Phil,

Fly away!

Here are a couple of additional shots of how I rigged the tail control surfaces. Done pretty much like on a full size Tipo except I used one exit only on each side for both the forked elevator pushrod and the rudder P-P system. You can do the control horns like this if you like (4-40 x 1/2" bolts in hardwood dowels) - it keeps the control surfaces clean when viewed from above. I'd recommend using two plastic shaft and CF pushrods (e.g., Sullivan) for the elevators instead of the traditional FG arrow shaft and steel pushrod. This pushrod alone cost me a great deal of weight on the Pico - I think over an ounce which is significant on a 40" span model. I still have to change it. I'd recommend P-P for the rudder as shown. You would need two exits in this case but no hooded exits - everything would sit flush with the fuse side.

I used GP small hinge points for all control surfaces with epoxy since you are going into foam. Robart's are a little better quality I think but either will do.

Happy building.

David.
