The "best" 380 or smaller motor (rc18)
 

Hey guys. I'm looking to replace the oldish mamba 6800 in my rc18. I'm looking for a real power-house and high quality motor. I was originally going to replace it with a Wraith 7K, but it seems nobody sells them anymore.

Does anyone have any suggestions? I have very limited knowledge about hacker, neu and lehner motors so if anyone knows of any high quality 270-380 sized motors out there (or of any other brand), I would love to hear about it.

Thanks

A few will be coming out soon. I've been testing 3 240 size 4 pole motors. A 6000Kv is in my MLST, a 7500Kv is in my Recoil and I've tested the 9000Kv once in my 18R, but it was too fast so I went back to a 180 size 2 pole motor. They should have mounting for all the micro or mini mounting hole pattern.

Here is a video of the 7500Kv in action: http://www.youtube.com/watch?v=zXhGr...e=channel_page

Neu and Medusa make 28mm motors. The Ammo is also a good 28mm, and is a good motor. However, it may be the same as turnigy motors, which others say are good in the 28mm size. I'm still going on wit this discussion on another forum..

The Neu and Medusa 28mm motors will kill the wraith, mamba, dynamite, and most if not all the other 18th scale motors out there. I don't know of lehners motors, but they are atbout at par with medusa iirc. Medusa is the best cost/performance ratio..

The 28mm motors are a tad too big for the RC18s, I tried my Neu 11xx and it didn't go too well. I actually have a 28mm in my other Recoil and will take some pictures tomorrow to show you guys the size differance.

I'd say thats not even close. The Lehner is definitely going to out perform a Medusa. The quality of Lehners is very high. People would still be running the 19 series if you could get them...Neu is right up there, but some prefer the Lehner over the Neu...

I have two Lehners and both are of outstanding quality. Too bad they are no longer offered in the US (by a reputable seller). I will not buy from Fine Designs. Period. I have a project coming up where I need something bigger and badder than a 1940/7 (what I have now) and was going to do a 1950 or 22xx motor from Lehner, but have decided to get a Neu 1521 because I can buy the Neu through Mike.

However, if you run across a Lehner (that seems to be in good condition), it may be worth swiping up. They are very nice motors.

But for now, I think your best bet would be a Neu or Medusa.

Edit: Now there are two more posts that made it before me, I'd like to add to them.

As Squee said, Lehners are of outstanding quality and some prefer them over the Neu. I am probably one of those people. If given the choice, I would take a Lehner but both are great motors. The Lehners are 2 pole motors and tend to do better when pushed into the high RPMs (easier on the controller as well). They also have less drag as well. I like having a neutral handling vehicle so minimal motor drag is important to me.

Good to know about Lehner and Neu.. That's an eye-opener to me. Nice to know...

I remember seeing quite a few people run Neu's in their rc18. It might take a little modding or an aftermarket mount I guess.. I have had a Neu in my old recoil and my vendetta st. The 1107 I had in my detta was best.. holy crap... 8500kv custom wind on 2s. I had to trim the chassis a little and the motor almost touched the servo.... insaine...

Heres pics of the detta and recoil

Same setup in both in the pics, but I had a 1105/1....5y? in the recoil with a cheap ass suppo 40a esc. It worked, and worked great. Kind of funny having a $10 esc powering your $100 dollar motor in a mini.

and hey, lookig through these old pics I might as well post up a picture of this great looking guy. (or at least thats what they say..)

Usually its the other way around... :neutral:

But either way, I have a 300 dollar motor in my G2R and a 260 dollar motor in my CRT.5 and both were at one point powered by Mamba Max ESCs. The G2R now has a Monster Maxx, but even so. That is only like 25 dollars more...

So having a motor cost way more than an ESC isn't unheard of.

I presently run a Hyperion 5000kv long can yc-22, Mamba Micro Pro and a FP 3s 1500 pack in a RC18 set up is fast and doesnt get too hot

Just a side note to everyone wanting to run 380-400 motors in their minis, I suggest getting the 1/10th sidewinder over the mamba micro pro, especially if the motor is a Medusa or Neu. They draw a lot of amps and people have fried the old mamba 25s and run the 1/18th sidewinders damn hot on 2s lipo with a Neu.

The MMP is a sidewinder with a heatsink, which is good, but it might run a little hot with a Neu. The 1/10th sidewinder isn't that much more expensice ($10 iirc) and it runs ice cold. If you can fit it under the body, I HIGHLY recommend it.

