The recent messages on this list (for which I warmly thank you) made me
switch my vague opinion to a Lyc 200HP engine. Would an MT propeller =
work
fine with it? I'd like to keep things simple and safe for this =
airplane,
and I saw lots of complaints on propellers on this list. I wouldn't =
mind
picking a fixed pitch propeller either (to be honest, in our club we =
only
have fixed pitch propellers, so I have close to no experience with =
variable
pitch ones).

Soon after delivery of the 1st production run, DH will have a "Firewall

complete. Therefore, I wouldn't expect it to be a whole lot more

The first production run (awaiting delivery) includes many velocity =
builders
(not to mention all the prototype work to date), so there should be good
experience by the time your engine would be delivered.
If you need an engine in the next 12-18 months, then I would go with the
Lyco.

Dear Larry,
=20
I was and still am a strong supporter of DH engines. When I ordered my =
kit,
I was 100% sure that I'd install a DH engine in my airplane. In the
meanwhile though, after realizing how much time everything takes, I =
changed
my mind and decided to go for a standard and well-tested configuration.
There are many much more experienced builders than me who would be happy =
to
go for an inovation like that, because they have a much beter =
big-picture
than I do.
My hidden (from wife) plan is to finish this SEFG and then, while flying =
it,
to start building a new Velocity airplane, "the airplne of my drams", =
that
time as an "experienced" builder. That will definitely have a diesel =
engine
(also, I intend to eventually move back to Europe, where diesel is a lot
cheaper).

Subject: REFLECTOR: tools, tools, and tools again
=20
Dear Reflectorists,
=20
Thank you everybody for the valuable input on tools and the engine.
Following your advise, I'll most likely go with the Lycoming 200HP, when =
the
time comes. My original 160HP choice was based exclusively on range, =
but I
see the points you made, so probably in this case less range is OK for =
the
increase in power. I would still be grateful for an answer on the prop =
arc
diameter ... or is the general advice to use a little cap chain and not
worry about positioning?
=20
Regarding tools, I have just made another order with Aircraft Spruce;
another $200. I think I spent close to $2,000 so far on tools; I had =
almost
no tools when I started my project.
=20
For those who are just starting their project, please do not =
underestimate:
=20
1) the number and cost of tools that you will need for your airplane; =
better
be realistic than have surprizes. Of course, if you can borrow tools =
from
a friend or another Velocity builder that is great; but I am totally
isolated in a university city (Urbana-Champaign) and my friends only =
know
how to write computer programs and solve mathematical equations; never =
heard
of something called "pipe flaring" :-)
=20
2) the amount of extra-, initially unexpected time you'll need to spend
scratching your head or waiting for tools/materials. Give each =
subproject a
generous estimate, then triple that. I started fitting the pilot side =
lower
strake on January 18 and I was convinced that I would close the top =
strake
by the end of January if I give it all my time/energy. There were the
"unexpected" fuel senders, which slowed me down a few good days:
"unexpected" because they were not even mentioned in the manual, and =
slowed
me down because I had to order and wait for them, then learn how to =
install,
ask, etc. Well, now is Feb 4 and I still have to wait for the =
"unexpected"
finger strainers, the AN fittings needed for the change in plans, etc.
Assuming I receive these by Thursday and did not forget to order some
important little thing which will delay me one more week, then I may =
have a
chance to close the strake by the end of the week, say Feb 10. Applying =
the
reasoning above, that probably means Feb 18 or so, making it about 1 =
month
of work for one strake only. There is this Jeffco thing, though, which =
I
have never worked with and which has no proper webpage with detailed
explanations on how to use; I can only optimistically hope that there =
will
be no other "unexpected" issues with it ... though there always were ...

<p>The recent messages on this list (for which I warmly thank you) made =
me
switch my vague opinion to a Lyc 200HP engine. Would an MT =
propeller
work fine with it? I'd like to keep things simple and safe for =
this
airplane, and I saw lots of complaints on propellers on this list. =
I
wouldn't mind picking a fixed pitch propeller either (to be honest, in =

we only have fixed pitch propellers, so I have close to no experience =
with
variable pitch ones).<o:p></o:p></p>

Assuming I receive these by Thursday and did not forget to order some =

to
close the strake by the end of the week, say Feb 10. Applying the
