Subject: Re: Europa-List: Throttle Cables
|
| This subject is probably now yesterdays news but we had a lot of problems
| with kinked cables before I found out the problem. Unfortunately if the
| outer sleeves are not routed right, the cable in the throttle box kinks
and
| thats the end of it (ie: the cable has to be replaced). This is in my
| opinion a major weakness of this particular design.The first 6 inches of
the
| cables should be rigid and not flexible as in the current setup.
|
| We found the supplied cable sleeves (including the replacements) to be too
| long for our installation. This simply results in an unacceptable number
of
| bends and the inevitable jamming and kinking of the inner cable.
|
| Our best solution was to cut through the cable sleeves about 1 inch from
the
| carburettor ends and to cut out a portion of the outer sleeving. The
| remaining ends are then joined back together by gluing them inside a short
| alumiinum tubing sleeve (as found in model shops - brass would be ok too).
| An added advantage is that without the screw ends to get in the way, the
| cable outers can easily be passed from the tunnell end through the narrow
| gap between the undercarriage frame and the top of the tunnel. We found
this
| nearly impossible with the screw ends attached (NB they cannot be removed
at
| the cable ends).
|
| It is essential that the cables are routed in a very lazy S shape with no
| tight bends whatsoever (ie: straight out from throttle box, bending gently
| outwards & upwards, passing through top of tunnel then back inwards past
the
| carb filters to the carb attachment points). We used some strategically
| shaped tiewraps at the engine compartment ends to keep the cable paths
| exactly as we wanted them. Ours have to route outboard of the rotax
filters
| but this will be different if a plenum box is fitted.
|
| Having replaced two cables even before our first flight had always been a
| worry and we always look and check inside the throttle box as part of our
| pre start up checks to make sure there is no sign of kinking.
|
| However after 6 months flying and no problems to date we are confident we
| have got things right. Of course the occasional squirt of light oil helps
| too.
|
| Hopefully this hasnt confused too much.
