Jet airliner Boeing 777

Hello.
I started this project on 2014.
Main characteristics
wingspan 3.1m
fuselage length 3.0m
scale is around 1:22
First model was EDF version with two Schuebeler DS-94DIA-HST. Foam wings, sheeted with balsa and fiberglass.
With two 12S LiPo's (5500 may) flying weight was 19.8kg flying time 5-6 min

On this model I was testing all parameters: airfoils, angles, fowler flaps and more other.

Second generation is Jet engines powered and full composite construction. I made moulds.

Landing gear and air retract are handmade also like a wheels

Few days ago was maiden flight of Jet version.


Dry weight 16.3kg
Two JetCat P-100 reduced to 80N of thrust each
Two 2.7L fuel tanks
Strong wind conditions flying time 8:30 min

More flights was better weather conditions


Next step is to change engines to for example KingTech K-85 and reduce dry weight to 15 kg.

PS Emirates Airlines version also for Jet engines

Hello.
And in Romania there is a person passionate about the construction of airplane scales.
He made a single Boeing 747-400 on a 1/20 scale.

It is very interesting project Sir, I think that person must to open new discussion about this 747.
It looks like stand model, not flying? So any way we need more information about it: engines, weight, thrust and many other.
Thanks

Hi.
747 is ready to make the first flight.
The builder is looking for a suitable ground to make the first flight.
I will talk to the builder to open a new discussion on the rc-network forum.
