Can anyone comment on how the Edge II's CG balance with the DA50? I know that one guy used 3 1/2 inch stand off's. Where did the rx battery have to be placed for this? I'm assuming that the person used the stock position for the pull pull rudder servo. Also I'm using the Slimline pitts (adds nose weight). What kind of spinner and prop did you use? Were the choke and throttle servo up front behind the firewall?
