yes you right upgrading software, when you say lots of time shift you mean crank that sucker up?

Rollout = (tire diameter * 3.1416) / ((spur / pinion) * internal gear ratio)


Iceman,
Yes "lots of timeshift" means crank it up (6 or 7). I never tested it myself though just quoted an earlier post...

62mm, but now if your talking about rubber tire racing, most make reference to FDR over rollout.

Yes i am running rubber tires. Once the track switches over to carpet onroad, i will try the suggested 3.9 FDR with turbo 1x and see from there.

Just checked the lap time and my buddy was 2/10ths of a sec quicker per lap over me.

jaco is 62 cs27 is 63 thats not a big difference so FDR does make sense, however we run VTEC 30R or something which is like 65mm. thats a big difference we talk about (enough to burn a motor). They use rollout on foams because the diameter constantly changes but if we compare gearing in this thread, rollout is still much better because of the differences in rubber tire diameters.

Ian tried a RB-S last night and was impressed by the power compared to his LRP TC.....he picked up 3 tenths right away and the motor temp was only 130f.
Me thinks there is more potential in the SC other than maxing the settings, more testing will tell.

Paul, I spoke to Les D late yesterday. Apparently he smoked the RB50 with the firmware upgrade.
This didn't surprise me ,as he tends to be little heavy on rollout with all his escs.I guess he took it too far this time ?

I will try mine , but only with a 21.5 or 17.5. I will be sure to gear it way down. With the SPX + 21.5 on the current Windsor layout, I got down to 45mm approx . rollout. The previous layout I ran around the 52mm mark, so this is a decent step.
Not sure if it's the layout,my aggressive driving or the sheer amount of grip available (all 3 perhaps?) , but people need to be careful witgh ANY advancing esc.

Regards,

Michael.

Lanzer, I am sure you will get it figured out......I like to crnk everything right up and work down from there, Maybe thats why I give the occasional smoke show

Guys if you crank up the time shift then you will be slow when you are feathering the throttle!! because when turbo is activated it seems to only have rip when you hit full throttle!! This is why i am prefering turbo1 and a bit of motor timing!! because the motor naturally wants to perform down low with motor timing and when you hit turbo it wants to rocket! now remember turbo on this speedy is different to every other it seems to ramp current to the motor which produces power and as a side effect seems to give more rpm as well or timing as most people refer. turbo 2 definately adds timing on top as well. but always remember time shift will not give you more timing with turbo switched on. now i have had no success with timing on turbo 2 but i had a test firmware from original prototype which i now have version b so will test a bit more and let you know!!
