Installing the optional aero-tow release (*)

This is also a good time to install the aero-tow release (if required). There are a selection of
purpose made aero tow release mechanisms available commercially for which installation
techniques vary, but the simplest form is described below:
Carefully mark out and cut a 10mm slot about 2mm wide transversally about 5cm from the
nose and with the lower third of the fuselage diameter. Using thickened epoxy, fix a length of
PVC Bowden cable outer along the inside of the fuselage such that it intersects the slot at 90
degrees. The slot should be positioned so as to allow at least 5-10mm of the PVC tube in
front of the slot.
Fig 1. Aero-tow Release
Once the resin has cured, cut away the Bowden cable outer from inside the slot and insert a
length of 0.8mm steel wire inside the PVC tube such that it engages both sides of the slot
when closed and is clear of the slot when open. Connect the free end of the steel wire to a
suitable servo to operate the aero-tow release. You will require a simple loop, best made
from monofilament nylon to link up to the towline.

Completing the canopy.

The Carbon canopy is supplied ready made, requiring only minimal finishing. Place the
canopy on the fuselage opening, carefully check the joint and adjust as necessary for a
perfect fit. Minimum gap and good overall appearance will be your just reward for a little extra
time and effort at this stage.

Installing the canopy catch.

The forward canopy pin is held in place by the channelled hardwood support. The support is
glued to the inside of the canopy at a position about 15mm inboard of the forward canopy
opening in the fuselage, using thickened epoxy. Be sure to roughen the inside of the canopy
with abrasive paper before gluing to ensure a good bond. The canopy pin is likewise glued
into the channel in the hardwood support – such that the pin protrudes about 15mm from the
front of the support to engage with the rim of the fuselage opening. Once cured, test fit the
canopy, and use a 3mm drill or suitable round file to form a recess in the forward rim of the
fuselage opening to accommodate the canopy pin. Re-check and trim carefully until a perfect
fit is achieved.
The rearward canopy fixing is made using the GRP leaf-spring which is bonded to the inside
of the canopy and held in place with a small piece of fibreglass cloth and some epoxy. Again,
be sure to roughen up the inside of the canopy with abrasive paper before bonding the leaf-
spring in place.

Installation of the all-flying tail plane.

The elevator bell-crank is factory installed in the FLAMINGO and FLAMINGO Elektro. This
system has proved entirely effective in many of our models over a long period of time and
ensures a secure connection with no unwanted slop in the control.
