1996 Cal told me that I had too many rivits on this end but was OK. |
 |
The elevator control attachment. Height of hole in vertical piece determines amount of movement. Reference plans for dimensions. |
 |
Horizontal stabilizer connection to fuselage on right side. I installed the doubler reinforcement on the inside rather than the outside. Threaded a 4130 rod and installed it through Bulkhead 'E' for attachment. |
 |
Horizontal stabilizer connection to fuselage on left side. Note my method of putting a drop of 'Bright Red' fingernail polish on the threads and nuts of all bolts. If you do this as you install them, you don't have to go back and check them because you know you already tightened them. You can also tell if they have loosened because the polish will crack. I use this method on the completed aircraft assembly. |

I need opinions about this change.Thanks |

My .020" channel spar,have 2 5/16"x 68".It is 5/16" more wide,and is fixed a little more back in the H.S.Near of 3" of edge |
 |
This is my particular measure for the H.S. spar |
 |
Measure of my H.S. skin |
 |
I make a line at one side of 3/4" (previus picture) and another in the opposite side at 2 7/8" of the same trailing edge.Total wide of the skin is 26"(development) |

Elevator ribs,maked in same form that H.S. |
 |
Ribs ready |
 |
To level out the H.S. I use two telescopic support |
 |
I fix first my hinges at tube with adhesive tape, and after fix to H.S..In this form they are straight.The central hinge is necessary maked more longer that 6" (7"-8") |

Measurament respect to spar |
 |
1/8 x 12" bit it is crosing the angles and fuselage |
 |
I have balanced the elavators 100% using 1/4" alloy plate bolted on to 4130 steel elavator end caps, and 550 grammes of lead plate.That's about 1.2 lbs each end, total 2.4 lbs as opposed to 1 lb as per unbalanced plans. |
 |
The lead plates were cut with a knife and are bolted between a steel plate and alloy bar.I will put a fibre glass tip on both elavator and stabiliser. |
 |
The steel end caps with the weights on fit into the ends very well. |

The central screw replace the rivet. They fix the bulkhead "E", with nut plate inside.The frontal bolt take the reinforcement plate of .040", and another little plate of 1/8" |
