RE: House of Balsa Extra 300L
If you want to see you're expensive plane in about a million pieces thats the one you want to start with.
That plane is a goal to shoot for not to start with. You will be amazed how unstable it is, but is supposed to be that way so you can do extreme aerobatics.
An Extra 300 is a good third<(if you are skilled) or forth plane.
You WILL regret it if don't go through a good training regimen.
