1/4 scale Kranich II
« on: October 21, 2010, 11:52:05 AM »
Alright, this is this time of the year again !
Moving on slowly on my "wish list", one of my winter build will be the DFS Kranich II...
Everything home made of course, and to the usual 1/4 scale (that's 4.5m WS).
All wood construction (plywood).
Plans are being finalized and are made using Martin Simons drawings, wood is ordered  :D

A quick view of the plan :



Stay tune for more in about a month!  :D

Ah. I knew you were up to something  :D  :D . Looks like it will be a nice model, and big too for 1/4 scale.

Hi Fred,
Will there be a short kit out of it?

Salut Fabrice,

Well, maybe, it is planned, but there is still a long way to go  8-[
I'll go with all plywood/varnish finish on that one too.

Printed the fuselage's plan, and that's a fat beast!  :D

Hi Fred.
When you are printing out your plans, do you have to make sure it will fit on a standard sheet of paper like A1 or A0.

Hi Alan,

No  :D
Well, Yes.. Ok, confused now ?  :P

The only limitation I have is the width of the roll of paper (90cm in theory, but with the printer margin, that can be less than that... Always use 84cm as a max...), but in lenght, driver take up to 15.6m  :mrgreen:

Thats interesting. I was at my local stationary shop a few weeks ago. They have a plotter there and they said that the larges thing they can plot is A0 size. That does not make sense to me. The roll of paper that is in the potter is many meters long so it should be possible to plot something that is as long as the roll of paper, of coarse the width will be limited by the width of the roll.

My experience with the guys who have plotters in shops etc, is that they don't really bother having a look at what they can do!  :evil:
Spent month looking for someone to print our plans in this country !
Thanks to Dave, now have my very own plotter  :D

Ok, I though I'll give an update on that one !

Progress so far slow, because of the kits and Christmas, but lots of work done this week !
Formers are on the way (hate doing that!) and wings are almost fully completed !

For the wings, I'm going to change my usual way of doing things, as I had to rethink that because of the gull wing configuration, but they are going to be built flat, on the spar, like some of the Schneider kits  :D

Printed the plan the other day.. Looking forward to start that one !  :D

Alright, another quick update  :D
Moving slowly, hate doing the formers ! Spend roughly an hour by former (well, for the one in the middle section with the wing root etc :!: ).
And find an issue with M. Simons 3 views. My root profile is too thick (about 16%) and need to be around 13%.
So, change that before moving further.

I also made my choice of profiles, and going to try a new combination!

The obvious MS535-2 from root to mid wing (where the gull start) to HQ35-10 at the tips.
That gives a nice curve, but I might change the tip to my own symetric one.
Spars and notches are drawn, and I'll get started when I finally decide what I'm going to use.
Alright, I go back to my formers !  :?

Hey Bill,

I'm using Turbocad  :D
V6.5 used to be free (can still be found on the ternet).
Version now is 17 I think, but I only use the basic tools.

Still trying to learn Solidworks  :!:  :!:
