A
Look at My Project!...
N351DPs early water tests
1/2009 Well I almost have the plane to its
100 hour mark. So far everything seems to be going AOK. People
ask me if there were anything I would change about the plane and I do not
think I would do things all that much differently. Like any airplane,
I wish it were lighter, went faster, went further, and carried more, but
all things considered the plane does a nice job of what is asked of it.
I suppose if there is one item that could use a bit of work it is that
the plane needs more Yaw stability. If I get to the point where I
have the extra $$$ around, I will probably invest in a yaw damper.
S-tec makes a nice one, but S-tec has recently been sold, hopefully they
will continue the product. I still need to try a few other tricks
with the vortex generators. Other items that could be done to improve
the Yaw issue is to enlarge the Vertical tail or try to move the CG forward
and unsweep the wings, but it seems that most of the solutions involve
some fairly large re-design efforts. I have also found that the Yaw
issue is slowly moving down the list as I get better at flying with my
feet. I still hope to make some incremental improvements to the issue.
BTW some, including myself, have proposed extending the cabin to help move
the CG forward. I now think this would only amplify the yaw issues
by adding more side area forward of the CG and that the cabin could not
successfully be extended without also extending the tail area aft of CG
and increasing its surface area. This spring I am hoping to devote
to becoming more proficient in the water ops. The plane has been
on the water numerous times but I still have not Docked or ramped it.
I need to practice these exercises if I am ever to become a master of my
ship.
Enjoy the photos!
The following chapters are a basic attempt to re-document almost ten years
and over 7500+ hours of building, I have had a lot of encouragement
and positive feedback about this website. But the truth is I really
prefer NOT to spend the free time at the computer.
I have listed the chapters in the rough order my Aircar was constructed.
The later chapters tend to be better documented than the earlier ones.
PLEASE DO NOT CONSIDER THIS A BUILDERS GUIDE. Each aircar project
tends to have differences reflective of its builder. This is especially
true of such a large project, built from plans that were drafted over thirty
years ago. This is my first project and I have kept it a goal to
stay close to the plans. However I have re-engineered those items
not clear on the plans, and taken advantage of some techniques that have
become more accessible over the last twenty years including: modern epoxies,
carbon and Aramid fabrics, vacuum bagging, powder coating, industrial heat
treating, etc.
The project has been built using the most current set of plans, that is
for model S-12-E. I do, however, have a set of older plans (S-12
B,C) that I have found very useful for some items. I have tried to
document and clarify any items that were not clear (to me) on the plans.
My goals have been: #1 Build it SAFE, #2 use the best materials available
to build it STRONG, #3 Keep it SIMPLE, #4 Keep it STRAIGHT.
Please feel free to contact me through the Yahoo Group if you have any
questions.
* to make web maintaince easier, the
later chapters now have seperate photo galleries
