| Subject: | Re: Instrument Panel Advice re placement on Firewall options |
In 20 years, I've never needed an isolation mount in a Europa. That said, if you
install a 5 cylinder radial for an engine, or you operate off of a washboard
for a runway, you may need some. If you can drive your wife's car on the runway
without pain or suspension component failure, you'll be fine.
Today's solid state components coupled with the smooth running of the Rotax or
Jab engines, and a balanced prop, pretty much makes isolation mounts a thing of
the past. Back in the day of spinning gyros and 10 pound instruments I could
see it.
Heating is more of a problem with a sealed plastic panel which holds in the heat
like a thermos bottle. Please put in a fan or similar to pull the radiated
heat from the sun out of the panel.
Today's solid state equipment draws 60 milliamps and don't create heat but the
screens do get warm in some components. Especially common in the Dynon Skyview
first gen. GRT and Garmin stay somewhat cool. However, a small computer fan
on the bottom of the panel and one on top keeps the panel interior at cockpit
temp which is good enough.
Always follow the radio manufactuer's recommendations on older salvaged radios.
Most older Garmins, like the 430 need an instrument fan.
Keep the panel interface simple and easy to remove. It pays dividends later on.
As far as cables, read my technique article on my website on the throttle and choke
cable etiquette. Repairing cables is not worth the cost or time. Any good
bike shop can normally make a new set of cables.
