The performance of Electric Ducted Fans depend heavily on the inlet and thrust tube design. I sat down to get hard numbers on an EDFs static thrust performance with different configurations. Tldw: my testing showed that proper design can gain you up to 25% of the Thrust an EDF makes! We used an FMS 64mm EDF, 28-36 size motor, 3300kv, running off a 2200 mAh 4 cell battery from Spektrum, 30C discharge. #airplane #aviation #design #engineering #science #remotecontrol #electricfans #rcplane #scratchbuild
