    PLANS
    http://www.nerdnic.com

    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 have shared with me as well over email, 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.

    New features in v2:

    HATCH
    -Updated version of nnP-39 style hatch

    v3 SPEEDWING
    -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

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

    TAIL FEATHERS
    -Double layer foam
    -Added airfoil

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

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

    BUILD DIFFICULTY
    Beginner – You’ve never flown a plane before, let alone done a scratch build
    Novice – You’ve flown a plane but have no experience with scratch building
    Intermediate – You’ve flown and built a few foam planes before
    Advanced – You’ve mastered the standard foam build style and are looking for a new challenge
    Expert – You’ve mastered all build techniques and aren't afraid to improvise or tackle tedious builds

    This is a intermediate to advanced build.

    PILOT SKILL
    Intermediate

    MATERIALS
    6 BBQ skewer
    3 sheets DTFB
    1 flat aluminum 1/16" x 1/2" x 24" (speedwing)
    1 Basswood 1/8" x 3 x 24" (basic wing)
    1 sheet poster board
    1 2 liter bottle
    Push rods
    Control horns
    Hot glue


    FAQ
    Is the v2 swappable compatible?
    It will accept a FT power pod as well as a new pod I have designed. The new pod is larger to accommodate a bigger battery.

    Is this a good plane for a beginner to fly?
    No. The nnChipmunk v2 is a bit too advanced for a beginner.

    Can I build the basic wing without the basswood spar?
    I would not suggest this. The basic wing is much more advanced than a standard FT style fold over wing. Some of these improvements create weak areas that need to be reinforced.

    Can I build the speedwing with no aluminum?
    No.

    How come no flaps?
    After testing the plane thoroughly I am confident it simply doesn't need them.

    There is a plane I want you to design, what’s the best way to suggest it to you?

    I've got a few that are mostly done, just need to get the last details in order. There has been a large delay this year in my releases as I had to move a few months ago. I'm all settled now and have a proper work space for filming and what not.

    Projects that should be coming out in the near future:
    P-38
    F-86 (micro EDF)
    DLG
    Ki-61
    Corsair

    I have 2 other planes I would like to build before I build the chipmunk,so it mite be awhile before I get to it.When I looked at the plans I only saw one side of the wing.It would be handy to have a left and a right instead of trying to reversing one side.

    I guess the idea is that it would take less time to reverse than to cut out and prep the plans for the other wing. I can look at getting it added as a separate sheet for those who might want it.

    Looks great! As a tip, start with a few clicks of up elevator trim on maiden to insure she climbs right out of your hands.

    Let me know how it goes!

    Two control horns came unglued. Luckily I noticed it before I launched it.So I didn't get to fly it .

    Emax 40 amp ESC and Turnigy D3530/14 motor with a 10x5 prop,2200 mah battery. Waiting for a calm day to come around again so I can dial it in a little more.
