The next set of plans is of the DAVIS ACRO PRO and was drawn by Steve Schwartz of 1228 Fremont Street, Dover, Ohio 44622.
Wing span of this fully aerobatic model is 88 with a
total area of 1200 squares, a weight of 13 to 15 lbs. Power suggested is
a Super Tigre 3000, which should give endless vertical performance.
These plans come in two large sheets, and airplane looks
like a modified Laser. (Editors' Note: This model is of a home-built
aerobatic aircraft) The full size aircraft was displayed and flown
during the Seventh Annual Rally of Giants at Converse, Indiana.
SHEET NUMBER ONE:
This shows the left fuselage view with half top view and fin, with
rudder, also the fuselage formers. The fuselage is built of 1/8 inch
balsa sheet sides with 1/8 inch ply doublers from nose to tail. The
rear deck is built up and sheeted with balsa. Cowling is also built
up of balsa and ply. The landing gear is of one piece aluminum
with Laser style wheel pants. The entire empennage is of 1/4 inch
sheet balsa and is amply braced to the fuselage with cable and
rods. A C-B tailwheel assembly is used. Fuselage formers are of
1/8 inch balsa sheet.
SHEET NUMBER TWO:
This sheet contains the left and right wing panels with rib
templates which are cut from 3/32 inch sheet balsa with light ply
root and station four ribs. This is to support the aluminum wing
tubes that attach the panels to the fuselage. Spars are 3/8 x 1/4
balsa top and bottom with shear webs between each of the ribs
from butt to tip. Both front and rear spars are constructed like this.
The butt bay, leading and trailing edge are sheeted with 3/32 balsa
from the spars forward and rearward giving a light but strong wing
panel. All ribs are cap stripped between sheeting. Ailerons are
cut loose after the wing is sheeted, then finished. Servos are
mounted in each panel near the ailerons. This should be a fast
building project as the construction is quite simple and straight
forward. With a weight of 13 pounds and a Super Tigre 3000 in
the nose, you should have an airplane that will do anything the
pilot is capable of . I do not believe the airplane will balk at
anything.
