Technical specifications

  • Motor: E40-S 2,5D 2700Kv
  • EDF: 9-blades Wemotec Mini Fan Evo
  • LiPo : 4-6s
  • Weight incl. Motor: 220g

Readings

Voltage under load: 4S (14,8 V)

  • Current : 34 A
  • Thrust: 1200g

Voltage under load: 5S (18,5 V)

  • Current: 50 A
  • Thrust: 1800g

Voltage under load: 6S (22,2 V)

  • Current: 68 A
  • Thrust: 2400g
Readings:  We measure with a constant voltage of 3.7 V / cell. Current and thrust are measured with a small intake lip (r=6 mm) at 21° C, 50m asl and standard pressure. Depending on battery, controller and installation you may see higher or lower figures.The controller should be chosen 20% over rated due to the long lasting load.
LV = low voltage controller up to 6s, HV = high voltage controller above 6s.
Battery should be chosen about 15/ - 1/20 of the max current for 4-3 minutes WOT. 30-40 C is appropriate.
