Hacker Model produces several high-quality foam aircraft, including
this Edge 540 V3 Toxic ARF. This EPP flat foam model really delivers in both
quality and performance. Flat foamies have been around for years, but even the
veteran indoor pilot is sure to enjoy this model.
The Edge 540 V3 Toxic ARF is constructed of EPP foam that is heavily
reinforced with carbon-fiber rod. The nice thing about the use of EPP is that you
can use standard CA and don’t have to worry about “foam-safe” glues that you
would need for Depron.
The hardware package is extensive and includes carbon of many lengths and
shapes; control horns; quick connects; long servo arms; carbon-fiber rod landing
gear, with skids that act as wheels; and a G- 10 motor mount.
This plane is semi-fragile and features some more-advanced methods to
create a rigid airframe. Despite this, I would say that most intermediate builders
could tackle this project and produce a model they could be proud of. Flight
characteristics are phenomenal, but the plane’s aerobatic nature will require an
The first thing I noticed when taking the Edge
540 V3 Toxic ARF out of the box is that all
surfaces are prehinged. There are V-shaped
grooves cut along the hinge lines, which allow
the EPP to act as its own hinge. A little folding
loosens these up nicely and really speeds up the
Obviously, being an indoor airframe requires
extreme light weight. For this reason, there are
no flaps, retracts, etc., to weigh things down—
just the essential four controls and away we go.
Along the same lines, there are no fiberglass
parts (other than the G- 10 motor mount). Even
the wheel pants are a simple silhouette cut from
3mm EPP foam to keep things light.
Another thing that really jumps out is the
color scheme on this model. Everything is
The FlightPower FP25 3S 350mAh battery provides plenty of power. The included precut control horns fit perfectly and give plenty of control authority.
the rudder authority is awesome. i was able to
perform knife-edge figure-8s below 25 feet with
zero coupling programmed in the radio.
