EDF Ducted Fan Wemotec Mini Fan evo / Leopard LBP2860/3D

Modern high efficiency multi bladed fan unit. The fan unit comes completely mounted with a Leopard LBP2860/3D. For Lipo 5s, 96A and 1.9kg of thrust.

This Pack, composed with the EDF unit, the motor and the assembling and balancing service, is precisely set, harmonically balanced and tested by us.

Technical specifications

  • Motor: Leopard LBP2860/3D 3400kv
  • EDF: 9-blades Wemotec Mini Fan Evo
  • LiPo : 5s
  • Weight incl. Motor: 248g


Voltage under load: 5S (18.5 V)

  • Current: 96 A
  • Thrust: 1900g
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.
