Hacker C50 Maxx
 

Theirs a new one at my LHS that is being sold for $50. I plan to go and pick it up this weekend sometime. I plan to run it on 5s and not 4s which is the limit. I think it'll be fine.

How many rpm is it turning on 5s?

What is the name of the shop - Will they ship - Just kidding but that is a steal - get down there quick... Just have to watch the shaft as I recall it is 1/8th... Rgds

Kv on the standard "C50 Maxx" is 3033

I would not recommend 5s unless it's in a (relatively) light vehicle with suitable gearing for the +50000rpm it will spin. Mine ran hot in my racing emaxx with 12 cell nimh, back in the day. Around the 180-190 range after a good 5 min run in the summer.

I'm interested though to see how it does for you.

No offense, i understand what u get for the price, but why not just get the motor with the right specs.. its not worth 50 bux if its blown up

I'd assume it's going into his Cen Matrix truggy. From what he has told me, a velineon motor does not even have heat problems in that thing, so I'd assume it's pretty dang light.

The c50 maxx is a good 4s motor, not sure if I would try 5s, but at 50 bucks it is not too expensive. Do not use this motor without a slipper, as the 1/8" shaft will break. I broke one shaft in my hyper7. The shafts are hardened, and quite brittle, I even tried to weld another piece back on and have it machined, but that did not work either. Tekno sells a 5mm upgrade shaft for $75, that plus the $50 makes $125, still a good deal for that motor.

How many C50s does your LHS have?

Only one lutach, :) I know I could not beleive what he wants for it either. I plan to go pick it up this weekend. Ill let you guys know. I might run it in the metrix but im doubting it. Linc Ill take a look into that upgrade. Still sounds like a great deal!

Hey linc, could you give me a link to the 5mm upgraded. I cant seem to find it...

You lucky dog you :lol:. Great price on it. I think Kyle from Hacker Brushless sells the 5mm rotor assembly for $50 (Not sure, but I can't find the e-mail he sent me).

I really want to know were you can get the 5mm upgrade. If I could get that I will run it on the matrix for sure.

Found the upgrade- http://www.impaktrc.com/product_info...osCsid=d5e22ae

The rotor looks tiny for the size of the motor...

How much do hackers run with the 5mm NIB?

It is $50 + $12 for shipping (Don't know why it's so high) send Kyle an e-mail kyle@hackerbrushless.com. I don't know if the price went up or down. That price was from 2007.

Thanks for the email addy lutach!

The c50 maxx uses a s can length rotor in a l length can. Basically gets higher rpm from using the smaller rotor. You could buy a l can rotor and put it in the hacker, which should give you around a 2000kv motor.

The windings appear to be a 13l, but the lighter, smaller rotor ups the kv rating.

Do you know what the l length rotors cost lutach?

I only asked for a price of the 5mm shafted rotor for the C50-maxx motor and that's what he gave. I did swap the rotor fro my 13L into the C50-maxx and they fit like a glove. So when you guys e-mail or call Kyle ask for the C50-L rotor and not the C50-maxx rotor.

When you swaped the l length shaft/rotor in what kv did you end up with? Was it similar to the 13l, they output wires look to be the same diameter.

I have a 13l, 14l, and an 8l, and the 8l has much thicker wires coming out of it.

Thanks a bunch lutach. Thats the first upgrade I plan to get for sure when I get the hacker.

Didn't run it yet :lol:. I'm not sure if I will. I might just put the rotor back in the 13L and do some surgery on my Mr. C MBX5T kit to make it fit. I'm also undecided if I should go with the C50-13L or the ION-X that sems to be a C50-13XL, but gray instead of purple (Barney drives me crazy, I :slap: any Barney I see). I was thinking of removing the purple from all my motors :lol:.

It's a must if you don't want to snap your shaft.

And snapping your shaft sounds very painful! :gasp:

Did lincpimp steal you username and password :rofl:. You guys crack me up :rofl:. Palm:rofl:ela Hand:rofl:erson:rofl::rofl:

One more question... Ive heard that the feigao L series rotors will fit into the hacker c50 motors. Is this true?

