I just bought on ebay an old Sig Akrobat. I say it’s old because the box looks like it’s been around a LONG time… but no dates on it. Kit looks to be pretty complete except there are no hand controls (pardon my lack of proper terminology… this is my first plane… and first post). Anything special I need to know about this kit/plane? Any tips or suggestions? I look forward to building this plane and using this forum. Thanks in advance.
