USA warehouse now open. Our USA warehouse is now open! Low cost shipping and an ever growing variety make ordering from the US warehouse even better value!
Reliablity is fine. Only minor issue is to dismantle the fan evey 30 flights or so, to check that the motor mount screws are tight. The motor does get hot and blue loctite loosens up.
This motor can be used on 4S for around 42-45Amps and around 1.2Kg thrust. Useful for light(1.1Kg max) foamies.
Ideal. Many thanks for that. Could be a cheaper option than the Cyclones I use currently, of which the last two I bought had eccentrically machined shafts and are useless.
Yeah, I have one cyclone with a bad shaft. This L2855-2300kv is good for 4S & 5s. My comment above re heat, concerns 5S use. On 4S, it is not bothered.
It's brother, the L2855-2800kv is a better choice(300gr more thrust - 60amps) for 4S use.
So it is not an isolated issue with the Cyclones - mine are the 3.17mm type - the 4mm with the same specs. are fine.
Am trying to get shafts to replace them. Will let you know if I find any as replacement is easy. will also replace the e clips as they are chocolate soft. I have seen results from the 2800kv version of this one, but never catch it in stock. May just order a few of them and wait till they arrive. No hurry really.
Newbie here... so many talks about pulling 45-55 amps - this motor states it's good for up to 26 amps.. I'm not understanding something here... I want to put this in my F22 w/10 blade change sun fan blade... on 4s, can it handle it?
Yey you can! I Fly this setup in my vampire. You only need a 50A amps. I use a 4s 2650mah. Nice sound and good speed. The fan is awesome for this money!!!
So, if the motor states it's rated for 26 amps, but people are flying it around 45-55 amps... what can this motor handle? I know from other people setups on the F22, that this motor needs to handle that 45 amps constant....
i use this excellent performance/price brushless on a 70mm change-sun 10 blades with 4s 40c 2650 mah and it works perfect ! very low temperature great speed and about 5-6 minutes flight-time on a multiplex twister. nice turbine sound :)
There is a ton of info on the CS fan and some on this motor at RCGroups . c o m . Search for "Change Sun 10 blade 70mm" at the Electric Ducted Fan Jet Talk forum.
I Think this should be 6s as well, and why does the watt rating differ so much between the 3 versions of these motors 2100kv = 900W, 2300kv = 450W, 2800kv = 630W? I think the 2300kv one should be somewhere in between 630W and 900W
Difference is all abOut resistance, and amount of windings to get the desired kv Makes lower kv motors have less power handling. In the case of these 3 motors, they probably used different terminating methods (wye vs delta) to get to 2300kv, so the power handling is l
Yes there would be, as you take volts x amps to get watts. The 2100 is getting an additional 7.4 nominal volts to spin it.
So more volts on one would skew the watt readings compared to the others.
If memory serves me, spinning the CS 70 mm 10 blade fan, on 4S, the 2100 pulls 35 amps, the 2300 pulls 40.
So 518 watts for the 2100
And 592 for the 2300

good motor, i have this on a wingwarrior eslayer 48inch wing, and it rocks! running it on 3s3000, 6x5 prop, it runs smooth and cool, with hellalota a power.plus, the cone combined with a spinner looks awsome. i had a turnigy 2836-2350kv(Product=12919) before, its also a great powerhouse, but isnt rated for 4s . i cant wait to try this one on 4s.
Tested on 6S 22,2V (discharged) in 70mm SAPAC EDF (bad coolong environment, no cooling holes or intakes, housing prevent good cooling). Result (15 sec test): 1800g thrust, 55A, 1050W, 70-75°C. I assume 2000gplus thrust on fully charged battery, 1200Wplus but too high temperature, so the best power is around 800-1000W depending on temp and cooling environment. Anyway it is perfect motor for price. Sure it will be absolutely reliable on 5S, but I will try to handle temperature on 6S and power under 1000W.

Das sind schon gute motoren für Edf 70mm mit 60 amp Esc. Aber da ich mehrere zubehör (2 Edf motoren 2839 EDF Outrunner 2800kv,Turnigy L2855-2300 EDF Outrunner (450w),und Edf zubehör ,5 servos,70a SBecTurnigy Trust Esc,Turnigy Trust Programmcard usw.) im wert von 272,48 dollar besellt hab mit ungefähr 2 kilo musste ich die sachen von Zollamt abholen und musste 19pcnt mwst. bezahlen.hab 39.48 euro Zoll gebühren bezahlt..Bin total sauer..Also passt auf was ihr da bestellt.
Very happy nice upgrade for my rebel 70 jet used it with the upgrade fan available for hk

I purchased this motor to power one of the new 10 blade 70mm fans from Hobbyking. Before flying it in my L39, I bench tested it with 4s and 5s batteries. With 4s I was drawing 16 amps at full throttle, about 250 watts. Unfortunately, at this power level, the L39 will just not fly. With the 5s it drew 25 amps and flew about 50 yards. It just would not accelerate to a flying speed. I am flying at 4000 feet, so it might work better at sea level. I don't think you want to use this with a ducted fan and a 4s or maybe even a 5s battery. BTW I tried it with a 5 bladed fan and had the same result.
