| Subject: | Autopilot servos for XP |
Hi
I think I've worked out the trim issue - I'm going direct with a Ray
Allen unit and if I need more travel for pitch trim I will add a
pulley to double it or split the difference with a lever. Thanks for
the feedback.
I'm now looking at fitting a pair of Dynon AP servos and was hoping to
achieve enough movement from them - I measured the stick movement and
it looks like the elevator pushrod moves to and fro 3" and the roll
(measured from the bolt holding the rod-ends on the aileron pushrods)
seems to move 4" but the wings are not fitted at present so not sure
if there is a more limited range of travel.
Can anyone suggest if the roll can be achieved from the standard
attachment point as I have 3.6" of travel available with the outside
hole on the long arm on a SV32 - there is an extra long version
available but it's normally fitted with the next size up (SV42) which
then adds an extra 1lb weight and draws twice the current - which is a
scarce resource when running a glass panel etc.
If there are any indications as to the effort required to move the
controls that would be useful - the figures for the servos are quite
good but I have no idea what the potential forces on the stick might
be - I've only had a few hours a long time ago !
Cheers people

Esa,
I used Adel clamps for the wing pushrods. After flying to determine I liked
the setup, I added a pop rivet to more permanently secure the clamp to the
pushrod.

Hi,
Does anyone have extra clamps to connect autopilot servos to pushrods? Or
good instructions to make those are as well welcome.
