Can anyone recomend gearing for my TC5 with a 13.5 with an SPX on power mode 8?
Thanks in advance
Thanks in advance

Sorry wasn't too specific on that. It's a novak 13.5 with a 13mm rotor never changed the timing on the motor itself.

Some comparative dyno runs.
LRP SPX Stock Spec ESC
LRP X11 10.5t (ceramic bearings, extra cooling front plate)
SMC 5000mAh 28c
The current curves are very interesting (keep in mind the current reading on the Sentry is clamping above ~110A). You can clearly see the punch levels, the profile 1,2,3,4 increase in punch and it looks like (1,2,3) & (4,5,6) & (7,8) have similar timing profiles. You can also see the new Stock Spec profiles 5,6,7,8 increasing in punch, with 5,6 having a similar timing profile as profile 4 and profile 7&8 having large amounts of timing past the power peak. Any wonder you need to be careful on 7&8 with the motor pulling 30A at almost no load.
You can hopefully see why gearing down is good thing on profile 7 & 8.

Now that is some good testing! Thank you.

Well done gameover - the game's over now!!

so from what i make out from that graph is profile 6 would be a much safer
profile...i havnt run my spx yet on track but is there much in it between say profile 6-8
or is profile 8 the one to be on but just gear down 3 teeth?

I think the reason for gearing down is to not overheat the motor.
Well done GameOver. I salute you.
