What is best timing for Fightercat 3126 motor 2200kv

[monojeff]

I have not yet run this motor and would like to know timing range for this motor from people actually running 1.
It is 3126 2200kv

I have tried bench testing other motors but don't hear much difference when adjusting timing to see what runs smoothest.
Maybe I'm doing it wrong?

[Brushless55]

I think these like 15* Jeff

[keithbradley]

I run 5 degrees.

[monojeff]

Keith do u run 5 on all the out runners?

[carlcisneros]

Those should be run around 5-10Deg

5Deg is a very good timing for them tho.

[Brushless55]

I think the site recommends 15* but I'm not sure what the gains would be?
and I know some outrunners like even higher

[ray schrauwen]

Even though it is an outrunner, it is high KV so, I'd side with Keith since he is fairly experienced with these motors @5*

Anyone else try 15 or higher??

[keithbradley]

Keith do u run 5 on all the out runners?
No, the larger, lower kv motors like a little more. I ran my 3740s at 10 degrees.

I ran the 2200kv 3126s in an ekos twin with twin castle ICE ESCs (before they made the marine versions) and data logged them. On 5s it ran 70's, with a best of 74mph. I tried higher timing and saw an increase in current draw and heat, but a decrease in speed.

Thanks Keith sounds about right from what I know of other similar motor out runner or not higher timing isn't always the answer.
Keeping temps down is always important.
Why push it for a 1 or 2 mph gain its just not worth it.

I have the monster 2000kv motor also suspect 5 would be good for that 1 also?

interesting but some are finding out that higher timing on this outrunner is better
again some outrunners like the high timing thing
taken from FC website..

"Finally had a few runs on it and am able to give a short review. Excellent motor for the money! I run one in the Bling Rocket, 4s, 180esc, and a M445
prop. Runs low 50mph and amps are below 160. The heat was a little high, only because I had timing set at 15. Once I bumped it up to 22, it came
down alot. rnrnAlso have one in the C/F Fighter Splat that I will be running a 5s 3300mah Lipo. Results to come shortly. rnrnI gave the motor a 4
star, only because in my opinion nothing is a 5 or perfect for that matter.rnrnGunny"

[monojeff]

I just don't understand how to know what to put these motors at obviously can start low and move up with some testing and see where it goes.

Scares to me play with it to much I'd rather go with what is known to work.
I do not want to burn up a motor in 1 of my scratch built hulls to much time invested.

How do u know what to high or to low timing would be?
Also know it depends on the setup and prop.
So many variables and room for error!

[Mattwarner]

Well this is interesting as I have twin 3126's in my rivercat (1600kv) and they are set at 15' but first run with 45mm props and they were very hot (couldn't touch) I will try 5' as suggested

[keithbradley]

There is always the possibility that an ESC's timing could be poorly calibrated.
However, the person who posted that review was completely green to FE. That was his first boat, and first motor he's ever ran. I also don't recall which motor he was running...if it wasn't a 2200kv, his review would be totally irrelevant.

I'm not sure why you would post 2nd hand info from an inexperienced user that is in conflict with the advice already given. It just makes it confusing for the op. If you don't have personal experience, its best to defer to those who do.

[boater57]

Now I'm confused and I thought I had this part down. I got a 2200kv outrunner from fightercat, the motor page said these were suggested 30 degrees timing. My sk120 esc only goes into the 20s so that is where its set. My other outrunner is a t500 in a P1 KOS. I think I read on here 15 degrees. Are my timing settings in the ballpark?

[monojeff]

Keep us posted Matt on how it goes.

Keith what's the largest prop you have ran on this motor and had ok temps?
I am not sure what an ok temp is on these motors?

Hoping I can spin close to a 447 for my modern 1/10.
If the smaller motor won't handle it certainly hope the larger 2000kv will!

First that came from the FC website on the 3126 2200kv webpage

And to tell someone they can't post on the FC site because they are green in FE?

