Prekin,
I am sure your Zero will fly really good at 11000 grams. My CMP Zero came out at 9500 grams and flew really well at that weight with a 46cc gas engine and a 20x10 prop. Did you get the ESM landing gear for your LA-7? That is the landing gear I am using form my CMP Zero and it works really well. Did you put all of your servo's in the fuselage.? I had all of my servo's as far forward as I could get them and mounted all of my batteries in the cowl with the engine. I still had to add another 900 grams of weight[:'(] to get it to balance at the CG point of 140mm from the leading edge.
