● All welding requires good welding technology,
short circuit between the element or the wire
should be avoided at any time.
● Please ensure all solder joints are insulated
with heat shrink where necessary.
● Please double-check the polarity is correct
before power up.
● VBAT is battery output, make sure your device
operating voltage is matched if you want to use
VBAT.
● ISA port can be connect to the port on F.C
for current meter.

1. Rampup power:
Rampup power can be set to relative values from 3% to 150%. This i s the maxim um power th at is allow ed when ram ping up at lo w rpms and du ring star tup. For
low rpms, the maximum power to the motor is limited, in o rder to fac ilitate d etectio n of low B EMF voltages.
Rampup power also affects bidirectional operation, as the paramete r is used to li mit the pow er applie d during di rection r eversal .
During startup, the actual applied power depends on thrott le input, a nd can be low er than the m aximum le vel set by th e rampup po wer param eter, but the
minimum level is a quarter of the maximum level.
2. Motor timing:
Motor timing can be set between approximately 1° and approxi mately 31 ° in approx imately 1 ° increme nts (actu al accura te values here are 15/16ths of a degree).
Typically a medium setting will work fine, but if the motor stut ters it can b e benefici al to incre ase timin g. Some mot ors with hi gh inductance can have a very long
commutation demagnetization time. This can result in m otor stop o r stutter u pon quick t hrottle i ncrease , particularly when running at a low rpm. Setting timing
to high will allow more time for demagnetization, and often he lps.
3. PW M frequency:
Motor pwm frequency can be programmed between 16kHz and 48kH z. Higher p wm freque ncy can run m otors smo other. Pro grammab le frequency also allows for
moving of small but potentially disturbing humps in the thro ttle resp onse. All E SCs have these bumps, with BLH eli_32 th ey can be mov ed in the rpm range, to a
place where the system has low sensitivity to them.
4. Demag compensation:
Demag compensation is a feature to protect from mot or stalls c aused by lo ng windin g demagne tizatio n time afte r commutation. The typical symptom is motor
stop or stutter upon quick throttle increase, par ticular ly when run ning at a low r pm. As mentioned above, setting high commutation timing normally helps, but
at the cost of efficiency. Generally, a higher valu e of the comp ensatio n paramet er gives be tter prot ection. If demag compensation is set too high, maximum power
can be somewhat reduced.
5. Maximum Acceleration:
Maximum acceleration can be set between 0.1%/ms a nd 25.5%/ ms. It can al so be set to ma ximum, in w hich case a ccelera tion is not limited. Limiting acceleration
is primarily intended as a backup parameter that can be used in ca ses where t oo hard acc elerati on gives de syncs. Wh en settin g to e.g. 10%/ms, it means that the
power applied to the motor is not allowed to increase by more than 1 0% per mill isecond .
6. Direction:
Rotation direction can be set to fwd/rev/bidire ctional f wd/bidi rection al rev. In b idirect ional mod e, center t hrottle is zero and above is fwd rotation and below is
reverse rotation. When bidirectional operation is sele cted, thr ottle cal ibratio n is disabl ed.
7. Beep strength: Set s the stren gth of beeps under normal operation.
8. Beacon strength:
Sets the strength of beeps when beeping beacon beeps. The E SC will st art beeping beacon beeps if the throttle signal has been zero for a giventime. Note that
setting a high beacon strength can cause hot motors or ESC s!
9. Beacon delay: Beacon delay sets the delay before beacon beeping starts.
10.Throttle Cal Enable: If disabled, throttle calibration is disabled.
11. Min throttle, max throttle and center throttle:
These settings set the throttle range of the E SC. Center throttle is only used for bidirectional operation. The values given for these settings are for a normal
1000us to 2000us input signal, and for the other input signals , the value s must be sca led. For Ds hot input s ignal, th ese settings have no effect.
12.Thermal protection:
Thermal protection can be enabled or disabled. And the temperature t hreshol d can be prog rammed The progr ammable t hreshol d is primar ily meant as a support
for hardware manufacturers to use, as different ha rdwares c an have diff erent tol erances o n the max tem peratur es of the various components used.
13.Low R P M power protect:
Power limiting for low RP Ms c an be enabl ed or disab led. Disa bling it ca n be necess ary in order to achieve full power on some low kV motors running on a low
supply voltage. However, disabling it increases the risk of s ync loss, w ith the pos sibilit y of toasti ng motor or ES C.
14.Low Voltage Protection:
Low voltage protection can be set between 2.5V and 4.0V per lipo c ell. Or it ca n be disabl ed. When en abled, it w ill limit p ower appl ied to the motor if the battery
voltage drops below the programmed threshold. This feat ure is prim arily intended for fixed wing crafts.
15.Brake on stop:
Brake on stop can be set between 1% and 100%, or disabled. When not di sabled, b rake will b e applied w hen throt tle is zero . For nonze ro throttle, this setting
has no effect.
16.LE D Control: LE Ds can be controlled on E SCs that support it.
17.Non Damped Mode:OFF- Damped light is available ; ON- No Damped light。

● ESC will automatically detect the input throttle signals every time as soon as it powered on, and then execute the corresponding signal-receiving
mode.
● User need to calibrate the throttle range when starting to use a new ESC or another transmitter. When the input signal is Dshot, throttle calibration
is disabled.
● BLHeli-32 firmware, please don't flash any other firmware except “Flycolor_X_Cross_B L_32”.
● Observe polarity at all times. Check and double check before applying power.
● Power off before unplugging ,plugging in or making any connections.
● Please do not exceed the current range.
● Do everything you can to prevent vibrations.
● Please contact Flycolor sales or technical support for more information.
