Hey Guys I have been having this issue now consistently with my Trex 600. It has a Caste Creations ICE2 HV80 in it and I am running in governor mode set RPM. The idle up 2 is set at 2245. When I do any sort of hard collective ascent or descent at the end the head speed with drop considerably and then regain. Is this a gain setting the in ESC?? Thanks for any help Ill post pics of my set up as well.

So, the headspeed holds during the ascent or descent?

Correct, then as soon as I let off, the headspeed drops dramatically

Most likely your "head speed change rate" setting.

Thanks so much John, ya i went by those settings on my setup, granted my Trex 600 is the newer one with the 750mx motor and 118t main gear, so the ration and power is def different, not sure if that would effect anything. here is my settings:

I would then set the governor gain higher.

Have you checked the logged data for additional input such as battery ripple??

I can, what should I be looking for and if you don't mind, what is battery ripple? Thanks

I would say lower governor gain because what is happening is the governor is trying to shut the throttle off too much during an unloaded situation.

I would also try increase the HS to around 2350 (don't worry if you get a governor warning). You said 118T main gear but the new DFC Pro has a 112T main gear and 13T pinion with the 750MX 530kv motor.

Ah yes just noticed you have the gov gain at 25 and castle recommends 15 with the old 600MX motor, the new larger motor will require a lower gain setting anyway.

60% of the time, it works every time!

THanks Richnmond, that makes I will try lowering the gain today, and turning up the HS a little.

Just to clarify my heli has a 14 pinion and a 118t Main gear and yes the 750MX motor, so the settings are most likely a little different for this beast than the typical one with the older gearing and 600MX motor .

In that case yours is even higher geared than the stock pro dfc so I would definitely increase the hs.

You may also want to check the setting recommendations from castle for the 700 class for comparrison given motor used.

Battery ripple = voltage stability.
Used to help you determine when to replace batts or if batts used are up to the systems demands. Avg is less than 5% with peaks less than 10%. Percentages calculated from the nominal voltage of 3.7V per cell.

Thanks your right, I checked the Castle site and found recommended setting for the 700MX, not the 750, but non the less, the gain settings are lower.

One question visually waht would indicate "ripple" when I am looking at the castle log and what should i be looking for
