E-flite Diamante 5e ARF Assembly Manual
Flying the Diamante 25e
You will find the Diamante 25e to be a solid, honest-flying
model. It is capable of handling all kinds of weather.
Ensure your CG is set according to the manual and power up
the aircraft. Move your throttle trim up slowly until the motor
just begins to spin. This will be your flight idle that will help to
establish a longer glide path and tends to make landings easier.
Before taxiing out to the runway, double-check all controls are
working in the correct direction and functioning properly. Taxi
out to the runway and line up into the wind. You will find the
rudder very effective; on the ground tracking is very predictable.
Apply power smoothly and begin the takeoff roll. Correct with
rudder as necessary and apply up elevator slowly until the
model lifts off. Once in the air, trim the model for level flight.
For optimum aerobatic performance, trim for a slight dive, both
upright and inverted. Center of Gravity will affect the feel of
the natural feel of this model and is why a large battery tray
was designed into the aircraft to allow variations of the Center
of Gravity simply by relocating the battery. Each pilot will have
a personal preference of their optimum Center of Gravity,
but for first flights we would recommend using the forward
recommendation. Included in this kit was an aerobatic trimming
article written by 7-time TOC competitor Peter Goldsmith. By
following his detailed trimming information you can have the
Diamante performing perfect aerobatic maneuvers.
Landing the Diamante 25e is as easy as setting up on final
approach, lowering the throttle to idle and gliding in to a
soft three-point touch-down. One thing to be aware of is the
Diamante has a very efficient airfoil, so set up for the final
glide path farther out than expected to ensure you are not over-
shooting the touch-down point.
We hope you enjoy the experience of flying a pure aerobatic
performer like the Diamante 25e.
Happy landings.
Reduce Your Workload
One of my passions in life is to teach. After a long discussion
with Mike Hurley and after sharing with him how passionate
I was to share my life’s aerobatic knowledge, we decided that
a trimming article would be a great start. A properly trimmed
model can reduce your workload in an aerobatic sequence by
an enormous amount. I judged at the nationals this year and
thoroughly enjoyed the experience. I was also impressed with
the skills, especially in the lower classes, when displayed by
pilots trying to fly with a poor trim setup. I was truly amazed
how tolerant people were; in fact, it drove me crazy to watch.
I remember bouncing out of my judging chair and saying to
Mike, "Boy, I need to help these people." Hence, here I am
typing away at my exciting pace of about 80 minutes per word
<grin> in an attempt to help educate the great skill base that
exists in the US scale aerobatic scene. Like all good input, it
doesn’t come from me, but is more a summary of 25 years of
meeting people who shared their thoughts on trimming with me,
then melting them down into some kind of legible format that
most can understand.
