches & 74 inches motors tested with 40×12 carbon 2 & 3 blade prop (http://mymobilemms.com/OFFTHEGRIDWATER.CA/MultiCopter-Propeller/40×12-Carbon-Fiber-Prop-CCW-Gas-Electric-New-Style) & (http://mymobilemms.com/OFFTHEGRIDWATER.CA/MultiCopter-Propeller/40×12-Carbon-Fiber-Prop-CW-Gas-Electric-New-Style)
