Everyone I know who uses a Tekin tends to run 50 timing (max'd out) and around 5-10 turbo when running 13.5's
We used to run 40 on the timing when using 10.5's

Might be worth trying to run more on the ESC and less on the motor and see if the torque increases.

Sorry... offtopic. Is that Gate's X in your Av?

You follow TA in the US?

Technically no, it's a 9. Yes, but only every so often, when nothing else is on.

Thought I'd make my question clearer, for this setup how much motor timing was used?

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

Tried gearing from, 7.60 to 7.98 tonight with motor timing at 30deg
The following is my final (I was car 2, dark blue with pink looking front end using 7.98 FDR)
It was coming off around 61degC with only a small passive heatsink, no fan.

For once I was as quick as the turbo esc cars down the straight. But my drivng wasn't good enough for the A Final (Newbury only run 8 car finals)

for blinky racing you are going need blue rotor

or green.

Skiddins

We don't do blinky racing so not a problem

Changing the rotor would also stop it being legal at our nationals

red blue and green were sent to Paul at the same time as motor so should be legal but i am waiting for email to confirm this and i have spoke to Andy at rc explorer uk as well and he is a waiting same e mail

Skiddins

Ok, so whats the difference between the rotors?
I believe the standard item is 1300gauss (I did measure it but forgot to write it down

blue is the torque rotor factory advise to run in blinky classes

Fred Hubbard

Blue is a 12.3mm Torque and Green is a 12.5mm High Torque. Running the green yields more bottom end than the blue, runs cooler and you can gear up about 1 tooth from the blue and/or run a bit more timing.

Has anyone found the melting point yet on these motors? What temps have you seen and still managed to not roast the motor?

With about all motors if you get it to 190-200 it might smoke. I have had mine hotter than that without smoking but I wouldnt try it.

160-170 is what I would consider a safe operating temp. Anything over that might be ok but with all motors anything over that is pushing it.



To whoever asked I would run around 30-35 timing in boosted 17.5 Touring.

I am running the stock rotor. What changes in timing should I consider? I have never really messed with timing much before. But this is the Nats, time to man up.

Did some more running today at a larger indoor track.
Same venue but not this layout. You get the idea;

From my notes;
FDR 7.98 Motor timing 27deg, felt good, temps 50degC
FDR 7.98 Motor timing 30deg, felt good, temps 61degC
FDR 7.98 Motor timing 32deg, felt good, temps 71degC
The more timing, the faster the car felt down the straight but brakes became a bit weaker at high speed. Car felt fast out of corners.
