I inherited a partially assembled GP Shoestring. I plan on putting a Supre Tiger .61 up front. I don't have the manual. What's the CG?
Thanks...
Get out a yardstick and make 9 simple measurements. Plug them into this online application and you'll have a reliable, safe CG.

If you want a CG range, then choose 20% as the Static Margin for the front of the range, then run the app. with 10% for the aft of the range.
That app. uses the same formulas the aeronautical industry uses. They work for 747s, MD-80s, Cessnas, and our models.
