Saw someone asked about motor timing earlier, I am wondering what are the best BLHeli settings for the emax rs2205 2300KV red-base motors?

I am using these motors with littlebee 20A on BLHeli 14.4.

What's the best demag compensation and motor timing settings? 

The magnets are quite big, so I would think this would create much torque and needs some tweaking on the demag and timing.

I have default settings, except medium high timing and have active braking enabled (damped light). Works fine for me.

It's the same setting I use on the 2204 Cobra 2300kv. I haven't look too deep into that, so I can't say it's the best setting though. But it works fine

If you use airmode in betaflight, turn demag off.

Demag helps with motor stutter/stalls so if you don't have any issues with that then just keep it off. Timing depends on what you want out of the motors. Higher timing gives the motor more top end but less torque. Lower timing gives more torque but less top end.

I read on the the blheli wiki and instruction on the blheli page about what each setting does. The timing thing is standard info. Before brushless motors, you would change the timing on the motor itself by rotating the top of the bell housing to change timing. Now with brushless its the esc's that change the timing.

With the rs2205 you can run high timing without any issues since they have amazing torque to begin with. Setting timing to low with them will max the torque but you will notice the difference in top end speed. I have the rs2205 and the mt2205II and the sweet spot for my setups is med/high timing, damped light on, demag off. Running lilbee20 and rg20 esc's on 4s and 5045bn. Most people just keep to default settings though as it won't make much of a difference to 90% of pilots.

You can run a tighter tune with dampen light on. Example: you do a fast roll to the right, when you snap out of the roll your right motors will blip full throttle to stop the roll. If dampen light is off the inertia of the prop blipping wide open throttle will cause a bounce back. if dampen light is on it can slow the prop down quickly to stop any bounce back from happening.
