Tailplane and Elevator
The tailplane is in two halves and must be inserted into the fuselage which has a pre-set
anhedral. Once inserted mark the film with a pen along the points at which the film has to be
removed. Once removed from fuselage remove film and re-install to ensure good fitment.
When happy with the fitment apply gap filling cyano or “wet assemble” with epoxy.
Remove the elevator from the hinges, cut away any excess covering from the hinge slots,
push the hinges halfway into elevator, then put two drops of thin cyno onto the hinge (at the
control surface), allow to dry. Gently push the elevator into the tailplane, when a good fit is
achieved (move freely) apply a few drops of thin cyno to each hinge, turn the tailplane over
and repeat the process.
Using the screw supplied and 5 min epoxy secure elevator mounting plate (D23) to the
fuselage behind the wing mounting bolt (see diagram 2) and drill and mount elevator servo.
Assemble the pushrods and joiners (see diagram 3). Push the rods through the tubes and
connect to servo, ensuring servo is in neutral position.
The pushrods will overlap the elevator, using this as a guide attach the control horns at the
same angle as the pushrods. Ensure that the front of the horn is flush to the chamfer on the
elevator, then drill and bolt in place.
Trim the pushrods as required, then push the metal rod into the pushrod. This is done easily if
you remove the pushrods from the fuselage and hold the metal rod in a vice or pliers and
screw metal rod into the plastic. Refit the pushrods then fit the snaplinks and fix to the control
horns.
Manually move the elevator by pushing the pushrod to ensure that they move freely (bend
metal rods slightly in the tube to facilitate free running).
Install the elevator hatch and mark out the center point at the rear of the hatch. Drill a hole
5mm from the rear of the hatch and through the tongue on the underside ensuring that the
installed elevator control system is not drilled or damaged. Secure hatch with screw supplied.
General Information
PLEASE NOTE:- We recommend you seal all round the edges of the covering with
Tufkote to ensure no covering will lift during high speed flight.
C of G; this should be 135 - 145mm from the wingroot.
Movements; Elevator 10mm up and down
Ailerons 8mm up and down
The MagnumR is very stable and likes long fast sweeping manoeuvres. We suggest you have
someone to launch the model for the first few flights until trimmed and you have become
familiar with the Magnum.
If fitted with the WEST EUROTEC .52 V1, you will soon have no problem in launching the
model on your own.
We suggest that for the first few flights you use an APC 9 X 6/7 prop, for you to get used to
the general feel of the plane. Then for ultimate performance use an APC 8 x 8 prop.
