Ok, the plane is just over 7.oz and the battery is 1.8oz. for a combined flight weight of, 8.91oz.
I also went up to a 7x5 prop today, and it is so much better. I flew in 10-15mph winds, and it was great. The extra prop and weight made it a blast in the wind. going vertical is no problem.
WARNING! THIS IS NOT THE STOCK SET UP, I(and I'm sure J.) do not recommend these modifcations. When you go outside manufacture specs its a lot of work to get things just right. If you purchase everything from J. as a matched set, you wont have any problems.
That being said the reason I made these mods was to make a small plane fly like a big plane. I over power my planes because I fly in the wind. I also wanted longer flight times. Today I think I went over 12 min.
J. Karpy makes some of the best planes on the market. I should know I have 3 of them, and I still need a 3DX. Thanks J.!
