Hi Pete
Yep this is about right. Alan designed the Elan with the long nose and short tail to try and get round the need for having any extra weight up front. Our demo model with the supersport in it started off with the rx pack and the lipo up front but I found this to be too nose heavy so we gradually moved them back to the centre section of the fuselage. My thoughts on C of G on a plane like this is that you really do need to play with it a little to fine tune the plane to how YOU like it. Start with it slightly nose heavy and see how you go.
Regards Al
