Video of my version:

Yet more springtime flying @ Torbacka 11.4.2015

Nice weather, dry enough grass, sun is shining, planes flying great..

Nakki II maiden flight & video

Here ya all!

It is my great pleasure to announce maiden of this small & quick project. It was rather nonevent event as it just flew. Nothing special. Video shows everything needed to show.

Nakki II plans updated

I finalized production plans of Nakki II. Changes to beta-version were extremely minor. I did widen parts A, B, C by 5mm and adjusted some of aligning holes to better suite cocktail-sticks I am using. Finalized product page can be found at here. Only thing remaining is to wait for suitable weather for maiden flight.

Final weight, with servos, receiver, 3S360-battery, motor and all installation stuff was 208g which results to wing loading of 11,6g/dm².

Third day of this Quick project (Nakki II)

Pics tell everything..

Second day of short project… Nakki II

And second day of this (hopefully) short project.

Short project, build day #1

Just wanted to build something quick as I have not been able to build anything more impressive for a while. Dish of day is Nakki II. Which is translated easily to Sausage II. This has been briefly mentioned in this blog some time ago. See here.

This design uses ‘perussiipi’ which is basic wing manufactured by local vendor from styrofoam. I do dislike styrofoam, but in this case it is ok, as this is sort of ‘classic finnish modelling stuff’.

I will compile extremely short build log into this blog.

New design, Nakki II

This is an new & improved design of my oldie plane. In 2007 I designed and built an wonderful small electric glider. It was blast to fly and my favourite small plane for some time. One interesting feature was (and is) wing construction. It is based in popular (here in Finland) Perussiipi ™ concept. Ie. there is pre-made styrofoam wing element which is just missing TE & LE spars and possibly torsion sheeting using paper/cardboard/balsa. Fast and economical as one element costs (if I remember correctly) approx eur 3.50.

Using cad and plenty splines etc. this is an modernized version of original.

I am not certain whether I will make actual plane, this was interesting drawing excercise.
