Heinkel He 100D (oz13915)

About this Plan

Heinkel He 100D. Radio control scale model WWII fighter, for RC combat. Wingspan 80 cm. Scale is 1/12.

Quote: "It's been a long time since I got a book about the Heinkel-Flugzeugbau company for my birthday. Since then I have flipped through the book and read it again and again. Again and again I got stuck on the record aircraft He 100V-8, with which an absolute world speed record was flown in 1939. The aircraft turned out to be a completely normal fighter plane, apart from the engine system. However, the machine could not assert itself against the slower Messerschmitt Bf 109, as this was much simpler and more robust and therefore better suited for field use. The machine did not go beyond a small series of machines for propaganda purposes and for plant security.

In aircombat competition, these differences between the former competitors are not particularly noticeable. Also, as far as I know, nobody had dealt with this guy in the aircombat scene before. So Neuland, exactly my thing.

Due to its small size and the high speed that can be achieved as a result, the machine is not for aircombat beginners or for beginners in model flying. Only those who have experience with small, fast, aileron-controlled models will have great fun with this machine.

Construction of the model: The He 100 has such small dimensions that it can certainly be built from 'leftovers'. My machine was practically made from the contents of my leftovers box. However, the weight is important when choosing the material: 'Light flies well' and that saying is paramount. Light weight, low wing loading machines are better suited to competition, and they are faster, more maneuverable and climb better.

Wings: These are constructed in the normal styro-balsa construction. The selected profile SD6060 is very well suited here, as it still works reliably even with a low surface depth. 1.5 mm balsa is used for planking. To increase the strength of the wing, it can also be planked with 1 mm balsa and then covered with 50 g/m2 glass fabric. You have to make sure that the washout of the ends of the wing is maintained, otherwise there could be nasty surprises in flight.

The ailerons only reach over the two wingtips. They are therefore quite short and do not have to be further stiffened. I could not detect any rudder flutter even at high speeds.

If the two outer surfaces and the wing base are planked, the front edges of the surfaces are sawn off according to the leading edge. I always use a pendulum saw, it's quick and clean. Now attach the leading edge and wing tip and sand everything cleanly and evenly. Now glue the block for the surface bolt in the middle of the base surface. To stiffen the bolting of the surface, attach glass fabric around the hole. Now attach the two outer surfaces to the base surface under 6' each. Then reinforce the surface joints with fabric and epoxy.

So now cut out the ailerons and box them up. If you take a leftover V-shaped trailing strip on the wing and on the back of the aileron, you don't even have to sand down the area of the hinge afterwards. The torsion linkage is made from 2 mm spring steel and a matching Bowden cable tube. Two balls can now be soldered to the ends for linkage. I use fabric hinges as hinges, which can be easily glued in at the end with superglue.

Fuselage: First cut the two fuselage halves out of flexible balsa (a 1 meter board is sufficient for both halves), then glue on the wing support. Attach the triangular strips in the same way. Then carefully saw out the fuselage frames. Glue the frame template to the wood with a glue stick and then saw out all the parts with the jigsaw.

In the second assembly step, glue frames 2 and 3 in place at the correct angle. Caution: Glue should only be on the flank of the frame leading from the spigot downwards. Then glue the other side of the fuselage to frames 2 and 3. Then glue motor frame 1 in place and close the end of the fuselage with frame 4 plus wing screws and frames 5 and 6. It is important to pay attention to the axis of symmetry. Now pull the fuselage sides moistened to the frame arches and glue them. Stiffen the front engine and tank area with the 8x8 mm balsa triangular strips..."
