COntinuation of elev, rudder, stab

Photo 1 Stab extension prototype on right fin

Photo 2 extension modification of rudder so extension passes through central web with inboard travel.

Photo 3 Closer view of extension prototype and rudder.

Photo 4 - 8 With the opening in the central web for the extension the attach area for the control horn is now too weak and the first of many re-dos are in order. The existing balsa re-enforcement had to be removed so a hardwood replacement can be glued in. A high quality wood chisel cleaned up this area very well. This hardwood member will now have blind nuts installed in the recessed area to bolt the control horn to, and a balsa filler will be glued on top to make the area flush. The hardwood should now provide an adequate structure to move the rudder from the action on the control horn. The bolts will have to be the correct length so as not to penetrate past the blind nuts.
