needed for an electrical connector, and fix the grommets
to the bypass with a small drop of thin CA.
Inlet Joiner:
The pre-painted inlet ducts are factory-installed, and only
the back end may need trimming a little to exact length to
fit the fibreglass inlet joiner. The inlet joiner is joined in the
factory for you, and has 2 reinforcing ribs laminated into it
during manufacture to ensure that it cannot be sucked flat
by the turbine. Check the fit over the back of the inlet
ducts. Included in the hardware pack is a length of 1" wide
fibreglass band, and you can apply one wrap of this
around the back of the inlets if necessary to get a nice tight
fit of the joiner over the inlets. Sand the outer surface of
the inlets, clean, and apply the band with slow (24hr) lami-
nating resin and sand smooth when cured.
The back of the inlet joiner fits inside the moulded flange
at the front of the the bypass duct. Trim the inlet joiner
length to fit exactly. After final trimming to length, apply 1
wrap of the fibreglass joining tape around the back edge
with laminating epoxy for a nice tight fit inside the bypass
duct. The flange on the side of the inlet joiner needs to be
notched at the back so that it just clears the front of the
bypass, but stops the inlet joiner moving backwards dur-
ing operation. (photo right)
Now you can make all the tube and electrical connections to your turbine, and secure them to
the fuselage on the opposite side to the extension cables from your rudder and stabiliser ser-
vos, as shown in photos P6 and P7.
Important: Whatever make of turbine you install, please read, and follow, the manufacturers
instructions and recommendations before installing your motor.
