Today was all about the wing locking mechanism and wing attachment. This took quite some time! This is one thing i will improve in my next builds...no scratch building at this in the future.

The locking mechanism is really simple. Some guidance holes in the front part and a canopy lock at the back. Both plates are 4mm light ply. The holes are reinforced by brass tubes which greatly helps against wear.
The wing is detachable and then attachable in seconds and thats exactly what i wanted.
Some reinforcements are missing right now. I just wanted to get done for today

Thats all i can say...no big changes to see but a huge leap for final construction. All the big structural steps are done now.

Thanks in advance
Your English is fine (much better than my German ) and your build is looking very nice.

Since you asked for suggestions, I will offer two for future builds.
1: Rather than use those long, very flexible (and therefore unreliable) push rods for your tail surfaces, try mounting your servos inboard on the surfaces themselves or within the empanage body. This will allow you to use conventional 2mm wire push rods making your control much more positive and reducing the strain on your servos
2: Nacelles can be made simply by using a former. I use styrofoam drink cups available at many fast food chains. These create a smooth thrust tube and provide that difficult taper. They can be easily laminated with depron, and then sanded to shape.
Hope you find these suggestions helpful in future. Keep up the great work, I'm subbed and anxious to see this project fly.

Cheers
Joe

Hi Joe,

thank you very much for your suggestions and that you took the time to write them down here
Great to hear that my written english is ok! German is quite similar though ( history lesson attention English is a germanic language and is derived from certain german dialects- little history lesson: off)
I am definitely as anxious as you are Can´t wait to give full throttle after takeoff clearance

I just like to keep things separate, so here is the status update:

Today i made the center wing box and fuselage transition fairings. For that i took my plan, cut out the wing box and transfered the lines to the fuselage so that i had a rough orientation.
The fairings are made from 3mm Depron with 6mm Depron supporting spars.

The section with the landing gear bays is made from styrodur (roofmate) to add some stability to the rear wing mount.

The outline of the fairings should be scale, but i had to create a bubble shape at the wheel wells to allow double-wheels to fit.

A very good thing is that the vinyl arrived today! 4m white, 4m light grey, 3m silver....all glossy. So finishing can start this weekend or so.

Alright then. Not much change right now, but there are some things i did.

I assembled the pneumatic system to find out that the handpump i bought doesn´t deliver the pressure needed. I then got an electric hand compressor. At ca. 7 bar (approx. 101PSI) the tank cap flew away!!! Fortunately i wasnt injured!
So after finding the cap i noticed that it was completely broken...so i had to get a new tank in the same size or slightly larger for 0.75mm inner diameter pressure line....
For now i ordered the small 100cc tank from HK - and i just hope that i can manage to get my pressure line connected...

Then today i finished the nose and nose gear assembly. I used a carbonite gear 9g servo and 0.5mm perlon cords for steering.
I also cut out the ailerons and made new - and more rigid - ones. After i sanded the leading edge in shape the wing is ready for covering with vinyl. This will happen soon!

Now take a look at the new tyres

Hallo Andre,

wonderful build. Thx for the plan !Allow me one question,
isn't the frontgear retracting in the wrong direction ?

Hallo Rudi,

its nice that you like it And yes, the nosegear is retracting in the wrong direction. I have done that because of the length of the leg. The engines are close to the ground so i need long legs. The available space in the bow is very small and the steering mechanism is pull/pull, so to keep it simple i switched direction....

But since i am having trouble with my air retracts i already ordered electric ones. Then i can change it again to the scale version.
