Balanced mine gear up (cause this is the way you fly, when going gear down it will become slightly more heavy on the nose witch is no problem) tanks full and empty and took the average of both. I'm using the saddles for fuel and wing for smoke.
Balanced her upside down, so canopy facing to ground.
Flying it came out nose heavy so tossed out the 100grams i had to put in the nose.
Now she's as neutral as neutral can be, tanks (including wing smoke) full and empty, normal flight as well inverted.
CG stay's the way it is, not an single click of trim needed, all surface in neutral stand
Got the PB smoke system and in combination with the PB smoke oil it really is amazing smoke, very nice
Really an great and forgiving flyer!!
