my first plane was 39lbs and the second was about 38lbs with a DA 150 and standard mufflers, which is pretty standard. If you go with canisters most come out to be 40lbs. Also it really depends on what servos you use, if you use 8611's you can save 4 servos atleast compared to most other setups. As for the lightening on the new shipment, we will have to see when they are actually flying but its probably going to be no more then 8 ounces. I doubt most of will notice it, it will just look cleaner.
