Default LRP X20 timing help

I have a 21.5 PRO X20 I will be installing into a tamiya mini.
Can someone help me out with adjusting the timing on this motor?
I read somewhere about flipping the inserts for more timing advance.
If there is a list of what flipping gives I would appreciate it.
Thanks

Youtube the lrp vector x12 the video has it in there and it's the same for both I believe.

LRP-X 12 series timing info
4-dot = 27.5
3-dot = 32.5
2-dot = 37.5
1-dot = 42.5
0-dot = 47.5
You read the timing with the dots facing you.

Wingracer,
I have the X20. The blocks are marked with the motor timing, not dots, but I assume the ammount of sensor rotation would be the same.
What I am trying to figure out is if a flip the 27.5 and install it upside down what timing does it give me.
I read somewhere about flipping the inserts, but I can't find it now.
I am presently running 70deg advance with my killshot and wanted to know which insert would get me close to the same.

I am just trying a couple different motors out of curiosity.

If it's the same as the 12 then 27.5 reversed would be 47.5

Would flipping all other blocks add 20deg to the marked timing or is there a math formula to figure out what each block flipped would be?

If you look at the inserts, one has a lot of angle to it, one has a little angle and one has no angle. The one with a lot of angle is +10 one way, -10 the other. The lower angled one is +5 and -5. The un-angled one is zero either way which is 37.5 degrees.

Ok, it looks like LRP made some new inserts for the 20 and put the degrees on them but only on the low side, not on the high side. Dumb. Here is what you need to know. The sensor has 37.5 degree of timing built into it so if you look at the insert that has no angle built into it, that should also say 37.5 on it.

Then there is one that says 35. That means it is reducing the timing by 2.5 degrees. So if you reverse it, that's adding 2.5 for 40 degrees.

Next is 32.5. That's 5 degrees back so flipping it is 42.5.

Then 30. That's 7.5 back so reversed is 45.

And finally 27.5. 10 degrees back so backward is 47.5 and max timing.

So after reading what you said and looking at the angles of my blocks, here is what I think.
Please tell me if my thinking is off.
Blocks listed in order of largest angle to flat.
27.5
30.0
32.5
35.0
37.5 (flat)

So if I flip, they should add 2.5 degrees the other way?

37.5 (flat)
40.0
42.5
45.0
47.5

Does the X20 have any built in timing advance, or is the indicated 30 on the block give a true 30deg timing advance.

Sorry about all the questions but I am new to brushless motors..

That's too funny, I was looking and typing at the same time you were!
At least we came to the same conclusion.

Now my last question, any built in timing?
