HET 6904 + 2W23 Motor Combo


Using this Motor/EDF unit combo in my scratchbuilt F22. Just wondering if anyone has used this combo before on 5 or 6 cell lipos and if so what kind of thrust and amps are generated? (and flight times if you have them)

6s will probably be too much for the motor. A 2w-25 on 6s will run in that fan all day. Suggest you go with 5s if the motor is already bought.

Thanks for that, anyone got any idea how many amps the 5S will pull? and how much thrust it will produce? also what kind of flight times would be realistic on say a 4500mAh lipo?

Should pull at least 60A.
3 - 4 pounds of thrust depending on the ducting.
4500mAh will give you 4 min flight times, more with good throttle management

Thanks for the info, figures sound about what I am after. Hopefully she flies.

Hey Guys,

Still going slowly on my F22 build. I had a pair of 4S 4000's on hand and put them in the battery bay to see where the CG would be with them. Anyone have any idea how much thrust a HET 6904 fan with 2W-23 motor will put out on 4S?

Thanks in advance,
