    Disclaimer: this is not a toy. This is a high-performance miniature aircraft, capable of high speeds and damage to life, limb, and property. The manufacturer and its distributors cannot control how you assemble this model, what equipment you use to fit it out, or how you fly it, and can assume no li...

    Airplane, so take the time to do things right. Or redo them if they are wrong. Careful work will result in a long- lasting plane that gives you years of pleasure, one loose component could result in the complete loss of the aircraft and all the components inside it, and someone can even get hurt. So...

    Consider it a great investment, the glue is the best you will use. One cartridge is plenty to assemble your aircraft. C. Working with pneumatic systems: the t45 uses pneumatic brakes and retracts. If you follow a few tips, you should have very reliable, leak-free operation. Neatness counts. All airl...

    Notes these instructions were written based upon the prototype kit from the fei bao factory. Please note that the kit and components may have undergone changes through the production process. Center of gravity and control surface throws were confirmed as a good starting point through limited flight ...

    Air systems remove the nose gear from the aircraft. Using a matchmaker or a receiver and your transmitter, center the nose steering servo and attach a heavy duty steering arm. Bolt in the nose gear steering servo as shown in the photo. Do not use the rubber mounts and brass eyelets. Loctite the bolt...

    The receiver may also be installed on this board. As the three main gear all retract forward, you may wish to provide more air to each unit. To accomplish this, set up the nose gear on one air valve designed for large scale aircraft and supply air to the mains from a second, separate valve. Use sepa...

    Horizontal stabilizers using a matchmaker or receiver and transmitter, center both horizontal stab servos. Install the servo arms such that they are matched as closely as possible for both servos. Option: for added security, use metal servo arms for this application. If you use a tapped metal servo ...

    Using a cutter, open up a small hatch above the servo opening on the upper rudder mount platform in order to access the servo arm. See photo. Make up two servo linkages of exactly the same length. Install linkages on to the servo arms and bearing box control arms. Check to make sure horizontal stabs...

    Vertical stabs and rudders begin by gluing rudders into vertical stabs as follows: fill the hinge point holes in one vertical stab with a generous amount of aeropoxy. Insert rudder. Install vertical stab into the fuselage and temporarily tighten mounting bolts. Move the rudder inward to the point wh...

    Open up the slot in the rudder with a small cutter and dremel tool for the control horn. Be very careful not to cut through the rudder as you enlarge the slot. Optional: paint the control horn to match your color scheme. Tape around the slot with low grip masking tape and fill the slot with aeropoxy...

    Wings fill the hinge point holes in the flap leading edge with a generous amount of aeropoxy. Insert the flaps and press forward to the point that you achieve approximately 45 degrees of throw. As you did with the elevator and rudder servos, find center and install servo arms in horizontally opposin...

    Open up the slot in the flap with a small cutter and dremel tool for the control horn. Be very careful not to cut through the control surface as you enlarge the slot. Optional: paint the control horn to match your color scheme. Drill the control arm for the ball end bolt. Start with smaller wire siz...

    Engine installation if you haven’t already removed the engine hatch covers, do so now, labeling each side. Completely straighten the taps on each side of the pipe. Note that the tabs are closer together on one side, this will be the “bottom” of the pipe, though it will be oriented “up” as you work o...

    Position the engine on the mounting rails. If need be, make a supplemental mounting plate if the engine tabs do not completely span the gap between the rails. Confirm that the engine to pipe clearance is set at manufacturers specifications, drill and bolt the engine to the rails. Check the angle of ...

    Cut a valve/pump mounting plate out of scrap ply, approximately 2 inches wide by 6 inches long. Mount components as shown in the photo. Make a mirror image arrangement for the other side. Using velcro, temporarily position plates in the wheel bay, making sure that there is adequate clearance when th...

    Temporarily position the intakes in place to make sure you have clearance. See photo. Once everything is in place to your satisfaction, mark the pickup and vent fixture positions. Remove the tanks, plumb, leak check and reinstall. Drill fuse for vents and plumb. See photo. At this time, permanently ...

    If you are using uats, it is recommended that they be positioned in the forward fuse, flanking the nose gear cylinder. Make a platform as shown in the photo and affix to the forward former with a large piece of industrial velcro. Disassemble the main tank stoppers and check for kinks, obstructions a...

    The ecu batteries fit nicely into the pockets on either side of the forward main tank. Wrap them in foam and insert, padding with extra foam as needed. Watch wiring and air lines. Install and plumb main tanks, running pickup from aux tanks to the vents of the mains, and the pickups from the mains to...

    Completing construction glue ventral fins in place. It is recommended that you faintly draw the outline on the fuse and then drill a number of attach holes for the glue to use to “pin” the fin securely in place. Make sure the fins are positioned at equal angles. Use a straightedge as shown to check ...

    Throws and cg the cg and throw recommendations in this manual were based upon limited test flying. Please check with the manufacturer for current information before flying your su-27 for the first time. For the first flight, set the cg at approximately 8.5 inches aft of the wing/fuse junction at the...

Subsequent flights • once you are comfortable with rates, expo and cg with the gear down, pull up the gear and find settings for normal flight. • watch residual...
