How to setup a brand new Wild Hawk

Hello all,

"Thinking out of the box"

There are people who have expressed an interest in how to best setup their Wild Hawk out of the box and there are those who complain that their Wild Hawk is a piece of crap and does not fly.  The information that both people need is the same.  There are several configuration updates of a stock Wild Hawk that are important to make it the good flying plane that people love.

This is what I would do to setup a brand new, out of the box, Wild Hawk:

Glue tail surfaces
While the double face tape used to secure the tail surfaces on the Wild Hawk is adequate and will hold the parts together for quite some time, it will come loose.  My recommendation is to just glue it up from the start and don't risk them coming loose in flight (yes, I have experienced this).

This shows the elevator flush with the end of the tail spar.
The first thing that needs to be done is to remove the double face tape.  If you skip this part, you risk your parts coming apart as your gluing will only be as strong as the tape.  Taking the tape off is not easy, but can be done with just your fingers.  Using tweezers would probably make this task much easier.  Now that all of the tape has been removed, its time to glue things up.  It's important to glue the elevator in first and them add on the rudder.  Take your time with this step and make sure the parts line up.  The elevator should line up at the tail end and not the front edge like it might seem.  If you don't line it up this way, you will risk the movable surfaces hitting they tail spar and not moving properly.

Re-position the battery
I don't know if it can be clearly seen in this photo, but the battery
us upside down.  It will be rotated counter clock wise and slid
forward as far as possible.
This modification require the removal of the foam ridge at the forward most edge of the battery.  This piece of foam it not that easy to remove but it can be done without too much trouble.  Once this is removed, the battery can be placed back in upside down and with the power wires still in the side cut out for them.  Since the Wild Hawk is notoriously tail heavy and does not have a proper center of gravity (CG), this is the minimum that must be done to make this plane flyable.  This does not resolve this plane's CG issues, but give you a good head start.

Don't install the landing gear
While you're learning, you will not need the landing gear.  Don't even bother installing them, they will just get in the way.  Just make sure that you are flying near a nice grassy area and learn to belly land your Wild Hawk there.

Tape up fuselage
This is an important step to help make sure that your Wild Hawk is as rugged as possible.  I have a whole post dedicated to this and it can be seen here: How to tape a Wild Hawk

Tape up wings
This is another important step as well in making sure that your Wild Hawk is as rugged as possible.  This step is also covered toward the end of the above blog post link.

Balance for CG
This is an important step in making sure that your Wild Hawk is as flyable as possible  I like my Wild Hawk leaning toward the nose heavy side and so I have my plane setup to balance at about 2 1/4 inches from the leading edge of the wing.  This is my CG and is just forward of the embedded wing spar.  A lot of people have theirs set for a CG of 2 1/2 to 3 inches from the leading edge.  This will require the addition of weight to the front of the plane.  I started by literally taping washers to the nose of my plane.  This worked fine and has worked fine for others that I know.  I decided to do something that I felt would be better and more permanent for mine.  What I did was to tape fishing split shot to my plane nose until the CG was right again.  Then I used my solder iron to melt some holes into the nose to hold the split shot.  When this was all in place, I used hot glue to secure it all.  I have a post here that shows how I did this: Weighted Question.  This post shows how I made a CG finder: CG Finder

Now your Wild Hawk should be very flyable and ruggedised.  If after all of this you are having issues flying this plane, the problems are not with the plane.

As usual, thanks for stopping by my blog and please post comments, good or bad.  Be sure to come back and check for future posts.
