IMPORTANT: PRIOR TO ANY ASSEMBLY
Please Note: after removing kit from shipping box, lay each piece flat on a
hard surface, this will allow the airframe to straighten out if lightly bent
from shipping. Do not worry since EPP is very pliable and can be bent back
if out of shape.

the build
CONSTRUCTION METHODS:
Building surface should be at least 2ft x 4ft and flat. Weights or some small heavy objects will be handy for holding things in place
during the time glue is setting.
Welders or FoamTac glue is used for FOAM TO FOAM joints. Thin and Medium CA can be used on the PLASTIC TO FOAM and
CARBON TO FOAM joints. When using the Welders or FoamTac glue for a butt joint, apply a thin film to each surface, allow to
sit breifly per mfg instructions, then assemble. Note that this method will create a nearly instant bond, so locate carefully when
bringing the two pieces together. If alignment is necessary or a slip joint, do not allow the glue to tack up, simple apply and join
immediately, you will have several minutes to locate the two parts before the glue sets up. In most cases the parts being glued can be
handled with care in 30 minutes, full cure is approx 24 hours.
¨Locate all the electronics that
will be used on this model
¨Create a model on your
transmitter
¨Following your radio mfg.
instructions, bind your radio to
the power combo components
¨Calibrate the ESC.
¨Confirm all components work
properly.

------ 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

----- THE PROCESS / words (con’t) -----
The next several steps will all be done WITHOUT GLUE it is for test fitting only and to
understand how the assembly will go together, study the pictures and make sure everything
fits together nicely
Take the top half of the fuselage with the spars sticking out and feed those spar ends thru the cut outs in the fuselage
Get it pretty close to the tabs, then focus your attention the the rear Ele/Rud spar and feed it thru its associated hole
Fully engage all the tabs and slots
Make sure that the bevels on the top of the fuselage are LEVEL, if they are not, you have assembled the pieces incorrectly
Grab the lower fuselage half and align the tabs at a slight angle to the slots in the fuselage
Engage the tabs into the slots at the same time as guiding the carbon spars into their respective slits
Push everything together, making sure that it all fits nice, flush and square
If any parts are not flush, fully engaged or not square, make the necessary adjustment to get everything fitting properly
This completes the TEST FIT WITH NO GLUE, keep in mind how it all went together and
disassembly all the pieces
Start the reassembly with the main fuselage piece and the top half of the other side of the fuselage
Apply FoamTac to the larger piece in all the areas where the two items will contact each other including the tab and slot
areas
Keep glue AWAY from the area where the spars cross thru
Fit the upper fuselage half and the strut spars thru the holes in the large fuselage piece like was done in the test fit up
Make sure all the foam tabs and slots are fulling engaged and that the strut spars and Ele/Rud spar are in their slits and
flush
Make sure the two upper fuselage member are nice and square with each other
Apply a little pressure to the assembly for a couple minutes to allow the FoamTac to make a good bond
Next the lower fuselage half will be attached, apply FoamTac to all the mating FOAM surfaces
DO NOT PUT GLUE THE SPARS AT THIS TIME
Move the two pieces into position as was done with the fit up
Make sure the foam tabs and slots are fully engaged
Double check that the spars are (dry fit) flush with the surface of their slits
Make sure all the fuselage pieces are 90 degrees to each other along the entire length
Hold a little pressure on the two pieces for a minute or two so that the FoamTac can make a good bond
NOW the spars will be secured with CA to their slits
Make sure that all the fuselage components are still square and that the spars are flush in the slits
Apply thin CA to all the spars and hit with kicker
This completes the Main Fuselage Structure
