For the past several years, Performance Aircraft Unlimited (PAU) has put out some of the
most scalelike 3-D airplanes available.
Not only do they look good, they also
fly extremely well. Whether you enjoy
sport flying, or down-on-the-deck 3-D,
PAU has all of the bases covered.
One of these aircraft is the 50cc to
60cc-size Edge 540T. Its striking orange
paint scheme and great scale outlines
make it a good-looking airplane. Capable
of accommodating 50 to 60cc-size
engines, the Edge 540T comes with
everything you would expect to find in a

comes with this kit includes a Du-Bro

The wing and stabilizer tubes are
carbon fiber, as is the landing gear. The
wing halves came in silver padded wing
bags—perfect for keeping the wing in
great shape when transporting it.
The airframe went together easily. I
always start by putting my airplanes on
their landing gear, and I’ve found that
this helps protect the airframe during
the building process.
My engine of choice was a Desert
Aircraft DA-50R with a Pitts-style
muffler. Three-inch stand-off mounts
were used to get the spinner right in
front of the cowl with a small gap
between it and the spinner backplate.
The Edge 540T also has a built-in
premade pipe tunnel for those who
want to use a tuned pipe. I used high-torque digital servos all around, with
11/2-inch SWB MFG servo arms and a
Futaba R2008SB receiver to guide it.
All of the control surfaces are
predrilled, with the Robart-style hinges
in place, but they are not glued in. I
prefer this because there is nothing more
frustrating than having to fix a crooked
hinge that wasn’t glued in correctly at

I checked the fit of all of the hinges
before gluing them in. The hinges were
