brand new 100mm Sapac Fan and Dynamax rotor with a Scorpian HK4035-800KV Motor.
The following is the specs of this Sapac 100mm fan with Scorpion 4035-800 KV as tested by Carl Rich
100.3mm Fan ID, 7901 mm square 58.3 Motor housing OD 2669 mm square FSA = 5232mm square = 81.5mm diameter exhaust 80% FSA = 4185.6 mm square = 73mm exhaust diameter FSA 60% = 63.2mm exhaust diameter Temperature 55F very low humidity in tropical Ohio.
HV 160A ESC settings Motor Timing 5 PWM 8Khz
100% FSA exhaust 12s 6500mAh 40C Thunder Power cells warmed to 90F Volts start 50.35v dropping to 44.34v, 134A holding, 221.2oz Thrust (13lbs 13.2oz), 6000 watts holding, 32,325rpm, 246mph efflux w/o moving pitot tube in the exhaust duct to find max efflux.
Notes; This fan makes significant efflux (highest I've ever tested) and quite a bit of thrust considering the FSA is just a little more than that of a typical 90mm fan (DS 51 is 5100mm square). Lower FSA would make it rather ideal for use where a jet's inlet ducting is a bit small for most 100mm fans. In a jet made for 100mm, 80% exhaust on 12s would likely drop the current to the 120A range and work fabulous with 5,000mAh packs. I tested the Sapac's larger 127mm fan w/650kv motor on the thrust stand and found that when I put it in the big Cermark Viper the current dropped 10Amps due to the fact that less air can get to the fan once placed in ducting when compared to the open face w/ inlet ring while on the thrust stand. Wires coming out of the side of the fan is a nice touch that makes for a clean thrust tube w/o a wire hole.
