I did not plan very well on my build and I ended up in areas that became harder than if I had planned, e.g. installing the greenhouse glass after I glued the two sections together, painting the doors thinking they would fit, painting the armament supports before installing and realizing they did not fit. You need to always plan about four or five steps ahead of where you are and think about what will be the outcome when later on you have to go back to the assembly you just finished.
It was a true learning experience for me which I failed often, but in the end I did learn much and hopefully my next build will be much better.
Good luck on your build and do not get impatient...I did and messed up decals and the weathering on my tailboom because I did not want to wait for ordered decals to arrive or until the next day to buy pastels I thought I already had so I tried the Academy decals ehich silvered and tried my airbrush and got the boom too dark.
So in the end, my standards kept slipping to the right. That is what impatience will get you.
