Help please setting up Brain Governor

[Storrm]

Hi guys

I need help/guidance setting up my Brain for Governor mode in my Trex 550e. I'm running a 600mx (6 poles), Align RCE-BL70G ESC, 11t slant motor pinion, 112t slant main gear and a Hobbywing brushless sensor wired into the motor red/black wires.

1. Do I need to reprogram the ESC? It's set to soft start, no governor. It's a basic Unit and there's not many options to set
2. I've set the sensing divider to 3 according to the instructions (number of poles /2). This seems a little low so can someone confirm this is correct for a 600mx
3. How do I establish the correct throttle min and throttle max settings in the advanced setup menu?
4. What head speeds should I use? Is there a formula to work out the most optimum head speeds I should program the governor for?

Advice welcome
Matt

Pole count is 10 on the 600mx so sensing divider is 5 in the brain , set your ratio with the pinion an main gear calculator in the brain , your esc needs to be left in non gov mode an the brain will take care of the rest , first set your endpoints for throttle in the brain transmitter menu so you have 100 top an bottom then do your esc endpoints , now leave a linear line in normal blades off and keep tapping the plus value at bottom stick untill it spools an then drop it 2 clicks , now throttle flat out an go up on the plus untill you cannot get anymore rpm from your motor , when this is done you set the 30 60 100 flat lines an now enable gov in the banks , also in the advanced settings tick electric motor being used .

Now why couldn't the brain designers explain things as simple as that. Cheers bud, I'll have a play (blades off of course!!) and see where I get to. I have to say I'm really impressed with this brain. Totally stock settings from the wizard menu and my 550e flys extremely well. Just a little tail washout on hard pumps but I've yet to enable precomp.

*edit* are you sure about the pole count in the 600MX? I checked on a number of sites and 6 kept coming up. Guess I could always count them anyway :-)

Cheers guys. All running sweet now. Just need to work out how to make it soft start though as the spool up settings don't seem to make a jot of difference! The ESC doesnt have many options so (on taking some advice) I switched it into Plane mode to disable the soft-start. It works fine as long as I'm gentle on the throttle, so I'm hoping I can smooth it out. I've still not pulled my motor to count the poles, but having set it to 5 (10 pole) the head speed was faster than I expected. Setting it to 3 (6 pole) as per the Align specs, the head RPM shown in the Brain software from the RPM sensor was on the nail. not saying you are wrong, but thought I'd mention it in case you wanted to double check :-)

Thanks again for the advice and quick answers :-)

Soft start in the Brain is controlled within the advanced menu. Set spool up ramp to 1. That should sort it. Consider changing timeout to 30 or 60 if you ever intend to use bailout.

On your esc ensure soft start is not enabled or it will likely confuse the Brain, although some have found success in using a mix of etc and Brain soft starts. Worth experimenting to find preferred spool up I think.

I googled your pole count when you asked an half the threads said 10 an others said 6 , best to check the align website spec as I run scorpion and cudnt be exact, gov gain is set at 50 standard in the brain , up that to 60 65 an it will never miss a beat!
