I was using my SPX in mod this week at the IIC race. 5 minute runs, indoors, high traction, 2cell lipo, touring car, 6.5t motor. I had the ESC heatsink on for my own peace of mind, and it survived.

What profile were you running?

Profile 2 on my 6.5t, profile 8 on my 13.5t.

i find profile 7 is better for 13.5 , it is less agressive on the power out of corners

i am just as fast with profile 7 as i am with 8 but the motor temps are about 10 degrees C cooler

I need some clarification on the ability of this speedo.

I fully don't understand what the "power #x" actually means on the instruction sheet. I have read that 6 7 and 8 are the most advanced of the timing boosts, and I have also read that the SPX will increase your rpm no matter what profile you use.

Could someone explain to me exactly what the power setting does, and how much timing gain you get by changing each profile.

Thanks a ton.

Hi,
The last profiles of SXX TC give more timing to the motor...
Is SPX stock spec give more ??
Thx

I believe the high profiles on the SPX (profile 7 & 8) advance the timing on full throttle which gives you more rev's, these profiles are for 'Stock' motors, i.e. 13.5, 10.5, 17.5 etc, not Mod motors.
You have to lower you gear ratio to take advantage of these profiles otherwise you overheat the motor and speedo.
No-one knows exactly how much timing it adds, they won't tell us

The SXX is generally for mod motors, the SPX is for Stock classes.

The SXX does NOT have the timing profiles of the SPX, on the SPX the adnaved timing profiles are only on profile 7 & 8.

Advance timing is also available on profiles 5 and 6 just not as aggressive. There was a graph posted a few pages back i think showing the power curves. We had a guy who was running profile 6 at our recent states and he was keeping up just fine with all the other guys running profile 7 and 8 which was surprising to me. Good driver though...

Hi,

I think this is the thread for this question... Anyone run an LRP SPX (mode 6 or 7) and an Epic Duo 2 (17.5, 0 timing) brushless?

I'm looking for an FDR starting point for a TC5R on medium traction asphalt track. Any help would be very appreciated.

I was running a FDR of 3.89 with a Novak Havoc 17.5 system... but was told this FDR may be too low for the LRP/Duo2 and it might burn it up the motor.

Thanks!

I ran my Duo -1 at 4.2 in 17.5 2 weeks ago and nobody pulled me plus came off the track at around 145. Prob. a good place to start.

Thanks, Verndog!!!!

No problem...forgot to add, that was using profile 7 also.

I also started with a 4.2 and profile 7 with my Speedpassion 17.5. I ended up at 4.09 so I was close where I started.

thanks again guys!

I've got gears to run a 4.11 on a TC5 and 4.16 on a Cyclone... I'll check temps out with after 3 minutes into run on profile 7... hopefully it will be below 160. If not, I'll adjust to profile 6 or move up on the FDR.

Much appreciation!
