VACUME PUMP. I'm not going to give a blow by blow "how to" description. Most modelers don't
have a vacume pump anyway! When covering the control surfaces I drill 3/32" holes in the
center of each hinge slot. Typically hinges ar 3" to 4" apart which works well. If the design
uses aileron torque rods, the control rod hole is also used to suck out heated air. Cover the
control surfaces as you usually would. Start the shrinking process in the middle, and work toward the tips. Insert the tubing from the vacume pump into the a hinge slot. Start with a heat gun, and
as blisters form, turn on the vacume pump. Finish it off with an iron. The trick is to learn when to
apply vacume, when to use the heat gun, and when to use the iron. You also need to listen to the
sound of your vacume pump to know when it is laboring (choked off) and when it is helping you.
I've got airplanes that I did several years ago, and have never been reshrunk. Monokote is the
only film I've done it with, but I see no reason it shouldn't work with other products.
I never really liked plastic film anyway. I still paint half of what I build. Greg
