Gents,
A little update.

I think some of you already do understand my way of building and flying model airplanes.

Most of the good thinks are thrown away, nearly forgotten and problem full things did come back.
Think about the threaded hangings and what I did write in the thread of Ckuck about his 6 volt battery pack.

The first proportionals did not have strong servo’s! We could read about that, the way Ed was thinking about the dimensions of the ailerons. Of course they did use 1 servo so eliminate at least the aerodynamic forces.
Now we use (not me) for every barndoor one or more digital servo’s. High torque, 6 Volt extra precise positioning, digital .
This again does ask for better battery’s and chargers.

The old servo’s did use 2,4 V (rest 2 V after the power transistor) for one direction to move, now people want us do believe we need 6 V! (Not talking about safety George, a reason to use 5 cells)
When it is all in you hobby room you are not finished yet , you need CF materials and titanium to bring all these mechanical energy to that barndoors, so…….. gluing that all together is your next problem. Because your fast and powerfull servo’s nearly shake off the pushrods and rudders. Read the stories.

After a short time you think, hé, where is all my money, and you want to show it your buddies. Make all that furniture on the outside of the plane. So let me predict, your next problem will be.

One collision with that fanatic Oystercatcher or other object in the air, end of the show!

To be a counterpart in that way of thinking I am going the other way. Back to the future.

Nothing visible on that very strong outside of the plane of the linkages. Reduce the energy to the rudders to a normal functional proportion so nothing can happen with the mechanical layout.
To protect the planes and feathers, spruce TE (2 or 3 mm thick) on every plane and 1 mm plywood in the LE of every aileron, elevator and rudder

A next environmental friendly step is to reduce the capital investment I refuse to buy me a massive block of balsa for the top of the fuse like Ed did.
A massive block, make it hollow and throw away 90 %, that’s not Dutch, that’s destroying of (nature) capital.
I tryto didgeridoo the top of the fuselage, see the pictures.

First I did prepare a cheap wet three ply balsa sheet with elastic bands around the special prepared half “didjeridoo=DJRD”, to give it a round shape.
Then remove one sheet from the inside and make it around the DJRD with rope with some textile on both sides and pack it in a plastic bag with 5 % ammonium.
After about 12 hours repeat the process with the rope a second time and wait again for 12 hours.
Then dry the present for about 24 hours , waiting for unpacking.

And that is what you see on the pictures.

Most important of all is of this method, you make a present, a gift for yourself which you may unpack on a later moment and of which you will be a surprised (negative or positive ) when opening. I nearly can't wait, so exciting.
What is special? Look the side view, a double convex surface in two directions for a single little money. Thinking about that, may be Ed did use this method in the past and we did forget just like almost the whole history!
More to come.
