Setting Head Gyro for Scale setup

[MarkH]

I'm finishing up a scale help and have a question on the final Horizon setting. I did the test flying and settled on a Rigid Head Gyro default of 60. Although I don't need the collective pitch action of CR, I was hoping to set a higher Horizon self leveling in case of temporary disorientation just to level things out. On tab7, after selecting Horizon, then Hover & Scale, what should I set my radio up to do?



What I have done is, on the Diagnose tab, set my Trainer switch so that in the Normal position, my HOR Channel show 60 and if I activate my TRN switch, my setting goes to 85. My Head Gyro setting stays at 60.



Does this sound correct?



Thanks,

Mark

This means that you are constantly flying with 60% horizon gain, and increase it to 85% when button is pushed. That does not make real sense, as the difference in gain is not that dramatic.

Suggestion, if you want to go this way: Trainer switch in normal position should have a 0% signal (center) on the Horizon mode. This means you are on yourself, no horizon active during flying. Unless you need the horizon to level the heli and push the Trainer button, then it should move to whatever value you like: 60-80% sounds good.

Joachim,

Thank you, that makes sense. I'll try that. I know that BD is very popular in Europe with the scale fliers. Do you know if "Horizon - Hover & Scale" is how most scale guys set up their large helis or are they just running Rigid?

That's how I have mine set. A two position switch with pos 0 having 0 gain for reg (no self level) mode, and then 60% for horizon self level. Im a newbie and my bd3sx has been great on my 550 pro dfc--so stable even when its not in horizon mode----

I've been using VBar for the last 6-7 years so a little bit of a learning curve.

Thanks.

I would be interested in your reason for the switch to BD.

Yes, that's the only mode allowed for a not symmetric collective curve. Usually you have hover pitch at mid stick set to 4-6° on scale machines. With this, the rescue mode options are not allowed to be used!
If one wants to run rigid mode only, get a 3X. No need for a 3SX, as the horizon and rescue options are the "only" difference.

Got into Logos and VBar was my first FBL experience after ditching the flybar (FYI, started with piezos in '95). I was very happy with everything about VBar until the Neo & vcontrol. The single line, xbus in my case, restriction and governor setup ( which now goes through Neo ) took a lot of the flexibility away.

I'm only building large scale stuff now and know a majority of the scale guys in Europe all use BD. Plus, I previously did one BD setup but it was a fairly simple one and I did not fully understand the process.

Joachim,
Danke für Ihre Hilfe. Meine Mutter ist Deutsche und ich lebte dort bis zum Alter von 6. Ich bin 51 und wir immer noch meine sehr großen deutschen Familie alle 2 Jahre gehen besuchen. Es ist eine kleine Stadt, die von Trier an der Mosel.

thanks, danke.

[DEMONjoe]

Thanks for the info.

Und viel Spaß beim nächsten Besuch in Deutschland. Trier ist leider recht weit (für deutsche Verhältnisse, 300mi) von hier, sonst hätte ich Dich auf einen Stop eingeladen
Will be at Joe Nall and IRCHA though.

Hi Joachim, I'm not quite following you on this one? I set up my 600 esp to fly with pitch curve set at 5° at mid stick and have been using rescue on my 3SX. It seems to be working as I test it while hovering. Haven't had to use it for a crash yet, knock on wood. I'm now building my 2nd 600 esp for AS350 scale with 3 blade scale starflex head. So looking through BD threads to see if set up will be any different from my 2 blade 600 and came across this post. Thanks for your help as always. Terry
