This is a 7 vs 6 race story compared to a 7 vs 6 choice story.
I was progressing nicely on my 6 project, tail & wings done, fuselage about 30% done on the jig. I got the brainy idea that this process was pretty easy & maybe I could build a second plane at the same time, structures very similar, build them side by side. No prob...
So got a 7A standard kit. Work on the 6 in the morning, and the 7 during the afternoon. Both progressed along, but eventually it got to feel that for every rivet I put in the 6, I felt (precieved) I was falling twice as far behind compared to the 7A progress, even with the 6 head start.
Winner of the race was the 7A, the 6 progressed to the point of being ready for final assembly, panel done and engine to be installed, about 3 months to complete, I figured.
After the 7A flew, another 7 project came in the door and the 6 project went to the back of the hangar. After all, I had the 7A to fly... & I wanted to get my buddies plane done quickly.
I had the advantage of getting build experience and technique from the 6 which of course helped in reducing build time on the 7A, but this in some ways illustrates the advantages of later pre-punch parts kits vs earlier kits. Good luck with which ever project you decide to do!
