Engine Bearing Air Scoops

[patterndude at attbi.com]

Randy,
Be careful of your info.  That may appear true in cooler areas, but in TExas 
the WEbras can't be idled long on the ground or they will over heat and die.  
Then it takes a long time for them to cool enough to run them.  It is common 
for owners to keep the engine at mid throttle while walking it out to the 
runway just to keep it cool before takeoff.  THis is not necesarily a major 
problem as long as you deal with it.
