Default Which governor?

Given the choice of using the hobbying 60A V4 built in governor, or the Microbeast+ governor (taking RPM input from HW), which would be the better option?
Logic would suggest that the FBL has more info than the ESC does (such as knowing when you increase pitch) to properly keep the headspeed constant, but I have no experience with governors, so what do you think?

You're right, the conventional wisdom says that the FBL governor is generally going to be better because it is preemptive rather than reactive. However, the HW V4's do not play nice with external governors (see 'Hard Start' problem). There are ways around it by using heli-linear mode and switching off the AFW in the ESC but I found it easier and more effective to use the ESC governor as the HW governors are pretty good.

All my heli's use the FBL governor except the one that has a HW V4 ESC.

I am using govenor for the first time. HW 60v4 on my 470L with a brain2 fbl.
I am using the FBL gov simply because I figure you only need to make changes at one place. Regarding the proactive responce using the fbl gov, with the processing speed of the esc I don't know if you would actualy notice the difference, but electronicly it would be faster and I would guess you are talking milli seconds.
But as I said, I don't have any previous experience so what do I know.

The theory is that the ESC only knows when the head speed has already changed and can correct for it. The FBL knows that you are asking to increase or decrease the load and applies the power change required. If the system worked perfectly the head speed would not change at all with an FBL governor whereas with the ESC governor, it would change and then get corrected.

In reality, some ESC's work better than others and some FBL's work better than others. Nothing is perfect.

Yup but then your pissing with FBL Gov settings to get it tuned properly to prevent bogging or over shoot. The V4 60 on that bird works great, plug in the LCD box at the field and tune the P and I gains the V3 doesn't have no PC needed and fly. Want to change head speed, land, change curves and fly, no PC needed.
Se so many vids using FBL gov having bogging and then mentioning having to link back up and do more tuning.

Yeah, I kind of agree. In my experience ESC governors pretty much work straight out of the box, FBL governors need to be tuned but are often better if you can be bothered to get them right.

I don't really have an issue with tweaking FBL governors because I use FBL's that are integrated with the Jeti so it's actually easier to tweak the FBL than the ESC which usually needs a PC or a box. If you don't use an integrated system, yeah, it's a pain.

Yup, you got a Jeti, the average joe goes to the field and flies and has to take a lappy and tweak for several flights. Basic V4 setup takes little adjustment if your paying attention. First 2 packs and done. Got the V3 and the gov S**ks.

I recently switched from the v-bar governor to the stored governor function in the 60A V4 and the model flies just the same.

The electronics are so good that it probably takes no time at all to work out the rpm is dropping in the ESC.

Did the same also, had Vbar, it did take some tweaking. Had overshoot once then tail wag, etc. Yup the V4 electronics have a faster CPU etc. and works better than the older versions. Went to all V4s and no more wasted time.

Running ikon 2 gov, works great with 60A v4. If you have logging makes it a breeze to tune.

Same here, using Brain 2 gov. Was extremely easy to set up. It even shows you what rpm you are running. No guess work, no need to use a tachometer or a head speed app.
