Not getting up on gov fast enough
Using a hobbywing 100 esc and ikon fbl, I'm using the fbl add the gov. When in normal mode it's having trouble spooling up and getting on gov fast enough before my pitch starts to lift me off. It causes the heli to stay too tip over. If I go into idle up on the ground, it'll go into gov just fine. Any ideas? What should my normal mode throttle curve be for using gov mode

Here's a suggestion,

Are you open to the idea of just using the hobby wing's GOV Store mode?
- excellent company and with your goblin 500
- you should be able to see 2500 to 2700 head speed easily.

* I assume you're using the V3, even if you're using the older versions, the internal governor works very good

HW V3 and Brain/iKon are a nice match on external governor. Have my ESC set to airplane mode. Spool up is very slow at default setting of 2 in iKon governor. It is much better set to 3. You can do this in the advanced settings governor tab, it is towards the bottom of the page. If the change to 3 is still to slow (should not be) you can also increase the ramp rate in the same advanced tab.

The one question I have is how you have your throttle/pitch set up were it wants to take off at such a low head speed. You should come out of throttle hold at zero pitch and then take off after head speed has come up on governor.

Try taking of the freewheeling function from the HobbyWibg 100v3

I looked over everything. The only thing I seen weird is my throttle curve in normal. I'm still getting used to my 18mz and adding in point curves so I think I had it messed up. It was 0...25...40 40 40 now I changed it to go 0...40 40 40 40. On the bench it starts it spool slow but send to get on gov quicker.

Have you thought about going straight 40% normal throttle curve and initiating spool up out of throttle hold? Let the fbl have full control of the spool, Brain/iKon does this very well.

Ya I thought about it but I don't feel safe doing that. I don't mind having the normal mode. I flew yesterday. Jumped my curve to 0..40.40.40.40. Gets on gov soon enough now.

I fly Spektrum equipment. I have throttle hold with three flight modes set up and also turned on the throttle cut function you would use for a nitro. This gives me a second throttle hold switch for added safety with my electrics. You can't accidentally spool up hitting just one switch. I would think Futaba would have this same functionality.
Set up this way you don't have to worry about pitch/throttle curve interaction during spool up.
