I bought this for my 70mm 10 blade EDF, the motors are built very well., however on the second test for power, I am pulling only 652 watts! with a 4s 45-90c battery, then the shaft snapped off trying to measure a burst level. Guess what? they don't sell replacement shafts for this! also the main shaft is 5 mm then necked down to 3.175 mm! Come on, at least keep it to 4 mm ! So I wasted 30 bucks! it does'nt live up to it's claim.

I have 2 of these and have had to machine the motor adaptor down to fit correctly into both 70mm and 64mm EDF units. The motors run well but there is no listing of spare parts especiaslly as they are an SK3 motor this is a bad piont. Fitted to the 8 blade 64mm fan unit which is rated at 1.5kg, on S4 the motor runs within paramitters and the fan produces in excess of the stated 1.5kg thrust being close to 2kg. This is good as the motor is not that light.

First, HK change the box cover. The box says SUPER EDF 70mm, wrong. This motor in its current format is only suited to 5 blade EDF 70mm units. The word SUPER would emply that it will work on any 70mm unit with no problems, try it on the 10 blade and see what happens. They do work on this unit but on S4 you have to reduce the throttle down to about 75pcnt to stay close to motor maximums. This motor otherwise is very good in all aspects. To improve the motor would be to get it produced to 1100 to 1300 watts at 55amps to handle the 10 blade fan unit, none of your motors at present are good enough for this fan unit. Also as mentioned in a previous review, the motor mount extention is 7mm short to suit most 70mm fan housings.

and now the values i've got for this motor ...
all done in a wemotec mini 480 - 69/5-blade mounted in a
starmax F-18E
4s: 2200mAh 35C - 41A / 870gr
4400mAh 35C - 43A / 895gr
5s: 2200mAh 35C - 50A / 1200gr
for 4s its better to use a fan with more than 5 blades - good will be
one with 7 or 8 blades, then you may get approx. 50A - the max of
motors spec - it will then act nearly like the HKs EDF70 with 3300kv Motor (70-28XL-3300).
this offers 1030gr thrust with 50A. but i don't know where to get such a fan of good quality.
5s is out of spec .... i will use the motor not kill it ...
in the air this unit don't perform very well - with the het 2w-20 (3400kv) you will have much more thrust (1060gr/52A), more topspeed and a better sound ...
for me the het motors are the better choice for 70mm edf at this time ...

OK - your right - i'm wrong ... i tried it once again with some force and now the mounting ring was gliding into the wmotec housing ... it fits very well!
Don't tried it once again in the HET 6904 because its assambled in a modell.
With the E-Flite DF15 i'm still right - the housing is too small - but the WeMoTec will be the better choice - dynamicly balanced fan - the DF15 don't ...
Next days i will check the performance of this thing ...

Fits the Wemotec MINI 70mm fan just PERFECT! Its a snug fit, but you'd be amazed how nice the flush fitting is... No alteration is required, but when you push the face plate thru, you need to initially push it on an angle.



On 5s 4000mah:

74 amps steady

~1250 watts

19.XX volts

Temp after 30 secs: ~66 deg on surface.



Would be good for short bursts on 5s IMO.



Haven't measured thrust yet.
