Have you ever
wondered what
a very well designed ARF
plane should be like?
Well, like this one.
The EasyStar User Manual is of the best there is. Clear,
multilingual, many illustrations, and tips. Just Perfect.
Building the plane takes very little time, a matter of one to two hours,
tops. All the parts fit together perfectly. This is Multiplex at its
best, one could say. The wings are very well-engineered. They can be
fit, just by clicking one into the other. To remove them, just pull
slightly; so convenient!
The cockpit is the same way, just push it, and it will click and be
locked. To remove it, just pull it.
It is recommend not to use Epoxy in the manual
but this is what I have used for all my Multiplex Elapor Planes for years
and it has always worked great for me, so make your own choice on this
one.
Tips:
-
Don't forget to add some tape on the bottom of
the fuselage, for protection during landings
-
For the rudder and elevator, either detach them
and re-connect them using hinges, or be sure to flex them them many
times before connecting the pushrods. This will ease their movements
and prevent a heavy on the servos.
-
Add some cyano on the screws that close part 25
(linkage connector) (Blue thread-locker works as
well, and is not as permanent)
-
When you glue the two halves of the fuselage
together, don't use too much glue. Make sure you put it on specific
areas, which you will be able to take away. If you need to open it in
the future, you will be glad you did.
-
Some people don't glue the fuselage at all.
Then they use a different way to hold it together. (like tape) This way,
if needed, they can open the fuselage easily.
-
Add some velcro tape, where the 2 wings
connect. With time, they won't "click" as well and the velcro will
ensure that they don't disconnect during a flight.
From
drj153(ezone): "I STRONGLY suggest you tell people to use Silastic
to glue in the motor!
It
holds very well but is infinitely easier to remove the motor should it
fail - as Loopy's did yesterday!
If it
had been mine, held in with epoxy, I would still be trying to get it out
without demolishing the plane!
The
Silastic took 10 seconds to remove!
"
|
| Take-off |
Absolute piece of cake. Just throw it full
throttle, against the wind.
|
| Flight behavior |
This
is a first plane trainer. All movements are slow, especially the rudder
inputs and especially at low speeds. Still, it behaves extremely well, with
absolutely no bad behaviors spotted. Stalls are straight, and easy to
recover from. Turns are smooth, without any surprises. The plane does not
know what tip stalling is. It can do loops and simple maneuvers that any 2
axis trainer can. Slow and fast speeds are both easy. It also handles windy
conditions well. The stock version flies beautifully.
On full throttle, the plane tends to climb too much, only to be stopped by a
stall. If you release the throttle, it glides perfectly so you can either
compensate manually while climbing, or by programming some mixing between
the throttle and the elevator.
|
| Landing |
No event phase. Cut
the throttle and it glides slowly towards landing, with a slight flare just
before touch-down
|
| Crash Results |
The plane is so well
designed that not only can Elapor take quite a lot of abuse, but breaking
the wings must very difficult. They can unlock under stress easily, instead
of breaking. A direct vertical hit would damage the fuselage, but again,
nothing epoxy could not fix easily.
|
| Repairing |
Elapor: so either
cyano or epoxy works great

| Other comments |
-
Replacing the battery pack is a piece of cake.
Just pull the canopy, replace the pack, replace the canopy, and go.
-
For Q1 2005, the
EasyStar won first place as the plane to purchase as a 1st plane. See
