nnChipmunk v2 Build Kit



Hi friends!

I am really excited to release the nnChipmunk v2 to all of you! The original nnChipmunk was my favorite plane to fly, hands down. This is a sentiment that many of you have shared with me as well over email, here on the boards, and in person. To me, it was the triumphant design that stood tall above the rest. Every time I took it to the field someone would be amazed to learn that it was made from simple dollar foam. The nnChipmunk v1 bridged the gap between "oh that's a scratch build? Yeah.. I could tell" and "Wait, you made that? That plane is cooler than my store bought!" Even though it's not my most flashy, popular, or best looking design, it is still my favorite. 

What's new in v2:

-Updated version of nnP-39 style hatch

-New custom airfoil that's SLICK (no FT style 'steps')
-More streamlined version of a clark y airfoil
-All planes I release with the v3 speedwing will have the same airfoil
-Easier to build

-Same airfoil as v3 speedwing
-Thinner profile
-Basswood spar 
-Can handle 500w of power vs 350w on normal FT style basic wing

-Double layer foam
-Added airfoil

-Added canadian canopy (featured)
-New 'framing' technique

-Wing notches to fuse cleanly
-Fuse length slightly reduced to allow for kit creation
-FT power pod and new nerdnic pod compatible

Awesome job Nic! The kit looks great. Are you using Adams Readi-Board?

Great job Nic and I couldn't help but notice the profile of the P39 Air Cobra on the wall behind you.

Heh yep! I decided to make it part of my logo after I designed the nnP-39!

Just finished the Chipmonk V2 in finest English heavy foam board. Not weighed or flown it yet but it will be ok - nearly always is. Will fly tomorrow as setup complete. Loved the build and design improvements from FT style, makes the wings look lovely and more to scale. Brilliant work Nerdnic.
The versatile battery compartment has allowed me to mount battery (2200mah 3s) inside the powerpod and 45a Esc on the bottom of the pod - the pod now just slides in leaving a millimeter or two for air for esc. This has given me slightly nose heavy CoG - perfect.
I also reinforced sides of compartment lid with BBQ skewers sunken in and glued to form flush rails the full length of both sides of the lower plate. Just run hot glue gun tip down foam to form a trench and glue in skewer - dry on flat surface.
This is a really rewarding and enjoyable build style. Does get you thinking too. Shame I cannot upload photos as she turned out real pretty like.

Your Ki-61prototype on nerdnic.com is looking beautiful too - hope that is released soon.

Thank you.
