Alexander Pearson, known as Alick, developed this kite in the early '70s
as a simplified version of the ROLOPLAN. In the original version, this
kite had square proportions and no nose keel, and a simplified two-legged
bridle. The Pearson Roller in its original form is likewise a relatively
small kite and because of this it must be constructed with due precision.
Naturally, it can be scaled up.
ORIGINAL PEARSON ROLLER Measurements (in cm)
Seen from the nose, the bridle points of the kite are on the
upper cross-spar (w1), and on the forward edge of the keel fin (w2).
Constructional Details:
Two 150° dihedral connectors (e.g. Eddy connectors) for 8mm
wooden spars (6mm carbon is also fine).
The sails and the keel fin (a separate piece!!) should be sewn together
tightly (possibly with line).
All the spars fit into pockets (big circles).
At the places where the cross-spar lies on top, stitch on bands to
secure it (important).
In the centre underneath both sails are bound tightly together. At
the outer end they are tied with an adjustable line.
Sew a spar (X) onto the keel fin.
Bridle, in total 183cm long.
In Alick Pearson's model, the keel fin could move freely, i.e. it was
not sewn to the lower sail. At points S1 and S2 eyelets were
fitted. The keel fin was then attached by line to the tip of the spine on
one side and to the lower cross-spar on the other. Anyone who doesn't like
this arrangement can sew the keel fin to the lower sail in the normal way.
