The giant R/C models are impressive!
The giant R/C models atract a lot of the attention on the shows! They are built by the most experienced modellers and flown by very experienced pilots! You should carefuly judge your capabilities when considering building of this model.
If you're going to build your first giant R/C model think about several important issues firstly.
Do you have sufficient space in your workshop? Moving wings of 200x70 cm size each, or fuselage of 3 meters length, 90 cm high weghting close to 30 kgs is not an easy task. Do you have big enough door to get the model in and out of your workshop?
You'll need a space where you'll be able to assemble the model, ideally indoor. To do so you need a room with at least 5x4 meters space.
If you store your model in a garage, your car probably won't fit in any more.
You won't be able to lift the model or even just the fuselage by yourself. You probably can lift 30 kgs weight but lifting up 30 kgs fuselage by hand holding it by the joining tube in it's center of gravity is good for a well trained body builder not for most of the modellers.
Unless you've got a realy large SUV or real estate car you won't be able to load your model inside the car. Even if you disassemble the model to maximal possible extend, the risk that the model will be damaged during the transportation is bigger than that it will be crashed during flying. A trailer of 3x1.5 meters size is the reccommended way of transportation.
Last but definitely not least issue to incude in your consideration! Let consider the following cost:
DXF Plans €10 :-)
Ply Wood, Balsa, Fiber Glass €200
