Panic History
Philip Newman designed the Panic Biplane over 25 years ago for fun-flying and competition flying.
The original design used a dihedral lower wing with ailerons and an independent flap on the upper wing.
This setup was very popular with new pilots as it gave a very smooth, yet responsive, feel that was in
a class of its own and inspired pilots with confidence. With a few modifications, including a flat bottom
wing, ailerons coupled top and bottom, the Panic biplane was now competition hungry and one of the
most advanced aerobatic aircraft of its time. Over the years the Panic has won more then its fair share
of competitions, be it spins, loops, rolls, touch & go’s, climb & glide, or freestyle aerobatics. This model
does them all with ease which has earned it the tag of being a pilot and club favourite over the years. It
has been displayed at many a flying show by the infamous Panic Team U.K. They add their own legendary
flying skills and chaos to their well-rehearsed flamboyant flying routines to induce many a ooohhs and
aaaahhs from the crowd as they appreciate the havoc like display! Over the years the Panic Team have
used modified Panics to entertain the crowds, including a releasable top wing (you need two pilots for this
one!) The model flies around and at the click of a switch, the wing is released (at first sight you think the
plane is in big trouble but don’t get the black bin bag out yet!), and with the help of some servos, battery
and receiver, the wing is able to fly around with a few aerobatics thrown in for good measure then land
back down on the patch. This always entertains the crowd!
Another crowd favourite is the backward flying panic, that’s right, “BACKWARD FLYING”. This was the
hardest of all projects to achieve (you wouldn’t believe where the C/G has to be to keep this model in the
air!) but with the tenacity of Robert Newman and a pile of broken Panics, he did not give up until he had
overcome all obstacles and had a flying specimen, well done Robert! To add to these eye bogglingly
crazy antics, Robert and the team went at it again and created a Panic that is hand launched and, when
released, (a bit of acting is needed here with a little trip when the model is released by the helper to help
give the crowd the feeling that a deserter is imminent) the back half of the fuselage falls to the ground
leaving the remains of the Panic to entertain the crowd. These guys are crazy!
As you can see, the Panic is probably the most fun you can have in the air!
“Another world first”. The Panic is the only model that can land on demand in a full power-on flat spin!
You need to see this to believe it!! The Panic Team have always tried to find new ways to mass land when
performing at shows and with the flexibility of the Panic and inventiveness of the team, mass landings
such as mass inverted landings, (sometimes landing on top of each other), hand catching (cut the engine
first!), and the power-on flat spin was invented. In most cases, the engine would still be running after the
landing so after a quick check of the controls, take-off and have another go.
The Panic aircraft was designed by a pilot and over the years has evolved with the help of pilots, for pilots,
to give them the unique and ultimate flying experience that not many models can give.

Assembly and Installation
Step 1 Assemble and install the main landing gear and wheels
Figure 2. Assemble and install the main landing gear and wheels
▼ 1. Locate the undercarriage so the thicker wire is facing the rear of the model.
▼ 2. Use the 4 aluminium saddle clamps and 8 M3x8 screws to fix the main landing gear onto the
fuselage as shown.
▼ 3. Install the main wheel on the wheel axle (L&R) and fix each wheel with the collars supplied.
Step 2 Install the tail skid onto the bottom side of the fuselage tail-end.
Figure 3. Install the tail skid
5
Step 3 Install rudder horn (L&R) and hinge rudder to the fin
Figure 4. Install rudder horn and then hinge the rudder to the fin
▼ 1. Install control horn (L&R) onto the rudder. A small amount of the rudder horn may need to be cut
away to allow for more left and right movement.
▼ 2. Apply CA to glue hinges into the rudder and the fin. Make sure that the rudder moves freely.
IMPORTANT
To achieve maximum movement (up to 80 degrees) on the rudder it is necessary to fix the rudder horn so
the clevis holes are 5mm behind the hinge line.
Step 4 Install the elevator horn and glue the hinges to the stabilizer
Figure 5. Install elevator horn and hinge it to the stabilizer
▼ 1. The elevator horn must be mounted slightly off centre, allowing the push rod to pass one side of
the vertical fin post.
▼ 2. A small amount of the elevator horn may need to be cut away to allow for more down elevator.
Check movement each way and trim if necessary.
▼ 3. Fit the elevator push rod using the metal link at the elevator end and the bent wire with a swing
keeper at the servo end.
6
Figure 6. Using the metal link connect the push-rod to the elevator horn
Step 5. Glue the complete tail surfaces in place
IMPORTANT
Make sure the tail plane and rudder both dry fit in position before gluing in place and the rudderpost is
90 degrees to the tail plane, otherwise you will not get the 80 degrees rudder movement needed in both
directions.
▼ 1. Use epoxy glue to glue the tail plane and fin in place. An adequate amount of glue should be used
on the bottom of the fin to secure it to the inside of the fuselage. (Figure 7).
▼ 2. Install the rudder servo and connect the rudder pull-pull control system. (Figure 8)
Figure 7. Glue the tail plane and fin in place
IMPORTANT
The rudder servo fits in the cut out in front of the rudder post. The pull-pull wires will go slack when
the rudder is not in the neutral position. This is normal. Ensure wires can move freely and do not foul on
either the rudderpost or the rudder servo.
ELECTRIC OPTION
If you are building an electric version you may wish to move the rudder servo into the now redundant
throttle servo location and use a longer pull-pull system. This will help the C/G.

▼ 2. Maximum rudder movement recommended for advanced pilots
Step 6 Install engine and fuel tank
▼ 1. You can use either a pair of L&R engine mounts or a solid round engine mount as shown in Figure
9. Firstly fix your engine onto the mount with 4 M4x25 screws and M4 self-lock nut.
Figure 9. Engine installation
▼ 2. Place the mount along with the engine on the firewall and rotate around until the silencer runs
underneath the fuselage and as close to the centre as possible.
▼ 3. Mark the position of the 4 fixing holes on the firewall
▼ 4. Remove the engine mount. Drill 4 holes in the firewall for the 4 M4x20 bolts and insert them
through the firewall.
▼ 5. Fit the 4 blind nuts behind the firewall and tighten to secure the engine mount in place.
▼ 6. Fit the fuel tank in place behind the firewall. (See Figure 10) make sure the tank is secure and
cannot move.
8
Step 7 Installation of radio
▼ 1. Glue the factory ready-made servo tray in position.
▼ 2. Fit the throttle and elevator servo as shown.
▼ 3. Connect one end of the throttle control cable to the engine throttle arm, the other end to the
throttle servo arm. (See Figure 10.)
▼ 4. Install the battery.
▼ 5. Install the receiver.
Figure 10. Radio installation
REMARKS
The battery charging lead can be mounted on the outside of the fuselage using any number of readily
available mounts. This will assist charging and battery monitoring without the need to remove the wing.
The On/Off switch can be mounded on the side of the fuselage or as shown using some pull/pull wire
running through each side of the fuselage.
The battery position may need to be moved to obtain the correct C/G. This can depend on which motor is
used or the weight of RX battery pack being used.
