Strix StratoSurfer Quick Setup Manual

STRIX PNP StratoSurfer Quick Setup Guide

Battery: We recommend a 3s 3000-8000mAh battery. A smaller battery could be used, but will need

added weight to keep the CG at the recommended point.

Center of Gravity: The recommended CG on the StratoSurfer is 65-70mm back from the leading edge of
the wing; or directly on the main wing spar. Before flying, try to balance the plane on your fingertips
placed under the spar. If the plane is too nose heavy, try moving your battery further back until it
balances. Move the battery forward if the plane is too tail heavy. A tiny bit nose heavy is OK, but DO NOT
fly the plane too tail heavy, or you may experience poor flight characteristics.

Assembly:

● Tail Assembly

○ Connect the included servo extensions to both the rudder and elevator servos. You may

choose to secure these connections with tape to avoid coming loose inside the fuselage.

○ The horizontal stabilizer (rudder) should be laid flat on top of the tail with the servo facing

up.

○ Slide in vertical stabilizer (elevator) into the tail so that it seats well with the horizontal

stabilizer.

● Main Wing Assembly

○ Slide the spar into each wing half and gently push the two halves together until they are

about 25mm (1in) apart.

○ Uncoil the motor wires from the motor mount assembly and pass the motor wires down

through the wing halves in front of the spar. You will notice an opening for these wires to
pass through. Ensure that the wires are in this opening, and slide the wing halves all the
way together.

○ Place motor mount assembly on top of the wings and align bolt holes. Slide two 50mm

bolts through the front two holes, and two 40mm bolts through the rear two holes. Slide
these bolts through the main wings.

○ Place this wing assembly on top of the fuselage, put the ESC and wires in the fuselage,

and thread the bolts into their receiving holes. Ensure that no wires are being pinched
and tighten until snug.

○ Install propeller with appropriate ring adapter and with the letters forward.

● Optional Forward Camera Mount

○ Included in your package is a small wood plate that was intended to be placed either on

top of or below the flat part of the nose if you want to use a pan/tilt setup with a 9g servo.
Center the plate on top of the nose and trace the hole for the servo with a fine point
marker and cut out with a hobby knife or razorblade. Then use small screws to attach the
plate either on top of, or inside the fuselage.

Maiden Flight - Elevator travel should be around 10mm up and down. Rudder and ailerons can be
15-20mm travel in both directions. Use neutral/level control surfaces for the first flight. You may wish to
add few clicks of “up” trim in your radio until the plane is comfortably airborne. It is usually best to have an
experienced RC friend launch your StratoSurfer for the maiden flight, however it is very easy to throw by
yourself if you have previous experience.
