I tooput a .46 in the nose of one I built some years ago. It was wicked fast, but flew relatively poor, compaired to having a royal .32 in it. The Royal was much lighter, thus the plane flew much better. Unfortunately lost it due to interference upon approach. But I built another, I will post a pic or 2 later.

Hey Sonic500:
I've had 3 Kobras over the years; the first two I had Enya 45CX's in the nose really fast. The last Kobra I put an OS32SX in the nose with a tuned pipe.
Whooooooooooooooooooooooooooooo!!!!!!!!!!!
