  • Page 5: Using This Manual

    30% Extra 260 Assembly Manual Step 1. Open and inspect everything This section should be fairly self explanatory. In the large box you should have a fuselage with hatch., wing tube and dual stab tubes, the elevator/stab assemblies, the rudder, cowl, wheel pants, canopy, and a package with the landing gear, tail wheel bracket and miscellaneous nuts and bolts.
  • Page 6 Lightweight landing gear and wing tube. In the 30% EXTRA 260 we have tried to provide as much flexibility as possible with regard to engine choice. It is some- times difficult to be all things to all people.
  • Page 7 plane with a 60cc(4.0 lbs) on the front, and it had an insane amount of zip. With HiTec 5945’s on the elevators, pull-pull rudder, and the 4.0 lb. engine on the front, the CG came out right on the factory recommendation without any batteries inside. Simply place one battery right in front of the wing tube, and one right behind and your CG will be very close.
  • Page 8 Now, let’s calculate the proper engine box length for your setup. Cowl length (minus) engine length = engine box length EXAMPLE: CL = 11 3/4” EL = 5 15/16” 11.75 - 5.94 engine box = 5.81 now let’s add ¼” so our prop will _ .25 have a little clearance from the cowl 6.06...
  • Page 9 Next mark your firewall with center lines. Label the firewall “Top” and “front“ with a pencil. Now measure & mark the last line as shown. The ¼” off- set is to counteract t h e r i g h t thrust.
  • Page 10 vent the proper fit of the triangular stock in the next step. After your wipe away the excess, a little rubbing alcohol on a paper towel will finish the job nicely. After you glue the firewall to the engine box sides, reinforce it with 1/2”...
  • Page 11 due will keep spilled glue from sticking to the ultracote covering. Then wipe off any excess oil from the surface. Glue the hinges into the holes securely using the glue you prefer. I have had good success with Pro-bond polyurethane (not the pro- bond yellow furniture glue) because when drying it foams up slightly and fills the gaps between the hinge and the mounting hole.
  • Page 12 Mounting the Hatch & Canopy The hatch mounts to the fuselage by two tabs on each side that are attached at the rear of the hatch. They are already built into the hatch and should have 6-32 blind nuts mounted in them. Set the hatch in place and check to see that the 6-32 bolts (supplied) thread easily into...
  • Page 13: Install The Control Horns

    Install horizontal stabilizer Use a sharp hobby knife to carefully trim the covering around holes in the fuse for the stab tube and the bolt holes on each side. Slide t h e a l u m i n u m tube(supplied) through the fuse, and slide the stabi- lizers onto the tubes from each side.
  • Page 14 Find the open servo bay on the left and right side of the fuselage in the tail. Remove covering. Attach a servo extension to the servo cord long enough to reach the receiver, and tie this servo connector to- gether with dental floss or whatever you prefer.
  • Page 15 Mount the throttle servo in the floor of the engine box. If you wish to use a servo to control your choke, you can mount it similarly. Use 2 pieces of 1/16” ply as doublers for the screws to have some meat on both ser- vos.
  • Page 16: Main Landing Gear Installation

    Main Landing Gear Installation Using the four 8-32 X 1” long bolts provided, and four 8-32 locknuts pro- vided. Mount the landing gear to the main gear plate as shown in the pic- ture. Tail Wheel Installation Use a 2.5 mm or 3/32” drill bit to drill 3 mounting holes.
  • Page 17 Use three, 3x4mm self-tapping screws to secure the tail wheel bracket to the holes drilled in the last step. Using two 8-32x3/4” allen bolts, run them through the gear and through the holes in the pant. Take a small square piece of plywood and glue it to the inside of the pant.
  • Page 18 Trim the cut-out in the center of the rudder servo tray to fit your rudder servo. Glue the stiffeners to the bottom of the rudder servo tray. The tray will fit approximately in this position. You may want to delay this process until you have everything installed &...
  • Page 19 Run the pull-pull wires down the fuselage, and make sure the ca- bles are not rubbing on anything. Attach the large aluminum servo arm securely to an existing servo wheel and attach cables with hardware provided. The installation of the tank (supplied) and fuel lines is very straightforward.
  • Page 20: Wing Mounting

    Once the cowl is ready to mount, slide it onto the fuselage and attach using 6-32 bolts and washers pro- vided. Two screws go through the firewall into the cowl ring – two go through the ring into the firewall. Blind-nuts are already installed to re- ceive them.
