EPIC "D3" Duo 3

I have to admit I was wrong about where I took the measurement because the OD of the plate that moves the sensors is only 1.140".
However even calculating out those numbers in degrees still comes to roughly 2*per mark, 2* in the blank space. So by going from the center of one hash to the center of the next is still roughly 4*.
Again measuring;
1.140" x 3.14 = 3.579
3.579" / 360 degree = .0099" per degree
If indeed each mark were 8* the measurement would be .212 for 45 degrees. (As measure right from the hash marks) whereas 3.579 / 8 (45 degrees) = .447
.447 is 2.09 times that of .212 meaning that Trinity's "8*" is mathematically really 3.8* going from one hash mark to the next.

A degree of movement is a degree of movement.
Just how much an increment gets smaller for the smaller diameter that is being moved.
While I had my calipers out, I had a Duo 1 sitting on the bench I decided to check it's degree accuracy.
It's degree points are based off of 1.257"
X 3.14 = 3.95 / 360 = .011" per degree.
Guess what..... The 10 degree mark is .110 from mark to mark.
.011 x 10 = .110 perfect (roughly)
And if Jim Dieter says it's 8* then it's 8*.
But it doesn't add up. Even because the sensor ring is smaller it's being adjusted on the circumference of 3.579.

Yes I'll agree that a degree is a degree. 360 is a circle! LOL I just didnt know if the measurements on the outside could be different because its referenced to a smaller circle.
I dont personally care how many degrees it is as long as its fast when I get it right! LOL

I'm sorry but it doesn't add up. Physical measurements don't lie.

It's funny this is the current topic cause this is exactly what I was playing with at the on-road track last night. Personally, I liked having max'ed timing with the proper gearing to maintain proper temps vice 0* with the right gearing for temps (no ESC boost). Seemed like there was more power everywhere, top and bottom. I couldn't compare lap times because I was making suspension changes as well. And yes, it's fast!
And Racecrafter after looking at a duo 2 you are correct. On the duo 2 each long line is 8 degrees. So the in between would be 4 degrees. They did not put the long lines on the D3 motors.
Once I looked at a D2 I remembered that important part!! LOL So your math is correct.

Yes for 0 Timing class full timing is the best. This is where the motor makes its most wattage and RPM at but unlike other motors it doesnt drop off in efficiency near as much. Maybe 2-3 points diff in eff between zero and full timing. Most motors drop 8-10 points.
So the final word on the Duo 3 markings is 2* per space and mark correct?
One last ???, the "zero" or large hash mark is a true zero timing mark? Or does it reference a stock setting of some value?
