1 General Building Notes
This model features mostly conventional construction methods and so should
present few problems to the experienced builder. This is not a beginner's model.
If you have limited building and/or flying experience, it is strongly recommended
that you start with a more appropriate model and work up to the Do 335.
1.1
Getting Help
If you need help or advice, please don't hesitate to contact us. Email and phone
are listed on the title page.
1.2
Laser Cut Parts
Most of the laser cut parts can be gently broken free of the sheet. Be careful,
though, some parts will come out cleaner if you cut through the little “breaks”
with a hobby knife before removing the part from the sheet. This is particularly
true of the lightening holes in the ribs and the more fragile balsa parts. For best
results, place the parts sheet on a cutting board and cut through all the “breaks”
in the laser cuts before removing the parts from their sheets.
1.3
Adhesives
CA glue is fine for balsa to balsa and balsa to lite ply. For high stress areas and
ply to ply joints, epoxy is recommended unless otherwise specified.
1.4
Electronics
If this is your first high-powered electric model, proceed with extreme caution
when handling, soldering and connecting batteries and speed controllers. A
short or reversed connection can
FRY
some very delicate and expensive
equipment! When soldering connectors onto LiPo batteries, work with one wire
at a time and make sure the other is well insulated. Shorting these batteries will
cause damage, and it is very easy to do if you work with both wires at the same
time. Make absolutely sure you have the connections right before applying
battery power to the speed controller.

1.5.1
Building Options
Two Seater and B-series
Drawings are shown on the plans for the two-seat version (A-12, etc) of the Do
335. No parts are provided however. The Do 335 B-series canopy and cannon
are also shown on the plans.

1.5.2
Retracts
The Spring Air 100 series retracts (or similar) are recommended for this model.
1.6
Glow Power
If you choose glow power, you will need a .40-.60 sized engine for the nose, and
a .25-.40 sized engine for the tail.
1.7
Motor/Speed Controller Choices
The prototype used xxx motors and xxx controllers.
1.8
Building Guide Illustrations & Photos
Some of the photos may not be all that clear in the printed building guide. A
downloadable PDF version of the guide is available on the Yahoo group (see
references at the end of this document). The photos are clearer (and in color!)
when viewed on a computer.
