Do you want the quick answer or the long winded one?
I'll start with the quick answer. I would leave the timing in the same spot and test. Then I would drop the timing by a degree or two...

Actually that does make sense. The balance port also senses the actual voltage of the battery and not just what the charger is putting out. In other words, there is a voltage drop across the...

Any progress on this?
EDIT: And do you have the Simple Dyno software? I checked the github link, but there is not a packaged zip file that I can find.
EDIT: And sometimes you just got to click a...

All terminals I have seem sit below the plastic case, so it is unlikely. However, if you want to be extra safe just get some 4mm or 5mm rubber stems to put in the terminals.

It isn’t a big change. I only noticed because I was making sure the arm was the right length and put them back to back.

New arm is on the right.

Finally got all my parts to put my car back together. Interesting discovery... I bought a set of arms, C204-S. I thought these were a direct replacement for the stock arms (well, I guess they...

I would like to clarify my experience with my R1. My motor was used for testing purposes and was soldered onto multiple times before the insulator ring started coming apart. Personally, I have not...

Did they send out a new stator? I actually asked them if they could just replace an insulator ring an their response was no. That design is not the best. I used some golf shaft epoxy I had laying...

It has not been my experience that the R1 rotors are very strong. I have 5 R1 v21 motors of different flavors and the strongest rotor I have is 1720. Rotors are a crapshoot with R1 though, they...

That is not an issue I am having. Although I still haven't had much of a chance to mess with it. I have been absolutely swamped lately. But I am almost caught up on work, so we'll see.

You should still be able to get close to 30A with the 5 1ohm resistors. I just wired up a discharge bank in series to my 308 and was able to get 26-27A with a bank of 5 1ohm resistors. The way the...

As stated above it shouldn't make a difference while charging. But for an IR check, yes, you can just connect the sensor lead to the positive side on the battery. DRC sells a 1s/2s switch and its...

How big is your encoder wheel? I can print one in PETG, or even PA6-GF. Haven't had a chance to print with the PA6 yet, but it is supposed to be dimensionally stable.

Would you care to share...

Your angular velocity will be the same no matter where you are on the disc. Linear velocity will change, but that will not matter.
Do you have any gear reduction at all in the setup? 15ms is...

While Roelof post will definitely get you to some usable values, personally I would use 5 x 0R5 (0.5 ohm) 100W resistors. You can get away with 50W, but the 100W will stay quite a bit cooler and...

If you want to, you just wire the positive of the fan between the battery positive and the resistor bank, then the negative to the negative. However doing this you are only going to get 3.2-4.2V for...

Parallel will look like train tracks. Line the resistors up longitudinally adjacent and run a wire down both ends. Series would be your old school string of Christmas lights.

But in this case you...

Call it OCD if you want, I don't have a rational explanation. Well, I do, but not one most likely accepted by the masses.
