I've got 2 Hobbico CS65s in the tail, a Hitec 645MG in the wing area for rudder, 1600ma NiMh pack mounted on the engine box, OS 1.60 w/ Brisson pitts muffler, Tru-Turn 3.5" spinner and a Pro Zinger 18x6 prop.

Added 12 oz of weight to the bottom of the engine box. I may be a little nose heavy now, but I wanted to play it safe.

BTW, this is on a Creek Staudacher. Pretty close to the same configuration as the Extra...
