This is an engine mount demo.
  It will fly, but the tail wants to oscillate. [Yes, I did it, again.]
  The engines are mounted to a rotating boom, so the engines go around the boom.  A simple idea, but I had not seen it anywhere.
  Maybe this will give some of you ideas.

Thank You, 2, @Wpieter
@Loopy200 I Didn't realize that was the smoke exhaust. I thought I messed up changing the exhaust color(colour; for the Brits)
I have a fliable variation now. Augered Tern
@ProvingMars well the jets were emitting a black fire so I guess yeah this happens to me too but I don't know why
Thank You, @Genrich Titov. ...for the vote.
So we need inlets, even when the intakes are open to air? @Loopy200
@ProvingMars no problem just puts some inlets on it to make the engines faster.
Thank You. And, again, for the vote.@Loopy200
Nice, me likely!
