rable amount ot its flying qualities.
The cut-aways drawn on the servo-mounting plate 59 conespond also
to these Microlc servos. lt goes without saying that you will have to
modify these cuts if you use different servos or another brand of radio-
control eouiDment.
Should bigger servos be used that could not be mounted between
formers 10 and 11, then these bulkier servos.can tind room between
formers 11 and 14.
Installation of the radio-control begins lirst by the making of the control
rods 60 and 61 which are made from 5 x 5 mm balsa stock. In accordance
with the plan you will also bind and glue to these rods kwik-links 62
and 63 which you will have cut to length and bent accordingly. To do
this, it you have not yet permanently assembled the control surfaces,
temporarily hinge the elevator to the stabilizer and the rudder to the tin.
Connect the kwik-links lo the control-homs and make sure both control
surfaces are allowed to move freely. lf necessary, bend the kwik{inks
until the co ntrol su.faces, when actuated by the servos, become entirely
free to move about theirhinge line and get their fulltravel (25olo the leftand
to the right lor the rudder, and about 1f down and 10p up torthe elevator).
The travel ot a given controlsurface can be modified easily. When you
use rotary-type servos, you ca6 increase or decrease the throw of the
control surface by hinging the kwikjink to the hole that is nearer to or
turther from the servo-arm screw, and you can also change the amount
of the control surface travel by hinging the kwik-link near to, or tartrom,
the hinge line at the control-horn point. When howev_er, you use linear-
type servos, then you aan only vary the throw of the control surface
at the control-horrt
Do not forget to give your power-back and receiver as much protection
as possible by wrapping them in rubber foam.

Trimming your'Filius' wilh colours is lelt at your entire discretion, and
there is no limit imposed upon one's lantasy in this field; however you
should always remember not to add too many coats of paint, decals,
colour-stripes, etc. so as not to increase the weight of your'Filius' to
the point where it would be detrimental to its performance.
The'Filius' has been developed with the minimum possible sink-rate,
so that the lighter it is, the better it will tly. The simplest, and also the
most etficient method will therefore be to apply a few coats ot paint,
sanding lightly between each coat with very fine grade sandpaper. A
few colours-stripes at the appropriate locations will enhance the appe-
arance of your model.
'f you want to paint your model, you will have to cover it enti.ely with
lightweight tissue (even between the wing ribs on the wing-underside).
Lay on two or three coats of heavily thinnder dope, allow each coat
to dry at least twenty-Iour hours so that solvents in the dope have
enough time to evaporale, then sand the model entirely untilyou obtain
a pertectly smooth surface. Then you may put on two coats of Hobby-
poxy-paint.
