Electric Trim
The pylon must be folded down to inspect the motor assembly. The fairing must be removed to inspect the
bungee etc.
The electric motor assembly and contacts should be kept protected from prolonged contact with moisture,
otherwise no specific maintenance is required.
The trim cords should be checked for fraying or degradation especially at the winch drum, engine mount
guide, top pulley and end connections. If required it must be replaced with genuine Dyneema 4mm cord, part
no. TCL-001 and TCL-002. Note the top cord is of a fixed length with sewn ends, it must not be shortened by
knotting etc. The 5mm return bungee should provide enough tension to wind the cord neatly onto the winch
drum with the trim cord slack.
The pulley must turn freely and the ball bearing should be given a drop of oil.
Adjustment
With the control bar held back against the pilot's stomach, in the fast trim position, the trim cord and bungee
should be just coming under tension. With the bar at the pilot's stomach, the cord should be just slack.
Adjust by pulling the trim cord through the winch spindle and applying a stop knot.
With the trimmer set to the slow position, the trim bungee thimble knot must not be pulled lower than the
pylon fairing spacer. Check the basebar can be pulled fully back against the bungee tension.
At slow trim, the trim bungee should provide a force of 13-16 kg measured at the control frame basebar, with
the basebar against the front strut. If the force is less than 12kg and the slow trim speed is too high ( above
60mph) then the trim bungee must be replaced with genuine part no. BNG-001.
Display
The display should indicate from full up to full down, in the correct sense, over the whole range of trim motor
movement. It can be adjusted if necessary by preset potentiometer at the back of the display. Note display
readings may be affected by over or under voltage conditions.
