curious issue...
especially since i am almost ready to make a purchase of the x12 4.5T myself

dont want to jump the gun here..
but i'd be interested to know if there have been any other reports of the same problem and more on the metric bearing issue?

as for LRP dealing with your specific motor, i'd say its a safe bet they'll come to the party on a replacement for you

But actually there is no plans for StockSpec version of X12 yet anyway, X11 StockSpecs are still running strong.
LOL....11.5T is supposed to be equivalent (or so) to 23T brush. Asians used them to power our shavers

+1 to that. Looking forward to see more 11.5T motors manufacturers in the market rather than the usual SP and feigao based ones.

KoE - jeez, what do you shave with that shaver? oh, is it powered by lipo?

@billythekid: sorry to hear about the bearing failure on your motor, we didn't have such problems at the Worlds in Thailand were we ran in very extreme conditions so I would think this is a "one off" problem only.

From former experience with old motors, bearing failure can occur if:
1. motor wasn't cooled down entirely between runs.
2. far too high gear ratio.
3. too high power profile used.

So it would be good to know more details of your application.
I don't want to say you did something wrong, I just like to understand what could have caused it.

As for the repair, I'd suggest you speak to your hobbyshop and your countries LRP distributor. I'm unfortunately not of much help from here.

The bearing is not an "odd metric size" btw, it's a 4x10x4mm bearing which should be available from many companies.

Default LRP 5300 28c Lipo

Hi Reto,

I have a quick question regarding the LRP 5300 28c Lipo. I am considering purchasing several packs, but I need to ensure it can fit my Cyclone TC without major modification, such as grinding the aluminum motor mount, upper deck etc..

Can you please check with guys on your team or your tech?

I have called several hobby shops and no one seems to have any clear answer for me. I am looking at buying them this week, I would appreciate it if you can let me know soon.

Thanks in advance.

@billythekid
On the Cyclone TC you may have to take away some material on the lower side of the motor mount. Approx. 1-2mm, but only on the motor mount and only a small area. The topdeck clearance is fine.

Best regards,
Andy

i promise only a small thread hijack (i started it anyway so ner :P)..

Burito or MrC:

i have been wondering this for a while...

when i have purchased the LRP TC Spec ESC inside was a little slip of paper signed by either "Monika" or "Sabine" ... who are they? do they actually work for LRP or is that just some marketing guff throw into the package?

now for the non-hijack part...

with the x12 5.5T i have temped the motor at around 80 deg C when geared at 10.08 FDR on a short track (~100m)..

i am guessing thats normal going from other people's experiences.. but what realistically should be seeing?
can you give us some figures from the motor temps and FDRs for the guys than ran the x12s in TC at the recent Worlds?

-Mark

As for the gearing at the Worlds with the X12's:
- we ran 4.5t
- lowest timing setting (oooo), which seems to work best anywhere!
- gearing ~8.6:1
- powerprofile 3 on the speedo

Remember this was with 6 cells.

As for the temperatures, anything below 100C is fine!
The X12's does get fairly warm on the outside as it makes a lot of power and also transfers the heat well from the inside to the outside due to the clamped stack. But we have a magnet with a very high temperature grade, so until no solder starts melting there is no danger...

Those stickers are always indicating who packaged the product. Why are you asking? Wanna get married to one of them?

excellent, i was hoping that this was the case..

so would it be safe to say that the internal temperature could very well be less than the measured outside temp?

where would you recommend checking the temp on the outside?

it seems that some motors like the pinion end, others about 1/2 way and some at the endbell end...

haha maybe.. are they hot? pics?

honestly, i had noticed the different names and had my theories hehe..
you could collect them like trading cards :P
i know there are monika and sabine, but how many other names are possible to collect?

@mok: no secret what we ran at the Worlds...

The temperature is spread quite even on our housing, there is not much difference on were you check. I usually do on the upper housing (shorter half) close to the plastic to do it the same everytime and since it's usually the easiest place to measure in most cars.

@HarryN: glad to hear you do like the motor so much...

Thanks for all the info.
For 5.5T, with Lipo, medium-large track, with low traction, i use 7.8, and power profile 4, 70-75C, think i have a litle window for going up 1 tooth more (7.65) ?.

For the hi-jack part...
My prefer is Sabine, i have some stikers with her name, , but i have one stiker with the name "Manuela", i like, sound more latin like me

Greetings, Luis C.

Hi Andy,

I can add some washers under the U shape motor mount to raise it. If I raise the motor amount by 1 MM, and also remove the battery tray, would that be sufficient? I prefer not to grind the motor mount if possible.

By the way, how would the LRP 5300 28C compared with SMC 5200 40+C in terms of punch, average voltage and durability?

Thanks.
