Will someone please help me find the CG and MAC for my delta, I tried doing it on my own, have looked at all the explanations on how to do it, but i am still have a lot of difficulty. The model sizes are as follows"

29' length
48' wingspan
6' tip chord
6' wide where the motor mounts

It would be extremely appreciated if someone to do the math for this. And if it is not too much trouble, show me the formula. Also, the trailing edge is straight, no sweep. Thanks soo much to anyone who helps.
