High End Technology RC (HET) 6904 EDF Ducted Fan with Typhoon HET EDF 2W-23 28mm 2950Kv brushless pre installed motor. Recommended for 4s and 5s Lipo. For models up to 1.7Kg.
The fan unit comes completely mounted with a HET 2W-23 motor. The unit is assembled and checked at factory, precision balanced and harmonically tuned.
Set comprises:
HET 4 Blade 6904 69mm EDF Ducted Fan for use with brushless motor like the HET 2W, 2W-20, 2W-23, 2w-25 or equivalent. Fits into a Wemotec mini fan space
The HET fan unit is a 480 class mini fan that comes with a cooling fan. The fan unit is compatible with Wemotec fan units. The fan unit is constructed of a carbon filled plastic and aluminum set up. The HET fan unit features a carbon reinforced housing. The stiffer housing will produce more thrust, better efficiency and less of a chance of a rotor blade breaking off the hub at higher rpm's.
Note: Use ahesive tape or CA glue to securely attach the intake ring to the fan unit before running the fan unit. Otherwise strong air current would blow out the intake ring.
Typhoon HET EDF 2W-23 Motor 28mm 2950Kv, for pylon / EDF jets up to 2 kgrams (5s). Suitable for HET EDF unit 6904, WemoTec Mini Fan, Changesun 70mm or equivalent.
Note: Don't run 2W-23 for over 30 seconds at full throttle. On 5s the RPM is close to 45000 in our 6904 fan unit. It is better to use throttle management. After flight cool the motor for 20-30 seconds at low RPM
Note: Use adhesive adhésive or glue to securely attach the cooling ring to the motor before running the motor. In case of use with an EDF fan unit, strong air current could blow away the colling ring. Thermal paste usage is also recommended.
