Default LRP SPX Brushless Competition StockSpec ESC

Guys,

I run in 10.5 BL and was considering the LRP Sphere TC spec..... then saw this "stock spec version" ... interesting.

http://www.lrp.cc/en/products/electr...egler/details/

Has has anyone tried this stock spec ESC in 10.5 ? .... how does it go compared to the TC spec ...

Cheers

Alan

Looks and sounds like the TC spec without the fan or heat sink. Also looks like it has the same profiles as the TC. 1-4 for mod and 5-8 for stock. I would prob say a cheaper version. I guess it would go ok with a 10.5. Might have to watch the heat a bit. I don't know what the LRP brusless heat up like without a HS and fan on 10.5. I have always run a TC spec in that class.

I recently got an SPX Stock Spec and it does come with a heatsink, but no fan. I will be trying it soon, but I have moved from a GTB so I can't compare it to a Sphere.

Get yourself the Spx bullet reverse. It only has 4 profiles instead of 8 but comes with the fan and heatsink. Ive been running it with some 19t brushed and a LRP stock spec 10.5 and it has no problems keeping up with anyone. My driving on the other hand causes me to lose plenty of time around the track. But straight line speed and punch, I can't fault it.

Thanks Dadaman,

Yes I saw that both ESC's had 4 profiles for stock, also noticed in the stock spec manual that stock profiles have a higher values to describe "aggressiveness" than the TC spec. I can only assume these profiles may have more timing than TC spec ?? and hence more useful for 21 & 17.5T ..... perhaps too high for 10.5T.

If you you mind me asking ... what profile have you been using on the TC Spec for 10.5T..... you can PM if you prefer.

Cheers Alan

Yes I run an LRP Stock Spec 10.5. I ran it for the first time yesterday and it feels very different from my Novak GTB and Novak SS10.5, a lot more power out of the corners. Regarding heat, yesterday was a very warm day and I ran it for about 8 minutes in one run, and the ESC did not feel hot at all, only slightly warm. I ran the supplied heatsink but no fan, and no fan on the motor either.

The SPX's spec profiles yield significant rpm gains when compared with any of the TC spec profiles, so no it's not the same and not a lower cost version. Reports from snowbirds are saying profile 7 is the pick, and the advancement of timing make the car feel like it has a 2nd gear when going down the straights. I've also read the difference between the SPX and the TC spec is .3 of a second around a small track, but I'll let you know when mine arrives this week
