the picture does no t show very good but im using a ring on the inside or the mast.
is on the weak side but ive asked the machine man to make me a stainless 16mm rod.
I will cover the head of the mast(keel) connection with carbón and fiberglass.
i did torsión on the assembled fuselaje and it cracked under light torsión.
no Little amount carbón or fiberglass will solve that!
To little material on the sides, is 4mm of Wood on both sides of the connection.
I will step it up to 13mm its easier to do it all over again!
it will be a crossbread between a beluga whale and a hammer head sharK !!
Crossbread V2 on the way!
