Hi Marcos,
I=92d reconsider the spring gear. It=92s heavy, stays in the wind
across the
belly and leaves too much bounce in landings for a light 601.
The original gear built into the wings is more difficult, but tracks
better,
needs little to no maintenance and their stress is better distributed on
the
plane.
The original gear is lighter than what you=92re going to find in
composite as
well.
The only advantage for the spring type gear is the work putting it on.
Yes,
it=92s easier, but a lesser product in the end in my opinion.
Respectfully,
Larry McFarland 601HDS with standard gear
Piper PA28 with like gear.

Hello all,
I=B4m starting building the center wing, main spar webs are ready and
also
ribs. At this point I have to plan some modifications to install the
landing
gear. I want to change the original for the aluminium spring gear and I
want
to build it from 7075T6. Groove spring gear is spensive and the main
problem
is deliver this big part to Spain. If someone has the main dimensions or
the
plans to scratch build this part would be apreciated.
Another possibility I=B4m study is to use composite legs fabricated here
in
Europe, has anyone using them with good results? The main advantage is
the
weigh saving.
Thaks to all

Marcos,
I=92d also recommend you also reconsider 7075T6 as it has a tendency to
corrode badly. It=92s stronger, but not a long life aluminum.
It would tend to fracture much easier in high stress even though
initially,
it=92s much stronger than the rest.
