1.9 Remote glowplug connection
(bag U2-6)
Work out the best position for the remote glowplug socket to suit your model, and fit the socket
in one of the two holes in the switch console, or in the hole in the left-hand sub-structure side
frame. Fit the solder tag, washer and nut on the socket in that order, and tighten the nut to
secure the socket.
The socket can now be connected to the motor using the twin-core cable supplied. The
crocodile clip is designed to provide easy access to the glowplug in order to fit a new one, and
the clip should be soldered to the wire running from the centre contact of the socket. Attach the
crocodile clip to the glowplug, and fix the other wire to one of the motor mount screws using an
additional washer. Deploy the cable neatly, then solder one wire to the positive terminal of the
socket, the other to the negative terminal.
1.10 Silencer
Select the appropriate exhaust manifold to suit your motor, and install it in such a way that the
exhaust runs below the motor, and is directed towards the rear inside the sub-structure. Thread
the tuned pipe silencer through the rear bulkhead 4450.18 from the rear, and connect it to the
manifold using Teflon hose and hose clips; leave about 5 mm clearance between the manifold
and the silencer inlet stub.
The method of supporting the silencer tailpipe varies according to the silencer used. An exhaust
holder (e.g. ULTRA-STAR 2000) can be used at the rear end to support the tailpipe, or it can be
supported at the fuselage exhaust outlet or - preferably - by means of a console (available
separately, Order No. 4450.149). In this case the silencer is supported at the centre, and
secured by tightening the clip provided. Take care not to overtighten the clamping screw.
In this case the two brackets 4450.26 should be screwed to the sub-structure at a suitable
position, using the existing holes as reference points; note that the actual screw positions may
have to be located differently to suit your silencer.
