Sometimes things happen really fast....
I took some hours thinking what great but cheap conversion could be made,
and got a Sword Northrrop N9 box;
Flying wings, I am a fan...

I check what engine could fit and...
the Heas 011 is the best.
I know, a german engine...in a US plane,
but is there some alternative history writter ?
the kit waits its story...

the sharkit box with the early engines was of course a big help.

Jumo 004 was fitting to but required to rework the air intake,
because of its length.
The J35 is two large, the shape of the wing would have need to be enlarged,
and also the landing gear and others elements.
Shame....maybe another kit to come ?

The BMW of the Volksjager fits two,
and may have be a better choice, because with two Hes the N9
(its reconstructed version in fact...)
is obviously overpowerd....
but I dont want to go deep in the "real" plane designing,
to focuse on the kit.
Nene engine is two fatty,
it would have need to change the intrados of the wing,
so by by the cheap conversion.
next to come later...
