Hobbywing Castle 5th Scale Motor Teardown 

Just wanted to say thank you from those of us that are new to the hobby and looking to learn more about motors in general.

Interesting video! However, I have a couple of points for you. 1. Larger bearings do not necessarily mean better bearings. There are several grades of bearings (Google "ABEC ratings"). A smaller bearing with higher ABEC rating could have lower mechanical losses than a larger bearing with a lower rating. This is usually a cost trade. Both probably have similar rolling resistance numbers which would imply that the castle bearing may actually be a higher-end / more expensive unit. Hobbywing probably went with a larger over-sized unit to get similar performance at a lower price point. 2. Rubber seals tend to have more mechanical losses than metal seals. They do provide a better debris barrier, but that comes at a cost to overall efficiency. Side note: Most bearings (regardless of seal materials) are packed with grease that repels water, so any water that makes its way past the debris shield will probably just be thrown out of the bearing race. This means that the water (and debris) that does make itself into the core of an operating motor will probably settle into other places and begin to collect near the moving parts. So, you should probably still tear down and clean either motor periodically if you run in wet/muddy conditions a lot. 3. The difference in rotor length is important, but the overall strength of the magnets is the key factor. It looked like you had to fight harder with the Castle magnet, so is it safe to guess it was the strongest? A stronger magnet generally means a more efficient motor which will put more real-world power to the ground. Also, since you had the motors apart anyway, it would have been interesting to measure rotor weight. For example. if the Castle rotor weighed about the same as the Hobbywing, but had a much stronger magnet, that would show that Castle used a higher grade magnet material which would imply a more efficient/powerful motor. 4. Wire diameter doesn't mean much without knowing the grade of copper used and the overall winding strategy. Generally thicker wire has less resistance per length, but a thin wire made of better grade copper may have lower resistance than a thicker, low-grade wire. Also some motor makers use several strands in parallel to get the same result as a thicker strand. It would have been interesting to see you measure the resistance of the motor coils, but this usually requires a special meter since their resistances are usually really, really low. Lower resistance coils would produce less waste heat and allow the motor to pull more current (which usually means more torque and better overall efficiency). Keep up the great content!

Very interesting Vid Mr. Exocaged, i'm excited and thank you for the look in this big engines. By the way...great Job man,very good that there are people like you! Keep on rock'n' and stay smooth'n'cool 🤘😎🤘

As usual great video 👍🏾🙏🏾

Thanks for the technical breakdown. If I could only watch one channel, it would be Exocaged RC.

After the burial intro sold me right away.

great video bud. keep the good job.

Awesome video wow some suprises there

Good video!

I ran the hobbywing on 12s and it's a monster

Another nice video. Very informative. Idea, maybe kind of trace the magnet on a piece of paper and measure the lines.

Dam Man U always have great vids and awesome info thanks for sharing this knowledge 👍👍👊🏻👊🏻 5:53

great video, however the best way to identify motors are by their physical size (diameter & height, example Hobbywing 56113, ...800kV motor) the kv can be the same across the board for tiny drone motors to large motors powering tesla vehicles so it confused us in the beginning. Keep up the great work man!

Great vid, thanks for taking the time to make this video. I just picked up an ezrun 8 2200KV combo today. As for the wire winding, the thinner & more wound wire, the more torque and less top end speed, the thicker the wires & less wound wires, the less torque & higher end speed. So looks like the castle will have a bit more 'oomph' at take off, but sacrifice a bit of top end speed. I would love to see a comparison of the 2200kv motors of each, the 1515 castle & the 4274 hobbywing. Thanks again for the info, I will definitely send a shout out to your channel when I do the unboxing video of my ezrun 8 combo. 👍👍

Hey I just calipered a hobbystar rotor and it was a whopping 27.9mm diameter. I could physically see it was larger than the castle I have.

Very cool video 😀 I think the 1100kv would be a good choice for the Losi Super Baja Rey 👍

The bigger bearing doesn't necessarily make them better it's the quality of the bearing itself that means is going to last or not last

Was never a castle fan but i do own a bunch of hobbywing stuff! For the money i would go with the hobbywing hands down

Thanks for the great info. I purchased a max6 esc and a Hobbywing 1100kv motor for my Redcat Rampage XBE 1/5. What pinion and spur gear should I use?

