I have never built a B-24 but I have built about a half dozen warbirds. The manufacturers were Top Flight, Byron, PICA and Yellow. As you know, the Byron and Yellow have glass fuses and other parts, the Top Flight and the PICA are all wood. While I would characterize the building of the glass vs. the fuse as somewhat different, the time and effort it took me to build all of these were very comparable. I think the big difference is up to the builder particularly with respect to the degree of scale and detail the builder plans on putting in. I tend to add alot of detail to my warbirds. A long way to say it, but I wouldn't expect your bomber project to take any longer than any other advanced kit would take you. However, if you have three guys building, then obviously you will finish sooner. A short war story: I have a friend who had a close friend who flew a P-51 (not in WWII but a referbished one). As a gift, he and a couple of his friends built the guy a Byron P-51 replica of the guys real P-51. They put in all the works, including the 4 blade reduction drive thing. They only had two months to get it done and on the morning of the guys arrival, they opened up the hangar door where they had been building and taxied out the Byron P-51. The paint was literally still tacky, but they got it done. Good luck. If you guys work real hard, you may get it done too.
