Gidday, again,
With my cranked control sticks, I stripped them of paint and inspected them to notice a distinct “crease” where the beginning of the crank occurs. It is on the inner edge, and appears to be the “inner” 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 “between the bends”, 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’t 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 bulged from the bending process.

Hi Tony,
My sticks are unpainted, uncreased & uncracked.
I would be looking to change that based on your final photo.
Brgds,
Roger

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

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

Thanks Richard,
It's just disconcerting to have what appears to be a crack on "each" of the bends. If they aren't on other sets, maybe they shouldn't be on mine either.

Hi Graham
What is high, 10, 50, 100lbs. I have just got a new “Permit to fly” 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’t 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” dia piece of tube?
Sorry I missed you at the Rally
Best wishes
Richard
