Reto, do I need to install the heatsink and the fan when running 4.5T in a touring car?

For 7.5T 2wd buggy with profile 1-4, will SPX Stock Spec get anywhere close to temp cut during summer time with high air temperature?

Yes for the TC, no matter if used with 5- or 6-cells with 4.5t, you'll need heatsink and most likely fan as well.

For your OffRoad combination you won't need a heatsink.

hi guys, hopefully you can help me make my mind up..

i run lrp vector x11 10.5 and am looking for a new esc...

im looking at the SXX and the SPX competition

how close are the two? is the sxx the better speedo as latest out?

which one do i buy? is the SPX far better suited for 10.5 profile 7-8
or does the SXX do the same job in profile 9-10

please help as i really want to buy but dont want to buy the wrong one

Anyone have an idea on gearing for a rubber sedan 17.5 with an SPX in profiles 6-7-and 8? This is a Novak 17.5 and I was running 3.50-3.75 with a GTB. Track size is 120' x 80'

For 10.5 get the SPX Competition and no the higher profiles are not the same.

Hi Reto,

The SXX is finally out, but in UK only!

http://demonpowerproducts.co.uk/prod...oducts_id=4350

Can you please give us the profile comparison between Sphere TC, SXX Competition and SXX TC?

For 13.5T and 17.5T off road truck and 2wd buggy, would you run SXX TC, SXX Competition or SPX Stock Spec, and which profile would you choose?

Hi Jon,

Do you know to initially hold them down for at least 3 seconds to activate their respective modes?

If so, describe in detail what you are doing...

No, the SPX is the better ESC for 'Stock' motors, the SXX, although it has better voltage drop characteristics etc. is mainly aimed at Mod drivers.

If the other ESC's by LRP are anything to go by (the descriptions of which are in this thread a page or two back) the only difference between the SXX and SXX TC is the heatsink!

Puuh, too many questions for me already...
Should re-name that thread in "Ask LRP" or something as it's not just SPX StockSpec related anymore.
Will try to answer the questions about SXX vs. SPX vs. SphereComp.

80710 vs. 80700/80750:
- explained in my post #101 in this thread I guess.

80900 vs. 80950 (the two SXX versions):
same internal hardware, difference is only heatsink/fan.
So 80900 is lighter, lower profile and doesn't come with a fan.

80900/80950 stock profiles:
SXX doesn't have "extreme stock profiles".
Nevertheless the SXX's profiles 9+10 will be suited well for stock, but I would suggest #80710 for hardcore stock racers as it has more aggressive timing.

Profile comparison between 80900/80950 (SXX) and 80700/80750 (Sphere):
We do have a nice chart in our SXX manual, which does explain curve, limiter and timing for easier understanding. See attachment under chapter 7. "Mode Programming".

SXX's steps for power profiles are finer then Sphere's and also it starts at slightly lower power in profile 1. What comes now is not 100% precise, as many small things have changed, but give you a good start and help to understand the SXX if you already use a Sphere:

SXX #1 -> slightly lower power then Sphere #1, but close
SXX #2 -> inbetween Sphere's profiles #1 and #2
SXX #3 -> similar to Sphere #2
SXX #4 -> similar to Sphere #3
SXX #5 -> inbetween Sphere's profiles #3 and #4 (that was quite a big step)
SXX #6 -> similar to Sphere #4
SXX #7 -> similar to Sphere #5
SXX #8 -> similar to Sphere #6
SXX #9 -> similar to Sphere #7
SXX #10 -> similar to Sphere #8

As said before, none of the profiles is 100% but this is the closest I can explain it and got all the teamdrivers understanding it as well...
