castle 2650?

Hey guys whos herd of the 2650 running a bit better with high timing or at least a small timing advance?I was speaking with a gentlemen who told me such.We all know im talking about speed runs or drag racing he said 4 poles run better with timing slightly advanced.Well guys lets hear it chaps

better how, his statement is misleading

advancing the timing has the affect of slightly raising the kv, this ultimately increases strain on the motor and load on the the esc

your timing should be advanced based on what you are trying to to with the car and the temp of the motor

but there isnt really a best setting

Depends mang. I use gearing over timing with most of my big motors. And then you have the deal with Delta and Wye winds. They Wye's can take more timing.

Now with the 1400kv motors, I do play with timing abit and even do the boost/turbo thing.

good info

It's too bad that the ESC can't somehow measure input power and output mechanical power and increase the timing automatically for max efficiency, or max power, whichever the user selects in Clink...

Why sir i think you're on to somthing chap.

sooo zero timing will be best?Or normal

Best in what way- are you after cooler temps or higher speed?

The 2650kv is a 1512 1Y, so it will respond to increased timing much better than a Delta wound motor; stock timing is 10° of advance, so lowering it will reduce speed and temps a little- increasing it a notch will increase speed but also temps in all likelihood; take your pick...

The only absolute truth in regards to motor timing is that 0degrees is wrong. ALL motors regardless of pole count, wind type, number of winds, whether inrunner or outrunner, brushed or brushless, will benefit in terms of both efficiency and power from SOME degree of timing advance once spinning faster than 0RPM.

So guys i turned up my timing and it preformed strange.With low throttle it would just pick up speed and shoot off it, definitely increases tremendous amp draw and increased temperatures.

Im running one in a XTM Rail and for that overweight pig ( I Added bout a # in the form of a battery tray)
Doesn't like anything temp wise over 5deg timing.
Stock it would get toasty.
13/53 gearing on 4S.
Does bout 42 ish +/- 5 mph

WOW shure heats things up!!!

The timing advance with Castle Creations ESCS is dynamic, it changes with the speed of the motor. This assures the motor is running at it's most efficient timing regardless of speed. This is one of the big advantages of a good sensorless over sensored system. Sensored systems. This is possible because the ESC reads the motor's back EMF directly, not pulses from sensors. When you change timing you are simply changing the range the timing moves within. A motor will be more efficient at 'normal' timing, slightly higher Kv at the expense of a huge decrease in efficiency at higher timings and more efficient with a slight decrease in high speed RPM at low timing.

Delta wind motors do not respond to timing and at higher timing get extremely inefficient and kill batteries and ESCS. We no no sell D wind motors and it is my informed opinion that they have no place in surface vehicles and only limited use in high speed airplanes that are run for short periods of time.
