Hi Skiddins,
motor timing was 35deg, motor came off at 50deg.
Speedo is a Tekin RS Pro, firmware is 212.
Sensored
Timing advance 40
Timing boost 49
Turbo boost 13
Turbo delay 0.12
Start RPM 2721
End RPM 10001
2.0 ramp rate
Min throttle 10

9.61 FDR sounds like extremely low gearing.
Was anything taller tried, and what was the result?
I will post my test settings for Aldershot later.

Hi Skiddins,
short answer is: i don't know, I copied Ians settings off his laptop. Maybe someone else can provide this Tekin info.
Yes it is very low, but remember this was an indoor track(Stafford).
We tried higher gearing but the motor seemed lifeless. With the standard(BRCA) rotor we think it is a revvy motor.
We did try higher gearing but the motor had no lift off the corners. We intend to try one tooth less pinion on Thursday.

From my notes;
Aldershot,
3000rpm, 45mid, 9000, 50top, 200 delay
FDR 5.70 Motor timing 20deg, bit sluggish, temps circa 55degC
FDR 5.70 Motor timing 25deg more lively, temps circa 65degC
FDR 5.50 Motor timing 27deg still lively, temps 71degC
3000rpm, 42mid, 9000, 47top, 200 delay (Fastest Laps were with this setup)
FDR 5.50 Motor timing 27deg still lively, temps 61degC
FDR 5.16 Motor timing 27deg felt sluggish, temps 71degC
3000rpm, 40mid, 9000, 45top, 200 delay
FDR 5.49 Motor timing 27deg felt OK, but laptimes were down very slightly, temps 65degC
Try FDR around 6, with 20deg motor timing and 50-55 timing on ESC.
Remember, the BD uses 'true' timing for it's figures whereas I believe the Tekin isn't the same, they certainly aren't like for like.
I will try gearing down this weekend at West London and see what happens.

P.S. out of interest, was his motor 'screaming' or was it quite quiet when going round?

To give you some idea I was running 5.16 to 5.70 at Aldershot (Black Diamond ESC) which has a 50m straight and was fiddling with motor and ESC timing.

Here are some settings to start. These are form IIC and Snowbirds with a Tekin ESC.
17.5 no boost tc
35 degress of timing
Blue rotor 3.7 - 3.8 fdr
Red rotor 3.9 - 4.0 Fdr
This is for a track snowbirds size
Blinky 17.5 12th scale
red rotor
40 degrees of timing
95-100mm rollout
This all depends on how good your car is. The better the car the higher you can roll it out.
17.5 Boosted TC
50 boost
15 turbo
5000 -14000 rpm
.1 delay
10 min throttle
10 min brake
2 ramp
geared around 5.5
Red rotor
12th scale 13.5 boost
Red Rotor 35 degrees timing
45 boost
5 turbo
8500 end rpm
1600 ish start
.15 delay
10 min throttle
10 min brake
2 ramp
70mm ish rollout depends on track layout and size

Hi Skiddins,
Tried one pinion lower (16) at Stafford tonight. Ian said it was better on the short straights. Also tried a 15, gutless. Also tried an 18, seemed overgeared on same speedo settings.
Also tried the thin topdeck in the last round, Ian reckoned it gives more 'in corner' steering on a 2012.

If I'm lucky I might get some more testing done tomorrow night at Newbury;

P.S. don't know if I have enough spurs and pinions to get that low.
If I do get there I will be starting at 7.60FDR with 26deg on the can.

Guys, could do with a little advice, even though I run these in off road.
Basically I am running in a 2wd buggy and need to kill a bit of the lower end torque. The timing is at 20 degrees (it's a 7.5 motor). Temps wise it doesn't get unreasonably hot currently. I don't have a "boost" esc (sxx v1).
My question is: could I sensibly take the timing up to 30-35 degrees in this setup to try and dampen the bottom end a bit? How steep is the temp ramp when you increase timing on these?
