I just have to ask, and I'm surprised that nobody else has asked this. You look like you are doing a great job putting your plane together, and it sounds like you have a couple of fairly advanced planes about ready to go. It also sounds like you are new to the hobby. Are the Extra and the Hellcat your first planes? If so, I hope that you get some help with learning to fly using a trainer and work your way up to these birds.
Good luck
Edit - I just saw another of your threads, and I see that you also have a Nexstar and a PTS Mustang. Sounds like you are all set. I applaud you for jumping into the hobby with both feet
Good luck
