I just realized that I didn't answer your last question, would I build another. YES, I would. Matter of fact, I have a hankering for a Ringmaster JR Flash to replace the one I crashed on it's first flight when I was a kid. His kit of that looks great!
Also, I was looking at the pic of the one in the post above mine, and realized that I also altered my rudder a little bit to make it the shape of the one on my big Ringmaster. Not sure which is right.
