I have one of the new DS94 HST fans for sale. It is the most powerful 128mm fan you can buy for a 12s set up. It is also rated to be run on as much as 14s if you need around 30lbs of thrust. You can buy one for $1210 plus shipping. Because the fan is not mass produced the lead time can be awhile. Mine took 3 months to arrive. I'm offering this one at $995 you pay what ever method of shipping you like. You can have it in a matter of days/whatever speed of shipping you pay for.

It is rated to just a touch under 24lbs of thrust on 12s at around 6500 watts. Best info available on Schuebeler's website. It is absolutely smooth from 0 to 100% throttle and very quiet due to the high blade count. The carbon fiber rotor is obviously a bit larger than a BVM 120mm rotor but weighs about 1/2 as much.

The fan has a total of 7 minutes of run time. The rotor blades were chipped but a brand new complete rotor has been received from Schuebeler and installed.

I have a pair of Castle Creations ICE HV160 V2 controllers also with 7 minutes of flight time each. Will sell at discount of 20% at $219/each.
