I've seen a few questions on here from folks that need help setting up their Align 35 ESC. The instructions that comes with the ESC are a bit difficult to decipher. Some purchase ESC's used, and have no instructions. I've looked online, and found a couple of guides, but they do not include the newer options found on the version G and X of the ESC. So, I've put together the following, hoping it might help someone. Please, if you see an error in this guide, feel free to point it out so that I may revise the original guide.

USE THIS GUIDE AT YOUR OWN RISK! Make SURE to use all due caution!

Programming the Align 35 ESC, Option settings
--------------------------------------------------
Option 1, Brake setting. Low stick indicates no brake, (which is what you want for a heli), mid stick indicates soft brake, and high stick indicates hard brake.

Option 2, Motor timing. Low stick indicates low timing, mid stick indicates mid timing, and high stick indicates high timing. Generally, lower pole motors use lower timing while higher poles to use higher timing. Higher timing gives more power at the expense of efficiency. For the Align motor, low or mid is fine. Personally, I use mid with my Align 430L.

Option 3, Battery protection. Low stick is high protection, or cutoff at 70% of pack voltage. Mid stick is mid protection (default), or cutoff at 65% of pack voltage. High stick is low protection, or cutoff at 60% of pack voltage. I prefer high protection, to prevent over-discharging the pack.

Option 4, Aircraft mode. Low stick is "normal airplane" mode, mid stick is for soft start, high stick is governor mode. Note that this option may not be available in earlier versions of this ESC. I prefer soft start personally.

Option 5. Throttle response. Low stick is low response, mid stick is mid response (default), high is for quick throttle response. Note that this option may not be available in earlier versions of this ESC.

Programming the Align 35 ESC, actual programming
--------------------------------------------------
Many of these sets involve moving the throttle stick to various positions. Please note that it is HIGHLY RECOMMENDED that you remove the pinion gear from the motor before attempting ANY of the following. This will ensure that if the motor were to accidentally spool up, the blades will not engage. As I understand it, you'll need to leave the motor hooked up so that you can hear the beep codes. This is why you want the pinion gear removed! Regardless, ALWAYS use extreme caution!

-Make sure your throttle curve is setup in the default 0, 25, 50, 75, 100 curve. Also make sure your endpoints are set to the default 0 and 100 settings. The ESC uses the stick position to sense what settings you want during the programming phase. You can reset it later to the desired curve.

-Make sure your throttle direction is setup correctly, so that at low stick, the motor is not running at all, but engages as the throttle stick is advanced. If yours is backwards, you need to reverse your throttle direction in your transmitter!

-Unplug the battery from the ESC.

-With your transmitter on, put the throttle stick at full throttle. This tells the ESC that you want to enter programming mode.

-Plug the battery back into the ESC. The ESC will power up, will sense that your throttle stick is in the high position, and will enter programming mode.

The ESC will emit a succession of tones indicating that setup mode is being entered, followed by a series of beeps indicating what the options are currently set at.

-Put the stick at low throttle and the setup sequence begins.

At this point, the ESC will emit a beep (or beeps) indicating which option you are setting. To begin with, it will emit a single beep, repeating slowly, indicating you are setting option 1. Simply place your throttle stick either in the low, mid, or high position, based on the desired setting for the option. Keep your stick in this position until you hear a quick succession of "up down up down" beeps. This quick succession indicates that the previous option has been set. The programming will continue in the same manner... 2 slowly repeating beeps for option 2, 3 slowly repeating beeps for option 3, 4 for option 4, and so on. Simply continue the programming by placing your throttle stick in the desired position, based on which option is being set.

After a preset period of time you will hear a scale of notes in quick succession, followed by the ESC playing back your settings using beep codes for options 1, 2, or 3 (low stick, mid stick, high stick). Listen carefully to verify they are correct.

For example, on my own heli, I set the following options:

Option 1, no brake
Option 2, mid motor timing
Option 3, battery protection high
Option 4, soft start
Option 5, high response

So, when listening to my options play back, here is what I would hear:

beep
beep beep
beep
beep beep
beep beep beep

Once you have verified your settings, unplug the battery, put your throttle stick to low, then plug your battery back in to verify that all is as you'd expect.

That's it! This was compiled using various resources, as well as my own personal experience. My settings are here only as an example. Use this guide at your own risk!

Programming Align ESC (35G)
BMCGRADY - I read your instructions on setting up an Align ESC, but I am still having problems...I hope you can help...

I am trying to program an Align ESC with a 430L motor. I will be using this in an Exceed RC Raptor G2 helicopter with the Exceed RC transmitter. I have tried everything I can find in the ESC instructions and on the web, but can't get the ESC to go into setup mode. Here is what I do:
- Set the TX to full throttle, and turn on
- Connect the battery to the ESC
- The ESC gives a series of beeps, and then starts beeping out the current settings...this is where it all falls apart
- I have tried moving the throttle to low during the initial beeps, just after the initial beeps, during the "current setup" beeps, and after the current setup beeps

No matter when I set the throttle to low, the ESC will not go into setup mode. I am at a loss. Is there anything else I can try? This is a very basic TX, and only has a few on/off dip switches in the back...no programming modes that I am aware of.

Thanks for any help you can provide.

