I have one of these on a wing, running a 6040 KingKong prop, a 4s 1800mah Turnigy nano-tech battery and a 45Amp YEP ESC.
I measured the thrust on a home-made rig and I'm getting 1420g of thrust @ 36A.
They're a great motor.
Sweet review, looking forward to seeing them in action.
Only thing I would have liked would have been to see some numbers that compared it to the previous emax motors for those props you tested in your controlled setup.
Anyways, awesome content. Keep it up!
Yeah, I would have done that, but all of my old emax motors are, well old. My magnets aren't are strong anymore after a year so numbers wouldn't be fair. I have done videos using the old emax motors if you want to check it out.
love my 2600kv RS on a Theory X
I have some Hyperlite 2206 2522kv on the way for a race build =D
The RCAddict Power :) I wanna see those
The RCAddict oh wow that's the first time I've ever seen those Motors they are colorful LOL
Ultimatevapor918 Haha yeah. Fully blue build ;D
Finally i have been waiting after i saw instagram
=D
Hello, it's a really nice video. I want to ask you about the lipo battery. I have the same motors for our FPV racing drone. But I really didn't catch what is "C". What can ı use as a lipo battery? It must be a 3S battery because my ESC supports only 3S so, My battery must supports 3s and a high "C" value. What do u think about the value of "C". Is 11.1 V 3S Lipo - Battery 2800 mAh 35C" enough for my FPV drone.
Apparently the 2600kv version has an unusually high amount of torque.
Yep, these N52SH arc magents and .15mm laminations produce awesome results.
Let’s do a resume of this video with current props! I love this motor!
It's outdated now.
The RCAddict you should have told me two days ago before I bought it! Haha so what’s the new best motor around this size?
I mean it's still a fine motor, especially for 2205, but I pretty much only use 2207 or 2306 now.
Which prop will give longer flight time on 3s ?
For longer flight time 2 blade prop is good or 3 blade?
Total weight of drone qav 250 is about 900g with 6200 mah 3s 40c lipo.
I would say these motors perform a litter better but if you already have v1 it's not worth swapping out. They also set lower than originals so if you have fat escs on top of arm might have issues.
Yes these are not a "oh my god, you have to upgrade!" but if you havent bought the motors yet I would certainly go for these.
its great to have some comparisons like this,
Yeah, might get some 2600kv versions to try out.
why do you no proper pilots like yourself use kingkong 5040x3 props... they look a lot like hq 5040x3's
They look like them, but they aren't haha. HQ have perfect balance and perform like no other.
Awesome video, have you shown a video of newer props please Seth
I stopped doing thrust tests
Great video! Are you happy with the thrust stand? I have been considering getting one. Keep up the great work.
It probably isn't the most accurate, but it does alright :) I like it, except the mounting block is like 6mm thick so normal screws don't work! grrrr
thanks great video. Are you running 4s batt on motor??
yes
This motor has nylock nuts?
nicely done! You don't have a set of cyclones kicking about do you? Id like to see where they fit in amongst these :)
Thanks. Unfortunately no :/ I have some of the new DYS 5042 Tri props on the way to test though (clones of the German Shrubkaft ones)
have you seen lumenier have a new line of props too? So many props out there now!
No, I don't think I have. Was interested in the HQV1S but after Steele said efficient not powerful that died lol
How do you feel about EMAX RS2205S 2600KV in 2018? Or should i buy AOKFLY RV2306 2650KV instead? or Cheapest "good" DYS Shu/Wei? .. (Budget is my main concern / first build / freestyle) TY!
I would go with the DYS motors for sure, 2306 or 2207 if possible.
thank you sir!
pls review the LD power 2450kv!!
Great test - you showed the data in a very useful manner!
I have a set of these behind me (first motors) and noticed how much force I need to twist the propellers down the shaft (and back up). Is this to be expected with the intended propellers (5mm mounting hole)?
The propellers are Kingkong 5045x3, 5040x2 and some 5045x2 that came with my Martian 2 frame.
If the prop is cheaper, like a DAL of KingKong, I find sometimes the dimensions are the slightest bit off causing them to be super tight on the shaft. I have never had a problem with HQs not going on.
Alright, sweet. With that solid shaft, there's no way I'll accidently bend/damage it by carefully twisting the propellers on and off - correct?
Wind1000100 Yeah, practically impossible for you to bend the shaft by hand. Maybe throwing the quad against a wall haha
Thanks heaps of your help!
I have one more question - how tight should the prop nut be? Significantly tighter than by hand or just a little bit, until it stops moving with not too much force?
Wind1000100 Tighten it as much as you can until it stops turning. If you can hold the motor and twist the prop at all try to get it tighter.
Could i run these With littlebee 20a's. currently have no name 2205 2300kv's with Dal 5046 tri. I Use 1550 75c 3s. And 1550 4s 45c+
Yeah man, will take them just fine.
the 2600kv version just came on the miniquadtestbench site with more than 1500g thrust on a 5inch! And a comment was that despite the high kv, it had more than sufficiant torque... Your thoughts?
Yes, these motors are VERY torquey, so while the 2300kv will have more torque, the 2600 is still adequate. With over 1200g at only 29amps I am VERY happy with these as that is basically exactly what I was looking for in a motor.
The RCAddict the same reason im getting the 2300kv :) also nice vid(forgot to say) :D
How does high kv fly vs low kv? Im trying to do serious racing, and im trying to debate wheter to go 2600kv or 2300kv. 2600kv will be on hq props, and the 2300 will be on avan r flows. What do you think?
I mean it really depends on the rest of your setup, your skill level, and how you fly in general.
