E-flite Super Cub 25e ARF Assembly Manual

Range Test your Radio

Before each flying session, and especially with a new 

model, it is important to perform a range check. It 

is helpful to have another person available to assist 

during the range check. If you are using a Spektrum 

transmitter, please refer to your transmitter’s manual for 

detailed instructions on the range check process.

  1. With the model resting on the ground, stand 30 

paces (approximately 90 feet) away from the model.

  2. Face the model with the transmitter in your 

normal flying position. Be sure the throttle is in the 

full down position and plug the flight battery into 

the speed control.

  3. As you move the controls, watch to be sure the 

airplane’s motor and controls operate smoothly. 

You should have total control of the model at 30 

paces (90 feet).

  4. If control issues exist, call the appropriate 

Horizon Product Support office (see addresses listed 

in the Warranty Services section of this manual) or 

go to 

horizonhobby.com

 to find a local Spektrum 

distributor in your country for service if using a 

Spektrum radio system.

Flying your Model

Okay, it’s time for the moment of truth. Now that you 

have your Super Cub at the field and put together, take 

the opportunity to check over everything one more time 

to ensure that all is in order. Verify control direction, 

battery level, CG and range check your model. After 

everything checks out, the only thing left to do is 

violate some air molecules.

Set your throttle trim to a low idle; this will be your 

flight idle. Taxi out to the runway and line up with the 

centerline. Smoothly advance the throttle and maintain 

directional control with the rudder. The Super Cub is 

a very light airplane and has a very large wing, so it 

doesn’t take much airspeed to get airborne. If you hold 

a little up elevator, the airplane will be off in about 15 

feet. If you apply a little down pressure to raise the 

tail, you’ll have a longer takeoff run. Once you are 

airborne, establish a gentle climb angle and make a 

climbing turn to parallel yourself with the runway.

Once at altitude, you’ll find yourself cruising around 

at half throttle. Trim the airplane out and get the feel 

for how it flies. Cubs are inherently very gentle, so 

you’ll have no issues with maintaining control or 

getting behind the airplane. After you have the feel 

for it, try your hand at a few basic maneuvers—loops, 

rolls, wingovers, spins, etc. The airplane will perform 

these with great ease. Many full scale Cubs fly these 

barnstorming-type maneuvers, so coupled with the 

detail of this Platinum Series design, you’ll have a hard 

time distinguishing your airplane from the real one!

Unfortunately, all good things must come to an end 

and your flight battery is the malevolent dictator of this 

directive. Before you try and set up for a landing, pull 

the power back and try some slow flight. Extend the 

flaps and get used to how the airplane handles with 

flaps extended. They have quite a bit of area, so they 

will induce a lot of drag when you have them fully 

extended. It’s best in a landing configuration to not try 

and drag the airplane in with flaps; you need to aim it 

at the ground and fly it in.

Set up on a downwind leg and reduce power. When 

you are abeam your touchdown point, add the first 

notch of flaps. Continue your descent into your base 

leg and onto final. Gauge your decent rate and let that 

be your judge whether or not to fully extend your flaps. 

When you are over the threshold, begin to reduce 

power to idle. When you get close to the ground, 

round out your descent and flare. You should touch 

down gently. Once back on the ground, maintain 

directional control with the rudder. 

That’s it! You’ve just flown your Platinum Series Super 

Cub from E-flite. We wish you many more successful 

and enjoyable flights with it in the future!
