The author’s preferred mount for the RunCam 2 includes the camera cradle, a GoPro tripod adapter, a
disc of foam rubber, and a 1/4-20 nylon bolt with plastic washers.
A properly positioned wingtip camera can frame the entire airplane in the shot.
the wingtip and another at roughly
midspan. I then mirror those holes on
the opposite wing. This gives me a lot of
flexibility for different shooting angles.
Make sure that there are no servo wires
or internal spars in the way before you
start drilling with the brass tube.
Whenever you use a wing-mounted
camera, you’ll also need to have a
counterbalance on the opposite wing.
The easiest solution is to use a second
camera. If you only have one camera,
however, you can simply use an
I made a counterbalance by gluing
lead weights to a small piece of scrap
1/8-inch plywood with a 1/4-20 blind nut.
The ballast assembly weighs the same
as a mounted RunCam 2 and uses the
same 1/4-20 nylon bolts for attachment.
Fuselage-mounted cameras can
sometimes be trickier. That’s because
flat, easily accessible mounting spots are
rare. Before drilling any mounting holes,
you’ll want to make sure that you can
get the 1/4-20 bolt into place and have
access to tighten it. Areas near battery
hatches are usually good spots. You can
actually mount a camera directly to the
hatch, but make sure that the hatch is
Many fuselages have a rounded top
surface, which can make it tough to
secure the flat-bottomed tripod mount.
Sometimes replacing the plastic washer
with an extra layer of foam rubber is
sufficient to stabilize the mount. In
more extreme cases, I’ll make a hasty
arch-shaped adapter out of scrap foam.
The inside of the arch approximates the
curvature of the fuselage while the top
side of the arch is flat. Again, placing
foam rubber between the fuselage and
arch is helpful.
I’ve also used a variant of foam arches
in areas where it isn’t feasible to run
a mounting bolt through the fuselage,
such as the rear of a glider. I epoxy a
short 1/4-20 bolt to the arch. This holds
the camera to the arch. I then attach
the arch to the airframe with rubber
bands, hook-and-loop straps, and/or
tape—whatever makes sense for each
As with wing-mounted cameras,
fuselage cameras often upset the
airplane’s balance. Sometimes, there is
sufficient flexibility in battery placement
to achieve a center of gravity (CG)
location. Other times, you’ll have to
add weight or another camera to regain
the CG. If you need to add more than
an ounce or two of ballast, you should
reconsider your camera location.
Some of my airplanes don’t seem to
fly any differently, even when carrying
two cameras. Others have a significantly
