Want to fly RES (F3L, F5L) with one of the latest high performance RES  models? This is your solution! A beautiful design that will catch other pilots eyes as well as it catches thermals. Be sure to check the videos below to get an idea of her performance.

Why is it called NoBo? - The NoBo comes from the same folks that bring us the amazing family of BOW flying wings. We offer their Bow DLG and Repus RES flying wing designs. The NoBo is a little pun basically stating that this is not a flying wing.

The BOW team uses cutting edge software specially designed for the low reynolds number aerodynamics that our gliders operate in. This gives unheard of ability to accurately confirm their ideas and refine designs, greatly improving performance. And the NoBo is proving just this in competitions.

A two piece, two meter wing with an all new, computer engineered airfoil equipped with twin turbulators and super low wing loading combined with a ready to fly weight under 20 oz makes catching even the weakest lift possible. When you're done specking out in that big boomer, use the spoilers to bring her in for spot landing.

NoBo 4K

If you aren't bound by RES competition rules and want even more performance, the NoBo is also available in a 4 servo wing configuration, allowing for full trailing edge  camber/reflex mixing and more accurate control. Pilots report that it handles a lot like a large DLG in this configuration.

Features an all CNC cut wood and carbon tube spar construction and quality, easy to follow build plans.

Specs:

• F3L (RES) => High start
• F5L (E-RES) => Electric motor
• Wingspan: approx. 2m
• Fuselage Length: 1135mm
• Weight: from 330g
• Controls: Elevons, Spoilers (Motor is possible)

Features:

• The spoilers are very easy to control as there is no load change.
  
• Twin Turbulators for improved aerodynamic performance.
• Uses an all new high performance airfoil.
• The NoBo complies with the competition regulations of the FAI classes F3L (formerly RES) and F5L if set up for electric (formerly E-RES)
  

The NoBo specializes in thermal soaring galore! Have a look at these flight videos that show the true performance of this highly engineered design.
