Build Log

Cessna 152 - 2,7meter - gasoline engine 55CC


Greetings to all. I begin construction of Cessna 152 models and maybe 150, to be honest, I did not understand what their difference, and this was not an objective.
Model without claiming to be a copy of, as normal drawings I have not found, its development is based on a variety of schematic drawings and pictures from the network.
The idea of building this model was born back in 2014, the model was difficult for me, so that the drawings and tooling took about 2 years, frequent deadlocks and finding technical solutions greatly hindered the process.
But like everything was decided and turned, so proceed to the assembly



The terms of reference of this model include:

Flying flags.
Resetting the radio-controlled parachutist.
Pyrotechnic smoke bombs on the wings.
Glider tow. Grunau Baby 2
Takeoff / landing on water, the hydro option on floats.
I tried as much as possible to prepare for the construction site, have prepared materials.
Birch plywood 3mm. and balsa plate 3mm. cut with a laser.









Fairings chassis, fiberglass.













Engine hood, fiberglass.













Chassis 100 mm diameter.



Landing gear, duralumin D16 4mm.



Balsa for skin 100x100x1,5mm. 30 sheets.



Nut M4 50pcs.





Pine slats - stringers, spars, wing struts.



Pipe wing center section, aluminum 25mm diameter, 640mm length.



Tube center stabilizer, aluminum 14mm. diameter, length 290mm.





Glass float is not ready yet, so far only a fool, I prepare for the removal of the matrix. All exactly at the initial stage of assembly floats do not need, so I decided to start without them.

Selection of parts took a lot of time





The weight of the plywood parts.





The weight of the balsa parts.



At the moment I have about 4kg of all materials.
I assume that the empty airframe will weigh about 5kg.

This should be an interesting build that many of us will be watching. Good luck and keep the progress reports coming.

Thanks friends. The scale is 1/4 (approximately). Wingspan 2700 mm. take-off weight of 9 kg. (would like to)

Pre-gluing of structural members.

Mount the bomb Bay.



Frame number two. Attached the nose landing gear and the front floats.





Detail of fastening of a strut of the wing to the fuselage.



Sidewall moto boxes.



Detail of fixing rear strut of the floats to the fuselage.





Internal charge , the floors in the cabin.





The first frame moto boxes.



Upper Board, the ceiling in the cockpit.







The seventh frame of the bow.





The cockpit door. First thoughts were to make the opening, but then changed his mind and pasted. Wouldn't hinges, locks bother.







The first frame of the tail boom, the response to the bow, with nuts M4.



Charge of the servo of the rudder.



What sort of slipway, to build the tail boom.



The last frame of the tail boom with M4 nuts for fastening of the keel.

Very nice!

I am looking forward to seeing this come together as well as getting some inspiration.

I like the slots cut for the blind nuts.

Thanks Leroy, Yes I like precision.

In this detail the mechanism of uncoupling for the towing rail. For centering of work pieces together I tried to use toothpicks, it seems to happen.











The last frame of the forward fuselage, the response to the tail boom. For centering of the parts used screws M4.





This detail of mounting front landing gear.







The details of attachment of the strut to the wing. Also with nuts M4.





M4 nuts, the mounting of the engine hood.





Mounting parts main landing gear, M4 nuts.




The floor frames of the bow, this item will be attached the main landing gear or strut of the floats.

Very nice, clean work!!!!

I lived in Ukraine (Odessa) for 4 years, and St. Petersburg (Russia) for over one year and never found anyone into RC planes. Good to see the hobby alive over there!

I'm surprised, in St. Petersburg lot of RC modelers. In Odessa too.

All pre-gluing the parts completed. i can now begin to assemble.

As always, it all starts with the Moto boxes.











Before gluing collected on dry, as it turned out there is a certain sequence that cannot be broken.











The main time in the Assembly is spent waiting when the glue dries.

Continue assembling the bow.























The floors in the cabin.







The upper part of the fuselage practically hanging on four pillars, the cabin is glazed in a circle, to stiffen pillars holding the roof represent the boxes.
This is the inner part pillars boxes.























In this photo, embeds for attachment of the windshield.

Yes, Micah, the twin would look good here. But I have a EME 55. I will put that there.

Assembly of the bow continues.





Internal detail of the rear of the cab.






















The last frame of the bow, return to the tail boom.







The Foundation for the rear glass.










Here in this place will be the mechanism of uncoupling of a rail.

Excellent progress!

I lived in St. Petersburg in 1995-1996 and Odessa from 2000-2004. In Odessa, I knew one guy who was into control line flying, but no RC guys.

Perhaps in those years there were few modelers, are now many

I confess I didn't even think to glue this thing will have a few days, the previous model was going clearly faster.







The lower the floor the frame serves to brace the stringers.





Front power frame. Attached the front landing gear or the front floats.











Nuts "bomb Bay".









As planned, into the lower cavity of the fuselage "bomb hatch" should be attached box.
In the box there will be mechanisms for a particular function.
Reset parachutist, flags , etc., under each function will have its own box with the mechanism, box can be switch.
The mechanisms have not yet been invented, I decided to leave this for a snack.
