Any-one know which calculator is best to compute the CG for a Delta wing aircraft. No tail just the wing, standard tri-angle wing design.

Just go 1/3 of the span, then balance it at 25% there, it will be close enough to fly safely.

Thanks. I am attempting to make some "drones" to drop from one of my planes and the delta wing design seems to fit under my wing the best. Just couldn't seem to get the balance right. I will try that.

James,

The stability margin for delta wings should be between 5% and 10% MAC.

If you enter the wing tips and tail area as zero into this calculator, you will get the exact location of the CG for any delta wing:

Just for verification, if you enter the values shown in the second attached schematic into the calculator, you will get the same shown results.

You can find more information about balancing any model here:

for flying wings you can use this calculator here choose 10% 15% to 25% cg line, depending on how you like to fly, i would go with default at 20% to keep it safe https://fwcg.3dzone.dk/
