------ MAIN FUSELAGE STRUCTURE / Before you Start ------
If you are an experienced builder all the detail may not be necessary, if so skip
ahead a couple pages.
Building the Main Fuselage structure for the proXy will be similar to that of the Crack
Beaver. There are a couple different ways to do this, method and sequence shown here will
ensure that the X cross section of the fuselage will come out nice and square with little
effort. Things that will be critical to the success of this step will be to make sure ahead of
time that all the slits for the spars are deep enough and clear of nubs so that the spars
will lay into the slits nice and flush.
IMPORTANT PART FOR SUCCESS OF THIS STEP TO TEST FIT ALL THE PARTS
TOGETHER FIRST AND UNDERSTAND THE SEQUENCE OF EVENTS BEFORE
GLUING.
------ THE PROCESS / words ------
Start by rounding up the two main fuselage pieces
Remove any scrap from the cut out areas
Locate the fuselage section that has the LONG slits and SHORT tabs as shown
Split the tabs in half at the "V" marks
Locate the landing gear struts. Note that they are keyed unique
Test fit that the nubs match up perfectly and that the slits for the spars align
Attach the two pieces with FoamTac, using the "tackup" method
Hold a little pressure for a minute or two against the joint while the glue sets up
Repeat for the other side
Locate the Ele/Rud that is keyed to fit the large one piece fuselage section
Glue the two together with the "tackup" method, make sure the slits align
Hold a little pressure for a minute or two against the joint while the glue sets up
Take one of the two smaller carbon spars and clean it with alcohol
Fit it into the slit of the Ele/Rud piece that was just attached, make sure it is flush
Constrain it flat and then CA in place
Take the other smaller spar and the loose piece of the Ele/Rud
Clean, test fit, constrain and CA glue the two together
Get two of the larger spars and the one piece fuselage side
Clean the spars with alcohol and test fit, make sure that the spar is all the way to the top of the slit and flush
Also check that the remaining part of the spars at the end of the strut will be approximately the right length to engage the axle hubs
Do not glue the hubs on yet, they will get attached in a later step
Constrain, check for flush and CA
Take top half of fuselage and the remaining two larger carbon spars
Test fit them into the slits, again make sure that they go all the way to the upper end of the slit
Make sure they are flush, the constrain it all flat and apply CA
Test fit the last remaining smaller spar into the slit in the Ele/Rud
Constrain, check for flush and CA
