That is what we tried to do.....the only problem we encountered was no being able to properly shape the leading edge of the moveable surface as Matt did....we did not want to grind or sand into the fiberglass, not knowing for sure what was underneath......as it comes, with the very firm overhanging leading edge, almost firm like C/F, not the more flexible skin like on the Eurosport or Kingcat, the radius of the leading edges are too fat, and does not allow any travel.....

So we did build up the aft trailing edges with balsa to the proper depth which consumed a fair amout of time to get right and sanded, and holes relocated, since each surface is a little different, and in fact, each of our kits has a little different overhang, leading to a varying depth of the trailing edge......