Not only does the 1/10th sidewinder run cool in minis, but you can use it in a 2wd 10th scale if you ever get the itch too!

I also run the 6800 in the rc18...... It runs pretty hot though, and I cannot find a gear low enough. I want to step up to 3s soon, but with the high temps I am getting on 6c, I don't want to even push it. I did however hear great things about this motor. It is 4200KV, with a built in heat sink, and from what I hear, people cannot get it to overheat....

the Mamba motors do run hot, my fav setup is 3s and around 5000kv...the Neus 1107 are great but priced @ $100 a bit much for a 1/18th scale. The Hyperion motor I have I bought for $50.....my guess with the cheap motor from Hobbycity is it wont last long...but you never know and its only $19

I keept getting my Mamba 25 really hot and it finally fried, I now have a MMP and it runs pretty cool compared to the 25. The MMP is an improvement over the 1/18th scale Sidewinder

You guys will get twice the power with a neu over those hot mamba motors. There's a turnigy 28mm 3900 motor that will blow the mamba motors away. I know a couple people that use it and they haven't had any problems with it. The medusa is cheaper then the neu, and with both motors at 28mm, the medusa puts up a hell of a challenge to the neu. At the 8th scale the neu has a 4mm advantage... I say get the medusa.

In a Recoil those 28mm fit, but still a little too big for them. There's no need to go that big in a RC18. The 180 size motors do tend to get hot, I've raced against people who uses them and some got so hot that they smelled like banaid due to the sticker almost melting off.

Wow, thanks for all the comments people, you are all so helpful here, I really appreciate it.

I was wondering how hacker and hyperion motors stack up against Lehner, Neu and Medusa. (And against mambas) It seems neu and medusa are kind of out because of size constraints, and Lehner is perhaps a little "too" perfect at $150 (although the 1020/15) looks like a perfect motor.)

The Hacker E30-L and Hyperion Y-22 appear to be perfect, but of course they are a lot cheaper so I imagine the quality is a lower.

Thanks for all the help and answering my boring questions that I'm sure you've all answered countless times before.

The Hyperions are nice. I used to have the YC-22-5000 in my MLST, but I've been testing my 6000Kv in it. The problem I have with the micro motors currently available is the shaft size. I've broken my fair share of shaft and this is the reason my motors will have standard 1/8" (3.17mm) shafts.

Little video for you guys:

I made a mistake and should've said shorter then the 180 size 20mm diemeter motor.

Thanks for the vid, that was pretty informative. And nice 18R setup.

I've got a Wraith7k in my 18T which I THINK is the same size as a Feigao 280S motor. So: 24mm diameter and 35mm length. I think it's dying though because it's a bit rough to spin by hand.

I think the 180 are 20mm and the 280 are 28mm. The one thing I hate s the shaft size. My motor is nice cause I know pinions will be in stock and available in many teeth count to suit any application.

I run the Mamba 25... that is why I am hesitant to step up to a bigger motor, I'm afraid it will only cost more money by having to replace the 25.. Just curious, if my Mamba 25 happened to fry, and I happened to send it in to Castle for a replacement...would I get a MMP back? I don't think they still stock the mamba 25's. As far as that hobby city one I linked, it looks pretty good. My friend uses it. Geared 10/60 on 3s, he said it runs low 100's with about 30-40 minute runtimes. On a Rhino 1050 30C pack... Looks like a pretty good setup, I think i might go for that one. For $15, I don't really care if it fries.

They would probably send you an old re-done mamba 25 or an 18th scale sidewinder.

I think actually the 280 is 22mm, the 370 is 24mm and the 380 is 28mm. The original 18t came with an upgrade "super 370" that I measured just a second ago and it was 24mm.

Anyway, thanks for the video lutach! Very informative. I'm thinking of getting an exotek tek18, which it looks like you have. Does that long Hyperion can fit in there?

And do you have any more information or a link about your motors? Will you be selling them? I really like the look of them, are you going to make different can lengths? And what about pricing?

Thanks

I'm really not sure how the number things works out to be honest. The Exotek chassis is nice. I don't know if the long Hyperion fits it though. I don't have info on my motors yet, but when I do have them here, I'll be sending the 3 versions so Mike can test them out and hopefully sell them to you guys. The 6000 and 7500Kv are a bit longer then the 9000Kv motor. They will not look like that though. They'll have mounting holes for all the minis or micros (Don't know the difference) on the market and will be sealed. The color will be different as well.

+1 on the Hyperion, nice motor.
