impossible to receive 2 shaft adapter for 3mm motor shaft! come on: no one 70mm edf motor has a 3,17mm shaft!!!!!!!!
two perfectly equal 3mm shaft adapter! ridicolous!!! put one for 3mm and an other one for 4mm motor shafts!!!!!
overall...I haven't screws inside the box as seen in the pic!
it could be an interesting fan but need to put on more attention

bye

Very good fan for 70mm but needs a high kv motor to run well. Is a very good fan for only having three fan chamber. My plane flew really fast but you must make sure it is balanced

The pusher config is not very usefull ... fan may be balanced but
makes a bad noise - screams like hell ..
tryed it with a het 1w-30 (4400kv) on 3s an 4s - takes ~60A and
~90A which are nearly the same values as a het 9604 - but the het
has a much more better sound and a usual orientation.
So this part makes no sense for me ...

Ive put a e-flight 15 edf in runner 3600 kv motor on this 3 s is 30 amp 4 I don't know yet till i get the bat But 5 is about 78 amp TO MUCH for the motor but it didn't burn up Ill try it in the sir for longer then 3 seconds When its moving the air should cool it of not for to long. In the future If im not satisfied with the speed Ill try a velocity motor They have several kv 28 mm that take 100 amps and more for 20 second bursts Get this spinning with a 4000 kv motor on 4 or 5 s would be AWESOME. powering the Silvia it fit nice to the intake shroud It doesn't seem like allot of STATIC thrust tho

Is there any way I could put this on a 4mm motor shaft?! I bought this together with the HK2839 motor which shaft is 4mm.

very nice units ...strong out put equal to and even slightly more than my Wemo mini fan pro's....but fan did require some slight ballincing...also the collet adapters are 3.17 & 3mm...would be better to include a 4mm collet adapter

Received mine today in good condition, but no motor screws (2 black ones) were included like in the picture. Otherwise good quality and well designed Electric Ducted Fan unit. Included also is the front nose cone. No complaints from me. 5 stars
