Watch that max blade height! My 206 goes into a barn with a door that's too low,so everytime I put it away I have to go through a little dance involving the tie down going from front to back as the M/R head is under the top of the door! Havn't got the numbers in front of me, but 11.7ft sounds doubtful to me, especially if you've got high skids.
Sounds a neat idea: post a pic when it's done!
