Doughlas A1 H Skyraider 1:12 Video Built Threat

Ok guys, the decision is made!

After my attempt to document my way to build warbirds during my activities of the last ( Mig 3) Workshop, I recognized that I

-first did not have the right software to create HD Movies for youtube
-secondly was too busy to engage in real time support with the participants
-third is that youtube HD was not that far

Now I decided to build another bird form 6mm depron ... BIGGER
and more detailed.

And my target is t to make an over all video documentation as a guideline
for others which would like to follow....

Fuse - Inner Structure

Second is that I engage into the fuses inner structure

Necessities for this are:

-a defined accu position
-same for the servos , esc , RX
-third is to get a good structural connection between the wing and the fuse as the motor

Assembly of The Inner Structure

As soon as the struture is detailed and printed out I usually can't wait to get the first parts. So I performed a pre assembly test - changed some smaller things and set up the skeleton

Quite some effort but it pays as you will see in the next steps...

And one part more in the loose assembly

Of course there also would be a possiblilty to create the cowling as vac formed part or from composite .... but I decided to show you the variant related to my technique .... alternatives are your modification
