Tim,
I experimented with many different materials for the outrigger legs and it
was not until using 'nylon 66' that the strength, flexibility and longevity
were all OK.

Ivan

Remi,
Maybe a bad batch of legs supplied to the Company. Tell the Company and
return them for testing. They should send another pair out hopefully from a
different batch.
Cheers,

emergency repair designed on site just to allow me to go back home: the
repair was made using the existing remains of the nylon rod lengthened with
scrap aluminum tubing. When I finally received the nylon rods ordered from
the Europa factory I could not use them because they were slightly too short
and badly machined. So I ordered a length of 1"1/4 Nylon from ACS and
installed them immediately. At the first landing, one of the all new legs
broke just at mid length. I was very embarassed as this happened on a big
airport were I had the honor of a jumbo eight wheeler fire truck! This time
I managed to repair quickly as I was carrying the old emergency repaired rod
in the aircraft. I am now afraid of flying with the aircraft as it is, as an
out rigger leg can break again at the next landing.

the upper end which seems logical to me.
