Battery Charger:
The charger for the flight battery pack is one of the most critical pieces of equipment for flying electric powered airplanes. Having the
correct charger and using it properly can make the difference between an electric airplane that flies well and one that can’t even get
off the ground. Failure to select the appropriate charger, or using it improperly, will cause performance related problems and
unsatisfactory results. By far, the majority of performance related problems we see with electric powered models are almost always
traced directly to an improperly or incompletely charged flight battery pack.
To correctly charge the recommended battery packs you MUST have a charger that is capable of performing “peak detection” charging
of NiMH (Nickel Metal Hydride) batteries. We use the ASTRO FLIGHT 115D charger, a top-of-the-line AC/DC peak detection
charger. This unit is capable of fast-charging or slow-charging either Nicad or NiMH battery packs at selected rates and is very versatile
in its operation. Obviously other brands of chargers can also be used, as long as they have capabilities similar to the Astro Flight 115D
unit -- i.e. most importantly, “peak detection” charging of NiMH batteries. An old R/C car battery charger WILL NOT work!
Before Beginning Assembly
Take your time and follow the assembly instructions carefully. The foam parts of your Fokker D.VII can be dented easily so be
gentle. To help protect your model during assembly, cover your work bench with an old towel or a sheet of foam rubber. Use only the
glues specified or you will damage the parts. Specifically, DO NOT use C/A Glue on any of the foam parts or they will be damaged.

Assembly Starts Here:
1...Use a small piece of 220 grit sandpaper to remove any
burrs from the ends of the two 4mm x 3-11/16” Aluminum
Wing Tubes. Now use your hobby knife to slightly
bevel/sharpen the inside of one end of one tube as shown.
2...Prepare the fuselage halves for assembly by using the
sharpened end of the aluminum tube to open up the four
required wing dowel holes in the fuselage sides. Lay the
fuselage half on a firm surface and gently press the tube into
the hole with a twisting motion to finish cutting through the
fuselage sides. Next, use your hobby knife to open up the
pushrod exit holes in the rear of each fuselage half. Last,
lightly sand the mating surfaces of both fuselage halves to
remove any molding flash from the foam.
3...Carefully apply 30 minute epoxy to one of the fuselage
sides as shown. Since the epoxy is many times stronger than
the foam, you only need to use a small amount to bond the
fuselage sides together. By applying the epoxy in this manner
you will eliminate having a lot of epoxy squeezing out on the
outside of the model. We recommend using #32 rubber bands
to hold the fuselage sides together until the epoxy cures. Use
care to make sure that the fuselage is straight and not bent or
twisted. NOTE: You can also use low-tack drafting tape to
hold the fuselage sides together if preferred. However, use
caution because tape can pull the paint off the model if the
adhesive is too tacky. Use tape only on areas of the model that
will not be seen after it is completely assembled.
