i've bought it in january 2008, and done the first flight in june 2009.
if they know this problem , why the didn't want to replace the cell, i've purpose them to buy another complete plane ( cause i don't want to put in the air the main wings, because i don't know if they've an internal failure) at special price, but their answer was completly wrong(825 for the fuse without retract/fuel cell/gear door and without speed airbrake)
no costumer service!!! and very dangerous building without any control possible when i receive the plane, cause the axle was already "glued"

the hystory is more longer than that cause i 've to wait long time to have the right measurement elevator axle , because the two that were supplied in the kit were not at good size compared to the bearings provided in the fuselage, and i've sending the 2 wrong elevator to my french distributor.
