Assembled parts.  Cavities are filled with block balsa and then sanded to the contours established by the core parts.



After final assembly the model weighed only 13.7 ounces less the battery, but was also tail heavy.  1 3/4 ounces of weight was added below
the engine on a tray, also restained with a screw.  It is still 1 ounce shy of the 16.9 ounces needed to reach 8 ounces per square foot.  
The prop is an APC 8-6 electric which works well and is not stressed overly due to the low rpm.  This particular .049 will run 5 1/2 minutes with this prop.



Servos are mounted as far forward as possible and the AAA Eneloop battery fits right  behind the firewall.  A Lemon 6 channel receiver is used.  60 pound
test Kevlar thread is used for the pull pull control system.  The Kevlar thread is tied off with five or six half hitch knots and then a drop of thin
CA is applied, quickly touched by the edge of a paper towel to wick off the extra CA so it remains only on the knot and does not  travel down the thread.  
It is easy to keep the large initial loop by passing a dowel through the first loop of the knot and then withdrawing it before glue is applied.
