I've always determined CG with glide tests for all my kites. So yes, it's valid.

However, I've found that kites with long wingspans and short body like bird kites to be harder to trim than kites with short wingspans and long bodies like deltas and box kites.

Kites with a lot of cloth in front of the CG usually need a tail to improve lateral and spiral stability. Sort of like the rule with planes and the size of vertical stabilizers.

So far I've never been able to trim kites with pusher configuration though it should be possible given that people have built RC ultralights. Having the prop in front of the CG is easier to trim in my experience.
