Mr Stancombe email me and said start at zero and test and advance until you lose performance or the motor starts to get too hot.

THanks everyone.
 
A 2030 kv motor will survive best at 0 deg. timing. I found for racing i was able to go up to 7 deg. I tried more than that and burned a motor. If your going to run for fun, stick to 0 deg. 

Going up in timing only adds a couple of mph and is not worth burning stuff up. Another consideration is if you run in hot weather or cold. In cold you can get away with more timing but not hot. 
 
Timing of ESC is always for efficiency.

Diameter of prop is for speed ( but at Stock 36-56 under control of temperature)
 
My Swordfish and ZTW have a timing option of "auto". Has anyone tired it? What exactly does "auto" do? I am guessing it starts at 0 and advances according to an algorithm based on rpm, amp, throttle position, etc, but I can't find any information on it. I emailed Swordfish and ZTW and received no reply. I guess they are keeping it a secret.
 
Hi,

if we speak about timing we have first to know what is timing ?


As all in our world need time to do it happens also to electrons. Going forward and at the next moment someone told them to revers going back need time. Say it to a group of three people they switch fast the direction. Say it to group of some houndred man it took a lot moore time to

revers all. The same with electrons . low ampere need less time and high ampere consupmtion need a lot time. So wy do we do this timing. It is also similar to a combustion motor. To ignite the

fire in the camber takes time and is best when the piston is just at the top a little befor, so the pressure rise at this moment to its highest level. To ignite to late will waist the force to the exhaust and to early will break the moving piston just runing to the top. Same inside an electric motor , you have to switch on the electrons in the coil at its best position just when the coil stays in the middle of the corosponding magnet. With old brushed motors it was easy to fing the right position as you have to run the motor with a propeller that give the load you want and than the brushholder was set to the postion where the motor show the lowest ampdraw at this load. To early rise the ampdraw and to late rise it. So to get the best timing position you need to find this angle where to switch the ampdraw in the other direction. With todays esc it is not that easy. You have to drive a propeller that load the motor to the amps you are looking for and now you have to change the timing angle. The best point is where the ampdraw has the lowest level with this load.

What happen if we try to less timing angle or to high angle. All this will rise the ampflow. and heat the motor moore than needed. To less is allways not very good, so zero angle will most be to less.

So lower angle about 10 up to 15 degree run most well. Some outrunner need a higher timing as the controller have problems to find the back signal, so it can happen that they need something up 20-30 degree. But have allways in mind that with such high timing angle you have to give the ampdraw a closer look. The higher timing angle will also rise rpm of the motor . For some situation this is a wellcome tuning option. Maybee to get the last speed out of a given setup we can rise the timing higher than the best switching position. This give you higher revolution to the propeller but with higher ampdraw . This is only good if you know how to fine tune the drivetrain and if you look allways at the ampdraw and the motor temperature. Maybee hot , to hot. This is different to the use of electric motors in cars. Rising rpm with a propeller any in air or water will,rise the power you need to rev it. In cars it belong to the gear setup where you can gear the car to a slower topspeed at best switching position , that will give you better acceleration and know you can switch to higher timing angle to get a better topspeed on the straight.

So please if possilble messure the ampdraw and tempertur of the motor and set timing normaly to the best position . This will give you the longest runtime and the healthy motor and controller.


All realy good automatic timing will allways find the right timing position at the best . But there are some controller out that switch the timing by only looking at the ampdraw and set it to a knowen position . Maybee good if you run a motor and controller from the same company.

If not, know how and look closer.


Happy Amps Christian