Based on what you're describing, the only 2 things that come to mind are either a bad ESC, or something that's preventing the ESC from seeing full stick when you power it up. You mentioned in your PM that you're not aware of a throttle curve in the Exceed TX that you're using. Your local hobby shop or a local flyer there in Huntsville may be able to help you check it out, possibly by hooking it up to another TX to see if there's some sort of issue there...

Sorry... I'm drawing a blank...

bmcgrady,thank you for clearing a few things up for us all.I have a question.My esc is set up as follows.
1= beep
2= beep beep
3=beep
4= beep beep
5= beep beep.

I have soft spool up,but i chose the medium throttle response.At what point does the esc distinguish slow spool up from medium throttle response ??.It seems like if i go over half throttle it will then enter the throttle response.when does it go back to slow spool up?.I hope i did not confuse you,but this is the best i know how to describe it.I don't have much time on the heli yet,but it feels like if i never go over half throttle on the ground it will not give me medium response.

Thank you

tatara I think that spank61 is right. Try reversing the throttle channel on your transmitter. I would think that the way it is now if you turn on the esc with the throttle all the way up then pull the throttle towards low stick, once you hear the beeps the motor will start to turn. This is a definite signal that your throttle is reversed. Chuck

when does it go back to slow spool up?
All soft spool up is doing is keeping the initial spool up from "leaping" from zero to a very fast setting. Once you spool up though, you won't see soft spool again until you go back down to zero throttle again for several seconds (something like 5 seconds or so), then try to spool up again. It's just there to keep you potentially damaging something by going from a dead stand still on the blades to a very fast setting instantly. You can see what I'm talking about by spooling up on the ground to around half stick, but never lifting off. You'll note the soft start working as you'd expect. Then bring your throttle back to zero, then back up to mid again pretty quickly. Soft start does NOT engage. Then take it back down to zero again, but this time leave it there for maybe 5 seconds or so (or until your blades are nearly stopped). This time, when you go back up to mid, soft start should re-engage.

Glad you found the guide useful! Let me know if the above doesn't answer your question...

bmcgrady,i think that just about answers my question.My spool up and throttle response are working fine.As you said before,the instructions are not very clear at all.If you look at this link here in the setup instructions.Go to manuals and then the 35g esc
( http://www.align.com.tw/html/en/c_rindexe.htm ) you would think that the safest battery protection would be at the full up position according to the drawing. I am glad you posted this cause it was frustrating.

Put the timing to high advance. It's more efficient for gov mode. Make sure to put the throtle curve to 75-85%, which ever you choose make it flat curve. Your voltage cut off should be 2 or 3. Just land before voltage cut off. You will feel it when the power is getting weak.

The reason for high timing is the high kv rating of the motor. Even with only 6 poles, it's fast enough to warrant the timing advance of a 14 pole motor. You will feel more power, and the flight time will not even drastically shorten, even negligible to the point of no noticeable decrease at all.

The 2 or 3 on voltage cut off is that in high loading situation, like doing tic tocs, power punch outs, there is an intermittent spikes that the ESC misinterpret as low batt situation and cut the motor to save the lipo. You don't want to loose power on those demanding manuevers.....

You did a good choice on the throtle response. Gov mode requires fast reaction to RPM changes and if it doesn't react quick increase current draw results, and shorten the flight time, as it takes a lot more power to speed up the slowed down rotor head than to arrest the slowing down tendency during high loading situation. Just like it's easier to push a car when it's already in motion than putting it into motion....

I agree on all points except the voltage cutoff. I run mine at 1 (which is the highest level of protection) and have not had any issues at all during tick tocs or fast climbouts. In my experience setting it even at 2, which is the default, will drain your packs to the point that some chargers won't charge them at 1C until you put a little "juice" back in at low levels first. I found that out the hard way...

Glad you found this post helpful! Have fun...

I basically know how to program this ESC for quite some time. I've been flying electrics for over a year now.

It just caught my attention. And I find that you did a good job in explaining it. You should be proud....

There's been a lot of comments in the past about this ESC not being able to perform well in governor mode. So when I saw the last post in this thread. I just felt I have to supplement it a little bit for I am realy satisfied with this ESC's ability to perform in governor mode.

Governor?
What does the governor do?

I got this on a different thread:

If you try to program real throttle curves with the governor mode, you confuse the ESC and it may not respond properly. (Take it from someone who learned the hard way.)

Governor mode doesn't use conventional curve. All points will have the same value. You have to use the throtle hold switch to stop the motor. I advice you don't mess with this unless you have someone with you who knows what his doing. You seem have no idea as the one who posted that comment.....

ALIGN ESC ( RCE-BL25G ) Governor - good or bad ?
I have an ALIGN ESC ( RCE-BL25G ) to be exact and the align 3550kV motor.
I programmed the ESC last night to be (Heli/soft start with gov) which was putting the throttle at 100% position during the the 4th series of beeps. The heli flew like normal and I didn't notice any difference. I didn't need throttle cut switch to slow it down or stop it...are you describing a different model/set up?

Isn't the gov just keeping a motor a constant speed at any given throttle position? i.e. More throttle = higher rpm for 'that position' and maintains it at that speed regardless of the atmospheric or pitch changes it experiences?

Would selecting 'Gov' be more efficient (like cruise control or 'easier to push a car that is already moving, so less energy expended' and therefore longer flight times? or because it keeps RPM constant, less efficient since it drains the battery and heats it up because it will force the motor to a set RPM level?

I don't do 3D, just want a smooth ride and long flight time

Thank you for the help!
