Motor timing....

[brokennib]

I was wondering if anybody has advanced the timing on a motor instead of adjusting the gearing. I just installed a goat 3s system, with a new 18.5 motor. I noticed that the factory timing is set pretty tame, so I wanted to advance it just a tick for a little more oomff.
I'm just curious if anybody's experimented with this, or has any experience with Novak's brushless motors. I don't want to stress this system too much.(Or ma by I'm just paranoid);-)

I advanced mine just a tic on a Ballistic 18.5 in a LCC. It does fine. Its hard to say if it really helped wheel speed any, but its been that way for a while now.

Advancing t timing is a good trick when the next higher gear is too much. It's sort of finding the midway point between two gear ratios.

Thats what I'm thinking, I just don't want to drop a lot of torque. I'm sure it'll be fine.

The torque will be an issue.

If you move the timing forward you'll get an Increase in RPM and a Decrease in Torque. If you move timing Back you Increase in Torque and a Decrease in RPM.

If you take the motor out and mount it in a piece of aluminium you can manually adjust the timing while the motor is running and see the effect it has.

The biggest problem you'll face is using an 18.5 turn motor - If it's for a crawler it seems to be very high - the rpm will be through the roof anyway. You could always look for a motor with less turns and more torque, they aren't that expensive if you're running a brushed system.

He is talking about a 18.5t Brushless motor not Brushed..so the speed isnt quite as insane (still fast though)

Yeah i would use the time adjust on the motor to find the mid point between gears...so if stepping up to the next pinion is too much bump the timing a little bit and so on.

Works quite well actually. Have done it on my SCT when i was still racing.
