40mm 12-Blade EDF Ducted Fan with 3S/4S 1413-KV5000 Brushless Outrunner Motor Model Jet Aircraft

Very powerful , with the right battery

Great little EDF, well made and worth the money. Powerful little buggers. Recommended.

holy cow, this thing is a monster. Who would have thought that a motor that size could make so much thrust.

The hot 40mm EDF to get now. Measured specs are a bit optimistic. Actual weight is 42.1gr vs 40.0gr claimed.Max static thrust I can coax out of it @12.5VDC is 340gr vs claimed 360gr. Still far more efficient than the Dr. MadThrust 40mm EDF, and nicer sound.Can't wait to try it in the air.

Honestly would have been happy with the way it performed on 3s but holy how this thing genuinely impressive on 4s.

Hobbies great edf lots of power in a small package will fly a 64mm jet like the freewing panther or F-86 on 3-4 s packs very efficiently w/power to spare speeds of 70-80mph great for small fields

For a 40mm, this edf is super efficient and sounds great !

40mm seams like a good ratio of compact size and still enough blade area to move a lot of air. I'm not using it for an airplane I just got sick of all the wimpy overpriced personal fans out there and made my own. ESC are so cheap these days and you just need a $2 servo tester then make a switch by making a break in the power wire and something bendy like a broken prop blade. This can blow the sweat right off your skin and inflate your clothes in the most refreshing way lol. Anyways great little unit.
