I'll soon experiment with governors.

for now, Im ok with the transmitter throttle settings.

Especially until I get the feel for these new birds.

So in all my models I have the Governor mode off in the Castle ESC's.

What Im shooting for is a fairly low head speed in normal mode for taking off and landing... easy forward flight, and for longer flights.

Ideally stunt 2 would be about the most aggressive head speed I would want maybe 2100 RPM pr so on the 700 plus models.
and Stunt 1 somewhere in the middle.

So
what is common to see in each of the throttle curves? Normal mode, stunt 1 and stunt 2?

or I guess I should say, based on my description, where should I put mine?

thanks ahead guys.

If you have too much HS range, you need active freewheeling which Castle does not have.
If you want something 1400 as normal and 2100 in IU2, your gearing will not be suited for 1400 and you will sacrifice flight time and maybe even the ESC.

I don't know why you wouldn't use the GOV especially if you already have one. Once I switched over to a GOV, I never looked back.

If you want to continue on, you have to set the throttle curves with a tach and just adjust until it does what you want.

We'll it obviously depends on the setup but if we are talking typical Align setups you would want around 70% in normal, 80% in iu1 and 90% in iu2.

You always want a steep ramp up from point 0 to point 2 on your throttle curve in normal mode. For example 0-60-70-73-75.

For iu I personally like flat throttle curves, the tail behaves much better. I will occasionally use a slight V with no more than 10% between mid stick and high/low stick. For example for iu1, 85-80-75-80-85 or 80% flat. I may also use around 10% cyclic to throttle mixing.

Ideally for me I like 100% flat if not using a governor which I like to do on anything below a 550 size heli. For most Aligns though that is a pretty screaming head speed so be careful.

60% of the time, it works every time!

700 headspeeds

Use your governor.

And 1600 rpm for normal, 1950 for IU1 is plenty of pop for most people. That's a big disc and carries a lot of energy.

Unless you are a Smack pilot you don't need 2100-2200 rpm to fly mild 3D and have reserve power to punch out if you make a mistake.

"You always want a steep ramp up from point 0 to point 2 on your throttle curve in normal mode. For example 0-60-70-73-75."

I agree with a steep ramp up in normal mode but I've never understood why you would want a continuously increasing throttle. For me the only reason I see to have a normal curve is to go to 0 throttle at 0 stick; other than that it seems to me the curve should maintain constant throttle, e.g., 0-70-70-70-70. I'm only talking electric here. What am I missing?

If you are using a Castle, that is how you setup for the governor.

I could see using curves and a smooth ramp for a nitro, but not needed on and E-model.

He should spend a few minutes and learn about governors and never look back. Setup a normal curve it he has to tune a nitro or wants slow spoolup with an electric.

Just my opinion.

Aight then. Maybe I'll just get Into governors and quit putting it off.

So on a 700 let's say goblin 1750-1950 head speeds.

770 slightly lower right ?

I thought the throttle should remain constant,whats the point of having a slight dip in the middle of the curve in idle up,is that suppose to prevent over speeding.

That I get, at least for nitro. As you move towards 0 pitch you are likely unloading the head so yes the engine will overspeed. On my electrics though if I don't use a governor I use flat curves. That said, I use a governor unless I'm troubleshooting.

My electrics usually are 0-85-85-85-85 for normal, a flat 85 for IU1, and IU2 is a flat 95. Seems to work out well.

My throttle curve suggestion for normal is actually exponentially decreasing, the heli will not leave the ground till after half stick and I only suggested a 5% increase from there to full stick. The OP only wants normal for take off and landing anyway. But yes 0-70-70-70-70 works fine also.

You've answered your own question there!

About your over speed question, yes a V curve will mean that while doing a relatively slow decent with some negative pitch will mean the headspeed will increase slightly. However during mild 3D, tick tocks etc. the headspeed will be slightly more consistant. That's where governors are better, you get the best of both worlds.

I personally like the slight over speeding, you can use it to get more 'pop', it's all about timing, this is also more how a nitro heli feels.

With a governor you get slightly less initial 'pop' but you get more acceleration and sustained power which actually makes them harder to get close to the ground with when showing off! This is why nitro's are better for that kind of flying (pop and lock!).

60% of the time, it works every time!

I fly *** NITRO ****

In norm mode I no gov set

IU1 - I have 1800 set in the MultiGov Pro

IU2 - I have 2100 set.

I do not have a set line set in IU1 and IU2 but use "V" curves in the Transmitter.

Let's see how others run their NITRO setup??

I fly nitros,
but I think the thread will become confusing if people start putting up nitro curves which are very different..

maybe start new thread ?

They don't in that they can't spin faster than their rpm per bolt but a nitro motor would keep getting faster and faster till it failed.

What I meant was the head speed would increase more than the head speed in a hover, not only from being unloaded but also because of the V curve.

Flat Curve

I run my 450 (flybared), with an 3800Kv motor, 9T gear, 315mm blades, Align BL35X ESC with a soft start and flat throttle curve on all modes. 0, 36.5, 72.5, 72.5, 72.5 . I sport fly no 3D. No complaints here.
