How to properly setup GOV_STORE?

[devilfish]

Why can't you just take off the pinion. And let the motor spool up to 100% on the bench..
Would be similar to take the main and tail blades off, no?

sure it would be.

That's how most do it. However only charge the flight pack to 4v per cell to retain accuracy.

Sorry but I gotta say
P
I am very confused.

One earlier post quotes Heino saying set gov store with blades on

Another post quotes Heino saying do it with blades off

And one post, only one I could find, saying most people remove the pinion when we setting gov store, but the first time that way of doing it is posted is FIVE pages into the thread. are most people really doing it that way? It's only mentioned once that I can find,,


Which is it really??

And why remove the pinion, why not just back the motor away for the main gear, leaving the pinion on spinning free???

So far I have seen at least three definitive posters saying their way works best.

I just want to know,,,,

I DO not want to spin my goblin up to 2600 rpm with blades on to set gov store,,,, so I favor the no blades, but pinion spinning the main gear, or even better, motor not even spinning main gear method

I wish the manual was more clear on this topic...

This thread, while sticky, is internally self contradicting, and therefore of little real use, or at least without a definitive answer on how to set gov store, in my opinion.

Ok, just set up two of these and the RPM was within 1 or 2% of Mr. Mel calculator and gov works perfectly.

Gov store
4.0v per cell
No blades (neither main or tail)
No backing off pinion, just let head spin.
Set 100% flat line and keep throttle hold on while ESC initializes for initial spool up.
I never got a good "kick" but could tell when rpm leveled off.
Shut all down, charge then go fly!

Trust me, it works perfect!

I did the same, but Mr. Mel's numbers are still off even after he changed them.

These numbers were taken using 4.0v, gov store option.

Mr. Mel:
65% 1996
85% 2238

Actual:
66% 1750
81% 2200

Mr. Mel's calc is good for reference, but not close. I have done it different ways and then input that method into MM's calc. Never has it been right....unfortunately.

Might be interesting to find out what transmitter MM is using, this is were the differences in % may be.

Yikes



Trust me it works perfect, within 1 or 2 percent of MrMel

And

Doesn't work, not at all close to MrMel

Something is really funky here

I'll try it, and if I am within 1 or 2 percent, I'll be ecstatic....

And if not then uneasy

I noticed that the configuration charts in the goblin manual were about 200 rpm lower than MrMel too ( when YGE ESC was listed) .. I wondered about that... That data probably done empirically,,,,

So I bought my pinion based on the manual, not on the head speed calc

About the transmitter MrMel uses...What transmitters are you two using? If they are the same, then what

Also, you both are setting endpoints before setting governor store?

Set end points before gov store. I am using an 8FG tx.

[taosgraveyard]

If end points are set, the ESC will see 100 percent on full throttle. If MrMel set his endpoints, transmitter type should not make a difference I would think...

I once messed up and set endpoints with the throttle trim bumped all the way up... It made zero throttle too high,,, that could make the ESC and the transmitter see 85 percent differently

But I bet your trim was cranked down

Trim is 0 and I'm using an 8FG as well. Mr Mels calc said I needed 68% and I actually needed 70%. Pretty darn close here! However, my Scorpion was off by 200 rpm.

Excellent video Mr. Mel, thanks!

[aviator493]

Great video! One question, though. If you do the stick method or card method with vbar, shouldn't you have it connected to the vbar esc channel? I ask because with a properly setup 8FG calibrated during vbar setup, you're endpoints are set usually at +-99% to give -100/+100 in the vbar. Basically, I'm asking if you can do it the way you just did as a vbar user?

Just FYI to anyone out there using Mr. Mel HS calculator, I found that setting up gov store at 4.0v per cell with main and tail blades off the Goblin produced best results. I can't remember if Mr. Mel had recommended blades on or off using reduced voltage setup. His calculator was within about 1-2% of my actual HS using stock 690 blades.

If you mean with VBar governor see my other video, if you mean Governor store with Vbar as "receiver" it does not matter really, but yes, do Vbar 100/100 is the "best", just in case you go VBar governor in the future.

[Helico-pteron]

I set end points using the card, not the way you show in the video, then programmed everything after that. Is this method ok or should I use your method?

Like I said in the video, there is two methods but YGE recommend using the sticks, so that's what I teach in the video, no difference in the end result so no need to re-do it.

Ok, great, thank you.

I have read the manual and watched Mr. Mel's excellent videos. I also read the information on Joe1l's information regarding PWM and timing. I made several errors and have tried several solutions with no luck. Problem is no head speed- around 1100 on X-7 with Scorpion 4035-500 with 11 tooth pinion. Radio is DX-18. I tried calibrating throttle end-points at 11ms and 22ms with same result. I am using programming card that may have been powered over 6 volts. I ran up the motor after each programming step and did not get the drop in voltage showing that it accepted the run-up.
1: When can I change back to faster frame rate?
2: I used 6 deg timing and need to change to 18 deg. Correct?
3: Can I use Governor and not Governor Store mode? If I continue to have problems with Governor Store, can I turn off the Governor and use curves?
4: Any other suggestions are appreciated. Mark

If I've already programmed Gov store and reconnect the program card later on to change other options, do I need to re-program gov store or will it save those settings?
