Optic 6..

[heliward0]

HELP.. i have a hitec optic6 transmiter and would like t adjust the (d/r)duel rate and the(exp) exponential contol BUT cant seem to get into the menus to do said task i was woundering if any one could help me??i could do with simple advise MAYBE its ME doin something wrong!!!

Well the manual says this about dual rates...

You can use the dual rate function or the exponential
function to reduce the aileron and elevator travel in flight by
flipping switches. Dual rates are typically used to reduce a
model's sensitivity and cut down total travel. Exponential
functions make the response slower around center and
larger away from center.
You can use both but they are activated by the same switch.
You may wish to use Dual rate on one side of the switch
and exponential on the other.

48. Aileron Dual Rate setting. Get to the D/R menu by
pressing one of the Up Down Edit buttons repeatedly until
D/R appears, as shown.

49. The aileron dual rate setting automatically affects both
ailerons if the flaperon function is active. To set the aileron
dual rate, move the arrow by pressing the Right Cursor
key until the little arrow is under or over the numeral 1 (the
arrow depends on the position of the Ail D/R switch above
the right stick. Now move the aileron D/R switch up or
down, noticing the position of the arrow. You can set two
dual rates, one for each switch position. If you set them,
be sure to note which switch position turns them on.

50. By pressing the Data +Increase or -Decrease keys, you
can add or subtract from the numerical value displayed.
Note that you may pick a value anywhere from 0% to 125%
(125% is larger than the normal amount, so if you do this
be careful not to exceed servo travel limits and cause
stalling or excess current drain). If you quickly want to get
back to the default 100%, press the Clear key. We suggest
using an initial value of 75%.

And this about exponential:

1. Enter the programming mode by pressing the two Edit Up
Down keys (the two keys on the far left) at the same time.
Press either Edit Up Down key until the EXP menu appears,
as shown.
2. To set exponential for channel 1, move the arrow by pressing
the Cursor Right or Left keys repeatedly until the arrow is
over the channel number you want. Now switch the
appropriate switch up or down, noticing the position of the
arrow. You can set two values of exponential, one for each
switch position. By pressing the Data +Increase or
-Decrease keys, you can add or subtract from the numerical
value displayed. Note that you may pick a value anywhere
from -100% to +100%. If you quickly want to get back to the
default 0%, press the Active/Inhibit (Clear) key. You should
understand that you won't see changes in your model's servo
response unless you move the sticks. To get a feel for how
exponential works, just hold partial stick and switch the Expo
on and off (one side of the switch should be set to zero expo).
You'll see how it affects the servo travel.

3. The values you set for exponential are highly dependent on
both the model and pilot's preference. I normally recommend
a start value of about -10% to -20%, and many test flights,
slowly increasing the number until things are "right".
Obviously this depends on the pilot and model so go ahead
and fly it with Expo only on one side of the switch, turn it on
and off during flight, and change things to suit yourself. Or
don't use it at all if you don't like it - it's not for everyone.

4. Repeat this procedure for the expo settings on the other
remaining channels.

5. Return to the regular operating mode by pressing the two
Edit Up Down keys simultaneously.

thank you for the reply.. but i have done as this says a number of times but cant get the d/r menu up,, i just want to make my servos more responsive on my t-rex( see dosile t-rex post)

[jimbob]

Well maybe you just need to increase the end points... but....

To access the D/R menu, I beleive its the same as expo above:

Enter the programming mode by pressing the two Edit Up Down keys (the two keys on the far left) at the same time.
Press either Edit Up Down key until the D/R menu appears as shown.

Hope this helps...

[heliward0]

yea i have just held both down and scrolled the menu but still no d/r is it ME???

[jimbob]

Do you get any of the menu options when you hold the edit keys down?

You have to press and hold them...

Do both keys work otherwise? Perhaps one of the is bust?

[heliward0]

i get ,,model sel,,reset..time,,mode,,ppm,,sft.n,,copy,,120',,he li,,and model name(t-rex-1),,

[jimbob]

I think your holding them down and then turning it on right?
You should turn it on, then press and hold them both afterwards. You are getting into the system menu instead of the main menu I believe.

[Nutz]

It should be around EXP,REV,ATV in the menu system.

Correct.

[heliward0]

I Am A Dumb Ass!!!!!!!!!!! Thanks Guys,,, WOULD 50%BE OK DO YOU KNOW??ITS SET AT 100%!!

[jimbob]

50% what?

If you mean dual rate, then 50% will give you half the movement you had at low rate.

[gazza]

No less than 60% is ever recommended on dual rates, I never saw the point of it with helis anyway. Suppose it depends on how much of a panicker you are

Surprised you never got a thanks for all that cracking info Jim
