Peg installation and wing balancing
Do not forget to properly set the tilt angle of the peg, it balances the load transmitted to the ship during launch by the
index and middle fingers. This tilt is different for every pilot, due to individual differences in length of the fingers. Make
sure to base yourself on the joint position of the last phalanges! A good general indication is somewhere between 5 and
7 degrees. As each half wing has got 7° dihedral angle from the root, your peg can finally look pretty vertical from a final
front view.
Also the peg’s “yaw” alignment matters. Parallel to the fuselage is generally standard, but opening it up a little bit with
the trailing edge to the outside means it will slip away from the finger tips at the end of the launch easier. Recommended
range is from 2 to 5 degrees from parallel with the fuselage towards the outside. This angle is obviously set when cutting
the peg’s slot through the wingtip.
Drill an undercut of the peg’s cross-section through the wingtip, with a 2mm bit for edges of the peg section and 3 holes
of 3 mm at the center, and finalize the slot size with a small nail file to get a tight fit. Check your desired mounting angles
as you do so! Put some tape above and below to prevent from unwanted traces of glue; slide in the peg, and wick
medium or thin CA into the joint. Then make a smooth joint on top and bottom, as light as possible.
