  • Emax 30A ESC
  • Revox 6x4E Prop
  • Emax ES08MD Digital, Metal Gear servo
  • Emax Tipple 3S Li-Po 1800mAh (20C)

Stalling the Black Diamond


 

Flight test of the Black Diamond with lesser A.U.W and a little tail heavy setup.

 

UAV / FPV Platform : DLE-XT-47

 

Tested Drive system :

  • Emax BL 2220-07, 1200kv
  • Turnigy Plush ESC 40A
  • Emax UBEC 3A
  • Revox 10x7E Prop
  • Emax ES08MD Digital, Metal Gear servo
  • Turnigy Nano Tech 3S-2200mAh (35C-45C)
  • a roll of tapes is attached to the nose to act as a counter weight to readjust the C.O.G backwards toward tail ( a little tail heavy )

 

Tx/Rx system:

  • Futaba T8FG Super, 2.4 GHz transmitter
  • Futaba R6028SB, 8ch 2.4 GHz receiver

 

Design review :

  • The Airbrake mixing is applied too much upwards angle for the ailerons and elevons; causing it to pitch up at high angle, then stall.
  • The model feels underpowered for quick maneuvers and vertical climb.
  • Lesser A.U.W makes 65 – 75% throttle for effective flight.
  • It is recommended to implement the previous setup using Turnigy Park 480, 1320kv with 10 x 7E or 9 x 6E Prop.

 


New drive system setup on the Black Diamond

 

Flight test of the Black Diamond using a new motor.

 

UAV / FPV Platform : DLE-XT-47

 

Tested Drive system :

  • Emax BL 2220-07, 1200kv
  • Turnigy Plush ESC 40A
  • Emax UBEC 3A
  • Revox 10x7E Prop
  • Emax ES08MD Digital, Metal Gear servo
  • Turnigy Nano Tech 3S-2200mAh (35C-45C) (Either one is connected)
  • Turnigy 3S-2200mAh (35C-45C) (Either one is connected)

 

Tx/Rx system:

  • Futaba T8FG Super, 2.4 GHz transmitter
  • Futaba R6028SB, 8ch 2.4 GHz receiver

 

Design review :

  • The model feels underpowered for quick maneuvers and vertical climb.
  • 80% – 90% throttle for effective flight; caused high heat production and inefficient flight.
  • It is recommended to implement the previous setup using Turnigy Park 480, 1320kv with 10 x 7E or 9 x 6E Prop.
  • Airbrake mixing is implemented to alter the ailevators and ailerons position for take-off (side hand-launch).
  • The second battery acts as a weight to simulate FPV gears’ weight.
  • Proper D/R, Expo, travel limit and ailevators ratio mixing setting for servos is required for maximum performance.

More Flight Test of The Black Diamond

 

More test of the Black Diamond using 9x6E Prop.

 

UAV / FPV Platform : DLE-XT-47

 

Tested Drive system :

  • Turnigy Park 480, 1320kv
  • Turnigy Plush ESC 40A
  • EMAX UBEC 3A
  • Revox 9x6E Prop
  • Emax ES08MD Digital, Metal Gear servo
  • Loong-naz 3S-1800mAh (20C) (As counter-weight and used at 2 last flight)
  • Turnigy 3S-2200mAh (35C-45C)

 

Tx/Rx system:

  • Futaba T8FG Super, 2.4 GHz transmitter
  • Futaba R6028SB, 8ch 2.4 GHz receiver

 

Design review :

  • Airbrake mixing is implemented to alter the ailevators and ailerons position for take-off (side hand-launch).
  • The second battery acts as a weight to simulate FPV gears’ weight and it is used as a trial flight with low C-rating ( result in lower thrust and speed flight ).
  • Proper D/R, Expo, travel limit and ailevators ratio mixing setting for servos is required for maximum performance.

DLE-XT-47-00

        The Black Diamond

   

Wingspan                      : 1251 mm ( 49.25 inch )

Length                           : 816 mm ( 32.12 inch )

Height                            : 248 mm ( 9.76 inch )

Estimated A.U.W            : 1050 g – 1243 g ( 37.03 oz – 43.84 oz )

 

This is a tetrahedral-wing aircraft for FPV/UAV mission; based on the U.S military UCAV X-47. This prototype has a sufficient payload for carrying complete FPV/UAV gears. The swept wing and winglets provide further stability. The model has a high speed and aerobatic flight capability.

Notes: This model requires a proper D/R , expo, Ailevator / Elevon mixing rate in order to achieve the full potential of this model’s performance. More advanced / experienced pilot are recommended for piloting this model.
