The c.g. is at 100mm/3.94" back from the leading edge where the wing meets the fuse. I can confirm that this is a good C.G. to fly with. Aileron throw is shown as 12mm up and 12mm down. Recommended elevator and rudder throws are 40 and 85mm each way respectively but this must be a typo because the surfaces won't even bend that far. Half the value of those throws is more reasonable (20mm up and 20mm down elevator; 42mm left and 42mm right rudder) because this is about 30-40 degrees throw which is normal for most aircraft that I've setup and flown. Good luck with your Zero RACJ.
