Align RCE-BL35g Governor mode
I have the T-Rex 450 SE V1, with the Align RCE-BL35G. I've been flying this for about a year now with the same settings as when I first set it up. This was the first helicopter I set up and it's served me fine until now. I've recently started getting a little bolder with my flying and I need to change the head speed. I have the ESC set to Governor mode, and I have the throttle curve for idle up set to a flat 75%.

According to my interpretation of the instructions for this ESC, the governor speed is set by the throttle setting, which in this case is 75%.

I'm a little bit confused, or uncertain at how exactly this governor works and would appreciate if any one could tell me in greater details how the governor interprets the throttle setting with the speed at which the governor actually attempts to maintain.

What I'm ultimately getting at is that I'd like to increase my head speed, but I don't want to waste battery power so I don't want my head speed increased at 0 degrees. Now it's obvious that I could set up a throttle curve in my radio to do this, but what I don't know is if this will bypass the governor? I'd like the governor to continue to do its thing.

Can anyone shed some light on this? Will using a throttle curve work with the governor?

Thanks.

I have not been able to get a gov mode to work well on any of my esc's. Your best bet is to use your throttle curve to set your head speed and let the radio do the rest. Forget about the gov mode. Just my 2 cents.BEAM TEAM USA

Well, to answer my own question, it APPEARS that when you setup a throttle curve to anything but flat, it APPEARS to bypass the governor.

However, i'm still not sure. I'm going to just set the flat throttle curve up to 85%. That seems that it'll obviously raise the rpm, so thats a good start even if I don't understand this governor.

Does anyone even run the governor on this ESC? Do most people skip the governor and just run a simple throttle curve?

So here's what I found out about the governor mode on the RCE-BL35G...

For the governor mode to actually engage, you have to send a constant throttle position to the ESC from the very begining. Meaning you can't start up and manually spool it up.

So there are two aspects here. First is setup. You need to configure your ESC for governor mode, and you have to setup your radio for governor mode. Second is correct usage. You need to engage your governor mode correctly.

1. Setup. First setup the Governor mode on the ESC. I won't get into general RCE-35g setup procedures, but the option number 4, aircraft mode, you need to set it to the high stick option, 3 beeps (Soft Start + Governor Mode).
Then you need to setup your transmitter so that it has a flat throttle curve. I set this up on my radio as idle-up 1, at 80% along all points in the curve.

2. Usage when ready to fly. For the governor mode to engage, you need to turn on your transmitter, put it in throttle hold, so no throttle is transmitted.
Then connect your battery to the ESC on your helicopter.
Then, while still in throttle hold, switch to your flat throttle curve, for me this means enter idle-up 1. Then when I'm ready to go, I flip the throttle hold switch, and the soft start gently spools up my helicopter, with the governor engaged.

If you start your helicopter any other way, the governor is bypassed. It seems that if the ESC recieves any throttle setting that changes at anytime while the motor is turning, the governor is bypassed.

I personally don't like not being able to spool up manually. I'll try this a few times and see if I can get over that.

I just purchased a T-Rex 250 and have really enjoyed flying in my living room during the cold winter months! My ESC is an RCE-BL15X and also had governor mode. Though I haven't engaged the governor yet I am researching its proper use.

Is it possible to spool up the helicopter in normal mode with a standard throttle curve in the radio (my governor doesn't engage in normal mode-only idle up 1 and 2) then switch over to idle up 1 with a constant 80% throttle curve? Will this cause the governor to disengage?
