"ChangeSun" 90mm EDF ???


Hello,
I very interested in the "ChangeSun 90mm-5 Fan" EDF (http://www.x-flight.com.hk/index.php?p=6&id=29&lang=en# ),
do me impression the rotor design ,resembles very with Schübeler-fan (copied in the 5-blade version ?).
Somebody knows that ? or has experience with this 90mm fan?

thanks

saw this video
ELE r.wmv (1 min 29 sec)
on this xflight page http://www.x-flight.com.hk/index.php?p=6&id=24&lang=en they look the same as the eflight electric retracts. i wonder if they held up ok in what seems to be a Tam F-16.

i wonder is this entire set will fit into the small sapac hawk http://www.x-flight.com.hk/index.php...&more=&lang=en mayb even the bigger one when it comes out.

ChangeSun 90mm is just a little heavy (140g) , than the Midi-Fan (100g). I think that design of rotor it's perfect (quality-?), but I can not find anywhere and read what it's real static thrust, anyone any opinion ?

i would really like to buy one of them pretty cheap and they looking pretty good.
but i really dont want to end up with a unbalanced rotor.
Is there nobody who has any experience with this fan ?
