Hi all, what is a good rate to have my dual rate switch set at for learning to fly with ailerons properly?

Hi John, a bit of a difficult question, depends on how big your ailerons are etc.
I used about about 60% on low rate and 100% on high. I also added about 30% expo in both my settings (using a spektrum dx6i). You can always try a lower % throw on your low rates and see how it handles, it is a bit or trial and error so to speak.
Hope that helps

Hi there 900dukess, yes I suppose your right it probably does differ, size dependant, I think I will try about 60%. What is expo, what does it alter?
Thanks for the response, John

Spektrum dx6i, dx7 etc have expo not sure about other brand rx's. Expo is a bit hard to explain but it makes the controls less sensitive, so makes it less "twitchy" to inputs, but still allows full travel, hope that helps

I have just looked at the TX and it does allow an expo setting per channel, I have set the aileron channel to +30% though it could be -30% I presumed you meant +, is this correct?
Once again thanks for the feedback, John

Yer John +30%, sorry about the mistake in my earlier post, I meant TX not RX, silly me

Yer John +30%, sorry about the mistake in my earlier post, I meant TX not RX, silly me No probs, I hadnt noticed the TX/Rx mixup, thanks for the help. All going well I will get a chance to try the settings out on Wednesday. Once again many thanks, John |

thought I'd chime in with like a true nerd with the definition of exponential. Rather than the controls being linear (10% stick giving 10% aileron, 20% giving 20%, 90% giving 90%), they work exponentially. So, 10% stick might only give you 2 or 5% ailerons, but as you give it more and more stick, it gives you more and more ailerons so that where the first 20% might only give you 10% movement, the last 20% might give you a further 40% movement. It's kind of hard to describe in words, but look at this graph:  imagine time (x-axis) is the amount of stick you give it, and population growth (y-axis) the the amount of aileron movement and you should get a pretty good idea. If it were set normally (linear), the graph would make a straight line at 45 degrees. |

It makes the center movement of the stick less response at the expense of the end travel of the stick is more responsive. The can be useful for planes that are pretty twitchy and for take-off and landing where you want fine control but still want full throws up in the air.
How it is set is mostly personal and associated with the particular plane. Best course is to set it low and work up. Make SURE you are setting it the right direction. On some TX setting it + softens the movement, on other TX it makes it MORE aggressive and you need - .

Thanks chaps, I think I'm beginning to understand. I guess experimentation is the way forward.
Very helpful, John

Thanks chaps, I think I'm beginning to understand. I guess experimentation is the way forward. Very helpful, John That's the way John, set in on one of your rates, wiggle the stick a little, you'll see that the control surface only moves a little. Wiggle it to max, control surface will travel to max. End travel is not effected, only the movement up to the % you dial in. |
