Brushless Speed Controllers
Comparison Table
e
January 2004 Award
With few compatibility issues with ESC - Motor combinations, a table
should help decide which ESC BEC can work with which motor, as well as what
do they actually offer..
The ESC tested bellow were selected as generally used by the R/C Electric
community. These companies offer proven good services as
well as serious hardware.
Further tests, coming later, will include motor efficiency and throttle linearity.

| Motor/Speed controllers compatibilities |
One of the critical moment for any flying machine, is when motor
OFF, the behavior of the Speed controller to turn back the motor ON. How smooth,
how fast, any vibration, does it even work ?
This is what the table below is about as there is nothing worse
than coming for landing, motor OFF, and then needing to turn ON the motor at the
last point, and having this step not working as it should.
-
The RED
areas are simply not working so unless you really want
this configuration for specific reasons, it is highly not recommended to use
it.
-
The Brown
areas have some issues, but it could be considered not
blocking ones. Still, this is not a normal behavior
-
The Greed
areas are for complete normal operations

IMPORTANT Note: Some
older versions of some of the ESC BEC above did not work well, at all.
When you purchase a new Speed controller, make sure it is the latest
version.

- Five to ten cells with four micro servos
- Up to twelve cells with three micro servos
- Sixteen cells MAX (with BEC disabled)
- Dynamic braking ensures folding props fold promptly
- BEC (3A) provides power to receiver and servos -
eliminates separate receiver battery
- User Programmable Features:
Low-voltage cutoff
Over-current Protection
Many different Brake Type

Timing Advance
Cutoff Type
Soft Start ramp up
Switching Frequency
- Runs motor in forward OR reverse
- Auto Motor Cutoff with Reset
- Safe power on arming program ensures motor will not
accidentally turn on
- Low torque soft start prevents damage to fragile
gearboxes
- Auto shut down when signal is lost or radio interference
becomes severe
|
- No On/Off Switch
- Old hardware/software does not handle well AXI motors. New version
is fine.
- Sometimes, very rarely, on startup, would not start the motor. Needs
to unplug battery, replug it, and it works then fine
- With some JR and Royal EVO radios, Does not work with standard max
throttle. Response from Castle Creations on this
" it has a feature that detects anything higher than about a
2.25-2.3ms pulse as invalid, and will shut down as a safety feature.
We've only seen it come into play on radios capable of 130%+ ATV/EPA -
(JR computer, and now Royal Evo). we may bump that up slightly at some
point, but it is easily fixed on the Tx as you've found out. Glad
you're seeing one working like they are really supposed to!"

These ESC BEC can certainly be found at many other Hobby shops.
Checking prices at other shops could bring better deals but these 3 shops above
have proven to be reliable.

This review started with ESC BEC, which did not deliver what
each company flag ship ESC BEC could and therefore, few issues were risen. Then,
trying the latest from each company, all the problems went away, so it was not
on who had less problems than the other, but really who offers more than the
others.
Note that when a Speed Controller does not work, before thinking
it is the Speed Controller's fault:
-
Read the User Manual again
-
Make sure to check the wires, soldering, connections,
general setup, motor,
-
Is the battery fully loaded, working ?
-
Verify also how you programmed the ESC BEC. Eventually, just
to make sure, reprogram it.
Ask on the Ezone then, as chances are someone will be able to
help you identify the problem.
So who is the best ?
Difficult to choose as most presented in this list deliver
extremely well. Still, few details can help to differentiate:
Not Recommended ESC BEC
None. All the latest ESC BEC, with their latest
Hardware/Software updates worked fine with ALL Motors.
Recommended ESC BEC
So here is the final ranking. Note that these ESC BEC work
with any ESC - Motor combination test done, and they work well. Other brands may
be cheaper, or not, but experience showed that you never know if what works with
your motor setup today, will work with a different one so I would recommend
these 3 companies, as a serious choice. Not only you will be safe as they will
deliver, but they are at the top of the league for many aspects.

1st
Place

Castle Creation
Phoenix 45 |

|
| Castle Creations Latest Phoenix 45,
is smaller than the older version, offers fantastic levels of programming
and performed well in all the tests done. It does have a problem with some
JR radios and Multiplex Royal EVO (see comment in the Phoenix test
section), on the throttle management, but it is easily fixable. It does
not have a On/Off switch which is sometimes very useful. Still, this Speed
controller earns 1st place with flying colors. Note that Castle Creations
Customer Services is outstanding as well. |
| JETI Hacker Master is a jewel. Extremely smooth on the
motors, lot's of smart and powerful programming options. It could have been
better than the Castle Creations, but what I think makes it second is the
fact that Castle Creations has more programming options. Also, the fact that
you need to purchase a different ESC BEC for a heli, if you had one for a
plane, is an additional expense. Still, this is a extremely high standard
ESC BEC and if you intend to use it only on planes, and the programming
options are enough for you, then this is an excellent choice. As Castle
Creations, JETI Customer Services is excellent. Not as easy as Castle Creations
since there is no Ezone Representation, but still excellent. |

Kontronik
SMILE 40-6-12
C6 software version |

|
| Kontronik (with new software) is very reliable but does not
have much flexibility in programming modes. Still, it performed extremely well on all tests,
and proposes Heli , Planes, car, boat modes with for some mode, sub-modes, by programming. Customer Services is good,
with an Ezone representation. |
And then:
-
JETI Advanced. Also very reliable, worked on all motors
smoothly, but same comment as the Hacker Master, it has less programming
options as the Castle Creations models, which makes it not as versatile.
-
JETI old version. Old but still very good at all motor
tests. In general, it is important to note that JETI products are extremely
reliable, for all their lines of products.
