Thank you for purchasing the Mountain Models Tom-E-Boy™ 150. The Tom-E-Boy™ 150 is a small model
designed with influence from the famous Vic Smeed Tomboy, to bring back that nostalgic feeling of
yesteryear, in a small field electric packag e. The 30 inch Tom-E-Boy™ 150 is super easy to build and easy
enough for a beginner to learn how to fly with some friendly help.

The Tom-E-Boy™ 150 was designed using a state of the art 3D CAD package, to allow for exceptional
interlocking parts design and fit. 3D design also allows us to provide clearer as sembly image s, without
having to use photos.

The Tom-E-Boy™ 150 is built from self-jigging interlocking laser cut balsa and plywood parts. It's like a 3D jigsaw
puzzle with instructions. Although not needed for building, full size plans are included for reference. If the
instructions are read before hand and followed during the build, the Tom-E-Boy™ 150 can be built up and ready to
fly in only 2 to 4 evenings.

We think you’ll like the Tom-E-Boy™ 150 and look forward to any feedback you might have.

Thank you,
Brian Eberwein

General Building Tips

 READ THE INSTRUCTIONS all the way through and study the plans BEFORE starting any

work on the model.

 PRE-SANDING: BEFORE removing any parts from the balsa sheets, use a sanding block

with 320 grit sandpaper and lightly sand the back of the balsa sheets. Our balsa suppliers
have been sending us wood that is over sized, so sanding the backs of the balsa sheets
reduces the thickness just slightly and removes any charring from the laser cutting process.

 Tape the plans to your nice clean work surface and cover it with wax paper or plastic wrap.

You want to keep your work surface clean and not glue the parts to the plans, right?

 Balsa is a lightweight and fragile wood, so you do need to be careful with it; however, you

will also need to use a little bit of force to make everything fit properly, so don’t be too
timid.

 Do not remove any pieces from the balsa sheets until they’re ready to be used. That way,

parts won’t get mixed up or disappear.

 Do NOT glue anything until told to do so.
 Join all of your pieces using thin CA (Cyanoacrylate) glue, unless we tell you otherwise. In

general, only a small amount of CA is necessary to glue parts together.

 Don’t over force your pieces together. If they aren’t fitting together properly, make sure you

have the right pieces and that they are oriented correctly. If needed, you can lightly sand
the part to fit after making sure it is the correct part and oriented correctly. On balsa “tabs”,
you can “pinch” the wood with your fingers to get them to fit in slots. (The tabs might be
tighter some times, due to tolerances in wood thickness)

 If you want to remove the charred edges caused by the laser cutting process, lightly

dampen a cloth with bleach and gently rub the affected areas. Removing the char will not
increase the strength but will make it look better. It also keeps that dark edge from showing
under the lightweight coverings.
