Pitchhülse 68211

Hi!

After only some few flights with my new CP Piccolo [img]images/icons/cool.gif[/img] this item broke, and I diddnt make a big crash, only a gently landing in some grass where the rotor blades catch the grass.

Does anybody else have bad experience with this item? And does anybody know if there exists an upgrade for this weak item?

Regards

Paul

mine broke while the first flight -> one blade destroyed...

I don't have access to my manual.... do you mean the pitch slider?

If so, the answer is yes and yes.... I think. It is fairly fragile. I have yet to figure out why it was designed the way it was, but the living hinge is extremely weak. However, you should not break it in normal use.

Beware... there IS one way to break it in "normal" use. If you have accidentally mounted the anti-rotation link on the wrong side of the pitch slider, it can hit the upper portion at negative collective settings and stress the hinge.

It is possible that it was made weak in order to protect the rest of the mechanism and servos in the event of a crash. There is far too much energy for the delicate parts to absorb in a crash, and the concept or weak sacrificial parts is a very good one.

Unfortunately it is not an easy part to repair securely. My solution was to make a small semicircular piece of hard rubber (a cut down faucet washer) and CA it where the living hinge goes. But I always worried about the CA letting go. The real solution is just to have a couple spares on hand.

Someone I think did make an aluminum one without the hinge, but I don't recall who it was. Maybe they will come forward.

holly smokes, that's the parts i've been looking for all this time. where can i buy it.

Hi!

Yes yes yes! Thats the upgrade I need, where can we get that upgrade from?

Paul

it appears that he made it for himself and doesn't offer them for sale. Tim (TAW) also made an awesome one, but i think he also just made one for himself (not for sale).

now i'm starting to wonder if i should start making one for myself too.

Hi!

Just some translated text from the link. I have just send Wolfram an email regarding the upgrade. Let you know if we can buy one.

Meal, since a small weak point is with the Pitcholo the pitch case, put itself Tilo ruffle times and times evenly such from aluminum gedrechselt.. Now it has also still me (or mine Pitcholo) as a guinea pig auserkoren, so that I had made myself this evening to to insert this new case. Long speech, short sense: the aluminum version fits outstanding, the track run only with caliper gauge at the screws was adjusted and is correct up to 1-1,5mm at the page ends. Only point of negative: With the development I have the plastic version broken made..., thus @Tilo, the aluminum version come myself no longer raus... Here now a few pictures, flight testing comes on Saturday.

Hi Johnk!

That would be a very good idea, and after the first prototype, the next 100 upgrades will be done much faster ;-))).

And thanks to Hans-Otto for the link!

Hi!

This was the answer!

Hi Paul,
the alu-pitch-hülse was made from a "alu-freak-piccolotuner", who is going
to make a complete Alu-Piccolo.
I think, in some month he´s going to make some more of the pitch-hülse. My
exemplar was only a test.
