I have just been out flying an Onas all afternoon and this is what I have decided on. This plane is identical to yours with the plety and rhino 5000´s. The back edge of the battery pack is 2.5 inches in front of the wing tube and the CG is perfect. He has the same servos in the tail as you do. I will make a tray extension that you can simply add to your plane to get the batts where they need to be. I must say this plane flies extremely well set up like that.

Thanks Chip that sounds great. I'll have to think thru the rudder servo on the tail. Right now I have the elevator servo's mounted in the fuse unlike what Tony did so I'm not sure there is room for the added rudder servo in the tail and besides it wouldn't align with the plate location on the rudder for the horns. Any further suggestions around these concerns is appreciated. Mike
