Wow, even I am impressed with how well this foamboard sub-250g RC plane now flies -- after a few modifications. Even with FPV gear fitted, it would still come in at well under the target 250 grams so won`t require registration in the USA, Canada or Australia. If anyone wants the plans for this model then let me know and I`ll publish them.
