I just set my 700x to gov store and left the rest all defaults​. I was wondering how I determine my head speed from the info it gave me. It said 114*1000 rpm. Or is that the maximum rpm it can do and I have to set head speed in my tx?

I thought the HS was set off your throttle percentage like it is in the stock governor mode but I could be wrong. Anything in the manual about it?

FWIW there really is no need to use governor store mode unless you have drastically different age packs. If you do use it just remember to set the HS using your WEAKEST pack.

It's a new pack. A pulse 5000 12s. I've herd it just keeps your HS maintained better.

That's what a governor does.... but what Richard is saying is that the battery condition plays a role in how well the gov is going to perform overall.....

Been there, done that and old enough to know better.....

Ok. So does anyone know what 114*1000 means?

Does the program box allow you to scroll through different settings for that MAX RPM setting ??

After doing a little "light reading" I "think" it might mean 114 X 1000 = 114,000 RPM ( max motor RPM )

Please note that I'm just guessing...... I have no experience with this programmer.....

Ok. I don't think it has a option to adjust it. I must have to adjust it in the tx. That's a lot of max rpm lol. Just don't seem real

Your motor starts to spool up at 45% transmitter throttle.

Consider using the following throttle curves:

NORMAL (minimum head speed)
0-50-50-50-50

IDLE 1 (halfway point to nxt headspeed)
65-65-65-65-65

IDLE 2 (max head speed with ample head room for governor)
80-80-80-80-80

90% throttle is the maximum recommended for very short flights

Voltage range is:
(12S x 3.7V = 44.4V)
Nominal for calculation purpose, under load and almost end of flight

(12S x 4.17V = 50V)
Freshly charged voltage at rest, no load.

Formula is
Motor KV (490) x Voltage In (*44.4V or 50V) x motor efficiency (.9 for 90%) x motor pinion (13T) ÷ Main Gear (110T)

Using 44.4V you will get 2324RPM and for 50V 2,605RPM at maximum throttle.

Adjust throttle curve idle 1 and 2 to your liking.

Optionally you can also use all 50 in NORMAL mode forcing you to use throttle hold as your 0 throtle position = motor off.
This alows you to do 3D in that flight mode without any worries of motor shutting off when inverted and stick goes below 25% position.

Consider that anything over 1800RPM in a 700 class is an absolute waste of "flight time" but given the nature of DFC and hard dampeners, higher RPM seems to be the norm.

There is a formula in the ESC manual page 10 where:
RPM ÷ Motor Pole ÷ 2 ÷ Gear Ratio × Throtle %

I was getting 2834 and 3191 which seems just to high. I dont think the blade bolts can handle those rpm numbers.

Hopefully someone else can make sense of that.

Best of luck!

Pistol_pete. Thank you for that. I only have a dx7s so only have 1 idle up. Should I put what you gave me for idle 2 for idle 1? And also just run 85.83.80.83.85 for my throttle curve. That get it around 1800 HS or so?

Personally I would just not use IDLE 2 numbers at all. Those numbers are for the noon event shows by the pros and a pro I'm not.

Start with the 50 in NORM and 65 in IDLE 1.

IDLE 1 can be all 55 if 65 is not your cup of tea.

You will not get 1800RPM with 12S. For that you need to go with lower cell count given the nature of the beast.(gear ratio)

Enjoy!

Ok cool. I'll try, I do mild slow 3d anyways. Thanks for your input
I've been getting 6min flight time with that throttle curve I gave you earlier. And lipo would be around 28% left

No, it needs to be a flat line or the governor will get confused.

Get yourself some 5s 6000mah packs and run 10s at 1800-2000 head speed. You will get another 3 minutes or so flight time, no extra weight (maybe even lighter) and no noticeable power difference!

I used to curse Align for offering heli's geared for ridiculous head speeds and no adjustable motor mount to change gearing but since they have gotten seriously ridiculous with the head speeds all you need is to run 2 different voltages and you can go from mild to wild with the change of a pack!

I have a hobbywing 50 amp platinum v3 and an ikon v1 in my oxy3.

I believe I have all the governor settings right. But this will be the first time I've used the governer settings in the ikon.

What is the best way to test my headspeed?

All blades off, strapped down?

I'm nervous about just test flying it, because bad governer settings can cause issues for the gyro sensors. But on the other hand, by strapping it down and testing it with the blades off the only thing i can verify is that it is reaching the correct headspeed.

And yes I know at a sport/ light 3d level I probably don't need to worry about the governer. I'm trying to learn, because I'm hearing good things about hobbywing and I plan to throw one in my Goblin before too long.

I will be doing the same thing but keeping the Governor at default Elf mode,I do not have the programming box so the Governor will not be stored,will be trying mine out with the head loaders.

I think I got it figured out on mine.

The ESC needs to be set to heli / no governer, and then Ikon handles the head speed.
But this is dependent on your gear ratios being set right in the ikon, and selecting the correct motor divisor (this is 1/2) of the pole count.

I personally hate governors unless on a nitro. They just add unnecessary complication. I've gone back to running straight 100% throttle with the correct gearing. I get more predictable pitch response (like a nitro), a happier less twitchy tail (and on the helis!) and cooler running motor, esc and batteries!

Once I realized I was running two governers and I turned the ESC's built in one off it couldn't have been easier. The hardest thing was looking to see how many poles my motor was.

Solid consistency through the whole pack. Not a hint of dip at the end. Now to be fair, this is partially due to a good battery. I went with the recommended 4 minute timer and it just feels so solid that I can't even tell the end is coming.
