Timing on a feigao motor

[Gary]

Hi guys. I have a 8xl and was wondering where a good timing number would be. I always ran a castle 120 Hydra on normal , whatever that number would end up to be . Now i have Turnigy 120 and have 3.75 through 26.25 degrees for timing. Just looking to get a baseline with this ESC before i hit the water and waste an afternoon of batteries. A good start would help. Thanks

Feigaos being 2 pole motors require low timing. Set it at 0 if you can.

Gary, not sure which Turnigy esc you have but it should have a setting for 0 also, I run my DF29 with the Highmodel 200 and 8xl at 1 degree and with all the tests I did this setting runs the best. My Turnigy 180 has a setting for 0. Try it on 0 first.

I have the Turnigy 120 amp 6s model. Wow ...0- degrees .......I would not have thought that low but thts where i will put it.

No no no no! This is absolutely not correct!! Setting the timing advance on "0" will often give high temps and poor performance, particularly if you prop for speed. Only the Neu "D" 4-pole motors want timing near 'zero'. For sport running with a Hacker/Feiago/Lehner 2-pole motor, aim for 10 to 15 degrees advance (unless it's in a tug boat). They will run a little faster at 20+ degrees if propped right in a very free running hull - but temps can get high so no long run times and check temps often until you know it's safe. In fact the latter is good advice no matter what motor you have until you know what it will do.

This is news to me! Thanks for the knowledge sir.

I didn't make this up, it's from eight years of BL racing experience, and from the recommendations of my German ESC programmer/FE racer friends. Too, the instructions for Schulze controllers stated that for Hacker 2-pole motors (Feigaos are ripoffs of the Hacker) optimum timing is 10-15 degrees. The lowest you could adjust a Schulze was between 5 and 7 degrees anyway. Even Castle recommends their #2 advance setting for the best balance of power and run time.

Timing advance is required for optimum power and efficiency matched to the current draw. The higher the draw, the more advance is required. Since most of us want high performance we need to adjust timing to match higher amp draw. Too little is as bad as too much.

I may have to try this out on my MM that I run a 9XL on 4s and 5s, because it looks like it could run better than what it does now..!

News to me also, Thanks Jay. I did try the setting of 7 degrees being that this is the next increase on the Highmodel 200 but found the temps to be higher. So set it back to 1 degree and temps are fine? Will have to try this out on the Turnigy at 3.75 degrees in the spring.

how about those 6-8 poles motor, what timing should I set?

[yurkanip]

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.

Those are very helpful tips yurkanip, what ESC did you use to test those motors?

"Always"? We'll have to agree to disagree here, I have 8 years BL experience with two ESC and two motor makers to back up my facts, but what do I know....

Had you tried advanced timing on a Neu 'D' wind motor you'd not find it to "come to life" but instead just get hot. When someone's "testing" disproves science, I have to wonder about their 'test' methodology. BTW anyone who wants to give up efficiency and power by running a 2-pole motor on zero timing is welcome to do so. Please by all means come and race with me.

Good Morning Jay, Always awesome to hear from the Pro's of the sport! What frequency would you use on the controller for this timing?

[yurkanip]

Fluid, interesting response. My statements are purely from my experience...I need to ask you, did I knock anything you said? or knock your, "8 years of brushless experience" I think not! I was not even talking to you in my post...it was towards Gary who started the thread. Now, please take a breath and give all of the input you want, but don't get defensive when someone has a different point of view on this forum.

Now, back to the original post about timing.

Himalaya, I have abused the same seaking 90a esc, for 2 years now. It is still kicking!
