Hi John Sometimes it is very tricky to get the nut loose or the cone off. On a 90mm DF the treaded part in front of the nut was too short for two slim nuts. I tried the M3 inside hole with a screw and a nut. I came always loose. I put some instant glue to it. This time the nut holding the rotor came loose. Put all the alumiunum parts in aceton. That cleaned off the instant glue. Good luck Charlie

IS the 10 blade high performance edf unit thrust sufficient for take off, if yes then how much mAh battery would be ideal along with charger please suggest soon!!

You didn't give us much to go on. What plane are you trying to take off? What does it weigh? How long would you like to fly? Are you flying from grass or a smooth surface?

Hello, is it possible to connect this 10 blade... in a "Durafly™* D.H.100 Vampire Mk6 EDF Jet " for a better sound ? Thank's

Cont. : Usable with original Outrunner Brushless Motor (2700kv 2836) and original ESC 45 A ? Or is it necessary to change the motor for a "2826D 3000kv Outrunner Brushless Motor (660W)" or "Turnigy L2855-2800 EDF Outrunner (630w)" and change the ECS for a 60 or 80 A ? Difficult... Best regards.

Gilou, The motor in the vampire will not work with this as it has too many blades for the motor The best suited motor is the dr mad thrust 3000kv on 4s1p and use a 100 amp esc it will turn you vampire into a sweet sounding rocket Gooseman

iv fitted my vampire with a dr mad thrust 2200kv 10 blade 70mm edf, on 5000ma 6s , if you want it fast, this is what you need, just have to open up a bit more air intake for the edf as it is so hungry to swallow air, but spits it out the back really hard, 2.45 kg of thrust, more that enough but boy does she howl !

will this fit into a rc powers f35 jet? i have a prop in at the moment this should make it sound more realistic

A mate of mine fitted a 70mm fan into the RCPowers Eurofighter, and it's awesome. What does the F35 currently weigh? How long is it, and what wingspan?
 ooare123 5 points
109cm long 82cm wingspan 780 g weight thanks for reply
 Straight Up 886 points
Sorry for late reply. This fan will likely work very well in your F35.

1 thumbs up!
VERY VERY Nice sounding fan, here are the thrust numbers using HKs L2855-2100kv motor..........6S 4500 25C \ Vm: 21.63 \ Ap: 68.36 \ Wp: 1538.74 \ Thrust (Kg) 2.2 AND 4S 3300 25C \ Vm: 14.18 Ap: 35.32 \ Wp: 534.5 \ Thrust (kg): 1.3 AND 5S 4400 65C \ Vm: 18.82 Ap: 54.70 \ Wp: 1067.10 \ Thrust (kg): 1.8. That is great thrust and great sounding here's a video ( watch?v=coa9aMKyp0s ), no that is not a turbine that is this fan spooled up slow before take off.

Great sounding fan, what the 70mm EDF jets have been missing. I'm using this with a Turnigy L2855-2800kv EDF on 4S 35C 2650 Nanotech in a foamie F-16 (also here on HK). I'm getting around 750watts at 55amps. Some things to watch for are 1/ Housing is flimsy so becareful how much power you intend to run 2/ sounds much better when properly balanced although its not too bad as it is 3/ make sure you tighten the fan properly to the adapter or it might slip 4/ don't use the spinner or it will throw out the balance. Definitely worth the money for the sound although it won't break any land speed records....

The most radical change in 70mm EDFs for a while. Amazingly quiet and respectable thrust. No other EDF of similar price is so refined and effective.

Run it with an L2855-2300kv on 4S and get 1.3 Kg of thrust or go to 5S and get 2.0Kg of thrust. I uploaded a video of this unit in a Durafly Vampire. It will not sound the same in every plane since the airframe ducts and exhaust play the major role in the sound being generated.

Well. after testing this fan i was amaised to find out that its not so good as afew ppl wrote in these revews. at 22 volts 30c 5000mah battery the fan gave onley 1200 grams of thrust that was without the intake rim but with open air intake and took 1000 watts. with the same motor that the reveweres used L2855 2100kv. i think that what afew ppl wrote here in the revew is wrong. it just can not be and its also not logycal. the regular 70mm 6$ 6 blde fan gave me 870 grams at 650 watts. and its not so diferent than that fan just afew more blades. by the way the saund is more plesant with the 10 blade

The Changesun is the revolution of the edf! Finally the only solved the problem of electrical configuration that remains the least expensive and most efficient ... ie, the noise! with this you get the feeling of having an aircraft jet airliner. Greetings and kisses you crazy spending by € 3,000 to € 5,000 per turbine kerosene! If it progresses technology obtaining lipo lighter and more resistant to high amperage will be a pleasure. Anyway, I'm going to 6s with Turnigy kv2100 54a with 1.4 and I get thrust. Using a 65c 2250mAh lipo with Atencion. Thanks HK!
