The reason you want to run governor mode is to have constant rpm while changing pitch angle of the blade. The ESC will take care of the HS as much as it could. The ESC will see the throtle percentage as the intended target HS, that is why flat all accross is needed. And as long as it sees, lets say 75%, it will try to maintain the HS attained at that percentage the best it could. If it sees ever changing throtle percentage, it won't be able to stablish a baseline HS. That's why I adviced you earlier not to mess with it unless you have someone to help you. And arming the ESC require the TX in throtle hold, which is 0% Throtle, so the ESC knows it's not time to spool up yet.

BTW with that 25A ESC of yours, that motor need 11T pinion, if you'll ever gonna make that ESC motor combination to work.....

If I were to be ask if governor mode is more efficient. Based on my experience I would say yes. But you have to have the right combination put together......

I "had" mine set up the same way with high voltage protection.

I was doing a hard bank turn and then the 450se just "dropped" from about 30 feet

Blades shatters, lost landing gear and bent main shaft. (25 bucks of parts, no big deal)

but the 35A align ESC was non responsive when I plugged it in, no beeps at all anymore, applying throttle just made motor do little blips like it was trying to spin up over and over.

I am thinking I had a Bad ESC, but there is no way to be sure.

It was a full pack too.

*if* it sensed a voltage cutoff and enabled protection, I dont like the fact it just shuts off the power completelty. Why cant it just reduce the power so one can recover from a crash potential ??

I am also wondering if it over heated, its sits under the base frame with heat sink facing the ground.

I need to get another ESC, but am not sure if I should get another RCE-BL35G

It sounds like something else may have happened. I can always tell when my battery starts to get low even before the ESC batt protection kicks in, because the power starts to drop beforehand. I also use an audible timer on my tx to help me keep track. You may be right... your ESC may have crapped out on you suddenly...

This is my set up. I'm running 430XL now @ 3000rpm.

brakes off *
high timing ***
low voltage cuto off ***
governor mode ***
quick response ***

85% throtle straight accross. 4min flight time, stick banging. 5 min make the lipo hotter.

I don't think your ESC is broke. Before you plug the battery switch your throtle hold "on". The ESC wont initialize until it reads 0% throtle. When your ready to fly, switch the throtle hold "off", and the heli will start to spool up. Once you landed switch the throtle hold "on again to stop the motor. That's how governor mode works

Do you think high timing and gov mode would be the best setting for a 430L, as opposed to your 430XL?

I did it both on my L and XL motor. Best for both motor IMO....

Does anyone know of a way to wire a L E D into the programer to help with setup? With my bad hearing, there are no beeps. I have a new Trex, but don't know if I will be able to even do the set up. Don't know anyone around here that can help.

I just found out, atv on radio don't match the esc's

By accident, I found out the ATV on the radio have more resolution that the Align's ESC.

I plugged the battery pack when I haven't engaged throtle hold yet (my ESC BTW was set to Gov mode, Throtle dialed 83% straight across). The ESC went to programming mode.......

So I revert it back to aircraft mode and played with it for a bit (I have the all the blades removed from the machine while doing this). The ESC was going full power just right pass 3/4 stick high and disengaging at 1/4 stick low. So I had the ATV's adjusted 80% on the high stick travel and also 80% on the low stick travel...... Also the subtrim down 6 points (reason being, I want both ends of the ATV's equal on both sides).

Now the ESC is in full power, only at full high, and disengage the motor at full low. So in governor mode the %'age on the throttle curve really match what the ESC reads......

THANKS A TON!!! this is exactly the step by step that I was looking for, bought the heli setup from a "pro" and he didnt get me any documentation for the heli (threw in a SE book ), or the ESC !! __ Question how do you know how or what to set the motor timing to, and what does it effect?

this is a tricky one........

there's certain guideline I do abide by.....

Timing settings depends on wether the motor is an inrunner or outrunner.....

Number of poles also play a role......

So also does the kv of the motor......

Inrunner motor usually have low pole count than out runner motor.....

2-6 pole generally can be considered low pole count.... More than that usually can be considered high pole count.....

Low pole count generally require low to medium timing.... high pole count requires high timing......

exception to the rules...... Low pole count with high kv rating will need high timing to operate efficiently with power...... Low pole count motor with not high a kv rating but being spun very high using high cell count battery packs will need high timing to operate efficiently with power......

some motors comes with instruction telling what timing exactly is needed...... some doesn't, so, you gonna have to experiment with the settings..... This will require that e-logger and/or data analyzer be used during testings......

wow- now I am kinda sorry I asked that's a lot of information to try to decode...I dont really understand brushless motors that well, pole count, KW ratings, etc. All I know is that I buy them, plug them in, and they run. That's going to be my next learning endeavor. So _ now that's answered question #2 -- I flew my Trex a few times, then it sat for (a day?) and the ESC magically lost it's programming... What would cause that? I don't think that it was something I did (if it was obviously I didn't do it on purpose). I did get it re programmed and it flies just as good as it did before, just wondering why the thing decided to lose it's brain. And, thanks for explaining the pole thing, it doesn't make sense to me now, but I am sure one day it will. Do you have a resource on brushless motors that would explain KW, poles, etc. ?

Don't be intimmidated by the terms.... If you know what they mean, they are really simple....


Every motor have a rated rpm per volt applied. In kv, k is the rated constant for a particular motor, an rpm constant per volt applied(lets say, a 3550kv motor, 3550 is the k of the motor then you multiply that with your battery voltage under load, to predict the rpm).....

Pole is the term used for the magnet and stator in the motor. The number of stator pole is usually match with same number of rotor magnet.... So, if you count the magnet that is the pole count.......

Now for your ESC's anomalies..... Several possible causes.... You may have powered the ESC with the throtle not in the full low position, That it entered programming mode, that you didn't noticed.... Another, the reciever was powered on before the TX got turned on, the case in which when the reciever initialized the ESC read a signal other than throtle fully off position....... Or, it could also be defect in the ESC itself......

That may explain a bit... So, when I bind my reciever to my TX, I ensure that the sicks are at "fail safe" position ( all down or neutral ) , maybe I left one of the sticks up one time and just didn't notice it. Is this a problem when you put the RX in bind mode ? I thought it shut off all output from the RX when you put the bind plug in. As the battery plugs into the ESC, however could it pick up a power from that and do it's own thing?

I am able to get to programing mode just fine, but my ESC (X model) doesn't announce what the current settings are. If I start it stick up it makes the chime, but it doesn't beep the current settings, then I go to stick low and it starts though the sequence. Anyone know what is going on here?

You might need to reverse the throtle channel....

I figured it out... On mine you need to start with throttle down for it to repeat the settings.

Another problem I'm running into is the esc thinks the battery is low on all 3 of my TP2070 batteries. I am pretty sure the batteries are good, but I'm going to get a data logger to figure it out.

thanks

I bought my align 35a esc on ebay an didn't come with instructions. Thanks so much!!
