I want to show you a variant of such shnyaga -Mako Sea Plane, which the author offers in my article, this model can take off from grass, snow, and water surface!
A few words about the materials.
Ceiling - 4 mm
Heater "Penopleks"
Universal adhesive, moisture resistant - "Titanium"
Scotch is different.
The author suggests starting the construction by cutting out the inner walls of the floats with keels. The rudder is immediately cut off from the workpiece. For strength, a strip cut off from a wooden ruler is glued between two layers of the ceiling.
There should be two such blanks.
I want to remind you, do not forget to cut the trailing edges of the LV blanks at an angle of 45 degrees.
Further, the author cuts out the bearing part of the model, the wing plane, which is also strengthened with wooden rulers glued between two layers of the ceiling.
After bonding, the ailerons are cut off.
This is how pH is hung on tape.
Glue the inner sides of the floats on the lower surface of the wing.
Often check with a square the installation of parts at right angles.
We place partitions inside the floats to create strength.
We mount the outer sides of the floats.
Now we sew the bottom of the floats.
Both floats must be the same.
In the manufacture of the bearing part of the PB, a wooden ruler is glued between two layers of the ceiling.
RV is hung on tape. Do not forget to make a cut at an angle of 45 degrees on the front, lower edge of the workpiece RV.
All this construction is glued between the keels of the model.
On top of the wing we glue the blanks of the side walls of the fuselage.
Mount the lower fuselage skin.
We also mount the details of the upper fuselage skin.
The motor mount is reinforced with a piece of insulation. We glue a piece of a wooden ruler to mount the motor.
To access electronics and install the battery make the cover.
The turn came to cover the model with colored tape. Here you can give vent to your imagination.
The bottom surface of the floats can be covered with adhesive plumbing tape.
Now you can install the electronics.
Mount the servos.
The places of entry and exit of wires from servos are sealed with glue.
Traction to the elevator and rudders are passed through the Bowden.
Install the motor.
For fastening the battery, glue a piece of Velcro.
To better cool the electronics, an air intake is made on the upper plane of the nose of the fuselage.
Here is the finished model. You can try it.
Model flight video.
Dimensions of the model.
Span - 820 mm
Length - 890 mm
Flight weight - about 550-600 g
Electronics.
Motor - 2212 2200 kv.
The regulator is 30A.
Servos - any 9g.
Screw - 8x3.8
The battery is 1500mAh 3S 35C and 2200mah 3S 40C. In conclusion, I want to remind you that in this model the determination of the CT model is very important. With a model length of 890 mm, the center of gravity of the model, according to my calculations, will be at a distance of 32.9 cm from the front tip of the float.
Successful flights to you.
