RE: Initiating Spin Entry
Splais,
Funny you mention 3D when talking about this. I was going to post this in my last post but 3D wasnt really being talked about here.
I firmly believe that properly set up, 3D capable designed plane, does not need to have an AFT CG to 3D well.
None of the planes I fly 3D with have a rear CG.
If a plane needs an AFT CG to do 3D something is wrong. Or, the AFT CG is compensating for design or set up issues.
