.
Flight This plane can fly f
a
st f
or about 6 min

.The air
plane is f
ast b
ut predictab
le
.
Get used to the pl
ane at lo
w
rates bef
ore s
witching to high r
ates as the roll and pitch r
ates will become e
xtremely quic
k on high r
ates
.
Flight times will increase if throttle management is pr
acticed.
The Mini Delta EP can maintain altitude at 1/3 throttle and it c
an fly
most maneuv
ers at ½.
The Mini Delta EP is still stab
le and predictab
le at slo
w speeds and it also allo
ws the pilot more time to
think
about its reactions
.
The Mini Delta EP is capab
le of loops and rolls
, in
v
e
rted flight and an
y other maneuv
er that does not require r

,
it can also perf
or
m some stalling maneuv
ers lik

.
Landing T
o
initiate a landing approach, lo
w
er the throttle and let the air
plane lose some altitude
.
When the model is 2-3 f
e
et [60-90 cm
] from
the g
round, apply up ele
v
ator to b
leed off speed and land while maintaining the same heading.
