[NSRCA-discussion] Hinge Seals

[Rcmaster199 at aol.com]

Jay,
 
Many moons ago, Don Lowe and Ron Van Putte were advocates of sealing the 
hinge gaps. In essence, the seal promotes improved control authority. Most 
importantly, it produces consistent response from the control AND flight surfaces by 
practically eliminating differential lift that may result from unsealed 
set-ups.
 
Seal material may be almost anything that is flexible and light. My technique 
is pretty simple: I take a strip of clear iron-on film material designed for 
foamies and fold it in half lengthwise, glue side up. I run the fold over an 
edge to set and then insert it into the gap. With a thin straight edge holding 
the film in position against the hings, I use an iron set at the low settings 
required for foamie work and gently secure the strip of film aginst the flat 
surface of the wing/stab/fin post facing and the bevel of the control surface.
 
I prefer the low temp adhesives of foamie clear film covering because there's 
less opportunity to damage the paints I use in my finishes

I have a new ARF that says to seal the control surface gaps with hinge 
sealing tape. 
What is “hinge sealing tape”? (I have some foamie hinge tape – is this OK?) 
What is the technique for doing this? Do you seal both sides? 
Is it necessary?
