Hi Graham
What is high, 10, 50, 100lbs. I have just got a new =9CPermit to
fly=9D and completed the air tests just before the Rally. This
year I did the VNE dive after trimming out at 125 knots, the stick
forces were definitely there but no where near as great as last years
test which was done with the aircraft trimmed out at 110 knots. My point
is that I don=99t think I was pushing anything like 50lbs, I was
very uneasy having completed the test and made a point of asking advice,
I was concerned not to overload the system. What is the force required
to bend a 1=9D dia piece of tube?
Sorry I missed you at the Rally
Best wishes
Richard

Richard,
stick loads are indeed quite low most times, but if aircraft is not in
trim pitch loads can be quite high.

Hi Tony
As you have stripped the paint off them both, for piece of mind crack
test them. You can buy the dye line system [3 aerosol cans] for a few
quid I mean dollars from an engineering supplier.
But that aside just lets look at the loads your going to put this part
under, to my mind if you were to exert the kind of load required to
cause a failure you would have ripped the whole unit out of the floor!
Stick forces re not high in the Europa, in fact there low and very well
balanced don't worry.
Good luck
Richard

Gidday, again,
With my cranked control sticks, I stripped them of paint and inspected
them to notice a distinct =9Ccrease=9D where the beginning
of the crank occurs. It is on the inner edge, and appears to be the
=9Cinner=9D point of a bend, at the end of a vice gripped
section, as the bend is made by pulling towards the operator, if in fact
it was done in a vice, which I very much doubt. So, the actual radius of
the bends looks fine, but on the inner portion of a ben, on the ends of
the central straight sections =9Cbetween the bends=9D, there
is what appears to be cracks. There is no doubt they are manufacturing
marks, and I would like to ask if anyone else has an unpainted stick, if
they could inspect theirs and see if they are the same. I am not going
to paint mine now, but possibly coat them in a clear polyester coating,
like you put on polished floorboards, so I can look through it and
inspect it from time to time, if in fact I don=99t get these
replaced. Any help appreciated, and here is a few photos to highlight my
concern.
Regards
Tony Renshaw
P.S. You can feel it, and the tube that is of the bend appears a
nominally thicker radius, probably
