I cover my own planes so I use a strip of covering wide enough to fill the gap with about 1/2" of covering remaining for the trailing edges and the leading edge of the control surface.

Some builders use just common old packing tape. Just be sure whichever you use, that you flex the control surface down or away from the side that you are applying the tape or covering to. Get it down in the gap so the control surface can flex.

I've used tape in the past. The only thing about using tape is that you almost have to do both sides. The exposed part of the tape will collect dirt and vegetation that, in time, will hinder the movement of the control surface. Normally, I'll use a strip of covering and only do one side.

it's a kadet and if the gaps are under 1/8' they should not cause a problem.I doubt that you will even notice any difference by sealing the gaps

I`ve seen this stuff by GRAUPNER, it`s a tape that is sticky on one side which goes on the trailing edge of wing,,the other side is not sticky, but curved to form over the leading edge of the control surface. Anyone know anything about this stuff?,,,,sounds kinda neat,`cept the price is about 30 bucks for 16'

I dojn't think you have to worry about the gaps on a senior.

IT WILL FLY BETTER WITH THE GAPS SEALED.NO MATTER HOW SMALL THE GAPS ARE AIR WILL LEAK THRU AND DISRUPT THE AIRFLOW OVER THE WING AND RESPONSE WILL BE LESSONED.

I use a single piece of covering to do the wing and ailerons (or stab and rudder/elevator), simply flexing the control surface away and sealing with a trim iron in the chamfers.
