You need to go to Slomo777 and ask the question. He seems to be very up on fan motors being one of the best German high speed artists. He lists all of the fan motors on the Alley Cat thread, says the K & B is a little puney on power, but you have it, so turn it up. I would start with the a apc 12 or 11 X 10 and cut down to 10.5 X 10 and try for 20K. Prop given is conservatilve by a bunch. Let the Bergmistger guide you! Let me know how this thing does, know of one for sale!
