Actually even with the conversion and postage taken into account Tower is still cheaper. I wasn't thinking of getting a plane from tower, just radio engine and accessories.
For instance a 6YG in nz(including postage) is $260 but here in nz a 4WD costs $460 without nicads.

Is the Magnum .46 XLS better than a OS 46 LA?? I have never heard of MAgnum. On tower they recomend a 220 volt ac charger as HCAM3110 instead of the one packaged with the 6YG. Where can I get it? thanks
