Aileron actuation

Its been a busy couple of weeks since my last post but a lot has happened...not all of it RV related.  ;-)

However, what is RV related is posted below and includes completion of the aileron actuation linkages as well as the start of the wing tip work.  For the wing tips I opted to use the hinge method of attachment that I used on the RV-9A.  It looks great and seems to hold up very well.

With the RV-10 the aileron linkages are a little more complicated due to the added row of seats.  In the picture here you see the torque tubes and associated bell-cranks that get employed to transition the forward location of the control sticks to aft of the wing spars.

Here is the bell-crank that converts the left to right motion of the stick to an up/down motion that moves the ailerons.

Using the hinge method of attaching the wing tips requires almost double the amount of rivets compared to screws.  In this picture you can see that I am using a rivet fan to space the holes out evenly.

Another view of the rivet fan in use.

After trimming the wing tip to size I was able to get it taped, drilled and cleco'd in place for this picture.  Still lots of work left before this is complete.
