Fellow RV-ators...
Here's a little "heads up". I noticed on my plan #16 (-6a) that a 14" dimension for aileron tip to rear spar
measured at 14.125 on the "full scale" plans. Bruce over at Van's correctly pointed out that one should not
scale directly off the plans unless instructed to do so, as plans may shrink or enlarge depending on the
reproduction process. So don't be taking a ruler and slapping it down on the plans and then use that
dimension. Use the stated distances on the plans. Just a bit of info, hope it helps prevent grief.

I just got off the phone with the tech guy... I was mumbling that the AD4-4 rivets for the HS411 bearing assembly are not long enough and the shop heads are below minimum height, and they should be using a ~4.5 length... He said that they know it, but the -4 rivets are what they use for any HS411 assembled at the factory, and that that even with the thin shop heads the part is 400% overbuilt, so "don't worry"..
It would be nice if they communicated that on the prints..
And it would be nice if the prints were to scale so you could measure directly, and it would be nice if the HS702's didn't have extraneous holes in them from the RV8 production parts, that make you think the drawings are wrong, etc....
And it would be really nice if the assembly print (#3 drawing) for the HS702 was even close to engineering drawing standards so that it doesn't take 30 minutes of muttering and mumbling to figure out what the heck they want you to do...

Denny - I'm thrilled with the completeness and workability of the plans and the pre-drilled parts with my Vans kit. It is the best on the market by far!
I have to admit that I have moments where I am challenged to a great degree and I (like you) have found a way to get the answers. I (like most builders) have established a network of other builder friends, EAA local chapter members, builder websites, videos, and inspection of completed RVs to get me through to the day when I get to be a test pilot!
We are building an experimental aircraft from a kit! That's what is so gratifying about it. With our pre-punched kits we are soooooooo much better of than all those two or three thousand builders before us. I am a very happy Vans builder.
Keep on building and we can say hello at Van's homecoming in the future.

It would be nice if plane came already assembled, as
well...seriously, what you have in front of you is one
of the best in the industry. Trust me on this! There
are sooo many other airplane kits out there that their
plans are a poor excuse for mechanical drawings.
There comes a point during construction when you
realize that "you are the builder" not someone who is
putting together one of "Van's" kits. You will be
able to make decisions that stray from the plans or
directions, without calling the factory. I think for
the last two years, I didn't call the factory at all.
I just did what it took to get it done. It is a kit.
It is designed to make the builder build 51% of the
airplane. It can't be too simple, or there would be
no "education" (as the FAA calls it) for building an
airplane.
There are many ways to improve on Van's drawings or
instructions, but believe me, you have it made
compared to the RV-3,4,6 and early -8 guys. Trust me!
Be happy with what you have, look at other airplanes
and figure it out. It WILL come together and you WILL
get better. As I said, you will get to the point
where your interpretation of the drawings and manual
is what counts.

Paul is right.
I'm about one class away from having a certified CAD CAMM degree.
Vans put a TON of work into creating these plans on CAD. They are
very well done and well thought out.
Keep in mind that in order to draw in CAD you have to enter the EXACT
sizes of the parts. You just can't draw it with a pencil kind of
close to what it looks like. This means someone spent countless
hours in front of the computer, entering each part one at time after
measuring or desiging them. But, now that they are drawn in CAD any
mistakes can be fixed quickly.
I have more experiance reading mechanical drawings than most builders
do, so I have an advantage in my ability to understand what they are
trying to get across. You are the builder so it stands to reason
that you should be able to read a print. Just like a foreman on the
Boeing shop floor!
