That's going to be a very challenging build if it's your first. I started on my Top Flite Spitfire as my first build. After framing up the wings, I took a break from it to do a simpler build, a 4 * 40. It was far easier, but allowed me to make a few mistakes before going back to completing the more complex build.
I too have an 85" Dauntless kit from DP Systems. I still plan on doing one or two more 60 size kits before tackling it.
