  • Page 5: Rudder Installation

    We have found this to be helpful with models intended for higher speed flight or models with unusually large hinge gaps. OMP aircraft utilize a very tight double beveled hinge line and do not normally require this step. Sealing the hinge gaps is therefore left as an option for the modeler.

    3. The hinge slots for the rudder are pre-cut in the rudder and fin. Locate the CA hinges and align them in the fin. Once aligned and centered in the fin glue in place with thin CA. LANDING GEAR ASSEMBLY: 1.
  • Page 7 2. Bolt the main gear to the bottom of the fuselage using the supplied bolts. Use a small drop of thread- lock to secure the bolts in place.
  • Page 8 3. Install the main wheel axles to the composite landing gear and tighten the nylon-insert lock nut. Note that the axle is a hex head bolt. The hex head part of the bolt is to the outside of the wheel. Use 1-2 nuts to space the wheel from the axle for wheel pant fit.
  • Page 9 4. Fit the wheel pant in place and install using the two supplied wood screws. Repeat the above steps for the other main gear. 5. Begin the tail wheel assembly by installing the shaft through the hole at the rear of the tail wheel bracket.
  • Page 10 6. Center the tail wheel bracket on the rear of the fuselage. Note that the steering arm attaches into the rudder and the steering arm shaft has to fit flush against the fin. Before attaching tail wheel assembly, make a 90 degree bend in the last 1” of the shaft. Make sure that you make the bend in the right direction! The bent part has to fit into the rudder to provide rudder steering on the ground.
  • Page 11 2. Now install the rudder to the fuselage. Slip the CA hinges into the precut slots and make sure the rudder is aligned correctly and glue the hinges with thin CA. Next, install your rudder servo into the precut locations in either the radio trey or fuselage side in the tail (See note above). You will need to locate the hole in the side of the fuselage and remove the covering.

    If you use the Hacker A50-14S or equivalent you will need about 3/16 spacers. If you use the Dualsky motor that OMP sells in the combo package, you will need to make 5/8” stand offs. Notice that the engine center line needs to be offset to the left to compensate for the right thrust built into the engine box.

  • Page 13: Cowling Installation

    COWLING INSTALLATION: 1. Locate the four screws that are put into the blind nuts that are installed in the fuselage. These four screws are the mounting device for the cowling. The holes that are in the cowl ring may need to be enlarged slightly to allow the heads of the screws to slide through them.
  • Page 14 minute epoxy. The slow drying time will give you the time to make the alignment measurements again and get the stab on straight. 2. Locate the elevator halves, elevator connecter piece and CA hinges. Starting with the elevator half that will be on the elevator servo side, locate the control horn opening and remove covering and glue in carbon fiber servo horn with CA.
  • Page 15 To perform properly without being too pitch sensitive, you must not go too aft on the CG. OMP recommends the initial CG setting of the leading edge of the wing tube. Once you have flown the plane several times, then move the battery back and forth to achieve the CG that best suits you flying style.
