Sheesh Karl.. Tamiya must love you for all of their tape you use! Excellent work my friend.
OK, Tamiya Corsair tips!
First, in the cockpit (I built mine OOB) I took a piece of Tamiya tape and fashioned a map case out of it. A little time spent detail painting the office yields a very nice finished product.
On the tailwheel, the triangular blob on it's backside is actually a wire loop to tie down the AC on the deck. I ground it off on mine, and replaced it with some wire.
On the main gear, I added brake lines, tie downs at the bottom of the gear leg, springs, and anti-rotation cables from stretched sprue.
The back of the cowl flaps are devoid af any detail, so I cut some tiny triangular pieces of sheet stock, drilled a little hole in them, and added a cable to open/close the flaps. Also scribed in the details between the flaps.
Another big thing when modelling the kit with the wings extended, is NOT to follow the directions on assembly. I learned this trick from Drew H. Instead, assemble the inner wing stubs first. Then, assemble the wing rib/gear bay side with the spar and firmly glue it to the wing stub. Next, take little squares of sheet stock and glue them to the inner surface of the wing halves- with some sticking out approx. 1mm. This will support the outer wing halves when attched and keep them aligned with the inner halves. Next, glue the top outer wing half to the inner and to the spar, making sure to keep the top wing halves even. Then install the bottom wing half. This aligns the wing halves top and bottominner to outer, and any errors are on the leading edge where it is much easier to fix. Sounds a bit complicated, but unfortunately I do not have any photos of how to do it. Hope my description makes sense!
