Thank you soooo very much for the interesting, and informative note. I am so new to all this...your helpful suggestions are all new, being heard for the first time, and all are quite welcomed info'. I'll try the url you sent for the Weston pipe. Thanks also for the heads up about the oily mess. I never thought about that. I was refering to "cleaning up" the air flow path at the fan intake. It seems like Byron stacked everything right in front of the fan....appears to be a bad arrangement in terms of fan performance. Please do pass along anything else you feel may be helpful.
Happy flying...
