Here we go again,

Flying in windy conditions on an elevated runway with a roller, I tapped the rudder on the runway on approach. There is barely a dent in the bottom tip of the rudder. BUT, the rudder came completely off the plane and was held by only the pull-pull cables and the TW springs when all 4 hinges failed. (They failed in the same manner as all of the others failed, by ripping in half).

I went around with the rudder flapping behind the plane and banked and yanked it home with no damage and a surprisingly smooth landing.

What type of hinges failed as a result of such an inocuous rudder tap? mmmm.... uh...CA HINGES! I assume they were installed correctly as I have over 12 gallons of glow fuel through this plane.

From now-on I will donate all CA hinges to a home for the mentally disabled or a tent for stubborn circle flyers. I am done with CA hinges for good.....again.

For those of you who wish to defend the use of inferior hinges because it hasn't happened to you yet...go ahead and use them. It's your plane, just keep your homeowner's insurance paid so you can fix the damage you cause to the rest of us.

I'm sick of replacing failed CA hinges, although I am getting better at it these days.

OK, I'm done venting. I still think CA hinges are adequate for small scale and sport planes, but if you intend to fly 3D or fly any plane for more than 10 gallons of glow fuel, get real hinges.
