Everyone who requested PC-Software and Speed-Control Firmware has received it by email now.
I'm currently also checking Windows7 64Bit compatibility with engineers as this was a question sent to me by email!

All the files are now also available on our website finally, please following this link: http://www.lrp.cc/en/service/software-update/

Default binding problems

I have 2 SXX stock spec, one with the v4.4 and one with the v4.3
Im using the v4.4 in my WGT with Futaba 3VCS tranny but with spektrum module and receiver fitted. Going great no problem.

When trying to bind the V4.3 with same tranny set up etc.No go kept losing bind. Then tried to set up with the new sanwa gear and no problem runs good.
Is there a compatibility problem with Spektrum dms -dsm ???

Silly question:

I would like to wire a cooling fan directly to B+ and B- leads, easiest spot looks to be on the underside (near sensor plug).

Is the solder on this the 'normal' kind or is it that silver solder which requires high temp to work with?

I also want to shorten the ESC wire and power wires. Any way those are replaceable if I want to lengthen them for use in another application in the future?

Thanks

Default solder

Ive changed all the wire on my new controllers for 16gauge CRC very flexible.I resoldered with Silver solder as i find this type to be the best flows very easily and makes for a good strong join

Default software upgrade 4.4

As a complete computer numpty, i found the down load and up grade very simple. Both my Escs now up graded so off to the track for testing the 1/12th with the x12 and 1s rotor.

Thanks in advance.

I love my v2, truly I do. But I have to be honest, the way you solder wires to this ESC is dreadful. Having done the world tour with other ESC's the past 1.5 years, I can say with certainty that solder posts are absolutely, without question the way to go.

Also, it's kind of a bummer that my 1 month old, $250 ESC already has the plastic chipping off the case. Whatever process you guys are using to coat the plastic with that metallic blue stuff, it's not great.

Sorry. Can we still be friends?

Gaa you said it I haven't run LRP since the SPX but I've just picked up an SXX. While I consider myself decent with the soldering iron I still managed to nick the case slightly under the circuit board with the tip. NOOOOO!!!

P.s. I'm referring to a TC spec V1 but it's same-same

The only way I've been able to de-solder these things is with an "industrial" soldering iron.

Literally have the heat on it for 3 secs and it pulls through.

It's also the only way I've kept them clean.

We use thick copper boards, in order to minimse losses and get maximum performance, but that indeed results in the fact that power wires are a bit harder to solder if a "weak" soldering-station/-iron is used.

Also there is a reason why we don't use solder posts, which is the fact that solderposts increase losses, direct connection to the PCB like it is realised on the SXX is best for performance.

Out of curiosity, would you trade a little bit of performance for easier solderabilty (right word?)?

I guess that depends what you mean by "performance." If it affects the overall top speed, I'd be willing to sacrifice that, 'cause I'm not so sure I'd notice on the track. If it affects how smooth the throttle of the ESC feels, then no, I'd suffer with the current solution forever.

Really? Didnt think the little things like that were as big of a deal with lipo and brushless technology. I would like to see a back to back test. Same car, same driver- 1-sxx v2 without solder posts and a sxx v2 with solder posts. Im willing to bet that the difference is NOT noticeable.

BTW- (Burito)Your response sounded good though.
