Smile New Design: Stump Jumper

This next design called the Stump Jumper looks simular to an Big Bertha but is quite different. I used the BNC-60 AL for the
nose cone along with the 5 inch BT-60R and the BTC-60A hollow balsa transition to crerate the main body of this design.
All of these parts are Semroc "Classic" parts which I have recently added to my parts database.
So many parts and so many new design ideas, Thanks Carl!

3rd Annual
