View Full Version : Are pitch curves personal?

Folks,
In other words, should one set it by the book or by personal feel?
If one wants to fly stunt mode 1 at 80%, why should hover point be over half stick?
Why could it not be like normal mode, hover at half stick? The rest of the range to follow both positive and negative.
Advice appreciated.

Yes, pitch curves are a personal thing. As long as you know what your trying to accomplish then set it however you like. Only thing is you should warn someone if you ever let them fly your heli.

most of the guys I fly with use linear pitch curves with no expo. Don't know if that is mostly true for the majority though.

Great, That makes is a lot more comfortable for me.
Thanks

If you're doing even simple aerobatics like stall turns, you need to be able to find mid-pitch easily.
If you progress to inverted stall turns, then it probably simplifies matters to have things symmetrical, but as others have said - no reason you can't adjust your pitches to your own preferences.

Tried flying one stunt mode as per mikados instructions.
Using 80% power on linear curve.
I was impressed. I think I might want to switch the normal curve to linear.
Would there be a problem doing this?
Personally I never fly in 'normal'. I learned to hover in it and I think it worked well because it gave me a bit of sensitivity in terms of pitch, at a point in time when I needed it. When I started FFF I learned that it didn't work all that well, because it was difficult to descend without losing headspeed. So I started to use a mix of normal/stunt modes depending on what I was doing.
So I started to learn to do FFF, and sooner or later I got to a stage where I wanted to try a roll. I did one, and it was OK. So I did another, and it was better. So I landed and had a breather, then tried again.
When I got inverted, I added negative collective, and the motor stopped. I realised what was happening but with a 450, things happen fast and it was too late to do anything. It wasn't too bad, but it would have ruined my week if I'd done it with the 600.
Since then I've heard of dozens of people who've done the same. I'm also annoyed with myself because I saw that one coming, but still fell victim. So my view is that as soon as you start FFF you should start to use stunt mode, and use it all the time so you don't get confused, as I did. And land by hovering at about 1M then killing the motor - try to hold it off of the ground as long as possible without ever letting the helicopter rise. It's not nice to have all that headspeed so close to the ground.
I think using several modes to fly in should really be classed as 'advanced' - as in f3c or similar, rather than for beginners.

Hey,
Well, I'm still learning. But I must say that Im very comfortable with the mikado 600 3d fly bar version.I finally got her reasonably dialed in. Did some stall turns and rolling stall turns today. Found her a bit sluggish on the roll. I'm using the 60%set up on aileron, elevator and pitch.
If I wanted her to be a bit more responsive would you recommend increasing the roll rate on the swash settings?
Kindly let me know
Thanks

Hey, we're all still learning. I'm not hugely advanced and do no 3d. I'm taking things very easy; currently working on backwards flight and autorotations on my 450 but nothing inverted.
Hope you don't mind me giving advice, but I figure it's often more pertinent when it comes from someone who's at around the same level, but perhaps just a little more advanced. My mistakes are closer and fresher in my memory.
My 3 thoughts are...
expo (? too much - makes the heli seem less responsive, though max. roll rate unaffected)
headspeed (? too little)
possibly the % rate on the swash settings. I don't know the figure by heart. Do you have a pitch guage and can you measure how much cyclic pitch you have?

Hey,
No expo, not sure what the head speed is but using gear 4216. Will chech head speed tomorrow. Have pitch gauge but never used it to measure cyclic.
How does one do that?and what should I be looking for?

Their is a minimum to respect but for the most part pitch curves are personal.
