Easy way to get the screws through the
tires.
Ever get frustrated trying to get those pesky
little machine screws through the hard rubber tires? Here is a great way to get
all three tires ready in minutes. You'll need a large "T"pin. A way of heating
it up. I use my small butane torch. And a pair of needle nose pliers to hold
the pin with. Heat the pin up and push it through the aluminum hub, tire and
out the other side. It will go through like butter. Reheat the pin for every
hole. The machine screw will push through easily and be perfectly on line with
the opposing hole. You'll have all 3 wheels done in 10 minutes. Try it. It
works great.
Thanks to Bob Beaudette for this handy
tip.

Wing Sheeting Notes
Balsa is a product of nature and therefore it
naturally varies in grain type and hardness. The wing, stab and fin skins are
pre-joined and laser cut to fit the structures after a selection process is
performed at the BVM factory. The skins are of good quality but of course,
cannot be perfectly uniform (natures way), so here are some tips to help you
best apply the skins.
Choose 2 wing & stab skins that are the hardest (heaviest) of
the 4 provided. Designate them to be used on the top of the surface. This will
provide the sub surface for the best finish after the resin, cloth, and paint
are applied. The tougher skins on the top will also provide the maximum
resistance to positive "G" loads when the top skins are in compression.
Check both sides
of the skins for any unsanded saw marks. If any are visible, designate this
side to face inward to the structure. If the skins are a bit too hard to
conform to the curvature of the wing toward the L.E. the old technique of
applying a 50/50 mix of amonia and water to the outside surface really
facilitates the bending process. Apply with a fine spray or wipe on with a
dampened sponge.
We check the skins for a continuous glue joint but you may check
them as well. If a void exists between the 3" or 4" panels, apply thin CA to a
razorblade and then to the skin joint. Block sand this area on a smooth surface
with #320 paper.
Federal Standard Color Infomation
For those of you that want to paint your BVM
jet to match the real one's, you'll need to contact the Federal Support
Services Bureau to receive the correct color chips. They offer individual color
chips or a complete book of color chips. You can contact them at the following
address and phone number.

Z bend control linkages
Some of our kits show "Z" bends as the method
of linking a 1/16"
wire control rod to a servo arm or control horn.
This is a simple and effective system if you
have a good set of Z bend pliers. We have discovered that these tools vary in
quality and precision and therefore produce different results.
Jets require "slop free"
linkages, so if your Z bend pliers do not produce the proper result, do not use
this method of linkage. Rather, employ the use of solder clevises. We use the
Dubro brand with the Stay-Brite silver solder BVM #5786.
Keep all control linkages
as straight as possible, don't wallow out a hole in the servo arm for the sake
of convenience, and please don't fly your jet until all of these very important
items (control linkages) are accomplished correctly. Control surface flutter
can cause a crash. BVM instructions are very detailed in this area.
