I would not recommend this one to a newcomer to scale jets, because it is not a particularly simple build. There are some vague areas on the plan due to some quite complex shapes in the original, especially where the engine nacelle meets the upper fuselage. Be prepared to be a bit creative with small bits of balsa sheet and block to get the required shapes and blends.
Although the plan shows built up fins, they could be made much simpler from soft 1/16" sheet, with little weight penalty.
The wing is assembled as one piece, with dihedral as shown, then inserted through the fuselage. Removing the shaded section from former 5 will be much easier if you partially cut through prior to building the fuselage. Sheeting is added above the wing after it is in place, and combined with the sheeting in the first wing bay, this makes an extremely strong wing root assembly.
Note the balance point shown on the plan is with an empty Rapier L2 in place.
The hinge I used for the opening hatch was simply a short length of aluminium tube with a U shaped bit of wire through it. The tube was fixed to one side, wrapping with glue-soaked tissue, and the two prongs from the wire glued and pushed into the other side.
The 3 mm diameter neodymium magnets (available from Derek knight, or SAMS Models) were let into recesses in the nacelle side keels and fixed using Cyano adhesive. They easily provide enough force to hold the hatch shut. The L-shaped motor retaining wire is just stuck in place with an additional piece of self adhesive aluminium foil (the same stuff the trough is lined with). It has never come adrift, as this part of the trough is slightly in front of the main exhaust blast.
The overlapping foil seal in the exhaust has proved reliable in practice, but make sure the foil edge sits neatly inside the top hatch BEFORE you light the motor each flight. It can easily get bent while you are cleaning the trough.
Two things I really like about this model are the fact that the motor is completely hidden, so the exhaust smoke comes out of the scale exhaust, and that it is really easy to launch, due to the shoulder wing. My example needs a 130 mN Rapier L2 to power it, but if you build yours lighter, you may get away with a lower powered unit.
If you decide to build one, please contact me if you have any questions about construction or trimming, and I will do my best to help. Have fun!

Test prints using A4 paper have come out exactly full size, but I have put a 4 inch scale on both pages of the plan so you can check.
