Nice combo Dave!
I would seriously reccomend the horiz stab beef and to move the servos aft of the wing one bay - you certainly don't want them out in the slipstream - do you?
I added wood to the horiz stab and laminated top and bottom w/carbon roving.
Also beef up the wing mount.
I used carbon gear to .60 size funtana $23 from Horizon
I went Saito 82A and am very happy with it.
