Timing on a feigao motor

[m4a1usr]

Some good reading for setups from Neu.

There might be some issues with the correct motor timing if the ESC you are using has a higher PWM selected.

I just came back from the lake to try out my new Turnigy 120 and i loved it. Problem was i didnt get much of a run time because i had the volage cut off to 50% set to high. By the time packs got warm it cut back the power..ooops! So friday i will test a noon with the timing at around 15 degrees or so{in what little water thats not frozen}.Then i will drop it to 0 just for the hell of it and see what happens!!! I know my Castle 120 would go an average of 58-62mphset on Race so i hope to be in that range again with this ESC.I will let you guys know.

Gary; looking forward to hear what your thoughts will be after trying different timing runs

I have always run Lower settings on lower pole motors, and higher settings on higher pole motors. Outrunners being from 6-10 poles for example..need a MINIMUM of 11-15 degree. Feigao etc, should be run at 0 degree. I have tried every combination with feigao and anything over "low" timing makes it run hotter, I am not contradicting electricians science, but hands on tests. I am using Neu and neu/castle motors now and they run "fine" on low timing. But turn up the timing to say, 11.25 degree and they come to life, really quickly. I have tried up to 22.5 but it just runs hotter, not faster.

Thank you for your great input!
I've heard others with the same finds as you..

From what I have tested, Fiegao 7S with a x632 in a Splash hydro, the boat was ok on zero timing BUT when I advanced it to 7 degrees.... I will tell you that little hydro sure woke up! GPS at 38 MPH. on 6 cells of NiMH. so zero in this case just did not cut it.

What speedo and software version if you know? I'm thinking there might be some underlying issues we may not be including when making timing choices. Something seems amiss.

X power from this site, and set at 8 KHz, yes I started at zero like most people said, and the boat was ok, but I got the itch to make it go faster on 6 cells of Nimh.

Ok. My test day was probably not as accurate as some other people would be but this is what i came up with. Air temp was 38degrees, water 49 degrees. My test patch of non iced water was not that big but i tried anyhow. Batteries where pre heated to 85 degrees. First test was 58 mph with timing set at 18 degrees. Second test was 54 mph at 15 degrees. Third test was 53 mph at 11.25 degrees. I than lost comunication with the ESC because somehow i hit something" button" on the transmitter and heard a beep between swaping battries and the ESC was not seeing the Transmitteranymore..... " I kinda miss the simplicity of the Hydra".....Anyway It was to cold at that point with wet hands so that was it for me. Each test was recorded on my Eagle Tree Datalogger and a new set of batteries where installed on each of the runs. Four runs per pair of batteries. I will head back sat. afternoon if it doesnt snow to bad and try and test all the way down to 0 timing. Boy.........I used to love winters ....now i can barelly tolerate them LOL

I saw one of those turnigy 120s do alost the same thing. First it just didn't give full power then it kept going into setup mode then no worky at all. Later that day and till today runs just fine. And no this one didn't get wet.

BTW I run mine at 7 degrees good ballance between power and heat. The turnigy came setup with 26 degrees timming and it was an animal. It's now set at 3.75 with less speed and cooler temps.

From old Hacker master esc instructions

4 Timing Modes
• Timing mode 1 – (2-5 degrees) optimum timing for Hacker, Lehner, and other 2-pole motors
• Timing mode 2 – (10 degrees) optimum for Aveox, Astro, and for maximum RPM on 2-pole motors.
• Timing mode 3 – (18 degrees) optimum timing for Phasor, Mega, Plettenberg, and other 6-pole motors
and for maximum RPM on Aveox, Astro, and other 4-pole motors.
• Timing mode 4 – (30 degrees) optimum timing for AXI, Kohler, Actro and other Out runner motors

Good start. The 30 degrees for outrunners is a little on the high side but otherwise this chart is right on the money.

so it looks like low timing on a Feigao is the way to go...

Went back today and did back to back test of 3.75 and 26.25 degrees . I did this because it was cold as sh@% at 28 degrees . Water was 46, batteries were around 80. First run with 3.75 timing was 51.9mph and last runs was 60.0mph with 26.25 degrees.High timing was definetly faster. Didnt take any temps because frankly its 28 degrees out and i dont see anything getting warm......especially me LOL. Again not the best test but gives some insight.

Once it warms up a little you'll find more timing advance does equal more speed at the expense of heat.

Ok, how do I advance the timing on my esc?
I have a plane with an outrunner I would love to punch up the timing for some 3D fun!
