Losi Xcelorin and LRP 5300 Lipo in Cat SX

[Mike Hudson]

No cells have been made legal for the 09 season for any brca events yet!
The official EB list of legal lipo cells for 09 isn't out till late february!
The trackpower cells arn't factory sealed aswell at current so will be illegal until they bring out new factory sealed lipos!

Nice one. Thanks for that. I'll wait till the list appears until I buy more packs then. I'll use the lrp(modded) at our club until then. If only the lrp was flat! Thanks for the input. I'd have looked a tool turning up with those packs at the regionals.

Ok but they were legal in 08. Are they really likely to rescind that?

Now I know why people are getting so worked up on the batteries threads I've been ignoring lol

Well some regions allowed them, but they wern't legal for nationals. I hope we get something soon, im down to two working packs.

I would like to think that the EB will consider the heatshrink over the packs to be classed as the factory seal. If this is removed then fair enough, the seal has been broken.

If you look on any packaging, the seal is usually a bit of plastic and a sticker.

Im pretty sure is doesn't say factory glued

[Cassp0nk]

wonder if trakpower would let people send them back to base for inspection+seal sticker.

What exactly is the reasoning behind this rule?

[Mike Hudson]

to ensure no-one has tampered with the lipo cells inside, it's all about the health and safety

Damn, and there I was about to tear it down and change the lithium formulation with some added kryptonite. Now i'll never win

Wires to the ESC are nice and short from the motor. This orientation means the LEDs on ESC are on the outside and easy to see.



The vertical outlet of the Corally works better with the LRP LiPo. It keeps the wires well away from the belts.



But you have to be very careful how you place the front as the bumps on the LiPo only have approx 1.5mm per side clearance of the 2 front pulleys.

You can also see the velcro I cut to shape on the LiPo and strap. I also used the locators to make sure the LiPo didn't slide around and hit the pulleys.

Forgot to say thanks for the pics. Where are the LED status lights on the xcelorin as I don't want to cut cables and realise I've arranged it so I can't see them! The manual cunningly doesn't have a diagram showing where they are! In fact it doesn't even say where the button to change modes is but I'm guessing its the microswitch on the main power switch?

Hoping to do my wiring tomorrow if I get a moment.

[JackWood]

I know!! I spent ages looking for the LEDs before I had it wired up. It was pure fluke that I had the ESC the right way around to see them! The manual is good, but missing such a basic thing like that is s bit stupid.

In the top photo the LEDs are on the bottom side of the ESC, facing the wall of the bottom tray. Really this is the only way you can orientate the ESC and be able to see the LEDs. And yes, the push button is the one on the switch. You will need to be able to see the LEDs for programming.

After my first "incident" with the Xcelorin, with this second unit I assembled the whole thing and ran it for 20+ minutes in the carpark at work to make sure everything was running fine, and only then started tidying up the wires. Did the battery harness first, then tested it again. And finally shortened the motor wires and tested again. All good this time apart from the lack of reverse with the 010128 software (010125 works fine).

The only difference you might want to make to mine would be to come 90deg out of the Corally connectors out of your Trakpower LiPo. On the LRP the terminal sockets are recessed, so not possible to come out 90deg, hence the out-top way I soldered to the Corally plugs.

Sorry guys I went to bed early last night, but I think it has all been covered.

• You are not allowed to modify the hard case.
• NOTHING is legal yet.
• Heatshrink is not classed as factory sealed - it can be removed without tools (unless you include Lee as a tool - then a tool can remove it)
• The factory seal has to mean the case is damaged if it is removed.
• This rule is to stop tools fiddling with the lipo internals.

Yeah I wasn't sure about 90 deg or not. Your way does a nice job of keeping one of the wires out the belt. Maybe one done each way is best. Think I'll just wire it up with long leads to start with then modify as you did.

Shame about your reverse problem, did you manage to sent the full reset to the ESC after upgrading as the data format for its settings appears to have changed so they need blanking and doing from scratch. If you didn't, it would also explain why it works ok when you downgrade as your settings would then be in the right format.

[JackWood]

What? Say again?

How do you send a "full reset" to the ESC after upgrading?

Funny thing is, today I was massing around in my kids nursery playground and even with the 125 software, reverse wasn't working. Something strange is going on, and I'm not sure what.

Maybe I need to try another transmitter.

On the commands drop down menu, click 'reset to factory defaults' once you've upgraded.

[JackWood]

Oh yes, of course. I followed all the instructions on the PDF and in the manual, to the letter.

Everything else works fine, just there was no reverse with 128, and now for some reason the reverse with the 125 firmware has stopped working.

[Cassp0nk]

sounds like a duff unit

[Cassp0nk]

Well that was famous last words. Mine won't reverse either. Leaning towards just returning the unit for a refund as was warned off losi and if their firmware is still shit I've not got time or inclination to be the guinea pig.

[JackWood]

I know what you mean. I wish I had sprnt the bit extra on a Speed Passion system or Notvak.
and see wha
I'll have a word with Marc and see what he suggests.

Late Feb??

Where is that from, if it's late Feb it'll be longer than I thought before I can run the Cat! Assuming it's then possible to actually get anything on the list, I bet there will he quite a rush of buyers!
