Brake and timing settings for 30% Extra 260

[ChopperUp]

hi all,
i am running a hacker A60-18L with a cc110hv esc in an 87 inch extra260. the thing flies great with the esc factory default settings. however, i am wondering if i should turn the brake off and/or adust the timing for better performance.

any thoughts/info/advice about timing and braking would be welcomed seeing as i know virtually nothing about them.

thanks in advance.

Brake should be set to off, or at least set up an idle-up so that the prop doesn't stop in the air at any time. Should probably set up a soft start and set timing to low advance - I think those two are the default settings though.

Thanks bodywerks. I think the default was soft start, soft brake (50%), and medium timing advance. I will set it to low advance and disable the brake. I still don't understand what timing advacne does exactly though.

I've never changed the timing on any of my electrics, always left them at factory, and the brake is always set to off.

The brake is definately set to soft (50%) by default. I checked it with a Castle link programmer. When I change it and then press the factory defaults button it goes back to 50%. Plus, it makes a 'bong' noise and the prop stops when I bring the throittle stick to 0.

I did get some feedback from a guy in my club about what timing does though. He says it has to do with where you want your power range to be. Lower timing = bottom end torque and more advanced timing = higher end rpm.

Does that sound accurate?

Timing affects power and efficiency. Lower timing means more efficiency, but less power. Higher timing means more power at the expense of heat and efficiency. Medium timing is a good mix of both, and the higher timing doesn't add all that much power so it's usually not worth it. I run low timing most of the time.
