Flite Test Groupie
Making progress, needs a motor swapped from my nnChipmunk v2 and a little paint (sharpie?). Flight soon!


note: the flaps are intended to be split flaps not built like ailerons (my bad) but they work.

Ready for maiden (hopefully tomorrow). Starting with the motor/ESC/prop setup that came from my nnChipmunk v2.


Will start on 3s to trim and check throws before 4s.

NTM 3548 1100
Plush 60a
9x9 APC

I may paint it or weather it later, but the sharpies did a decent job for now.


Lol, love the chalk board.

We need to adjust the pod depth for the NTM 3548. It's sticking out way to much.


You did a great job on the weathered look man! I'm definitely going to look into doing this on a future plane.

Wanting to build the nnKi-61 Desperately !

Hi there,

Fell in love with the Ki-61 instantly....very very long love affair with this aeroplane since I was 8, when I drew a complete cutaway drawing in Paintbrush 1.0 in DOS (Remember that ?) from a copy of my Dad's Air International...

At any rate, I'd very much like to request the plans, because I've got a twist on the design I'm determined to try, and of course post photos....

I love slope soaring, and sort of don't entirely believe in / trust in electric motors...and I've long wanted a Ki-61 sloper.

My idea has been at first to try out designing one in Coreflute, but I've lately become enamoured of the Nerdnic Wing, as first seen on the P-39, and now the P-38.

So here's my concept :
  • Fuselage : Formers in 3mm Coreflute, depth adjusted, and with intervening spaces + spinner cone in scrap EPP foam blocks. Servos for Elevator and Rudder. EPP, and strategic bits of the fuse covered with 3M Fibreglass Clear duct tape.
  • Wings from DTFB, as published, with Fibreglass reinforcement on LE and flying surfaces. Aileron only, 2 x servos.
  • Canopy structure as published, using clear plastic sheet.
  • Tail surfaces also from 3mm Coreflute
  • Covering : Chrome silver mylar tape, pieces of green tape for camo 'spots' (alternately green-grey for a clean one), self adhesive signage vinyl for Hinomaru, and Kokutai markings.

Net result - a fantastically tough, light warbird sloper, hard to kill, with scintillating glider performance.
Worst possible result would be a very nasty crash landing into a tree, requiring a new wing, which at NZ$5.00 per sheet of DTFB, is not so bad.

So, do please send me the plans, and very glad to launch my build log in conjunction with this beta :)
Please do send me a private message for opening response.

With thanks,

Auckland Slope Trash

Hey Nic. Any way to get the plans for this? It looks really cool and now that I have the black widow done I would like to build it.

Big thank you !


Big thanks to NerdNic for the plans link sent - its on the Nerdnic Website, do all have a look.:D

Its going to be wonderfully fun this weekend, I've got everything lined up to make this happen :
  • 3mm Coreflute (NZ$10)
  • DTFB Sheets (NZ$5 each)
  • EPP Foam Blocks (Free ! Recycled computer packaging - nice BIG blocks!)
  • 3M Clear Fibreglass Duct Tape ($14/reel, and a little goes a long way)
  • Clear plastic sheet (10 cents)
  • Covering / marking materials (tape, signage vinyl, etc - free and/or cheap)
  • Printer !

Looking forward to this a LOT - the nnKi61 is gorgeous, and will make a spectacular sloper. :eek: :applause:

To all here - want me to post pictures here only, or a build log elsewhere ?

With thanks,

Auckland Slope Trash

christmas nn ki 61

This ones for my son for Christmas!

The speed wing is very rewarding to build you get a much better finished product, and flight characteristics! At first I was a little intimidated about the speed wing but now that is all I will build! I just watch the time lapse build on youtube if I need a refresher. Thanks again Nic .

Sorry for the vertical picture.
