Infernal Robotics Rotatron strength

[Benzel]

I'm trying to make a VTOL Plane using Infernal Robotics, but I stumbled into a hurdle straight away:

 

The Rotatron that should rotate my fuselage (which doesn't contain any engines yet) is clearly not strong enough to hold the weight of those massive tanks. 

So I'm simply looking for a possible solution for this. I've seen loads of VTOL Planes being more massive than this, having no wobbling in their robotics parts. So there must be something to be done? 

 

Thanks in advance

Tweak scale to make them bigger?

What I've done in the past is I used quantum struts to hold the moving parts in place when they aren't moving.

I have to ask why you need those great big tanks and that amount of fuel mounted so far from the vessels  center line,  I think a redesign is in order rather than making things bigger.  Use the IR version of KJR  which helps calm things down and many use quantum struts or a variant to stiffen things up
