What makes FPV Race Drones, quadcopters, or quads fly the way they do? In this
video I'm going to answer that question to give you a better understanding of
what's actually happening with your quad when you move the sticks on your
transmitter. By understanding your quad's responds to your stick inputs you'll
become a better FPV pilot and learn new tricks and maneuvers more quickly. This
is also Episode #1 in a short series of videos to help introduce you to the FPV
hobby where we lay the foundation for you to start and continue on your "Journey
the Better" FPV fun, flights, and racing stuff! It's our FPV Boot Camp! Where we'll
go over how quads fly, the different parts and components of a quadcopter and
what they do, so you can eventually make your own custom build and we'll also look
at the main types of gear you need for this hobby as well as what their
functions are and some of today's best value options. We may even have some time
at the end of a couple of these FPV boot camp videos to have a little fun with a
flight or two. This boot camp mini series is designed to help you get started with
FPV the right way and make a well- informed decision as to what FPV gear is
best for you so you can save both time and money and have more fun sooner! Plus
we'll be giving away one free enrollment to our Fast Track FPV Course which goes
into much more depth of not only these topics but everything you need to know
to get started in this hobby the right way. It also includes a discount code
which can be used multiple times for a big discount on gear purchases for the
remainder of 2019. To qualify for the giveaway either for yourself or someone
you know, make sure to check out the rules in the description below. Let's
kick off our FPV Boot Camp! We're gonna use this diagram to depict how a
quadcopter flies. The motors on the quadcopter spin and each motor turns a
propeller or a prop. There are four of them and that's why it's called a
quadcopter. The diagram down here at the bottom shows the normal spin direction
of each of the motors. Motors #1 and #4 normally are set up to spin
clockwise, whereas motors two and three are
normally set up to spin counterclockwise. They spin in different directions just
to balance each other out otherwise this whole quadcopter would be spinning not
just the motors! When the props are spinning parallel to the ground they
force air flow downwards which thrusts the quad up as long as the thrust is
sufficient to overcome gravity. The previous diagram showed when the quad's
props are parallel to the ground how it gains altitude but
in that orientation it's not flying forward at all which isn't much fun. For
forward flight (in the direction you're looking when flying FPV) the quad needs
to be angled (or pitched) forward. The quad makes this happen by spinning the rear
motors faster than the front motors based on your transmitter control stick
inputs. In this example, the rear motors are spinning faster than the front
motors so the quadcopter is going to be angled (or pitched) forward. Here the
front motors are spinning faster than the rear and the quadcopter will pitch
backward. To bank (or roll) left the quadcopter's right motors, motors #1and #2
need to spend faster than the motors on the left hand side and to roll right the
motors on the left (#3 & #4) need to spin faster than motors on the right.
For the quadcopter to look (or yaw) right, motors two and three need to spin
faster than motors one and four. Whereas to yaw left, motors #1 and #4 need
to spin faster than motors #2 and #3. In this orientation we saw earlier with
a quadcopter pitched forward, the airflow is no longer being directed entirely
downward. There are both horizontal and vertical components to it which also
means that there are both horizontal and vertical components to the thrust. Since
some of that thrust is no longer being directed upward, in order to maintain the
same altitude when in a pitched forward position as that of when it's parallel
to the ground, more airflow will need to be applied in the downward direction
which means you'll need to increase your throttle stick input. Now when you do
that you're also increasing the thrust in the horizontal direction which means
you're gonna be flying forward faster. In this pitched forward orientation you
don't want to be looking to the ground while you're flying forward. You want to
be looking horizontal to the ground in the direction you're flying so you can
actually see where you're going because the view of the FPV camera is the actual
view you're seeing in your goggles. This means you want to have your FPV camera
angled upward in the quadcopter frame at the same angle your quadcopter will be
at while flying forward. Remember what we just mentioned, that the greater
the quadcopter is angled forward the faster you're going to be flying forward.
This is going to be the same angle as your FPV camera so the angle you
place your FPV camera in the quadcopter frame prior to flight (before you
actually start flying) is directly proportional to how fast you will be
flying. When you first start out learning FPV you want this camera angle
relatively small on the order of about 5 or 10 degrees. As your skills increase
however, so will your camera angle and your flight speed. Let's see if we can
put some of this stuff into practice and have some fun. But before we do make sure
