@ Mrotar > Thanks a lot

Now I continue with the fuse.
At first I hat to prepare the vertical decks. These parts are very important. They carry the lower wing and the landing gear.
The milling machine from my buddy wasn`t big enuogh to make it as once so he did it in two parts.

I glued them together and they are covered with carbon fiber.

As next parts I cutted the gear bridges from carbon fiber covered plywood.


Now I need two bearing blocks, they fix the screw spindles. The parts are cutting fromn "Novatex", light, solide and easy to work with.

Till this time I was on the bright side of life, in my minds the landing gear was finished, all my fears abiut it were in a long, long past.
I builded a gear box, assembled it.



built into the fuse, it looks great.




But then, the first test > se your self > a real desaster:
The drive was to weack, the transmission ratio was complete wrong, the current consumption to high, and I was destroyed.
The next gear attempt I started with a worm gear.

It also failed.
In our modelling club the guys helped methink and we found a solution.
Now I use strog servos as drive, 40 kg power. The electronic is removed. The first attempt with tooth belt looked promising,



the final solution now ist a spur gear.







I marked my success on my studio door


And here it is
