They do look similar and so the Dauntless will fly relatively close to how an AT-6 will.......except the real planes had a sizeable weight difference with the SBD Dauntless coming in over 2000 pounds heavier empty weight. Part of the weight is the difference is motors used. The AT-6 had a 600HP pratt and whitney while the Dauntless started with a 1000HP and finally had a 1200HP cyclone wright radial.
