MTT EP9 2 Surpass KK Series 3660 Motors Tested

This Guy Is The King of Motor Testing Hands Down!

[@LawrenceTimme]

Thanks for the kind comment!

[@dannysdailys]

He certainly thinks he is. But if he won't test the motors at their maximum specs he's doing nothing. What's next? Testing a 6s motor at 2s? It doesn't matter now, I don't like his attitude. I've been building 100 mph 3s cars for 30 years and I'm not coming back. This is a fraud.

[@druscanam]

What's interesting is Surpass do make the 3660 in both 2900kv and 3800kv so I do wonder if they were just labeled incorrectly, and possiblity the reason why you got so cheap. Given the lower then expected amp draw of both it does seem like a possibility.

[@LawrenceTimme]

Yes I was thinking this could be the case. They both seem legit though.

[@druscanam]

@@LawrenceTimme Yeah I've owned and still owned a few surpass hobby and never had any problems with them. First one I owned was the rose and silver platinum series, a 2845 5000kv. I was super impressed with it, very smooth and powerful and have mostly brought surpass motors since. None have died on me despite that 2845 at one stage being completely underwater with all other electrics includeded the battery dying, but the motor was still strong. When I removed the motor out of the car, I pulled that one apart to clean all the dirt and grease out after over a year of abuse and impacts since it was rear mounted motor exposed to impact. When I put back together it ran a little hot, even without load. I probably could of kept and still ran it but decided to retire it since new ones are so cheap as I ended up putting a brushed system in that car to give to a kid as his first RC and didn't have any immediate use for that motor anyways. Since then I've owned blue can, platinum and KK series 2440, 2838, and 3665 motors and have not had any problems with any.

[@LawrenceTimme]

@@druscanam yes I have lots of there motors and they have mostly been great. Only real issue I had was a on the 4092 1650kv where all the screws came out the end cap and so the cap came off and the rotor got damaged.

[@LawrenceTimme]

@@druscanam kind of ironic isn't it. The 2000kv motor in my xray blew up after writing that comment 😢😢😢😢

[@druscanam]

@@LawrenceTimme Another good motor brand that punches well above its price range that is not made by surpass hobby (goolrc and Ocday made in surpass factory) is Ldpower. LDpower have been making well known race drone motors for a while but are not so much established in RC car motors yet. The two most common sizes I know of is the 3652 and a 3674 motor. I own two 1/10 2WD buggies of the same make and model, one has a hobbywing ezrun 3652 3300kv the other a 3652 3800kv LDpower. Obviously I was expecting the high kv motor to have a higher top speed due to higher rpm yet I was not expecting how much more punchy, smooth, refined and responsive it was compared to the hobbywing. Higher kv, same gearing yet seems to have more torque. Also stays cool too even after a 28min endurance track run (didn't quite last 30min) on 3S with thottle rate turned down to be about 2S power. And you can find these on AliExpress for peanuts. Haven't tried the 3674 size but next time I need a motor that size I will try the LDpower one for sure

[@hazimhilmi6284]

can i know what a different between surpass blue brushless and surpass red brushless?

[@romper4444]

The blue is the classic original v1 series and the red is a v2 the way I understand it

[@DinhNguyen-ki7lk]

I am still wondering what is the difference between the KK and Platinum versions? The only difference I've found is 4-pole 6-slot (KK) vs 4-pole 12-slot (Platinum), but i don't know what that means

[@LawrenceTimme]

I found the platinum to be a bit better but that might have just been luck

Hello i have a remote control boat and i want to find an electric motor with high power the boat weighs is 7 kg what engine do you suggest to reach an efficiency of somewhere around 50 kilometers? Thanks!!

[@LawrenceTimme]

Not a clue on boats. Sorry

[@Itsarealone]

I would like to see you do a test on the 3665 motors please? Just by judging these maybe the 3665 won't put out close to its rating as well unlike the 3650 motors you tested. I need to replace my 3660 3200kv spektrum motor that seized and looking at going to the surpass 3665 3500kv motor. So by the way these tested maybe the 3500 I want will end up being close to the 3200kv rating of the factory motor but with slightly more torque

[@LawrenceTimme]

I don't really have any cars or trucks that would fit a 3665 so its unlikely I am going to buy any. I will be doing some ESC testing though :)

[@Itsarealone]

@@LawrenceTimme no worries, those tests will be good to see

[@TastierBackInThe80s]

Thank you. You just saved me some money.

[@cesarguerra6039]

Hi Lawrence, do you know what would be on average the constant current draw for a surpass 3660 2600 kv motor? Using it for bashing arround. What C rating and capacity lipo battery you recommend to get at least 20 min playing time?thanks:)!

[@LawrenceTimme]

It depends completely on the gearing and weight of the car it's going in. Considering all the c ratings are fake, I'd recommend you get a decent brand of battery and 5000-6500mah. Stay away from cheap brands on Amazon or bangood even if someone on KZbin is shilling them.

[@cesarguerra6039]

Thanks for the advise Lawrence! I will buy it on local store then. Is there a simple way to measure the average current draw? So I can know more or less how much time i will have with 5O00 mah. Also, do you think i can reach at least 30 mph with 2s and 2600kv? Or should i go 3s. I have a gear ratio of 3.25 and car weights arround 1.9 kg(1/10 scale).

Hello Lawrence, greetings from Spain. I had just bought a 1/10 car DIY , Im wondering if I mount a 3570 instead of a 3650 will it fit? How I know it can fit. I read shaft is longer. Do I have to buy additional parts? Or it would be the same mounting any of both. thanks very much

[@LawrenceTimme]

The shaft of most 3670 is 5mm in diameter and most 3650 are 3.2mm diameter, so you probably can't get a pinion gear with the correct holes size for a 3670. Stock with the 3650.

[@cesarguerra6039]

@@LawrenceTimme ok, then for what scale is a 3670 recomended or meant to? A 1/8? Or is that its meant to fit in a 1/10 and the only solution owners apply is to find a pinion gear that fits? I bought a zd racing 10421 diy kit. If I have to stay with a surpass kk 3650 and i want to use 3s you would recommend 2600 kv or 3100? I will buy a 120A esc.

You tested those motors on 2s; so the KV wouldn't peak its max. Try another load test running on 3s then you'll have a better result!!

[@LawrenceTimme]

The motor doesn't increase in kv at higher voltage as the kv = rpm/voltage.

@@LawrenceTimme Oh really ? Then test your motors at 1 Volt and show us.

[@LawrenceTimme]

@@bretzeletouffeur7401 the motor tester only works at 2s voltage. The kv is constant value. Its rpm per volt. So the higher the voltage the faster it spins, obviously there is a minimum voltage that it requires to move, which is probably above 1v. Most manufacturers of motors test at a 2s voltage.
