Runways- Many RC Airplane clubs have been faced
with the task
of constructing a runway. If your club is one fortunate enough to fly off a paved runway,
consider yourself lucky. There are many clubs out there who have to fly off all kinds of
surfaces such as grass, old pieces of carpeting, old artificial turf from a
football/baseball stadium, or just plain old dirt. Im sure there are other
variations to the theme. Here is some information concerning a material our club uses with much
success. It is less expensive than paving and not as bulky as carpet remnants. You
dont have to water it and its easier to get than artificial turf.
Geolon - This is the name of the material we used. You may have heard the name
Petromat. My understanding is that Petromat is a different material than Geolon and would
not stand up as well to the elements. Geolon is a woven material of heavier construction
than Petromat. Our Geolon runway has been in operation now since 1996 and is holding up
very well. There are a few holes or tears that have occurred because of an airplane
crashing on the runway but this does not create any big problems. The material is easy to
patch. Specifications
for Geolon and photos.
How We Did It - This is a basic overview of what we did to get our runway in place. First
and foremost, get your layout down on paper showing the runway location relative to the
wind, and the starting and endpoints. Dont forget to include your pits when
computing the amount of material you need. Our runway is 60 wide and 600 feet long and we
also used the material to cover our pit area. You want to get your ground as level as
possible. When we started this project, we didnt know what to expect. Had we known
how well the material works, we would have spent much more time and money to really get
the ground flat and level. Spend the extra time to get the ground cleared of weeds, level,
and compacted.
In addition to
the material itself, you will need 12" spikes (big nails), some 1" diameter
washers for the nails to go through, and what can best be described as large staples.
These staples are 6-8 inches long. You should place nails at 3 to 4 feet centers with the
staples placed along the seams and in between the nail centers. Once you know how many
rolls of material youll need, you can calculate how many nails and staples
youll have to get. Your starting point should be at the start of the runway in the
middle of the runway. Start un-rolling the material tacking it down as you go. Complete
the center of the runway all the way to the end and then start the next roll moving toward
the edges. Pick a warm day as opposed to a cool one for the job. Although the material
appears to be very stable, laying it down on a warm day is better for getting a little
stretch and the wrinkles out. Overlap the edges of the rolls about 1 inch. When its
all done, paint your lines. Yes, the material accepts paint and it seems to be staying in
pretty good shape.
If you
cant have paving, this is a very good alternative. Since the material is woven,
water drains right through it to the dirt below. Unless it rains so hard that the ground
gets really soft, we can fly off the surface right after a downpour. Theres never
any standing water on our runway. Weeds dont come up unless there is a tear in the
fabric. This material is also very easy on our planes. Coming in for a belly landing (damn
those retracts) is no big deal because the material doesnt hurt the plane.

knowledge and research.
