Thanks guys.
I'll post more photos as I progress.
I've got a Thunder Tiger .25 for power. Most likely I'll mousse-can pipe it.... but we'll see how she does stock first. I think it will fly just fine on a stock muffler though.
Remembering back about 12 years.... the buddy's plane I flew had a .28 in the nose on a stock muffler. It flew very well. Another guy jammed a .32 in the nose of his, and it was too nose-heavy, and flew terrible.
I've decided to frame up a vertical fin, rudder, and turtleback spine. It will be fun,

and save a little more weight.
