Like World War II fighters? Most of us do, and this
time we have an unusual one, the plans for which are produced by Roamin
Research, P. O. Box 104, Yale, Michigan 48097. It's the Mig three,
used by Russia during World War II. It's quarter scale with a 101
inch wingspan, with 1700 inches of wing area, and powered by
a Quadra 50. It's a good looking airplane, and from what I have
read, gave a good account of itself during the big bash.
The plan comes on four sheets. The first sheet has the left fuselage side view and the top view with fin and rudder shown. Construction is sort of unique, although not unusual. First you build a horizontal crutch, then the one piece fuselage formers are slipped on after making sure they are straight and level. The firewall is half inch ply with a short ply box to mount the engine on. The entire fuselage is sheeted with one eighth balsa. The cowl exhaust stacks and air scoops, the canopy, are available from T & D Fibreglas of Garden City, Mich. The landing gear is shown on the plans as quarter inch wire, but it would be easy to mount retracts, and would be a shame not to. The fin and rudder are built from an eighth balsa core to which ribs are glued, then sheeted with three thirty second balsa.
Sheet two shows the right wing panel and the fuselage
crutch construction, plus the wire landing gear pattern. The center
section ribs are all one eighth plywood with balsa ribs in the outer
panels. There are two main spars quarter by half hardwood, on
both top and bottom, with quarter square balsa leading edge spar
and block balsa wing tips. The whole wing is sheeted with one
eighth sheet balsa. The ailerons are constructed the same as the
fin and rudder, with one eighth sheet core with lightening holes,
with ribs glued in place when sheeted. The wing has two section
split flaps which are shown on the plan. The wing is constructed
in one piece, but could easily be made into a two, or even three
piece wing.
The third sheet shows the left wing panel in full detail, the same as the right panel. The stabilizer and elevator are also shown on this sheet. The stab is built up of ribs and covered with three thirty seconds sheet. The elevators are from a balsa core with lightening holes and ribs and are fabric covered. Tips of the stab and elevator are from balsa blocks.
Sheet number four contains all fuselage former templates
and all wing rigs. Since this wing is tapered both front and rear, there
are quite a few different ribs to make. Flap construction is also
shown, along with fin and rudder spars.
