Question
Replacing a broken hinge

Hi all. I fly from a mesh runway and today on my 100cc Extra I snagged a tear with the tailwheel. It was like an aircraft carrier landing!

The tailwheel caught and got pulled up into the rudder and broke the bottom two hinges. I got lucky but now the two hinges need replaced.

Any advise? Looking for an alternative to removing the rudder and replacing all of them. Ive done that in the past and dont particularly enjoy it.

Thanks!

Slotted hinges can sometimes be bent and slipped into place with the surface at a large angle. Round type hinges aren't so forgiving. But... if you broke 2, you likely stressed others so replacing all wouldn't be too terrible of an idea.

I have to agree with this
Roff I know it's a pita but changing them all is worth not loosing an entire plane....good luck

Are the hinges the flat or the robart round kind?


Either a sharp knife, a razor saw or a large dremel cutting wheel at a slow speed works.

Yea. I think it’s time to replace all. Maybe I’ll make the rudder removable.

I did a little research and looks like a soldering iron works well.

Thanks for the tips.

Another tip: don't put too much thought into cutting out/drilling the old hinges. Placing new hinges next to old ones will work nearly every time.

Second all the comments above.

Go back in with the Dubro heavy duty hinges except use one long piece of music wire that runs through all of them. That way your rudder is really easy to remove. I've seen people do that with ailerons and elevators too, although that's kind of pointless most of the time.

If the old hinges are round you can use a soldering iron to melt them out.

Robart use to offer the large pin hinges w/o pins for use with user supplied music wire hinge pins for removable surfaces, etc. I have also removed the pins from these hinges for the same use. Not difficult, snip off the small rivet end and pull the pins out. You can do the same with installed hinges with a small Dremel carbide burr then work the pin out. This is good if you want to salvage several hinges on a surface when only one or two are broken or worn.

Volgelsang offers those as well. http://www.vogelsang-aeroscale.com/ The 5mm ones would be awesome but expensive!
