17.Locate the mechanic shims in the photo.
18.Glue one shim without the square holes on top of one shim with the square holes. Do 2 sets.Attach the stacked shims to both the front and rear mounting points on the mechanic as in the photo.After the shims are screwed in securely, add 2 more layers of shims to the rear of the mechanic.The front of the mechanic only requires 2 shims.
19.Locate the former F2 and tack glue it with a few drops of CA glue onto formers F7 lining up the front edge with former F5.Do a dry fitting first.
20.Photo shows the location of former F2
21.Locate the rear section of the floor board in the photo.
22.Using photo as reference, first dry fit the rear section floor board onto the frame work, butt it up against the rear edge of former F2, once all is square, tack glue it into place with a few drops of CA.
23.The photo shows the location of the mainshaft, which determines the location of the mechanic. Insert the mechanic with the shims attached into the fuselage and adjust it until it sits centered and corresponds to the distance in the photo.Once all is correct, use the 4 mechanic shims' mounting holes as template and transfer the hole location onto the floor boards.Take the mechanics out again and remove the floor boards.Drill mounting holes in the floor board. Glue the 4 mounting screws for the mechanics from the bottom up. Finally glue the floor boards back onto the formers F7 frame work and reinstall and secure the mechanics using lock nuts on the top.
24.Glue the tail boom fuselage half to the front main fusleage.
25.Locate all the wood formers and pulley wheels and bearings for the tail elbow gear box. Assmeble them using the photo as a guide. The tension wheel in the photo needs to be installed now.
26.Locate the tension wheel, pulley wheel, bearings, shafts and shims.Insert the shafts through both the pulley wheel and tension wheels and centre them.
27.Close up of the cross members.Do dry fitting of all the formers before proceeding on to gluing.Note that the shorter cross member fits in at the bottom of the assembly.Note that the white tension wheel has to be installed now before the 2 sides of the elbow gear box are assembled.
28.Now glue the front cross members. Again 29.Glue the rear wood flange to the sides of note the shorter cross member sits at the top the elbow assembly as in the photo. The of the elbow assembly this time. flange is guled to the rear cross members' and will make the flange sit at a slight angle.
30.Close up of the inside flange to cross members' glue joints.
31.Slide the supplied tail tube into the assembly but do not glue at this time.
32.Locate the pulley wheel nsuppoert bracket 33.Use 2 shims per side of the pulley wheel parts as in the photo. and insert into the bottom of the elbow assembly.
34.Dry fit the pulley wheel support brackets and mark for left and right hand. Glue the 2 bracket parts together but DO NOT GLUE to the elbow assembly. The brackets will be held in by screws.
35.Glue former A to the location in the tail boom as shown in the photo. Leave a gap of about 5-10 mm from the edge of the tail boom opening.
36.Locate the rudder servo wood mount in the photo.
37.Photo shows the location of the rudder servo mounting location.You can mount the rudder servo either on the left or right side as you wish.After dtermining the location of the rudder servo, you need to move on to the rudder push rod installation.
Rudder push Rod Installation 38.Slip the rudder push rod plastic outer sleeve from the rear forwards.The push rod outer sleeve should sit flat against the inside leading edge of the fin as in the photo. The outer sleeve should curve down and rest against the bottom of the inside of the tail boom. Avoid tight curves to ensure a smooth rudder push rod operation.Push in the elbow assembly and check for fit. If necessary,you can run the outer sleeve through the holes in the elbow assembly front cross members. Tack glue the outer sleeve in place for now.Photo shows a typical installation in a similar case.
39.Run the outer sleeve all the way up to and pass the rudder servo for now. Tack glue the rudder servo end in one place only. Now slip in the metal push rod and check for smooth operation and no binding. Once the operation is smooth, run thin CA along the length of the outer sleeve so it will glue onto the inside of the fuselage. The push rod sleev installation is now complete.
Elbow Assembly Installation
40.Photo showns the approxiamte location of where the tail boom sits. It needs to protrude about 5 - 10 mm from the rear face of former A. Mark the tail boom and cut to length. IMPORTANT The tail boom needs to sit in a position above the rear horizontal stabilizer opening.
41.Reinsert the elbow assembly and line it up with the tail boom.Pull out the belt from the tail boom and thread it through the pulley wheel and install the puleey wheel into the slot and secure it with the 2 bottom brackets like innthe photo.
