Arrma Kraton Upgrade FAIL | Rocket 6S Brushless Motor

Upgrade, maybe not an upgrade?
The price on this motor seemed too good to be true. Here is the link: amzn.to/3hIiKBc
Half price of the stock motor: amzn.to/2V0mPqw
82mm can, 1900kv - such a great deal for less than $60, right...right?
Except for that small part I didn't notice...BOAT.
Follow along as I disassemble this motor, check out what it looks like inside vs the stock Arrma BLX motor and do an initial test.
Internals vs the stock BLX
4S speed runs with both motors
General bashability test with both.
If you stick around long enough through the video, you get to see some jumps and backflips at the end!
Having seen this, which one would you run?

great vid, it's nice seeing what's inside

[@RoadsideRC]

Thank you!

[@jrc-fabs1634]

Looks pretty good to me! Cool bash dude!

[@RoadsideRC]

Thanks! We will see how it goes.

[@islandrc-duke1972]

nice,looks like it did pretty good,cool bashing

[@RoadsideRC]

Thanks!

[@GreatLakesRC]

Nice that you were able to swap the endcaps 👍 I like the bigger motors for that low end torque 💪 Check out the hobbystar motors. Similar price and very good performance 👌

[@RoadsideRC]

Yes, I have a feeling this will get swapped out soon...but might as well run it while I can!

[@BarstoneRC]

Great video man motor might last for a little bit unless you get mud or water LOL

[@RoadsideRC]

We shall see! I was going to go to the racetrack this weekend, but I am thinking that dusty environment will kill it for sure!

[@rcworkbench4405]

Nice! We just tried a colossus in the Kraton with a Mamba X. As your shirt said... MEH. Got another combo coming soon.

[@RoadsideRC]

What combo are you going with now?

[@billyb5057]

does not look like a mistake to me did you check if the new motor run hot was wondering if the holes at each end were to ventolate the heat away although muck as you said would get inside the motor *thumbs up like 👍Au 👍you got a full view too*

[@RoadsideRC]

Yes, I would certainly hope the heat would dissipate easier. Just a big concern on debris in there!

[@Ryndel]

Great vid! Did it end up being cooler? I was thinking of using this for an on road arrma heh.

[@RoadsideRC]

I don't think it did. I believe this might have been a fail all around.

[@Ryndel]

@@RoadsideRC damn. Thanks for testing out though!

[@country0800]

just wrap panty hose around the motor. water wont hurt it and the panty hose will keep all dirt out. itll work I've done it before

[@RoadsideRC]

Nice! Thanks for the tip! I bet that would work!

[@KaizerTest]

I use a lot of cheap motors like Surpass which is the same company who builds the Rocket motors. I find they are reliable and can take some abuse. But yours being open like that...just keep it out of the wet and mud and I bet it lasts a good while.

[@RoadsideRC]

So far, so good. Just recently had another bash session with it and it kept right on going!

[@RichD]

Nice boat.. motor.

[@RoadsideRC]

:)

[@rcpatapouf]

also on aliexpress you can get 4282 4292 motor ( you will need to just change the motor connectors) with really longer rotor ! and for less 50 usd it's a sealed can obviously

[@RoadsideRC]

Yes! I would love to try the 4292!!!! Thanks for the tip!

[@rcpatapouf]

@@RoadsideRC I got two of them, they seem to have plenty of torque ! I'm just waiting to receive my esc to test them

[@jrc-fabs1634]

Is aliexpress ship from China though?

[@RCVOODOO]

nice hope it lasts a while , normally if they are junk they last about 5 mins .

[@RoadsideRC]

Well heck, I have more than that out of it so far!!! I'll count myself as lucky! :)

[@RCVOODOO]

@@RoadsideRC yea it made it past the first 5 mins it should be good to go

[@paulrakis]

Nice sonos that a better motor then the stock BLX ? Or about the same.

[@RoadsideRC]

I would stick with the stock BLX compared to this motor.

