Guys

I've been flying my Lightning just for 10 months or so with lots of flights.
World wide there are a lot flying and this is the first we have seen-so it's not common.
I know Composite ARF are looking at this issue VERY seriously, but rather than react without facts the were working on a possible improvement-just in case.
I am 100% confident in it's integrity, the spar is not just balsa-it has glass cloth either side. The tailplane skin adds a lot of strength, if I look inside all my composite aeroplanes they all have balsa spars keeping the skins apart-there is a lot of strength in the skins.
I think caution is a perfectly sane point of view, but some peoples methods of applying this need addressing.

I'm know there will be a response very soon from those that make decisions, it's been worked on for two days.
