Engine (Only) Weight: 46.0 oz I moved the servo tray to the back so all the sevos are mounted behind the wing bolts and the battery and receiver is back there. I haven't CG'ed it yet waiting on custom exhaust... for your information never buy the custom exhaust after you buy the plane go a head and buy the exhaust about 2 week prior to buying the plane then you should have the exhuast when you need it...
