LRP SXX StockSpec V2 ESC
#766
Sorry Bigz,
I only just seen this, I am running 17.5 with an FDR of 5.5, as for the ESC, i only know I am running the second highest boost setting and i think it's perfect.
I'm not to sure of the other settings
Speaking of cogging, my last run I think IT MAY have started doing this, but won't know till I run again. hopefully not. overall I am very pleased with it. speed, heat etc etc, although I am running the nosram monster heatsink and fan to help.

Ok, here goes. I encountered a really bizarre issue today. I am not sure what the cause is/was, but if anyone has seen anything like this please chime in. I ran my Stock Spec LRP in my 12th for the first time today. Previously I had only used it briefly in 17.5 Sedan. Both classes I run blinky, so 0-0 for the Modes 2/3.
I set the ESC up last night and cal-ed it to my radio(a decade old Futaba 3PJS converted to 2.4ghz). I programmed it to 1-0-0-3. The ESC was in blinky mode.
After about 4 battery packs thru the car today, during the middle of a run, my car takes off and stuffs itself into the board. I havent had a radio glitch like this since I used to run gas w/ FM radios. The car was stuck on a board with the front wheels locked to the left and the rears spinning in place. My Futaba started alarming and the screen displayed "B.U. Error". The radio had dumped its memory and it cleared all the models, settings, etc.
I had to reset the radio, all my end points, trims, etc. And I had to re-cal the LRP to the radio. I didn't mess with the programming at this point. In fact, I didnt even look at what it was nor notice if it was still blinking.
I went out for one last battery pack and the car was noticeably quicker than before and the lap times reflected this. When I pulled the car off the track, I noticed the speedo was no longer blinking. I checked the programming settings, and they were 0-1-0-3. As far as I can tell, the speedo went from 1-0-0-3 to 0-1-0-3.
Being an Electrical Engineer, I cant quite wrap my head around how this is possible. When the radio(and possibly the ESC?) took a dump earlier, I can understand the speedo reverting to the default settings. But I thought the LRP defaults were something like: 3-0-0-0 (ie: set up for 7.4v/2S lipos and blinky mode).
Can anyone fathom a reason how the ESC could have changed? It is almost as if one of the bits shifted positions... But that cant have happened, right?

sxx ss v2 dead within minutes
I must have the worst f'ing luck. My T4 has been down for 10 weeks now. I waited 5 weeks for the first v2. Which took a dump in 2 mins. Received my second v2 yesterday. Hooked it all up today. Same crap...died within 5 minutes this time. So i hooked up my Align Bec to the battery port on my Rx and everything works. So i assume the BEC in the esc is dead...again! So not kewl! I am done with the blue garbage and going back orange.

Anyone having any trouble getting their speedo to find neutral on their radio? I have the LRP sxx TC Spec v2 and I have to run a sub-trimmed brake of 32. If I don't the motor shuts off at about 85% throttle. When the throttle on the radio is released the red light comes on in the Speedo - like I am applying brake. I can pull it slighty and the blue light flashes. (running it in blinky) I have tried re-calibrating it several times with no luck. Could it be in the radio?
