Trottle curve vs Pitch curve

[Blackite207]

Hi Guys,
I am setting up my Shuttle Challenge with -2deg and +8deg cyclic pitch. I do not know what the trottle curve looks like nor pitch curve. A friend helped me the last time but i have not flown in many months and will be back to basics trying to remember how to hover. I am using the JR 3810. Please help
Thanks

For normal flight, pitch settings low stick= -2, 1/4stick= -1, middle stick= 0, 3/4stick= +5 or +6, full stick= +9 or +10. Remember every swashplate, control arms etc, all must be mechanical level before you set your pitches.

Mid stick should b between +5 - +6. If left at 0 u will hv very high headspeed at mid stick and little to play with for normal flight.

Yes, for beginner who wants to hovering at mid sticks. Correct hovering point should be at 3/4 stick. Think about it, when next time you switch to idle up, all hovering is at 3/4 stick and hovering at a (idle up mode) higher headspeeds will provide more stable flight. If you just hover around in normal mode (slower headspeed), when suddenly there's gust of strong wind, you will not be able to get control (counter attack) the direction of the wind coming. Again, correct hover should be at 3/4 stick cos you don't want to start all over again to get use to stick placement when comes to learning idle up (3D flight).

Another point, in normal mode. you need a negative like -1 or -2 at below mid stick to counter attack strong wind and bring back your heli before it goes higher. Got it?

Got it guys. Does this mean the the trottle curve will be leanier? I assume that at hover and at full pitch/trottle, the rpm should not increase. If so at hover, should the trottle setting be at 70% or less?.
Thanks

keeping headspeed constant is a challenge for everyone. this means the thr curve will not be linear. however, yes, headspeed should be close to the same from hovering to flying around... unless you have st modes set.

I usually don't fly in normal modes so my HS for normal mode and St1 and St2 are very different for suiting my flying preferences.

What engine are you using? If it's an OS32, then go with a straight 'curve'

ie: 0 deg pitch at idle throttle
5 deg pitch at 50% throttle
10 deg pitch at 100% throttle

You don't need -ve pitch for hovering, and it's a bad idea, as beginners
tend to slam the throttle down when the heli runs from them.

I've been flying shuttle all my (rc) life, and this is a proven setting to start with.

Do you have a proper flybar, or your flybar is just balls at the end?

It takes a LOT of gust to push a nitro heli around, even if it's just a 30 sizer.

Take a look at my video Here at the ending, just before landing, you can see from the smoke trail that the wind was very strong. But it had little effect to the heli.

Also, there really isn't such a thing as a correct hovering point. It's up to you to set it to your pref. I hover at normal, and idle 1 at 50% stick. And about 60% for idle2 (which is a -9 to +9) setting.

thats what most people try to achieve.. and its really very hard to... that's why we run governors to help us maintain the headspeed. having a consistent headspeed helps keep the tail stable as well i guess...

Thanks for all the imput guys. I am running an enya 32 with a tuned pipe. I dont think hovering will be a problem and if history repeats itself i will get itchy and try some simple manuvers. I have given myself -2deg at idle just in case I need to decrease height. The heli comes with a proper flybar and added weights for extra stability.
Cheers!

I started off with 0, 5.5, 10 pitch when i was still on training skids. Besically, you use this when you're afraid of slamming your bird down when you slam your stick down in an crash.

However, once you're off skids, and can hover properly, i wont advise you to use 0 pitch as your bottom stick. When you fly higher, you will find your bird hard to come down. Also, the bird loses stability when you reduce throttle too much as you want to bird to descend. If a big wind suddenly gusts, you can say bye bye to the bird. I've seen this 1st hand at the flying field.

Suggest you give yourself around -3 of negative pitch. You will descend much better...

Once you progress even more, you can start to add more negative pitch, and eventually, your hover point (5.5 degrees) will be around 3/4 stick. This is important as it will help with your transition to IDLE UP 1. Most people have their hover point at 3/4 stick in IDLE UP.

[Blackite207]

I would like to thank all you guys for all the help.

I had a successful 1st day hovering around and getting used to the chopper. It was my first without the training skids and I could "feel" the heli more. More responsive and some what easier to control.

Mt final setting -2 at idle, 5 at hover and 8 at max trottle. For a start, i am hovering at mid stick and I dont think transitioning to 3/4 for hover will be an issue when the time comes. Looking into scale helis instead of 3D for the time being but who knows when the itch will come.

Now I have to learn how to fly her around without crashing. Is there a programe or set manuvers that will train you in orientation.

Thanks again
Cheers!

Fly with me.

Thanx!

Having 0 deg pitch for normal mode flight is not the correct way in setting up no matter you're a beginner, advanced or expert flyer, F3C or 3D.
Of course when you're already a competent flyer, no one would follow the manuals, but none of the manuals (JR, TT, Hirobo) that I've come across ever advised 0 deg pitch setup at 0% throttle.

Reason being that there's no room for u to recover if your engine stalls in normal mode...if you have at least -3deg pitch and your heli is at about say 3 storey high & engine stalls, u can only see your headspeed decay slowly before your heli hits the ground like a rock.

With -3deg pitch, there is still a chance you can autorotate and land safely...


Of course, you can always have your personal preference in your own setup, but pls think of safety...there's always a reason why certain things are meant to be that way because someone else have probably experienced it & probably learnt it the hard way.
