Throttle setup with Align gov

[bacala600]

Hey guys, I was planning on my first flight with my 600n this weekend, I'm just trying to figure out a good setup for my throttle curve. In a previous thread I learned how to achieve 3 different head speeds using program mixes with a DX7 and Align gov, my question is how should the throttle curve be set when using a gov, should I use a U shaped curve eg.(100,60,50,60,100) or rely on the gov to maintain the desired head speed and setup at 100% at all 5 points in idle mode, I will be using the Align pipe and OS hyper 50 running 30% nitro fuel.
What suggestions do you have for me, what has been working for you Thanks.

Im sure you will get more people behind me with detailed help, but you will want to you use a throttle curve while in conjunction of your Governor in case of failure or radio settings that didn't save etc etc. Also your definitely not going to want a %100 curve again for the same reason, but this time you can end up hurting your own equipment running %100 throttle and almost zero load on the head should you governor have a problem. My best advice to you is to setup you radio with throttle curves like you would if you would not be using a governor 0-100 for (Hover Up) and then your desired V or U curve for you Idle up flights.

I hope someone else chimes in I have the same setup and I can find easy setup, Im about
to just go gov on off with aux switch, I wanted to know if when your setting it up all the posts
say in rate of mix2 set headspeed desired per the manual that came with the gov,
do you also set the other side? Mine is not working and Im tired of reading.
When I flip aux2 switch the cursor goes to the -- line below rate???

Jbock24.....
I'm not sure that I understand your post.... Please try explaining your problem again...

Bacala600....
You really shouldn't run a gov until after the engine has gone through the break-in process. And during the break-in is when you should be setting up your throttle curves for your flying style. Once your engine has been broken-in and tuned properly, then you set-up your gov speeds.

The reasoning behind this is two-fold.... First, a governor can, and will, mask a pooly tuned engine and can cause engine damage. And two... You really want to have good curves programmed in to the TX incase you have a governor failure, or throw a magnet, or a sensor fails, ect.....

ok if you turn on your dx7 and go into programming, when looking at program mix
it looks like {prog.Mix 2}
Aux2: Aux2 on
Rate 0
> +80
SW:F-F-S12
offset 0
when I flip aux2 switch to 1 (or gov on)
the arrow points to +80 When aux2 is up and gov off the arrow points to 0
Is this correct or do I have something wrong

[jbock24]

I think what Im trying to say is the arrow points to the headspeed you have set in +
should there be a percentage below it or above it if your servo is reversed, mine is not
or should it be zero, I have throttle curve set for 0-25-50-75-100 it runs perfectly with gov off
when I have it on and spool up its shakey when set as low as 65. Should I get into a hover first and be prepaired for a fly away if set up is off, kinda dont want to do that.

[george0079]

the prog mix is correct.
And, another way to do it, for a single head speed, that may be easier...
Travel adjust menu
Aux2 +90% ......... Equals 80% gov on
-150% ........ Equals gov off
And reverse the channel if the switch is backwards.

What do you mean by shakey?

Your pmix is correct. The issues that you're having are something else...

[jbock24]

well its fine and when I flip to governor on before it gets spooled up the tail has a intermitent
shake not really a wag has 401 on it and stable, Ive had belt issues had to tighten or loosen depending on temp its been 20 here one day and 65 the next.

I might do this till I get it sorted just set up one switch aux 2 on/off

[bacala600]

Thanks for the help george0079 that's what I'll do leave the gov off for now and setup without it, also can anyone tell me if the following setup would be a good start
Pitch Curves
Nor low-5, mid0, high+13
idle1 low-13, mid0, high+13
idle2 same
Throttle curves
Nor 0,30,50,70,90
idle1 90,70,50,70,90
idle2 100,80,60,80,100
This is only a starting point I'll be using, does this seem alright, is their any changes I should make, Thanks.

Hi Bacala600,

They are almost identical to the setup that I flew last year, except that I put 100% on the Idle up 1 endpoints. (I like having full power for full pitch climbouts.) But you should be fine with the those.

Keep 'em flying.:YeaBaby:

Can someone please exaplin to me what the offset in the dx7 prog mix1 menu actually is.

I have just done the same setup and am running one headspeed in all flight modes through the +endpoint of the aux2 channel.



I tried to copy something similar to the ATG setup but ran into several problems.
Changed root menu to be AUX2>F.MOD
Set atv aux2 +68 approx 1700 -90 approx 2000
Prog mix 1 AUX2->AUX2, rate +105% 0%, SW F-S12, OFFSET -100


The 105 was just an estimate going by a mates ATG and the offset was just matching finless ATG video.
NORM >green light >govenor on
IDLE1>green ligtt>governor on
IDLE2>red light govenor off

If i adjusted the offset down to -6 then IDLE 1 changed to red light. Then adjusting the + side of the aux2 channel moved the point at which the offset turned off the govenor.



Sorry for the long winded post but i couldnt find an answer. Hope you guys can help.

Thanks
