Congrats on your new plane. I hope you'll be heeding the advice already given here, I know I will be. I have been maidening all my own planes since my trainers & have maidened six more planes since that time. I am currently working on getting my first Warbird assembled & ready to fly, but this time I will be getting some serious help from an extremely experienced Warbird pilot. He will maiden & trim it for me, & after that we will be flying it together how ever long it takes me to get comfortable with it. It is a 60 size P-51 Mustang with .78 two-stoke engine so it should be fairly hot. Too hot for me to go at alone I'm thinking so I will be taking advantage of the good help available to me. The P-40E is next on my list, as soon as I can get away with putting another bird together. Good luck with yours, do it right they're beautiful airplanes & I'm sure you're going to have a great time with it.