42.Pull the belt through the tail tube on the elbow assembly. Assemble and hook the belt to the tail gear box pulley wheel.Pull the tail gear box and tail tube assembly to achieve a tighe belt tension. Once the desired tension is reached, tack glue the tail tube to the elbow wood assembly with CA.
43.Now adjust the vertical poaition of the elbow assembly in relation to the tail tube. When correctly adjusted, the belt should not rub against any surface.Tack glue the elbow assembly in place. You can now use epoxy to glue the elbow assembly onto the inside of the fuselage.Use generous amount of epoxy for gluing.
44.After the elbow assembly is glued, recheck the tension of the belt again, if needed, break off the tail tube from the tack glued points and readjust. Once the belt tension is tight you can use epoxy and glue the tail tube to the elbow assembly wood frame.Please remember to maintain the tension of the belt while the epoxy is drying.
45.Locate the boom holder part in the photo.
46.The photo demonstrates how to use the boom holder part.Slip it onto the boom and glue it to both the boom and former A.
48.You can choose to further reinforce the elbow assembly by gluing former B at an 47.Photo shows the boom holder when glued angle to both the elbow assembly base and correctly. the sides of the fuselage. Use photo as reference for this.
Tail Cover and Stabilizer Installation
49.If you choose to install the rear metal skid, the photo shows how to glue it to the inside of the tail cover.
51.Fit the tail cover onto the tail fin and tape in place. Drill 1.0 mm mounting holes through both the tail cover and the tail fin lip. Fix with the supplied 1.5 mm screws.
50.The skid viewed from the outside.
52.Fixing screws in place.
53.Now insert the horizontal stabilizer into the hole in the tail boom and slide it out the other side. Center the stabilizer and once centered, glue into place.
Top Cover Panels Assembly 54.We recommend using magnets to hold the top covers in place. Strong magnets will prevent the covers from detaching in flight. The photo shows one possible method of attachment for the rear section of the top cover.When using magnets you will need to glue another magnet at the corresponding location on the fuselage side.NOTE the polarity when you glue the magnets.To install the rear section of the top cover, you will first need to detach the rotor head, slip the cover on and reattach the rotor head.
55.Underside of the front section of the top cover.
56.The attached rear section of the top cover.
57.The attached front section of the top cover.
58.With both rear and front sections in place, you can glue on the air filter section.Before gluing place the air filter section on top of the rear section of the top cover noting that the location will not bind the operation of the swash plate when pulling pitch. Once the location has been determined glue the air filter to the rear section of the top cover ONLY.
Windows and Doors Assembly
59.Locate the wind shield and lower front windows as in the photo.
60.Dry fit the wind shield onto the window opening as in the photo.Note that the wind shield is handed and will only fit correctly one way. Once the fit is satisfactory, glue in using either canopy glue or clear silicone glue.
61.Dry fit the lower front windows onto the openings. Note the windows are handed and will only fit on one way. Once satisfied with the fit glue in using canopy glue or clear silicone.
62.Locate the supplied clear acetate sheet and lay it out on a flat surface.Do not remove the protective sheeting yet.
63.Lay the front and side doors on top of the clear sheet and using the window openings as template, transfer the outline of the window openings onto the clear sheet. Once the window marks are done, cut out the windows, BE SURE TO LEAVE AT LEAST A 5 MM GLUING LIP AROUND THE WINDOW MARK.Try to be economical here as the extra material saved can be use as spare in future.Glue the windows in from behind using canopy glue or clear silicone.Remove the protective coating before gluing.
64.Place the unused clear acetate sheet onto of the top window opening and mark around it leaving a lip of approximately 5 mm.Cut the sheet following the line and glue the top window in from the underside using canopy glue or clear silicone.Remove the protective coating before gluing.
Doors Assembly 65.Fit the front doors onto the fuselage side. Some sanding might be required on the door for a perfect fit.Locate the supplied door hinges and place them onto the door and fuselage, adjust the location of the hinges according to your liking and then tape into place.Use the hinge's fixing holes as template, drill 1 mm holes on both the door and fuselage. Screw in the fixing screws and secure the screws with a drop of CA on the inside.You choose which method to secure the door. We recommend strong magnets in the same format as the fuselage top cover.
66.Another view of the door hinges' location.Now do the other side.
67.Again you can choose your own method of securing the side doors, we used the magnet option mentioned before.This allows quick access to change batteries and minor maintainence.
