Undercarriage
Steps 45 to 47
•
Build the undercarriage supports from the 8 basswood pieces. Note there are
4 similar pieces with longer slots; make sure you don’t use these. The 8 are
close to each other in the basswood sheet.
•
Glue 2 together at a time ensuring they are exactly lined up, making 4 blocks.
•
Fit the blocks as shown to the lower front fuselage in the notches in the
formers. Note they are angled outwards.
If you intend to cover the model it is far easier to do it at this point. The
rest of the parts can be added later. If you are new to tissue covering,
you can find help at the following link:

Steps 48 to 51
•
Select the undercarriage legs from the basswood sheet and join as shown
with micro screws.
•
Using a length of the wide strip wood, add a piece as shown to the outside of
each strut.
•
Attach the completed struts to the mounting points on the fuselage with
micro screws.
•
Fit a length of carbon rod through the holes in the undercarriage legs
Steps 52 to 59
•
Make up the wheels from the parts shown.
•
Glue together the 3 balsa parts of each wheel with the smallest circle in the
middle, and the 2 basswood pieces between the larger circles.
•
Fit the tyres over the wheels.
•
Fit the wheels to the ends of the carbon rod axle and put a small piece of
heat shrink tubing outside the wheels and shrink to hold the wheels in place.
Apply a drop of cyano glue to the end of the tube to secure in place, making
sure none gets onto the wheels
•
Add the basswood tail skid to the rear fuselage.
