Weighed it today. 13 lb 2 oz with Enya 155, custom brass muffler supported from engine mount, 1650 5 cell pack, extra HS-56HB servo, 11 oz smoke tank (need to replace), perry smoke pump. Balance is good with battery under fuel tank. When I made the muffler it goes forward to the front of the cowl and then exits out in the tunnel. It probably weighs close to 10 oz. I should have weighed it before final mounting.

Hope to run the engine this weekend to check the muffler and smoke system.
