around 4lb 14oz for motor prop spinner backplate and mufflers.

If you get a chance I am still curious on your hard numbers. I have no problem checking or setting the CG I just want to know where in others opinions the best IMAC position to set it to so I don't have to move to much around after the maindn. I am guessing the ruder will go pull pull with the ignition batery on the motor box and the receiver bateries on the tray.


Thanks
