I built this kit several months ago. It was a challenging, but fun, kit with a lot of pride when completed.
I have not launched it yet but plan on soon with the G77R-7.
Pro: Very challenging and a lot of balsa carving, however with patience looks great
Con: The white strip decals for the forward section are several small pieces with a few long. It's hard to make the pieces work to look like the photo. The pylons for the ram jets are pre-slotted a bit small which I realized a little late. I suggest cutting the slots so they insert deeper into the body tube and the ram jet tube deeper before gluing or epoxying.
Pro: Looks awesome if you take your time
Con: A lot of masking