Even if it does, I wouldn't do it. The C50 rotors are wrapped with Kevlar and the magnet is different as well. Maybe that's why the Hacker C50s are more efficient.

Hmmmm... Good point! I will keep an eye on the hacker 5mm upgraded rotor as well.

Got an email reply, here it is:

James,



Yes we do sell a rotor that is 5mm in size for the C50 Maxx motor. The C50 L rotor will not work with the C50 Maxx motor for it has a special magnet length.



The 5MM rotor would be $75

Wow. I should reply to Kyle now and see if he still can do his $50 for the rotors :lol:. Good thing I save most of my e-mails :lol:. Might be because I was going to buy 2.

Worth a try...maybe he will give them to you for 50 each if you buy 2. I would buy one for 50 or so, see what he will do for you if you buy 3! Was the 50 quote for the stock replacement, or the 5mm version?

This is just an observation.. but a $50.00 motor which will require a $50.00 upgrade and will STILL be a very high kv wind if used.. Doesn't it make more sense to just opt for a Medusa Afterburner instead?

Yep, you are correct. The hacker c50 maxx are nice motors though, and look like none other. I am sure that the 1/8 shaft that comes out of that hacker will sell, hell I would buy ity for the right price!

I agree that Hacker C50's are nice. As well, I have a nice vintage Tamiya Avante with an original gold Tamiya 1200 battery and a Tamiya Dynotech 02H motor. The Tamiya Durga I just picked up with a MM5700 and 3s Zippy lipo cost a fraction of what the Avante is worth. I'm sure you know where I'm going with this..

Yep, you are basically saying that there are better options than the hacker, for the same price. I agree, but still like the hacker. I ran mine til the shaft broke in a hyper7 and the performace was great, and it ran cool. I now run a c50 8l on 4s in that buggy. Gearing is low, 11/46, but that buggy flies, and the equipment seems to be ok! Not a common setup, but works great for me.

The c50 line are very well made, I have a few and have had excellent power and service out of them. They are a bit overpriced new, especially compared to the medusa motors, which appear to be the perfect motor, cheap and powerful/effecient. I wish someone would directly compare them to a neu. I guess I could do that, just need to buy a 1512 1500kv motor to compare to the 36/60/1500 I have. The neu is twice the price, and i really do not see it performing twice as good in a buggy.

I'll send Kyle an e-mail tomorrow and I'll let you know what he says.

Sounds good, let me know. I was happy with the performance, even with the shorter magnet assy. It actually had a bit less torque than the L can I am using now, which helped the buggy stay stable. 75bucks is a bit steep, especially since the shafts are too brittle IMO.

Good news. Bought the motor hacker yesterday and I couldnt be happier. Very nice internal and external build. Never seen anything like it. Ill see if i can get some pics of it here soon.

It is a nice motor indeed. I'm still waiting for Kyle to get back to me with prices for the rotors.

Thanks again lutach. I doubt i'd be able to get anything for the stock 3.2mm rotor.

I have a couple C50 motors... one with a snapped shaft. I ran a Feigao rotor in it... and it ran fast and hot until I finally killed it. It wasn't worth spending $100 to fix it... but $50 sounds much better.

I would like to see how it would run on 3s in a light buggy. I think it's too hot for the 4s I was running. It was hella fast and ran hot with the Feigao rotor. I've been curious to see how a new Hacker rotor would compare to what I had in it.

My c50 maxx ran fine in my hyper 7 on 4s. I had to use a small pinion, 11t, to ge the speed near 40mph. It ran cool and had a nice balance of power and speed. Then I snapped the shaft. I now have a c50 8l in there and it has more torque, and runs slightly hotter. It definately pulls more amps, as the mm is heating up now, more than with the c50maxx motor. I would like to have the 5mm shaft and run it in the buggy, as the 8l is a bit too much on 4s. I also have a c50 6l that will go in the crt.5 on 3s.
