Can anyone tell me if the SBD-3 Dauntless had folding wings? I’ve never seen a picture or film that shows one with wings folded, and did not notice wingfold actuators on a schematic of the hydraulic system. Because of that I think that it did not but I might be wrong.
Yep, as a former “Tomcat Tweaker” I know they had oversweep. The oversweep function was specifically for carrier storage. The flight function of the wings was a sweep from 20 degrees to 60 degrees. Oversweep was a single movement from 60 degrees to 62 degrees. Flaps and slats could be deployed from 20 degrees to 50 degrees. After that the flaps were disabled by the flight computer as were the wing spoilers (which had the function of ailerons for turning). Turns with wings between 50 degrees and 60 degrees were accomlished by rudder and a split horizontal stabilizer function. Additionally, the inboard flaps only deployed at 20 degrees and were hydraulicly actuated to “bleed back” if a flap malfunction occurred (a 3 degree difference side to side in flap deployment would cause the flaps to “lock out” which held them in whatever position they happened to be when they locked out). The Tomcat was also notorious for a problem with the wingsweep actuators which caused the wings to sweep back out of sync which caused a few to crash but several were actually brought home in spite of this. (All this info is for those of you who want to build accurate Tomcats).
Additionally, the early birds had what was called a “bomb” mode and when the wings reached 50 degrees two triangular panels on the front of the plane inboard of the wing pivot would deploy for further stabilization but later models (BuNo 161… and later, I believe) had this feature removed. The old 1/48 Monogram model had these panels and because of the gearing Monogram used to sweep the wings these things came out every time you wanted to sweep the wings back.

Everything I’ve read about the SBD-3 states no wing fold due to strucural integrity in a dive with early wing fold technology…I think Trumpeter got it wrong.
That is what’s great about this site, questions that pop up that some of us never thought about or just have overlooked. I was under the impression that all US Navy planes had some sort of folding feature for storage reasons but it’s not the case.
Taken from Wiki, not the best place for info but it sums it up very simple:
“Since the monoplane supplanted the biplane in the late 1930s, virtually all fixed-wing aircraft designed for shipboard duty have been equipped with folding wings. Notable exceptions include the SBD Dauntless, F2A Buffalo, and A4D/A-4 Skyhawk (all USN types) and the Sea Harrier (British). All four are relatively small designs.”
And another non folder is the Tomcat as previously mentioned by GM.
