The design of the travel is to help a KR turn without a lot of rudder input.
With the +20 -10 set up, the aileron that is deflected more will actually

Hi Guys,
I'm tyring to sort out aileron travel. In the construction manual there is a

I'm the guy thats build his one piece wing,I'm using the AS5046

have? The plans call for 20 degrees T.E.U and 10 degrees T.
I don't see how MORE could possibly be a problem. If it is, that is a
problem I would welcome.

I don't see how MORE could possibly be a problem. If it is, that is a

I don't even think my ailerons run the full travel as called for in the
plans, and they do everything I need them to do so far. You can easily
limit the travel at the stick later, if you feel the need.
The new airfoil results in a pretty stiff aileron feel at high speed. The

I hate to contradict you Brian, but more travel does not necessarily
increase sensitivity, but WILL make for a better roll rate when fully

The 20 degrees up and 10 degrees down is the differential action that helps
the KR to make turns with no rudder input. I guess if it dives you have to
correct, but you've already got your hand on the stick. Mine dives a little
in left turns, climbs in right turns (or I may have that backwards)
Another thing I just re-called is models generally don't have deferential
ailerons. It's 20 degrees up and down not 20-10, but thanks for the
discussion.

Every model I've ever built with ailerons has had differential. In some
cases it's been no down travel at all,

Yes Dan it is 20 degrees up and 10 degrees down.
That is also expressed as a maximum limit of movement in the plans.
