A word of caution!

As Marabu is twice lighter that "ordinary" model of this size, one should be always aware that he could overstress model if making brutal actions on controlls while full power.

Wing struts are fully functional like on a real plane, so make them well and secure bolts and nuts against loosing under vibrations.
On teh wing attachment I use nylon bolts M4 ant they are firmly bolted.
On the fuselage strut jount I secure nuts such way that I wrap bolt and nut with kitchen bungee.
It works !

When making a looping, do full power in climbing part of the loop, then put motor on idle, when model goes over the top until it is out of loop flying level again. Now add power.

Knife edge flight is simple due lightweight frame. Just add rudder and power not to loose altitude.

Rolls are easy.

Inverted flight is also done easy.. from top of loop or from a roll. Please, secure wings well with M4 nut at the roots, as inverted flight want to pull wings appart from fuselage joiners. I add rubber washers under these M4 nuts at the root, to prevent unbolting by vibrations.
