3M Micropore or Blemderm tape works perfectly on gas powered planes. I picked up that hint from Dick Hanson who rarely seals hinge gaps and when he does that is what was recommended. Tried the Micropore on my newest 28% Edge and it worked really well on the ailerons. I had to use the Blenderm on the elevators though due to the graphics installed. The Micropore is white vs the Belderm being clear. The Micropore can be removed very easily and leaves very little residue. The Blenderm on the other hand is more difficult to remove and does leave some residue. IMHO, it is more likely that the plane will be planted into the ground or have another mishap before having to replace either and it is so much easier to install or maintain then covering.
