LRP esc´s: SXX TC vs. SXX Competition

[muratti]

I read on the LRP homepage that for 4WD Offroad you should go for a SXX TC esc (which i did) and for 2WD you should take the SXX Competition. The SXX Competition hasn´t got an aluminium air cooling unit as the TC has so i am wondering why it should be better for 2WD Offroad as the TC??? Is it only because of the height? Have 2WD buggies generally less space in height for the esc? The SXX Competiton has no cooling at all and i am wondering if it doens´t get too hot...Please somebody help me
Maybe someone of you has the SXX Comp. and can say somethign about it...

I've got the comp sxx in my b4 and it works perfectly without getting hot. It got too hot in my 4wd (Durango) but the TC works perfectly in that car.

Thanks for letting me know. Was the reason for you to get the Comp. the height in the b4 or did you buy it because of the commendation of LRP for the 2WD cars? Have you ever checked the temperature exactly? I would be interested in how hot it got in your b4 when racing hard?

I have a SXX TC in my B44 and SXX Comp in my X6. Why both types? - I didn't need the extra oomph that the TC will take for my 2WD so I decided to buy the cheaper version.

Both work superbly and I've never had the temp check go above 2 flashes (out of 10 max) on either of them. I also run the TC without a fan and it's fine right down to 5.5T.

Mind you, I'm not one of the fastest drivers around

Thanks, this helps a lot. I think i will wait until i have my TRF201 and buy the esc afterwards. If i have enough space i will buy the SXX TC, if space is tight i will get the Comp.
Maybe for interest of somebody: I talked to LRP Germany and they told me that the electronics are completely the same on both types, it´s only the height because of the missing aluminium cooling armature why there are 2 types.

One thing is different - the TC has 11WG motor/battery wires compared to the Comp which has 12WG. It allows more amps to be pushed through at lower resistance, but really only of any interest to the TC guys.

When I contacted Associated, the US distributer of LRP, they said to run the ssx competition.....what the F@(%!!!! the left had doesn't know what the right is doing

Are you getting problems with your ESC overheating?

[muratti]

Just to let you guys updated: I raced my DB01R on my track yesterday: much grip in comparison to all previous runs because it was perfectly wet. Had about 85 Degrees Celsius after 10-12 minutes of running with a 21t pinion. So absolutely no difference than to the run with 18t. What do you guys think? Should i be trying the 23t too ( then i would be as near as possible to LRP´s commendation: 8,0:1 and with 23t i have 8,111:1)?

@TONY: what heatsink with cooling fan have you mounted on your X12? I think it would be a perfect idea to get that too? Maybe a link?

Generally it says brushless shouldn´t go up higher than 77 degrees. So as we all know now that the X12´s are always getting higher than other i wonder if this is of any disadvantage for the motor? Will the durability be much shorter when running hot or does it have no influence? I have no probely with a 85 degree motor as long as i don´t have it much shorter than other motors because of this...

I tend to use the Ansmann http://www.jespares.com/electric-mod...tegory_id=1265- cheap (Billlig) but they do the job. You can buy the official LRP heatsink and fan at 6 times the price.

Thanks Tony! Do you speak German?
