Andreas Delta

For Andreas, who is always ready to maiden my planes, I designed a Delta.
He gave me the shape, as well as the profiles and dimensions for balsa laser cutting parts.

I liked it so much that I also wanted to create a print version.
However, initial estimates of the weight distribution showed that the required, far forward CG could not be achieved because of the high weight share in the rear. This was only possible with LW PLA. Thus, the weight can be reduced almost to half.
To keep the weight as low as possible, I screwed a 22 gram lead disk on the front as ballast.
But that was not necessary at all. We added 191 grams of ballast so that the plane would not glide so long when landing. This means the Delta can take a total weight of 1575 grams, the flight characteristics are still good.

Because of stability, and also to shift the weight forward, I recommend printing the front part of the fuselage in PLA or PETG. But in any case
