RE: Sig 1/3 Spacewalker
Here is the information from the manual
Recommended Control Surface Movements
Elevator= 1 1/8" UP, 1 1/8" DOWN
Rudder= 2" LEFT, 2" RIGHT
Ailerons= 1 1/16" UP, 15/16" DOWN
The control measurements listed above should give full aerobatic capability if your Spacewalker is properly balanced. Test flights may indicate a need for more or less movement, depending on individual model performance and personal preference. NOTE: If you have built your Spacewalker with the short (4-bay) ailerons, increase the throws given above by another 3/8" in both directions.
The CG is 4 1/2" to 5 1/5" aft of the wing leading edge. Since the wing is a big ole Hersey bar, you can probably measure this from the tip or the fuse. I would measure this from the fuse to be on the safe side.
If there are any other questions please let me know. The kit I have had all four blue print sheets and all documentation. I will post some pictures later on tonight.
Hope this helps.