I've also read on that site they suggest 30* timing on some of these outrunners including the one I bought from them

also in 3 d flying some of our planes fly better at 20* and some better 30*..
most factory escs are set to 15*
and I've seen 1 fast 115mph SD50 on 8s set to 10* as that was the best setting for that motor...

[boater57]

Propper chopper, Ineed your advice..............4s on 2200v with 120 sk esc's, Timing? I'm lost apparently.

[monojeff]

If you look at FC page it says 5-15 degrees this is where Ben told me to start.
Wanted some experienced people to chime in with what they were using in their setups.

So do you think this motor can push a 1/10 scale hydro around 6lbs and push a 45-47mm prop?
How many amps do you think it will pull?

I do think it's a good idea to start low and go up..

I have the 3730 1600kv on a impulse and Kos. Setups are are similar on both boats, seaking 180a esc, Kos is running a m445 and impulse is running a FC x443. Timing is at 11.5, I tried lower timing and worked my way up, If I was running another esc I would be happy at 10 deg. My motor temps were a lot hotter at 15 deg. I'm at around 130-140 at the, no cooling to motor and I live in humid and hot Texas.


I understand it isn't the exact same motor. Just giving you a insight on something similar.

I run 10 degrees on the 3740 and 3730 outrunners also (I'm not sure about the 2000kv...I don't know what wind that is).
These were originally stated to best run at 30 degrees...those of us that tried different timing saw drastic improvements at lower advance.
I spoke with Ben about this a while back...I think he actually changed the site as well, but I haven't checked.

[keithbradley]

Propper chopper, Ineed your advice..............4s on 2200v with 120 sk esc's, Timing? I'm lost apparently.
Try 5, move up to 10 and note the difference.
Every setup is different, and the effect of timing changes can differ depending on load, RPM, etc. I do think, however, 5 degrees will be a lot closer than 30 degrees.
74mph is pretty respectable with 2200kv/5s/x442 props...I don't think I would get there at 5 degrees if 30 degrees was ideal.

[monojeff]

Yes Ben did change the site.

What does that boat weight Keith?
Do you think the 3126 is capable of pushing a 6lb 30" boat?
In the 50mph range?

I'm not sure what the 2000kv wind is either I know it is a beast of a motor though.
It is huge in comparison. I guess I'll start low and go from there.

[Mattwarner]

These motors are pretty small, not sure it could be described as "a beast" especially next to my 5692!

as mentioned earlier I run two in my rivercat/apparition and with 45mm props on 6s it moves well, maybe 60mph once set up properly, but I certainly wouldn't want to run a single 3126 in anything more than 25" and even then I would be happy to see 40's

[monojeff]

I don't think the length has much to do with these motors as much as weight does.

The motor I am referring to a beast is the 3740 FC outrunner.
It's going to be a challenge to even fit it in my 1/10 scale in building.

We run scorpion 3026 motors without a problem in these boats.
1210kv and 1900kv they push the boats in the low to mid 40s no problem.

[Mattwarner]

I see what you mean, agree the 3740's are beasts!

Just so you know I ran tonight but propped down to 40mm props from 45mm and ran at various timing settings but I didn't find any that reduced the heat, didn't have my temp gun but tried everything from 3.75 to 22 degrees and all were too not to touch after a 2 minute run :-s

Ay ideas?

[monojeff]

Seams something is up.
I would think you should not be having heat issues with that setup.
Specially since your running twins?

40mm 2 blade props?
Also what are you running for batteries?

[keithbradley]

Jeff,

I'm not sure how big you could go with a hydro...I would compare these to the 3026 scorpion outrunners though in terms of power...obviously the scorpions are a bit nicer, but the suppos have comparable power.

Matt,

Make sure you are getting that thing aired out!

[monojeff]

Awesome keith good to hear.

That was my thoughts on his boat also.
Sounds like its running wet and causing lots of drag.

I'll post results here once motor is ran in 1 of the 1/10 scale hydros.
