Heli Mode Instruction for HiFei KII&GII ESC

ManualsBrandsTurnigy ManualsBoatsUSB Linker for Aquastar, Super Brain & Fatboy ESC

Dear Customers, HiFei TEAM special added the Heli Mode options in the last HiFei

V4.11 software, so far it is just available with the series of HiFei KII&GII. The Heli

Mode options will make it easy to compatible your helicopter and maximize your

helicopter’s performance.

Please Note: Heli Mode will be enable only when the Governor High/Low is

selected.

Spool Up Rate

It indicates the startup spool up rate, the default setting is Level 3, higher level numbers

means to approach the head speed faster.

Governor Gain

The default setting is grade 9, the higher grade number means the higher gain.

Head Speed Change Rate

The default setting is standard, this setting indicates the change rate between 2 different

head speed switching (for example, throttle curve switch up from Normal to Idle1 or Idle1

to Idle2 ,vice versa).

The "Head Speed Change Rate" value also determines the speed at which the head

recovers.

ESC output L.Limit (ESC output Low Limit) The default setting is ‘middle’, it can be understood as a low limit that ESC output the power to motor, also you can consider it as the car idle. In hard 3D fly it will be efficient to avoid lost power momentarily. If you just fly in hover, we suggest to program it to ’ the lowest’.

Throttle Calculator It is a calculator to help you calculation the throttle curve according to your desired HS, Gear rate and motor poles. Please see the following screenshot: Furthermore, fill out the battery voltage and motor KV can help you find out the ESC power output match with the pre-set head speed, HiFei recommends for optimum the ESC output to motor about 80% power, it ensure the ESC has enough reserve to compensate the battery voltage decreasing and load changing.

Incorrect gear rate/motor KV probably results the ESC Output haven’t enough reserve to compensate battery voltage decreasing and load change, in the case there is a tab pop out to indicate ‘Head Speed Out of Control Range’. Generally you can Inc/Dec the tooth of motor pinion or Inc/Dec the Desired Head Speed to get the best match results.
