This kit is made from the Great Planes plan, not the RCM plan. \u00a0The fuselage is put together with tabs and slots. \u00a0The\u00a0plan shows a tab and slot at the top of the windshield, but I eliminated that one just for the sake of simplicity. \u00a0Also, the top half of the firewall is triple thick on the plan, but it\u2019s only double in my kit because I didn\u2019t see the point of the extra chunk of wood.<\/p>\n
The wing plan shows the bottom leading edge sheeting extending from the leading edge halfway to the main spar. \u00a0Constructing the wing this way will allow the wing to twist, so my kit has the bottom wing sheeting all the way back to the main spar to create a full D tube. \u00a0The plan shows lots of plywood dihedral braces. \u00a0I\u2019m including a lot of braces of various widths, so you\u2019ll have to figure out where they all go.<\/p>\n
One other thing shown on the plan\u00a0is grooves in the spars, so you can put your shear webs in the grooves. \u00a0If I were building one of these, I would just use a regular stick with no groove, and stick the shear webs on the back side of the spars the easy way.<\/p>\n
It sounds a bit complicated, but it will be pretty obvious once you dive into the project. Use 1\/2\u2033 balsa sticks for the leading and trailing edges, and use 1.25\u2033 tapered trailing edge stock for the ailerons.<\/p>\n
