Dear Builders,

While in Colorado Springs last month, I had a chance to crawl all over and 
fly John Wright's beautiful IV-P. A well built plane that truly motivated me 
to press on at full speed to complete something half as good. John was also 
infinitely patient with my many questions, and allowed me to photograph the 
details of construction and innovative techniques he used. A really positive 
experience and morale boost!

Almost concurrently, my teamming partner Jim White arranged for us to visit 
an in-progress project at Lakeland. This one is probably 6-8 months ahead of 
our own IV-P's and gave us another invaluable look at what was expected. The 
fellow who said a picture was worth a thousand words underestimated the value 
in this case! Thanks to the gift of a digital camera from my wife, we now 
have over a hundred pictures of what a Lancair looks like in "undress." 
Probably more offensive to non-builders than a full collection of baby 
pictures, but truly compelling to Jim and me. I'm sure that the two visits, 
with "documentation," will save us hundreds of hours in our projects. (To 
quote from a sage builder in Florida, "The things we've done really well on 
this project have been done at least twice.")

Our new Florida friends plan to relocate the hydraulic pump and resevior 
forward to the left side of the fuselage, opposite the accumulator on the 
right side. This idea is appealing to us as it moves considerable weight 
about two feet forward, shortens the run of hydraulic lines and provides 
limited access and servicing through the gear door without removing panels. 
Main disadvantage is that it occupies the left side of the forward "bucket" 
of the luggage compartment--a space my wife already refers to as "useless as 
a hat rack." I figure she won't notice the difference anyway!

Jim and I agreed at the start of our projects that we weren't going to 
re-think the engineering, and would stick to the plans as closely as 
possible, but moving the hydraulic pack forward to either the left or right 
side (over the accumulator) of the fuselage is really appealing. We'd surely 
appreciate any thoughts/comments on this. Recognizing the great variation in 
individual planes, does anyone have a good generic weight and balance spread 
sheet that we could use to estimate the impact/folly of this change?
