Hey i just built this plane here and i have a couple of questions. First question is how do i put everything in there? And second how to balance a flying wing. Is this design stable? Because when i did test glides it seemed to work ok but once the electronics were in i was not so sure.

wrll for one it's not a delta.and unless you used an airfoil with some reflex at the trailing edge you may have some control issues.the rest is upto you since you are the designer

If it flies well without equipment, remove the equipment and see where it balances - then put the equipment back and balance it in the same place

Ok well il try the balancing with equipment. Thanks.And i see what he means by not a delta. I put the upward curve on the back for acting as a tail wing.

generally flying wings balance some where around 12-15 % of cord. much further fwd than conventional tailed designs .and YES you need some form of reflex in the airfoil.