@@TheRCAddict I have it all planned out lol. I'm a beginner, but I bought a qx7 and velocidrone and I've been using that for two weeks, I'd say I can fly alright in acro. My setup will be :FC: CLracing f4
ESC: racerstar rev35
Frame: campfirequads cf-1
Motors: dys samguks
Camera: foxeer micro arrow
Vtx: RDQ mach 2
Reciver: frsky xm+
I want to do racing, not really going to focus on freestyle, and the estimated dry weight will be about 300 grams. Probably a little more. I fly fast, and low to the ground, i dont do a lot of cruising. I was also thinking about getting the 2300kvs and running them on 5s, but im concerned about the motors exploding
Starting out that should be more than enough for you, especially flying a track. Turning and elevation changes make you slow way down.
How bad will these kill my graphenes 45c batteries? Exact same as yours but 45c
Depends on the prop and how you fly. Should be fine though.
compared with f60 t-motor ? are they close? or is it with a F40?
Well, that is not really fair as the F60 are 2306 2450kv I think haha. And F40 are 2305 2600kv. These are fantastic motors for their class.
lol I just found two sets of these in a box Emax sent me a long time ago. I believe they are prototype versions because they are 2400kv.. I'm going to build me a QAV210 I have laying around and a QAV-XS that I never built.. they are going on those two builds right now.. I have a few Hyperlite F4 boards that need a home and some Littlebee 30a Blheli_S escs... just build me out two play around LOS builds.. Hell I may grab some 3mm carbon and the cbc router and make me a set of arms for the qav210 to clear 6 inch props. hell I have some Tattu 4s 1800 45c packs that sent me that I haven't used. yup I'm building me a 6in LOS build.
Haha finding stuff you didn't know about it always good lol
Are these for a specific frame size or blade size? Gb130? 3 inch or 5inch? Noob question but it's info overload for me right now.
I literally posted this comment after herring my question. Doh!
No worries. These motors are specifically made for a 5inch prop, but could still work on 4 or 6 inch.
Hi!
ThanX for the great video.
Question.. I just got the new littlebee favourites 20s amp esc's. Which would be the better match, the 2205s 2300kv or 2600kv?
ThanQ in advance : ]
There is no "better" match for an esc I would say. I mean the 2300kv will pull less current and some will argue you need 30a escs for strogner motors or higher KVs, but I literally always fly 20a, and just yesterday put several flights through on these RS2205S 2600kv with DAL cyclone V2 (T5046) and bascially full throttle flights, draining my entire battery in 1:30 or less, an d they didn't even get warm.
Wow! Ok so im in my way to my local store to get the 2300kv 2205s!
ThanX for the useful info BuDi :]
Gogi Fire Ok, they should be plenty powerful enough :)
Lol cheers!
The motors are definitely quality!
All connected today and then one esc burst into flames on the first test flight! :/
Going back tomorrow for a replacement! I let you know how it goes.. Fingers crossed :]
Gogi Fire Dang :( Must have had a short on it somewhere.
did they fixed the magnet glue coming off issue yet?
I never had any issue with any of mine.
ive heard about quite a few reports that they come loose but only on the steel shaft model. some reports found on the multicopters reddit
They are all steel shaft. I think I read that they said there was one bad batch
the RS2205 non S are steel too?
Bell and threaded Shaft is one piece and looks like aluminium.
theres a steel shaft inside, but it doesnt go all the way up to the threads.
Oh no only the S versions. I didn't know people still bought the old version. Haven't seen them in a while.
what battery are you using on your actual quad with these? A single 1300 graphene battery enough?
Yep, the 1300mah Turnigy 65C graphene packs. 4s
The RCAddict how good are those graphene 1300 4s packs? Debating which 4s batteries to get and considering getting a couple of those
I really like them.
Dude, nice and clean vid. Do I need a 35a esc for dal 5045 or 30a is safe?
You are perfectly fine on 20a. These are absolute peak numbers plus it's on the bench. Going to be much lower in flight.
Thank you :)
I can confirm this. My build is using Dys 20A, they are not even hot after flying with 3s.
I had crash and think the bell is bad now on emax 2306/2400kv and since no bells avaliable i may have to find other motors, have you ever heard or tried the mb=multicopter builders that are brother hobby there 2207/2400kv im looking at but my quad with lipo,cam,fpv cam ect is 700g weight so not sure what to go with i really did like the emax 2306 but after a 5ft offground hitting grassy field it messed up motor u can turn motor and bell is got slightly high and low gap between base and bottom of bell.
Emax might actually be supplying new bells soon, as they do for the RS 2205S Series of motors, though just a guess. 700g is very heavy though, what are you running?
5" alien with f4 flightcontroller,gopro hero3 with 3d mount,tramp vtx,x4r receiver,rotor riot fpv camera, run either dinogy lipo or graphene and its heavy
What lipo are you running? 700g is crazy heavy for that. Should be ~600
thats dinogy 70c 4s
weighs like 505g with props,gopro 3,vtx,rx,motors,esc esc no lipo and then 700g with lipo on 5" quad
Emax rs2205 2300kv can support 6s?
Possibly, but I would highly recommend against it.
Can this be used in a rcplane?
I don't see why not
Yeah, probably not the ideal motor though as don't most wings use 6-7 inch props, and larger plane models arouns 8-12 inch? This motor is optimized for 5 inch.
it really depends on what you want to put it in
are these motors both ccw and cw
Nope, all CW threaded. Was not aware at the time of the video
The RCAddict I have 4 and wasn't sure if i could use them if there all cw. so its ok to reverse 2 for ccw?
mark rankin Yep, that only refers to the thread. So all the nuts will tighten to the right.
Cheers was panicking there lol
;)
You got mail. ;)
Got it!
