Arrow II Update
The Arrow II updated instructions are shown here. We have eliminated the old style airbrakes and now use the ones shown. Just glue the new brakes to the carbon rods as shown. We have also increased the cabane area by extending them above and below the wing with 4 pieces that are attached to the top and bottom of the wing as shown. There are other mods (secret) but these are the ones you will need to know during construction. Also, the small 3mm carbon strip in the middle of the top wing has been eliminated.
