I see that you have added an additional vertical stab to the bottom of the float plane. I have been told that it isn't necessary on a J3 Cub. Have I been misled?
No, I've also heard that, I just didn't hear it until I had already put the accessory stab on

. Doesn't hurt anything, though, and it tracks really well, plus it makes it look like a REAL floatplane
