F4U Corsair: Gotta' Have Flaps on this Bird!

In my opinion, the Flaps on the Corsair are AWESOME!


F4U Corsair Flaps (1 min 49 sec)


I have started the mod, and the starboard wing has been cut, channeled, hinged and pinned.

TIP: The design of the flaps being divided into 3 pieces on the Corsair was:
1: Because of the gull wing design it required the inner & center flaps to be separate by design of course.
2: The center & outer flaps were divided so the wings of the Corsair could fold up for storage on aircraft carriers.

The point I'm making here is....If your not freaky about scale, and you have no intention of making the wings fold up, which would be quite tricky with foam, then it would NOT be necessary to cut the center/outer flaps apart! They can be left as a 1-piece unit and still function.

Here are some preliminary pics of what I've done so far!

UP-DATE 11/11/2010: I've completed the starboard wing flaps today. I decided to go with the Dubro Heavy Duty Hinge & Cotter Pin . They worked out great when it came time to do the gluing. I was able to remove the cotter pins and separate the pieces while the CA dried so it wouldn't seep into the hinges. It will also allow the removal of one of the flaps if need be?

I used a piece of .020 High Impact Styrene 1 1/2" x 2" for the stiffener between flap 1 and flap 2. I ended up pinning flaps 2 and 3 with some CF rod and glued them together. I liked how solid this made flaps 2 & 3 that I decided to make flap 3 the driver. This worked out great now that I could run the linkage straight on to the servo.

After running the flaps thru numerous cycles I am very pleased with how easy they deploy, not to mention how kewl they look!

UP-DATE 11/15/2010: I got the flaps done and working flawlessly.

That is REALLY COOL. How are you going to actuate all 6 flap sections at the same time?

The 3 flaps are connected together so they'll work in unison. At this time I am thinking I will make the center flap the driver for each side. I'll make a reversed servo for one side and run both servo's thru a Y-Connector to the Rx. One channel is all I'll need.

It's a work in progress Tony. I'm coming up with new innovations as I go.
