lrp spx stock spec
#871
Thanks for your help! Im running SMC 5200 40C Packs so they should go pretty good. Thinking about getting some intellects though. I don't usually go by rollout so you wouldn't know how to convert it to FDR?

LRP SPX
Hello All,
I am new with SPX. Can someone tell me what the different profiles of the LRP SPX do ? How they work and what the result is on the motor (10.5). Or where can I find such info on the net ? All help is welcome. Thanks.
Tia.

The higher the speed profile, more punch more speed. Please check your gearing & best to have motor heat sink with fan.

we have a technical but flowing track with a 30m straight , and i run gearing of 105/37(trf416 with a final drive of 2.0556) on program 7
i added 2 teeth to the pinion to settle the car out of corners instead of going down a program because i still wanted the timing boost of program 7 , it works well for me
Hope this helps a little

As far as I know (new to electric though):
If only the motor is hot, it is undergeared. Put on a bigger pinion or smaller spur.
If the entire system is hot, it is overgeared. Put on a smaller pinion or bigger spur.
Please correct me if I am wrong. I am new to electric - just got told the above mentioned.

Dropped the ratio down to 5.6, car came off cooler (65 degreesC), quicker down the straight but lacked punch out of the corners. Went to up to 5.8, just as quick down the straight, had way more punch out of the corner, came off at 68degreesC.
Final run I went from setting 7 to 8, came off at 73degrees.
All in all, much better than it was before (90degrees C). Not running a fan. The brakes on the stock spec are immense, making loads of ground down the straight and on the brakes into the tight turn at the end. Shame the tyres have seen there best though.

if your gearing is correct on the straight you will see the car get like a second gear
i just altered the gearing to remove the agression from the motor on throttle out of slower corners
i believe the timing boost is only available in programs 7 and 8 but may be corrected
i find the car is more stable with this setting , i got the gearing spot on and then altered it by 2 teeth higher on the motor to tame it

Does the timing boost work for brushed motor?

i had the nosram matrix istc before and ran at 4.9 with a novak motor
i want to run on the highest profile 8 at a guesstimate what ratio would you guys suggest for this track ?? thanks

With my SPX on 8 and my Trinity Duo 13.5 set to the center timing, I run a 5.7 rollout on a similar track.
That was a nice race on youtube!
Cheers!
