Hi ,Bea,I looked at fan you have found it is 68mm in dia. and uses a scremer motor which i cannot find on that site,the motor they recomend is 28mm dia. to fit fan and the 1400 they mention i think would be the kv rating of motor which means it is designed to make 1400 rpm for every volt used ,only 19600 rpm ,not enough as this fan needs to mak 30 to 40 thousand rpm so i am a little confused. most of the fans i use are from Hobby King much cheaper but need balacing.Hope this helps ,regards Ken Jack
