Great Planes Profile 38 - GPMA0487 - Manual (Page 46)

If you installed two .15-size engines on your plane, and one
engine quits, the plane will not be able to maintain altitude
on one engine. Be careful to maintain your airspeed so that
the wing does not stall. Decide where you are going to land
and don’t try to stretch the landing. It is better to land with a
little extra speed than to stall the plane on the landing
approach.
To initiate a landing approach, lower the throttle while on the
downwind leg. Allow the nose of the model to pitch
downward to gradually bleed off altitude. Continue to lose
altitude, but maintain airspeed by keeping the nose down as
you turn onto the crosswind leg. Make your final turn toward
the runway (into the wind) keeping the nose down to
maintain airspeed and control. Level the attitude when the
model reaches the runway threshold, modulating the throttle
as necessary to maintain your glide path and airspeed. If
you are going to overshoot, smoothly advance the throttle
(always ready on the right rudder to counteract torque) and
climb out to make another attempt. When you’re ready to
make your landing flare and the model is a foot or so off
the deck, smoothly increase up elevator until it gently
touches down.
One final note about flying your model, have a goal or flight
plan in mind for every flight. This can be learning a new
maneuver, improving a maneuver you already know, or
learning how the model behaves in certain conditions (such
as on high or low rates). This is not necessarily to improve
your skills
(though it is never a bad idea!), but more
importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly finding that you’ve run
out of time, altitude or airspeed. Every maneuver should be
deliberate, not impulsive. For example, if you’re going to do
a loop, check your altitude, mind the wind direction
(anticipating rudder corrections that will be required to
maintain heading), remember to throttle back at the top, and
make certain you are on the desired rates (high/low rates).
A flight plan greatly reduces the chances of crashing your
model just because of poor planning and impulsive moves.
Remember to think.
Have a ball! But always stay in control and fly in a safe
manner.
GOOD LUCK AND GREAT FLYING!
ElectriFly ™ by Great Planes Triton ™ Peak Charger
Imagine a charger so versatile it can be used with lithium-
ion and lead-acid batteries as effectively as NiCd and NiMH
cells. A unit that can peak charge tiny park flyer packs and
24V car batteries alike. A charger that can discharge as well
as charge, cycle packs from 1 to 10 times automatically,
memorize peak and average battery voltages for each cycle
– and constantly display battery capacity, voltage, current
and time as each cycle progresses. Then, imagine that the
charger, which can do all this, is about the size of a thick
paperback book, and weighs just over a pound. The
advanced computer technology in the Triton Peak Charger
makes it possible to accomplish all this and more, through
controls and menus so simple that programming is a breeze.
