Both of these planes are about 2 grams heavier, perhaps from the heavier rods. CG seems to have been shifted slightly rearward as a result. I won't know how much a difference that'll make till I fly them.
I also noticed that the plane is more tail heavy as well as compared to my first version---My plane required a nickel for nose weight to get the CG correct instead of a dime that my first one used...The new plane requires more nose weight even though the newer planes come with a 250mAh battery instead of the 200mAh battery in the first versions...I used an Exacto blade inserted in the nose of the battery tray to cut a slot to get the nickel as far forward as possible...

Trying to get the maiden in tomorrow...I'm going to fly off of the landing gear for the first couple of flights to make sure that the CG is correct...Even with the CG spot on you can get this plane to do the "Sabre Dance" if incorrectly hand launched...I don't want any surprises!!!
