Question about c-50
 

I'm running a normal c-50 in my maxx, however i've just bought a special limited edition c-50, which look's awesome.

The only down side of the motor i'm buying, it's got a broken spool(pinion snapped off). Now my original plan was to use the spool of my current c-50. But since i've always been slightly consurnd about the weak 3,2 mm shaft, are there any other spool's that will fit the c-50 but with a 5mm shaft?

Also does anyone happen to know the kv rating of the c-50's?

Thank's.

The kv was around 3000. If you got the one for the maxx they have. May be able to put a feigao shaft or somethign in it.

Depends on the wind(Kv is determined by the windings, not the magnet). Pretty sure a Feigao or Hacker shaft would fit right in, but there are some issues to this theory. The best for that motor would be a Hacker rotor(make sure proper clearance from shaft to windings), with a 5mm shaft. I say use your current motor's shaft and keep the pinion closer to the motor can when you mount it to avoid the potential for a broken shaft(most times, the shaft is broken due to high stress when the pinion is mounted way out on the end of the shaft-leverage will win!).

In this case the previous owner had run his gmaxx with a tight slipper and hit a car tire at full throttle, while during the crash still giving throttle. Since the motor didn't had a chance to get the power away, the shaft broke.

If you(Mike or anyone else) want's I can take measurement of the motor/ spool when I get it?

Did the shaft break, or did the rotor dislocate from the shaft?

If you look closely it broke on the point where the shaft was getting thinner.

the flat area?

Yep.

I have two of the C50 maxx motors. Ran them as a dual set-up until the one motor broke the shaft. Than ran the other motor as a single. It lasted about three packs before that motors shaft broke.
The shaft on these motors must be WEAK as there were a good number of people who broke shafts on these motors. A 5mm shaft would be a wise choice.
Thank you,

Actually(and I have to knock on a piece of wood really hard this time) this motor seem's to be holding up well. From full speed to spinning the tire's in reverse on a normal road. I really thought i'd hear something snap, including my stock tranny, but it didn't. Guess I was lucky.

So a 5 mm shaft it is. Which will fit?(if any)

im assuming a feigao, nemesis, wanderer L would fit.

Why not contact hacker usa about it? Not always the fastest I know but just don't tell them it's for an R/C Car (otherwise they scream bloody murder). I think they make 5mm shafts for the c50 cans, just not the maxx editions.

That should confirm that:) Hopefully those can's are the same dimension now

Doesn't the C50 Maxx use a 12s rotor? I've heard that it's just a 12s rotor in a larger can... Are my sources correct?

Thank's re-mix, when I get home from work this afternoon i'll measure up my c-50. Hope it will fit.

Heard/read that too Metalman.

Yay got my "special" c-50. What so special about this version you ask, have a look at this;

This will look allot better than that ugly purple one. And for only 36 euro's shipped, i'm not complaining.

Going to measure it up in a few minute's. Hope I can use the c-50s spool in this puppy.

I don't got the right measurement's on the c50s(like spool dia, length etc). I've send hacker usa an email, saying I use it in an airplane lol. Hope they respond.

Say the shaft broke in a crash :lol:.

Is or was the C50 avalible in different turns ?.

Yes they are hippie. They have different sizes to. Kind of like feigao motors.

Thank's

Got a reply back(actually 5 minute's after I send the email). Can't use the spool of the c-50s, since the spool of the c-50 maxx is unique for this type of motor.

I've asked if it's possible to custom order the spool without the thin part milled down, hope they can/ will do this. No reply as of yet, will let you know how this work's out.

I just measured the c-50 rotor, here's a picture. (note that the flat area on the left broke off)

If anyone can measure up a fiegao rotor(or any other rotor with 5 mm shaft), please share the measurement's with me.

No reply from hacker as of yet.

A feigao long is about 30mm in the magnet area and 19 width wise. I can take more if you like like over all and stuff.

Hmm with a bit of luck that will fit, else mayb a smaller fiegao rotor. Dunno how a longer magnet would affect it's performace. The inside dia of the winding's is 19.50 mm.

It almost looks like a basic xl motor armature. I don't have one handy. I should have saved the one I burned up.

Back on the first page, I suggested that the C50 Maxx motor uses a S size rotor, and Serum said that he heard of that too. So, you could try a S rotor from a Feigao.

I found that too when I asked Hacker a similar question.

I've got a C50 with a rotor that looks just like yours, I had a stripped spur gear that caused it. Not a good day ;)

anyways keep us posted if you find what works.

Anybody has some more measurement's?

Anybody?

You trying to match up one with the size you need. I don't have nothing but big motors handy. I would help if I could. Sorry sneek. The motor seems to be close to a 540 can size just have to get the right length.
