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?

What is the lightest motor I can get for this fan for 3-4s?
 CReal 19 points
I was looking at the Turnigy 450 H2218 3200kv heli motor for 3s. Is that viable or should I go for the 2500kv?
 George 13 points
the fan is suitable for motor 3200 kv and below..for 3 cell..and 4 cell is 3000kv and below. I have burn out my lander motor 3900kv use this fan with 4cell..

What is the length of the duct and the length from the cowl to the end of the motor when a Turnigy 2855-2800 is connected?

Can somebody with enough experience confirm if this is a 70mm ChangeSun v3?
 magnusEl 1410 points
Well, it is a ChangeSun fan, but with the V1 housing and V3 collet adapters.
 magnusEl 1410 points
...and that would make it a V2... I just remembered that the V2 was just new adapters so thats what it is.

v3 has more stators and will fit the dr mad thrust 29.5mm motors .....this will only fit a 28mm motor
 Straight Up 868 points
Thanks guys! I wasn't even aware there was a V1, V2 or V3! I plan to use the Dr Mad Thrust motors so I would have been disappointed to learn they don't fit!

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!
