Back in Production!
The latest generation in the Lumberjack saga that began high up in the Colorado mountains back the year 2005. Version 3 kit is a modern refresh of the classic Lumberjack with the same quick build and great flying characteristics. It is back and better than ever with latest in mods and improvements developed over more than a decade of hard core flying.
Cores are precision 4 axis CNC Hot wire cut from Expanded Polypropylene Foam (EPP). EPP allows the ultimate in durability and to survive even unexpected “landings”. EPP opens up flying sites that are not friendly to traditional built slope aircraft. It is the the go to material for flying in the Rocky Mountains.
The Lumberjack is a great front side sloper especially on big hills and comes alive in the Dynamic Soaring Groove. Even the heaviest builds can fly in surprisingly light air with experience.
The 6 panel wing design allows for a generous CG range that is 200-210mm from the LE at the root cord.
