Cheapo ESC settings

[Jeff Wohlt]

Just wondering on some of these cheap himodel, mystery and suppo, etc ESCs how you all set them up.... soft start, hard cutoff, auto throttle auto range setting or 1.1-1.8, etc

Also, my end caps are getting pretty hot and I have epxerienced shut downs so I probably need the extra caps on it to run it cooler. THought the LVC was hitting but not with full lipos so I set it to soft and can see it slowing. Then she comes back up after a few seconds.

I am running a MM with 9Xl and X442 prop with this one.

Give me any thoughts you have. Timing on this one is only two ranges...2-4 pole and then outrunner timing....high. It is water cooled and the rest is only warm after some hard running but the caps are hot.

Thanks,

[Jeff Wohlt]

Anybody?

Jeff.
With my Hi Model GX200A ESCs I set the following;

Lipo Voltage...........Whatever I'm running, usualy 4s.
Throttle range........Auto.
Accelerate mode....Low.
Brake.....................OFF (most important).
Rotation.................Default.
Cut-off....................Soft.
Timing.....................7 or 15 degrees depending on the motor/load/revs etc.
PWM setting...........8KHZ.

Cheers.

all the ones i have use have multiple timing not just 2 options,you may have a old version
i have ran them in my MM with a 8xl on bigger props and had no problems but short 1.1/2-2 min runs

I am running with bec and the caps get hot but the ESC is just warm and it seems to want to shut down after a few laps. Then it comes right back up.

My radio Tactic 2.4 is sitting on CF but it only has a pice down the top of the MM tunnel floor. COuld I be losing signal and then it comes back up?

Wonder if I need to get rid of the bec and put some etti caps on it. It should run cooler at the caps, right?

i havent had one with built in bec just opto, except for the one that said opto and had a bec and blew the esc,ubec,rx after i connected a ubec up as it was suppose to be opto
i would disable the bec and try separate rx power see what happens
if its cutting out with full battries maybe the lvc is faulty,try disabling it see what happens
problem is there is a few different programs for these esc,s

[ozzie-crawl]

this is the programing i use if its himodel or mystery http://www.himodel.com/en/rc_manuals_url.php?id=91

[Jeff Wohlt]

Thanks, I think I need to get rid of bec first. I hate those...just issues and many say do not even run above 3S

Those instructions do not have a brake off mode that I see.

I thought I may be losing signal with the CF but it seems more like a LVC. I can't turn it off but I can lower it for cells such as NICD, etc. When I set it to soft cut off then it does it...when I set it to hard then it just shuts off but then starts right back up but then will cutout again if pushed. I have it set for 4S which I am running 2S packs in series.
Other than that she is great and I found them real cheap. Still think it looks just like a turnigy and am considering trying a programmer card.

I still need to get the caps to run cooler...will adding another cap do it?

[ozzie-crawl]

do you have a picture of it geoff i have not seen a himodel/mystery that looks anything like a turnigy
and yes you cannot disable break all together
but there is a few different programs used in these, have a look threw this http://www.rcgroups.com/forums/showthread.php?t=657606

Hi guys.
I only use the 3s-8s version (with BEC) of the Hi-model GX200 ESC for the very reason that you CAN disable the brake completely.
Having brake that automatically applies when you let your finger off the trigger is what kills a lot of ESCs, especially if you are running it near its max voltage & or current capabilities.
I always use the BEC in my ESCs & haven't blown one yet. Thats mainly on 4s but I have run 6s a few times with no problems. I wouldn't even bother to try them on 7s or 8s. I don't think they will last long.
The BEC can always be disconnected if you don't want to use it. But in my opinion the 8s BEC version is better than the 7s OPTO one.
Here's the programming link.

And here's what braking can do to your ESC.

Not sure about this, but going to throw it out there anyway. Have you considered that although the ESC is cool, that the temperature probe is close to the caps? If so, you could be encountering the thermal safety circuit if your ESC is equipped with one.

Just a thought.

[Jeff Wohlt]

It does have a thermo sensing cutoff. I may peel the shrink back and have a look at what makes this one tick.

Love it except for that issue...which I will get resolved. It is pushing 9xl 4S and X442 prop and pretty heavy at that.

Also, stock setting says motor turns clockwise...do you change that or just leave it and reverse the wires? I changed that as well to run counter clockwise.

More caps will reduce their temperature. The new larger UL-1 cap (35v 1500) would be a verygood option. I haven't popped one of these yet.

[Jeff Wohlt]

Thanks...I did finally see ore timing options. The default is clocwise rotation so I set it there and the swapped the wires. I did 1 degree timing at it says for 2-4 pole motors and this is a fiego 9xl.

What timing do most of you run on this motor 1 or 7 degrees?

I tried to look at the caps to find the numbers and I think it says 35v but will double check.

I was considering popping a etti capp board on it but if just adding another cap inline then it would be easier and smaller.

Do oyu just solder the cap to the batt wires before it goes into the ESC?

Jeff.
I run a 9XL on 4s with an X645 in a 31-1/2" mono with no problems on 7 degree timing.
Also a 7XL on 4s with an X640 in a 29" mono with 7 degree timing. Again, no problems.
Also an 8XL on 4s with an X440/3 blade 33" hydro with 7 degree timing. No problems.
All this on the Himodel GX200 ESCs.

It must be noted, however that the runs or races are for 5 laps & it's all over in about one minute, so longer runs may require less prop.

I think it was Fluid that suggested 10-15 degree timing on the XL type motors but I can't remember the thread. Maybe he could elaborate a bit more of you contact him.

Cheers.
