I'm no Sir!
The result of the Test flight is already predicted! If you do wish to try, make sure the CG is correct.
Please, that plane is beautiful. Keep it for later in my opinion.
If you don't want to keep it for later, take a bag along to the field. The reason being............. You know it! 😉

I will accept ur opinion, anyway I'll do the test flight..   Thank you for your support..
