(13) Battery F/S voltage setting [default: 3.8V] [ranges: 3.5V ~ 7.5V ]
This parameter sets the battery fail safe and low battery alarm voltage. Set the proper voltage by
the battery type. The battery characteristics are different depending on cell type/chemistry. The
voltage setting is changed by pushing DATA+ or – key. Suggested setting voltages are as follows.
• 4 cells NiCd or NiMH (Normal: 4.8v) = 3.8 v
• 2 cells LiFe (Normal: 6.6 v) = 6.0 ~ 6.2 v
• 2 cells LiPo (Normal: 7.4 v) = 7.2 ~ 7.4 v
(14) Low revolution setting [default: 1000 rpm ]
This parameter sets the minimum revolution setting ranges. The setting can go as low as 700 rpm
to accommodate large gasoline powered models.
(15) Governor data reset
This parameter resets also the governor parameters to default settings. The “Exec.??” is displayed
by pushing data + or – key for confirmation. Pushing data+ or -key again completes the reset pro-
cess, displays “-Exec.-”, and returns to the start display. By pushing mode+ or – key during confir-
mation display, the reset process is aborted.
(10) Governor ON revolution setting [default: 60%] [ranges: 50% ~ 90%]
This parameter tells the governor at what percentage of the set rpm it is to become active. The
default value is 60 %. In this case, the governor will not engage until the engine rpm reaches 60
% of the set rpm. If you feel that the time for governor engagement is too slow, decrease the value
to 50 ~ 55%. The starting time will be faster.
(11) Low limit at hovering [default: 25%] [ranges: 0% ~ 80%]
This parameter sets the governed throttle low limit during hovering rpm to avoid too lean a fuel
mixture caused when the governor places the throttle in the typically lean mixture range of about
25%. By pushing data+ or – key, the value is changed.
(12) Low limit at idle up [default: 45%] [ranges: 10% ~ 80%]
This parameter sets the governed throttle low limit during idle up rpm to avoid to avoid the same
excessively lean fuel mixture described for (11), above. By pushing data+ or – key, the value is
changed. Low limit at idle up is also useful to tune out overspeed or underspeed when the rotor-
head is depitched in certain aerobatic maneuvers.
