How we suppose to know how many degrees of timing at 0 on the can has any motor? I don't think this is an info that manufactures provides with the specifications on the manual when we buy a motor.Where we can find this info?It would be very helpful.

I know by metering alot of motors.
Here what you do.
Always use a fat rotor, and with no load on the motor, start at - 10 degrees of timing and hit full throttle with a watt meter hooked up between the battery and speedo.
Target amp draw.
13.5 motors - about 23-25 amps
10.5 motors - about 20-23 amps
and so on...
Read amp draw.
Your looking for the sweet spot where you get max WATTS (power) for as low amp draw possible.
Thats where you get max efficiency.
Its like dynoing your Motor and Battery together.
Remember WATTS (Power) = Volts X Amps
Gear to the motor. Run no higher then 160 degrees on motor.
Your good to go...

Actually i'm not asking for this.I have seen people saying, Nosram Pure with oooo has 27.5 degrees timing,Trinity D3.5 motors has 30 degrees of timing at 0 ,Novak has 25 degrees of timing at 0 etc.I would like to know how they got this info.

You can use a degree wheel a small one.

Fat rotor?
You do not need to know about real 0 degree timing is on the can.

I assume I need to look at Kv and use in that in place of watts
or how do I convert kv to watts

To find the sweet stop or where you get max efficiency.
You need to adjust the timing ring one degree at a time and take a reading.
Once you find the highest point of power (Watts) at the least amount of amp draw then your there!
Watt meter is what you need.
KV and rpm don't tell you anything IF its NOT under a LOAD!

Mr. RCTech, sorry to be so newbie but, are you finding the sweet spot using the combined time of the motor and esc? So if the motor has 30 degrees and the esc has 10 degrees, you adjust the motor or the esc? Or do you set the esc to 0 degrees and adjust the motor timing, then add timing during boost?

if between the esc & motor which wires do you connect as there are two wires on the input/output but 3 on esc & motor.
Sorry if I appear a bit thick on this LOL!

Rctech, I'm also new to this!
Could you do a step by step of the process? I understand how to wire it up, but I get confused with all the different timing etc!
Here's my current setup: orion r10 pro, reedy 13.5 sonic Mach 2 (we run boosted)
10 turbo timing, 10 boost, on motor it shows 20 and that's how it came.
I don't have other rotors!
So plug it all in, should leave all timings as they are? Wheels on? Or take pinion off motor?
What order to you change motor, boost and turbo timing etc etc???
You see how fresh I am now!! Lol
Your help would be much appreciated!

That part about gear to the motor, run no higher than 160 deg.
I don't get that! Is this spur and pinion combined or the total of all timings?
I though we should not go over 60 deg total timing?
Does that also mean I can go much more with my turbo timing? Don't wanna fry motor!
