Carter Hummingbird - 1/3 Scale

This project is just starting up. We still have a lot of calculations to go thru to finalize the design and duct/wing/empennage profiles...

What does everyone think?

Neat project, looks like a design challenge!
Especially the contra-rotating propellers and duct. Have a look here for some inspiration: http://www.rcgroups.com/forums/showthread.php?t=1510248

I knew I saw this unique design somewhere before: http://www.rcgroups.com/forums/showp...&postcount=100

Challenge is an understatement...

Nice contra-rotating ideas...

Still working on this. We are seriously behind at work. Most of my design time is there and not at home. LOL
