Most of us are familiar with the term "Flutter". For those of you who aren't, it is when a surface or control surface of an airplane suddenly and often violently vibrates, frequently resulting in a catastrophic failure. However, the more I read and talk to others, the more I realize how little this phenomena is understood. With that in mind, I hope to shed some light on this subject and hopefully, dispel some myths.
I was never big on using stands. I've had
a few of those Styrofoam things, and I've
cut some half-rounds out of a cardboard
box or two, but I rarely ever kept one for
very long. Then, a few years ago, I bought
a plane at an auction that came with a homemade
PVC stand. I eventually sold that plane,
but the stand was so handy that I held on
to it and have been using it regularly ever
Lot of folks have asked questions about
smoke systems, and after fooling around
with them for a few years, I thought I'd
let you in on a few of the basics. Maybe
it will help you to avoid some of the failures
that I have gone through.
With the advent of quality ARFs in recent
years, we have seen a huge influx of new
people to the sport. Inevitably, many of
you eventually decide to try your hand at
building. Most are very successful while
some others are not. Some of the more successful
builders choose to build many more kits
while others got the building bug out of
their system the first time.
truth of it is, building is not for everyone.
When asked, "Is this a hobby or a sport?"
my reply is, "Flying is a sport, building
is a hobby" and there are many people
out there who have neither the time nor
patience for a hobby (or find they are lousy
builders and would rather collect stamps).
a CLOSER look at CA Hinges!
The very first "How-To"
article I did for RCUniverse was on installing
CA Hinges. The article was very helpful
to many people, but while it showed the
proper way to install them, it fell short
of explaining what not to do and why.
we are going to go a little more in-depth
this time and explain the do's and don'ts,
the why's and why-not's and hopefully give
you a better understanding of just what's
going on inside that simple, yet complicated
are one of those things that we veteran
fliers usually take for granted, but that
can be very frustrating to the beginner,
so here is an article that will hopefully
answer many of the questions the beginner
might have about setting up a tank.
to Build a Sanding Box
I have always tried to do my major
sanding projects outdoors. It always seemed
to work out well time-wise in that, I would
usually get a new plane for Christmas, and
by early spring, when the big sanding jobs
came along, the weather would be tolerable.
But several things have changed since I
lived in New York. For one thing, Minnesota
winters are much longer, and nowadays once
spring arrives, I'm so busy doing product
reviews that my own projects get sidelined
until the weather gets cold again.
should I start out?
One of the questions we hear most
often on RCU is, "How should I start
out?" We wish there were a simple answer
to this, but the fact of the matter is,
there are so many different ways that it
can boggle the imagination. So, in an attempt
to unclutter your mind a little, here are
five things for you to consider before purchasing
your first or next airplane or piece of
- Budget - Time - Facilities - Personality
let's take a brief look at each item.
a Leading Edge
Unfortunately, it's not all that uncommon
- You were coming in for a landing and clipped
a tree, or a pole, or some other obstacle
and now your wing has a nasty gash in the
leading edge complete with a few broken
rib-fronts. Now you're wondering what to
How to Another Look at Covering
"What's the secret to a good covering
job?" That's a question that has been
posted many times here at RCU. A few years
ago, I did a basic tutorial on covering,
but it was just that? Basic. So when it
came time to cover a wing I recently finished,
I decided to videotape the process to give
you a more "In-Depth" look. But
first, let's go back to basics.
It seems that lately we have been getting
a lot of questions asking if it is correct
to balance a low wing plane upside-down.
The simple answer to this is "Yes",
but a more accurate answer would be "Usually,
but not necessarily always". Once you
understand the basic principle, you'll easily
beginners guide to Soldering!
Lots of folks at RCU have had questions
about soldering, so we thought we'd give
you a "How To" on the basics.
If you've never had to cut into a sheeted
area of your airplane, consider yourself
lucky. But at some point in time, you will
probably find it necessary to do so.
Lots of you have asked about balancing your
airplane. So let's start by answering a
few frequent questions, and then we'll show
you how it's done.
This seems to be one of those things the
sends chills up the spines of people who
either have never attempted it, or have
attempted it with poor results.
CA hinges have been the topic of many discussions
here at RCU. It seems that everyone has
their favorite way to install them, and
there are many people who won't use them
anymore due to problems they have encountered
with them in the past.
