hi miskin
it's not important to fibreglass centre section of wing just look at main spar and put some pink zap on it (from the hole of wing servo cable.
look carefully at stab, my was hard an i don't put brace on it, but if you bent it put the brace(a carbon tube 4mm on underside)
my edge died last week due too an engine failure on hovering at 5 mt (15 ft) and crash after one year of honored service.
this plane fly very well,make aerobatics smooth and a nice limited 3D. the only think i disagree is that is a little heavy on landing,if you slow to much stall
look at pics of my edge post previosly.

best regards and happy fly