Looks good for an e-scooter setup

That hobbywing just looks higher quality overall.. I think Castle made changes on the newer 800KV didn't it?

Rubber shielded bearings may be a little better at keeping dirt out but metal shielded have less resistance so in terms of who win in the bearing department, Id have to say Castle does. At high RPM youre going to want less resistance.

I'm was looking at hobbywing for the Udr I'm building, I'll be mainly running 4s and 6s once in a blue moon. Which one should I choose?

You need plastic calipers from Harbor-freight

I have Hobbywing and Castle on multiple rc cars I have and have come to the conclusion that castle esc's are a gamble might get a good one might get a paperweight. On the other hand Hobbywing esc's are solid, can be abused and still show up for the race. Both companies have solid motors but I think Castle is a little better in the power department on motors so I started running Hobbywing esc and Castle motors. Getting to this conclusion cost me about $1000 in Castle esc's which left me with a bad taste in my mouth for that company.

To be honest I’ve completely gone away from castle I think their stuff has gone down hill the last couple of years. I’ve had 2 esc’s go out on me with very little use and stress and the motors are decent but it just seems their quality control isn’t what it was several years ago. I switched all my big bashers over to hobbywings and have been very happy with them so far.

Hey Joe @3:44 do we know or could you help me with the specs of that shim/bushing I ran 8s on 1650kv version and that part now has dimples and when placed back within the motor it now sounds like I have rice paper at certain rpm’s on bench test wouldn’t put to ground at that instance 😬I’ve looked 🥸and can not find the spec n that so I’m hoping that those cans maybe that could also be not good but maybe you know Thank you Joe 🥇

Thanks for the info Bro...I sub your page...

The thinner the copper wire the more resistance maybe ? , So the thicker hobby wing windings may flow electricity better ?

What do you recommend for a monster xmaxx with trencher, i need it fast with torque? max5 with 800 kv ?

Hobbywing is higher quality, great info, great vid, just made my choice easier. 👍🏼

I got stock brushless in my slash platinum vxl system I’m just a back yard badger 2s lips my big issue is my yard has thick grass so what do I need to do to get cooler longer runs out of my slash 4x4 plat

Those are serial numbers and they're different on every individual motor.

Whenever I do that it sure makes me wish I had a non magnetic caliper. Some stainless is not magnetic.

I would like to see you compare the hobby star motor to these hobbywing.

Sorry if this a dumb question. Why do these big motors have such low KV? I would have thought they would be around 4,000. Thanks

If you wanna go above 8S then get the Leopard 58113 700kv imo

One of the reasons castle may use a standard bearings,is that rubber bearings cause more resistance.MoreResistance more heat

Joe How do you open the max6 motors please I can not remove the end bells to get at the bearings

How is the hobbywing rotor Kevlar wrapped and castle is not...should be the other way around

I'll take hobby wing all day, as far as magnet size don't mean much, it's the quality of the magnet. Also I've been told the castle are better for top end and hobby wing for torque, just a general assessment. I also think it was quite obvious the hobby wing was just straight built better.

Nice how much

Same factory makes all them motors they make hacker as well

HW customer service is absolutely abhorent...I don't care what the quality difference wouldn't matter because they're an awful company to deal with. Castle is fantastic in that regard and their motors are excellent.

Less is more? Why 800vk is bigger?.

thinner coils i would guess would have less resistance which equals more rpm and less torque, so i guess if both are running on 8s the hobbywing would have maybe a tab more, but then again the rotor is a tab long on castle, and the esc could have a factor to, if both motors are on the same esc and same cells i would say they are pretty equal, but the castle may have a tab more rpm due to thinner wire. one last thing is that the castle is rated for 12 cells so it will have more rpm and torque compared to the max 8 on the hobbywing. either way, both are monster motors, i know castle is about 10 hp and i bet hobbywing is close behind because of the max 8 cell. another thing to think about the castle mamba xlx is rated for 8 cells. long story short go with which brand you are more biased to i guess, or go with price

Thic whires are better. Power Goes through it easyer (lower resistance)

You are supposed to zero out after every measurement.

Hobby wings better thicker wires better better magnet and rotors

"I am not a motor expert" Case closed.

too often you said i don't know... about features that should be explained in a comparison video.

Really? Plastic calipers are cheap. You're welcome.

If you dont know..then why make a video?? Total waste of time
