Graupner ASW 22

Picked up a partially finished Graupner ASW 22 off fleabay recently and justed finished getting it assembled. However it was missing the sheets pertaining to control throws and C/G. It has a full flying stab and one instruction refers to "cutting out the incidence gauge and setting the stab incidence" before flying-of course this guage is missing-any ideas?
Also, roughly what should the finished weight be?
Thanks
Mike

Wow,
The version with the full flying stab.. That's an oldie! I had one back in the mid eighties. I flew the heck out of it. I don't remember even using a incedence meter. Can't help ya there. As for the CG. Since it has a straight LE, 30% back is a conservative starting point. Keep an eye on the fuse. Over time, the plura material gets brittle from the UV rays. I miss my 22. I also had the second version which was electrified. It was a real screamer and thermaled well too. Unfortunately, It was lost in a mid-air with Larry Jolly's 1/3 scale ASW-27 at the Los Banos scale meet back in 97..

I might have a spare.
I remember modding mine due to damage of some kind.
The CG is 65mm from the root LE.
What does the dihedral look like Mike?
I'll take a photo of the gage with a protractor and report the angle.This fits from the Vstab TE to the top of the pivot plate.
I can't believe the flying surface throws are no where to be found!I've checked the german build sheet & the multi language sheet and no joy
Hard to believe as these kits were very well documented.
Stay tuned.
Skies.
Jay.

There were about a dozen little 6"x6" sheets -like note cards- with a different step of construction on each in German! There are several gaps in the number sequences and I am guessing those pertained to the control thows.

Mike,

after reading this thread I asked in the german messageboard RC-Network and got an answer by a user named Steve, that he owns this model and is going to search for the data you’re looking for this evening.

He asked for the wingspan. Is it 2,60 Meter (about 102'')?

MIke,

I don't know if this will help but I have the I-Care ASW-22BL model (2.8 meter) and here are the recommended throws... I realize it's different than what you have but these throws may serve as some baseline values.

Ailerons 12mm up and 6mm down
Elevator 6mm up and 4 mm down
Rudder 25mm each side

what’s the difference?

From that sketch I would say the incidence is 2,5 degrees.

360 degree's are in a circle......metric or standard has nothing to do with it.

I believe that burgermike was asking the degree question "tongue-in-cheek".
