Background info- Very much a heli beginner with a trex 500esp stock and just over 100 flights. I can tail-in hover good and I am just working my T's at 90's and figure 8's. This is coming well and I WILL have it in a day or two of good practice sessions.

Question- What is a good cyclic configuration for learning at this point? I was running 6+ degrees with 30% expo and I find I chase the heli some. I know this is what I am learning to control, but I just thought if I could calm down my cyclic a little that I may learn a little faster.

I just came in from a flight where I set the cyclic to 5 degrees and the expo to 25% and it did seem to help. My theory here is that possibly having more authority around center stick where I spend most of my time, and then reducing full throw, it may help.

Any thoughts?

Thanks all,

Hi whbell

i think you have the right idea , i would stay with 5 or 6 degrees of cyclic , and try reducing your expo , say 5 degrees at a time , and see what feels right to you

also some people ( myself included ) don't run any expo , there is no right way , it is just personal preference , cheers

Thanks copperclad,

This was a thought I had also. I just tried 20% expo for a 10 minute session and so no big change from the 25%, I will continue at 5% expo changes (slowly) until I find the spot.

jesus1895,

DR is Dual Rate? I have used it in the past on my fixed wings, but have not seen it viable for helis. I am glad to take your suggestion, but I don't know how to apply it. I guess DR for cyclic but that leaves me with a lot of other questions. Can you give me more detail? This really sounds interesting.

Thanks,
--Bill

IMHO,

Screwing around with dual rates and expo is not a good thing with a heli. As you progress you will have your hands full without monkeying around with switches. 20% max expo on cyclic and forget dual rates. Patience and practice, grasshopper.

Ask your doctor if your heart is healthy enough for Radio Control Helicoptering.

There is no harm at all with adjusting expo. Really no need for the OP to adjust DR at this point. The amount of expo you'll use for any particular heli is up to you. I have a heli that I have to run at 30%, another that has virtually none.

Well I found the combination, 5 degrees cyclic with 20% expo. This is exactly what I needed at this point. I did like 6 degrees cyclic and 20% expo, and I may soon move back there, but for now this was enough change to the handling that I was able to go into my first real FF this morning. Man this bird can fly!

I don't think I need to experiment with DR at this stage so that is off my list.

Thanks all for the input.

What FlaG8r said is the truth about expo - it is heli dependent as well as a preference. Some helis have extremely quick cyclic, while others are sloooow! Use expo on the quick ones as needed.

I found one of the impediments newbies have in learning to fly is using a setup that is too mushy/soft. If I understand this post correctly, the OP is using +5-6° pitch at maximum high stick. Is that correct OP? If so, you are doing yourself a disservice. A heli without sufficient control authority (i.e., enough collective and cyclic pitch) is simply hard to control, not easier. You should use reduced negative collective pitch to around 0° to -2° to prevent slamming the heli in the ground at this point, but keep the maximum positive pitch at about 10° and mid-stick at 5°. Use a good amount of expo (30-45%) to reduce overcorrecting.

As your skills improve, you will want to reduce expo, adjust center stick to be 0° collective and make low stick -10%, maybe -5° to -7° initially in normal flight mode while getting use to having high negative pitch. Idle-up modes should be equal but opposite pitch at full positive and negative stick. This will get you prepared to do 3D or aerobatic flying.

Happy flying!

Hi rexxigpilot

i could be mistaken but if you look at the posts title "Cyclic question for learning hover"

you will see he is asking about cyclic pitch , not collective pitch

hope this is some help , kindest regards

rexxigpilot,

The original question and pitch numbers were targeted to my cyclic configuration, and I feel now I have enough understanding on this topic to be able to make adjustments as my skills increase.

Now for my next topic. Collective question for learning FF. As a mater of fact I started wondering about this topic just tonight while flying my last two packs of the day. I don't want to hijack my own thread here, but the heli is set up for collective mechanically for +12, 0, -12 and all of that is available in idle-up 2 (I don't go there yet). I have my pitch curves tuned down more than that in Normal and idle-up 1, and I understand the importance of the switch-over between the modes. Please be assured, your input has been received and is being processed.

Thanks for all the help everyone,

--Bill

Hi Bill
i have mine setup the same way , i set my machine up so i have full collective range mechanically , say it is -12 through +12 , and then i use the pitch curve to limit it to my flying style ( sport ) to -4 through +12 , then i try hovering and if the cyclic ( right ) stick is too responsive , i go into the swash screen

aileron 60
elevator 60
pitch 60

and i reduce the aileron and elevator range to soften my cyclic response

of coarse this is all personal preference , one person might like tons of cyclic throw , and someone else might like it different

i have always felt it is best to have it the way you are comfortable with it , and as you see you want it different , jump in and change it , none of this is chiseled in stone

kindest regards
