What is best timing for Fightercat 3126 motor 2200kv

[Brushless55]

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.

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...

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

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.

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.
