Weight & Bal Calc ASK-21

Anyone have a simple wt. & bal calc method for ASK-21? The manual is all in German and makes no sense. Power-plane manuals are simple to use with a graph.

Perhaps download this manual in English, and look at page 46.

Thanks.

I found these pages from the manual which are much clearer and, easy to print graph.

Question for anyone:

How does one calculate or develop what I've seen called (Wedge), (Level Line), (Incidence Board)?
To ensure the fuselage is level, and in this case for the ASK-21 is 1000:52. And also in this case there is no reference of exact placement. Wouldn't it change the level if the board is more forward or more to the rear?

If you generally follow the diagram it ends up on the straight taper of the tail boom which is pretty long and non critical.
Measure the length of your level, multiply by .052, and make a spacer that dimension.

Ok, thats sounds simple enough. I've never actually performed a W/B with an incidence board, but thought that the location would be more critical than you mentioned due to it seems fuselage booms taper slight at first and increases towards tail. Just a general observance though and never really measured or compared.

Thanks.

Here is wording in another manual;
The horizontal reference line is the centre line of the fuselage tail cone or a 1000 : 45 wedge template levelled out on the top side of the fuselage aft portion

It is always easier to use a professional to weigh your glider. However, per my owner's manual, I did the math (1000:45/2) on a 50" piece of 2 x 4, cut the smaller piece (approx. 2.25 in) and duct taped it at a right angle. I then took the glider and my assy to our local A&P. He had a fancy digital incidence scale in addition to good aircraft weight scales. Although we went with his methodology, I was happy to see me homemade incidence taper was dead on. Design with a supercomputer, measure with a micrometer, cut with a sawzall...

May I shamelessly recommend SeeG, a program specifically designed for C/G calculation on gliders, one seat or two. http://www.glideplan.com/styled-2/page12/index.html Simple, fast, and flexible.

Thanks. I stay with the paper math.

I would rather spend the $80 bucks on paying for a tow.