[@paulrakis]

@@RoadsideRC Kool thanks bro. Yeh if I ever upgrade my system would be the Castle and Mamba X

[@OverMoster]

Looking at picking up a 520kv rocket motor, how has this held up?

[@RoadsideRC]

It actually still lives to this day! Absolutely surprises me.

[@JoeOvercoat]

All my boat motors are sealed (all brushless). I thought that “Boat” meant it needed a water jacket.

[@RoadsideRC]

You might be correct....I honestly am not sure.

Thank you!

[@joshchatwin8569]

I was going to get one of these are they worth it

[@RoadsideRC]

I would not suggest it.

[@xKevmachinex]

got a 4092 1730 kv coming for my 1/8th scale zd racing pirates 3. I will post a video when I get it so you can see, not sure if you ever tried the 4092 yet or not. I currently have a 4076 but it has not much low torque, cogs in grass on take off, lots of power once it gets going thou.

[@RoadsideRC]

Thanks! I'll be interested in hearing how it does!

[@xKevmachinex]

@@RoadsideRC thx still waiting on parts. and its a 1530kv motor. god help my drive system hope it can handle all the torque. may have to do some throttle mapping.

[@xKevmachinex]

Follow up, thing has been running great for 8 months. I got probably 100 hours on the motor, but only even ran 3s on it. I just ordered a 4s battery 3 days ago so lets see if it can survive the same time on 4s. It was only a $50 usd motor and I mean I am happy with it. I have never done maintenence on it, don't even know how. do you recommend anything for the motor maintenance? can I put a few drops of oil in the motor? i was scared this would just make dust stick to it and stuff.

[@RoadsideRC]

That is great! The motors are meant to be maintenance free.

[@xKevmachinex]

@@RoadsideRC thats great. one more question if you don't mind i asked a few other people and tried researching it but no luck. My motor says its max amperage is 130a, my esc is 120a, and the batteries I have been using to date, which are 8400mah 3s 120c, have worked perfect. according to online calculators those batteries can do 1000Amp, I don't know how thats possible but thats what they say. I ordered a new 4s battery, this will be my first time running a 4s, and i didn't read the fine print before ordering, but its a 7000mah 4s and only 35c, doing the calculations Im getting 245A this battery can do, that's only 1/4 of my 3s lipos. I guess my question is, does that mean I will only have 1/4 power? or because my motor only uses 130A none of those figures matter, as long as the motor is getting the power it requires? so then is buying a higher C and amperage battery wasted money? I know they say you should have a 30% overhead, but my 3s lipo's are 1000AMPs lol that seems overkill, I feel like theres part of the equation im missing haha, thanks sorry for the length.

[@maximumrpmrc2312]

👍👍

[@RoadsideRC]

Thanks.

[@phil_4young]

Check the bearings. If you have any bearings going bad it can heat up fast

[@RoadsideRC]

That makes sense! Thank you.

[@RoadsideRC]

That makes sense! Thank you.

[@boxboy011]

Longer can means more torque not more speed!

[@RoadsideRC]

YES! But...my old motor was getting worn out, so I thought there might be a little difference just from that aspect. I was a little surprised to see that the internals of the motor were unfortunately roughly the same dimensions.... Get what I pay for I guess!

[@jdnic1]

1900kv is not an upgrade since the stock is like 2050kv. You probably just get a bit more torque from the motor but that's it. You can probably put a bigger pinion to take advantage of the torque.

[@RoadsideRC]

Higher KV does not mean upgrade either. Great example: I went from 1600kv to 980kv in my X-maxx...and it was INSANE! Yes, gearing needs to be changed to match the motor. In this example, I was going after exactly what you said - more torque. I got similar speed, but with a longer motor can that provided more torque.

[@karltan9461]

lol. this is a motor for a RC boat, thats why its open like that. Does nobody here actually know this?

[@RoadsideRC]

Yes, it clearly said in the listing that it was for a boat. But - I wanted to see what would happen. That motor ran for over a year!

[@karltan9461]

@@RoadsideRC nice. It'll run, just all the dust and crap gets in😂
