That's a shame. That's why I like foamboard builds, you haven't had to invest hundreds of ££ in the model only to see it destroyed first time it hits a tree (like one of mine was), if you do destroy a foamboard one, it's only £6 and a few hours to build a new one.
Down where I fly there's power lines running across the middle of the field, I've only hit them once (ironically with a tiny quad) but there has aparantly been many a polystyrene plane turned to confetti on them over the years.
