The Kontronik Smile series has a fairly mild timing
setting which makes it best for 2 pole motors, Hackers and
Kontoniks. I have used it on Aveox motors and smaller Mega's
with good results as well. Just to review, there are 5 modes
you can program your ESC to as listed below, in the case of
a helicopter we want mode 4 or governor mode.
- Mode 1 is airplane mode which selects the full
throttle position each time you connect the
pack.
- Mode 2 is glider mode, brake enabled and full
throttle position set in the programming
routine.
- Mode 3 is airplane/boat mode, brake disabled and full
throttle position set in the programming
routine.
- Mode 4 is heli mode, brake disabled, active RPM
control (governor mode) and full throttle position set in
the programming routine.
- Mode 5 is competition mode, brake enabled as hard as
possible with all safeties off and timing advanced for
max power.
Setup Procedures:
- Preliminaries - set your normal throttle curve to
0-50-100, idle 1 to 75-75-75 and idle 2 to 80-80-80. Your
heli should be fully flight ready. Programming the ESC on
the bench with the blades off or pinion off accomplishes
nothing.
- Turn on the Tx, set to the normal throttle
curve.
- Plug in the battery, the motor should beep to
indicate it is armed.
- If it doesn't beep with the throttle fully down check
2 things - throttle channel needs to be reversed if it is
a Futaba Tx. Also, expand the throttle ATV value to about
110%. Either or both of those should get it to beep
indicating its armed.
- On the label side of the ESC there is a pictogram of
a hand with a finger pointing and it says "taster". The
finger is pointing to a bump / button under the
heatshrink. Press that button and it will go Beep-Beep!
indicating it is in programming mode.
- Each of the following beep or series of beeps
indicates the mode:
- Now the ESC will beep 1 time (mode 1) then be
silent for 5 seconds or so
- It will beep 2 times (mode 2) then be silent for 5
seconds or so
- It will beep 3 times (mode 3) then be silent for 5
seconds or so
- It will beep 4 times (mode 4) then be silent for 5
seconds or so
- This is mode 4 which is what you want, once you hear
the 4 beeps move the throttle to full - don't worry, the
motor will not start.
- Wait a few seconds and you will hear 3 beeps, move
the throttle to off.
- After a bit you will hear 4 beeps indicating it is
set to mode 4, if you had chosen mode3 it would beep 3
times.
- Disconnect the battery.
Now, your ESC is programmed to governor mode but there is
one more step, the ESC needs to learn the characteristics of
the motor.
- Reconnect the battery, pull the throttle all the way
down until you hear the arming beeps.
- Slowly raise the collective to about 40%, the motor
will slowly spool up and begin going up and down in RPM
for a while. You are at less than hover pitch so the heli
won't takeoff. After 10 seconds or so the RPM will
stabilize. Shut it down, disconnect the battery.
- ESC is now fully programmed and
calibrated.
To fly connect the battery, arm the ESC then either spool
up in normal and turn on idle 1 or just hit the idle 1
switch, the ESC will spool up the motor very slowly until it
reaches the RPM for 75% and you can fly. If 75 is to slow
try idle 2 at 80. Adjust the idle 1 and 2 values to suit. If
the headspeed is too low, increase the pinion count.
There are lot's of misinterpretations of the Kontronik
instructions floating around on the web. There is no need to
change your pitch curves for a flat zero degrees, step 2
does NOT require you to get to full throttle. Only the first
step needs 100% throttle and the motor does not run in that
portion of the procedure. You definitely should program the
ESC with the blades on, it needs the load on the mechanics
when it calibrates itself to the motor in the second
step.
