I'm taking mine to a flying display next weekend so I'll weigh the bits & get back to you. It had another 4 flights last weekend & it was good to get it back in the air.

Mine was built as light as possible to fly on the limited power of the speed 400 motors & some compromises were made. For example, your tail surfaces are a symetrical section as per full size & sheet covered, mine are flat & film covered. Likewise, my wing does have some open bays which are covered in film, yours are fully sheeted.

For all my hard work though battery & motor technology has advanced so far yours may be stronger & lighter with lipo batteries. Mine carries 2 1/2 pounds of nicads which will not be hard to beat! - John.
