Bolkow MHK 101 (oz14407)

About this Plan

Bolkow MHK 101. Radio control scale model.

Quote (google-translated from the German): "Description of the Bö 209 (MILK 101) model: The model is built to a scale of 1:5.5. This results in a wingspan of approx 1540 mm and an enormous fuselage width of 195 mm. In terms of weight, this model can cope with all ten-channel systems without the wing loading becoming critical. With today's lightweight prop rigs, there are no difficulties to begin with.

The structure of the model is very simple and requires no more construction time than with the usual multi-channel models. The fuselage has a box construction. The intestines are very easy to access after removing the canopy. You just have to be careful to secure the system from falling out. With the first model, I relied on the canopy, which I attached with two rubber bands and thus believed that the system was secure. However, when it rolled, the hood became independent and the system was thrown out of the model. That cost me the model and participation in the competition for prototypical models on 17/18 May in Munich.

The engine is installed inverted and thus disappears completely, which gives a better look to the model. One half of the front fuselage floor was designed as a cover, on which the tank is attached. This means it can be easily removed from the model if necessary. The rudder and tailplane are made from a 6 mm balsa board and can therefore be manufactured quickly and easily. The area consists of 3 parts. The construction presents no difficulties. First, the two wing ends are made and then finished with the center piece. Finally, cut the ailerons out of the wing. The tricycle landing gear also makes the model easier to take off and land.

The first model had a flying weight of 2900 kp and was equipped with a 10 cc Enya. As an RC system, I still used the homemade Tip system. The rudder, elevator and aileron as well as the engine throttle were controlled. When the grass was already a bit high, the MHK took off perfectly after about 60 m. Due to the low dihedral of the wing, you should fly with aileron, the rudder is very sluggish and can only be used for taxiing. The model has good-natured flight characteristics and a surprisingly good glide even though the fuselage is very wide.

And finally, once again: When securing the RC system, do not rely on rubber bands, these are too unsafe. Especially with this model, where the system is accessible from above, you have to pay special attention to this. I had to go through the bitter experience, I want you to be spared.

Technical data of the model: wingspan 1540 mm, fuselage length 1080 mm, flying weight depending on the RC system 2500 p to 3000 p. Engines from 5 to 10cc."
