ESC modes and gear ratios
Good day to all.
Please I beg your indulgence as I ask seemingly endless questions.
Here's the setup:
Reventorn R 13.5 combo
Now in blinky mode, I always hear/read that a 4.0:1 ratio is ideal to be competitive.
Question:
Do I have to change my gear ratio when I activate the timing advance/turbo on my ESC?
My common sense is saying yes because activating that feature will generate more heat.
If I am right there, what would be the ideal gear ratio for that mode?
Respectfully,
Sagad

Yes. 5.5-6.0 is better for boosted settings. You need to do that as you increase the rpm of the motor and move the torque further up the Rev range depending on how much boost you are applying. Chances are if you boost 13.5 at 4:1 you'll fry the motor.

Now if may I add another question:
In motors there are rotors. There is one for torque and another for high revs.
How does that come into play?

If you use boosted mode, don't forget to decrease the endbell timing on your motor. Usually leave it at lower timing and utilise the ESC to pump timing into the motor

I've used both SP Pro V3.1 and SP Stock Club for my local track.
FDR for 13.5T Blinky is 3.8 and 13.5T Boosted is at 5.8. I guess different track layout need different FDR setting.
Motor can timing and Boost on ESC add up to each other.
Anyway, advice that I got before was not to exceed 60 degrees on both motor can timing and boost applied and added up together. Don't know how much of it is true but i stick to it and so far no smoking motors...yet.
Happy Racing !

Then what would be the standard timing for boost/turbo? 0 deg? To avoid smoking? I smoke but I don't want my RC to smoke.
Additional questions:
There are stock motors, spec motors, and mod motors. What's the difference? I'm guessing in stock motors, timing can't be adjusted?
Please also I've been reading about rotors. There's torque and high rev. again what's the difference?

As a generally starting point for going from blinky to boosted use the following.
Blinky FDR*2-1 = Boosted FDR.
4:1 blinky = 7:1 booted.
Gearing is dependent on the rotor but I found the 12.3mm broad power band rotors to be optimal for boosted.
Reduce the can timing to 15-20 deg.
Set the ESC boost to 35-40 deg and turbo 15-20 deg for a 13.5T motor.
IE if you run 40 deg boost use 15 deg turbo.

Thanks for that information.

Unless the majority of where you race is on a flowing, high speed track I'd be more inclined to get a torque motor although it is an individual preference. I'd rather have the power to get out of the corner than to be worried about the slight lack of top speed.

I was thinking the same sir. Compensate on gearing I guess.
