After building the Kelley F4U Corsair with the folded fuselage, and recieving all the complementary comments, I decided that it could be improved upon if I could make the fuselage truly round. I also wanted to try my hand at another big rounded fuselage aircraft. At the suggestion of a couple of the comments from the Corsair Build, I decided to work on the A6M Zero as it would make a great complementary dogfighting aircraft. With just a couple of changes the fuselage came out fully rounded and seems to still maintain the lateral strength. This was acomplished by removing the entire inside paper and taking the power pod plate all the way back to the tail.

I started out by building the fuselage for the Zero using two bulkheads and an extended power pod plate. The power pod plate extends all the way back to the trailing edge of the horizontal stabalizer. This provides the needed stability to replace the inside layer of paper that was removed to allow it to form the fully rounded shape. The horizantal stabalizer / elevator and vertical stabalizer / rudder were added next in typical FT fashion with the front of the power pod plate being the reference point for level.
Here is the comparison of the folded fuselage I used on the Corsair build and the rolled fuselage used on the Zero. The rolled fuselage is actually easyer to assemble then the folded fuselage was.
Satisfied that the rolled fuselage would work, I set out to build the wings. I also decided to add optional flaps to the Zero build for realism.
Now to figure out where to insert the wing correctly.
Wing and rear turtledeck installed.
Canopy and Landing gear installed.
Ready for paint
Paint almost finnished.
After flying the maiden flight, I realized the I had a loose servo..... no wonder I had a bit of a time keeping it straight. Thank goodness the landing went well.
Shortly after the Maden flight of the prototype, I burned up my good 1150 kv motor by running it on a 4 cell Lipo. It made the Corsair fly extremely well, but alas, it didn't last long. I have flown the build video Zero with a 1350 kv motor that I had but it got too hot quickly. I flew the Build Zero in the video with a 905 kv motor with a 12 x 6 prop and a 3 cell Lipo and it did Okay, but not quite as well as the 1150kv with the 10x6 prop did. I think once I get a 850-905 kv motor that is capable of handling a 4 cell Lypo and use a 12 x 6 prop, that will be the ultimate ticket.
I really like the way the rolled fuselage turned out. The assembly is still an advanced build, but with a little patience it is well worth it. The A6M Zero flies very scale, able to do loops and rolls with ease. I added a little more height on the landing gear from the prototype to accomidate a larger propeller. The Flaps do slow the landing speed down and look very scale. Hope you enjoy it as much as I have.
The A6M Zero is a formitable foe to the F4U Corsair. Looks like there might be a dogfight in the air!!
