Watch the CG Steve. I started out with a 2 Cell 2000 and a modified battery compartment to get the battery right forward to achieve the "book" CG. In fact I eventually had her flying with a 1600 2 cell in the normal battery area and I've still got a lot of up elevator trim on - I shall try a 1200 next.
I didn't fit gear on mine but I did quite a bit of re-inforcing of the engine mounts (CF rods and fibreglass cloth because everyone said it was weak spot (which it is). In the event, in my case, it was the front end I bust off but the engines stayed on! See http://www.rcgroups.com/forums/showthread.php?t=402013
