Seems like there is a huge variance in CG from kit to kit due to the density of wood used. On my F90 / Saito 100 I used a rudder servo on pull-pulls under the canopy and had digital MG minis in the rear for the elevators. Battery was on the wing tube, CG was 7 1/8". Due to it being super light it flew excellent 3D (excellent parachutes, elevators, harriers upright and inverted, TR no problem, great waterfalls). A battery failure killed it. IMAC plane? Nah...but that's not why I bought it.
