REFLECTOR: Canard Center Hinge

Richard;

 

I used self-aligning ball bearings that bolt to the center pivot support.
The o.d. of these bearings fit snugly inside the ends of the torque tubes
(concentric version). I haven't been able to find a photo. With some
research I could probably find the bearing part # (from Aircraft Spruce).

Dennis,

 

I would appreciate pictures and yes I am talking about the bushing dead
center.

Are we talking about the bushing at dead center between the two elevators?
If so, I redesigned that. I inserted needle bearings inside each elevator
tube. Next I took a steel shaft (recycled from an electric motor) and
inserted it in aluminum fork in the middle. Now each elevator tube slides
into the steel shaft. No way for it to work loose. I can send photos if
anyone's interested.

I was on my third test flight today and I noticed the elevators  were no
longer trailing at the same angle so I landed immediately. Here are the
shots from 5,500 feet at 120kts IAS (130kts TAS). 



(Second picture of the canard will be in the next email.)


After landing I seem to have some play at the oilite bushing. Everything
else is tight from what I can tell. All that is left is the bushing. From
what I am guessing is that the left elevator has the pressure of the pitch
trim spring and the right elevator has the downward pressure of the sparrow
strainer. 

Any ideas would be helpful. My plan is to remove the canard and examine the
oilite bushing.
