Thank you for purchasing the Mountain Models Roland c.II Walfisch. The Roland C.II was one of the most advanced
aircraft when it first appeared in March 1916. It featured a sleek, streamlined wooden fuselage that gave rise to its
name of "Walfisch". Another novel innovation was the lack of cabane struts, instead the upper wing sat on top of
the fuselage giving an uninterrupted view of the sky above.
The Mountain Models cartoon scale version of the Roland C.II Walfisch 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
assembly images, without having to use photos.
The Mountain Models Roland C.II Walfisch is designed to use the ParkZone and E-Flite Ultra Micro DSM2
electronics.
The Roland C.II Walfisch 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 beforehand and followed during the build, the Roland C.II Walfisch can be built up and ready
to fly in only a few evenings.
We think you’ll like the Roland c.II Walfisch 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.
•While not absolutely required, we suggest that you use a lightweight clear sealer, VERY
SPARINGLY, to protect the wood in humid climates. You only need a fine mist, not a direct
spray to seal the wood enough to protect it.
