AIL/ELE EXPERT MAP

(2) I gain <integral gain> [default: AIL 80% ELE 80%] [ranges: 0%



200%]

I gain tunes the ability of the model to maintain a given heading. Inadequate I gain results in a

change in model heading especially with aggressive collective pitch input. Excessive I gain can

result in oscillations in forward ﬂight or with cyclic input. On the ELE axis especially, excessive I gain

can create bounce.

(3) D gain <differential gain> [default: AIL 0% ELE 80%] [ranges: 0%



250%]

D gain is best used to tune the stops following cyclic commands. Inadequate D gain results in soft,

indeterminate stops possibly with a slow bounce. Excessive D gain causes harsh stops with a quick

bounce or oscillation in forward ﬂight or with cyclic input.

(7) Flip compensation [default: 0%] [ranges: 0%



100%] (Aileron expert)

This parameter sets the mixing rate of the elevator to aileron mixing. The roll axis may be aﬀected

by a pitch axis (elevator) input as manifested by the model rolling oﬀ to the left or right during ﬂips

or loops. This mixing compensates this eﬀect. The mixing amount can be adjusted individually for

both up and down elevator stick inputs.

(6) Aileron compensation [default: 0%] [ranges: 0%



100%] (Aileron expert)

This function sets the mixing rate of the pitch to aileron mixing. The roll axis may be aﬀected by

positive/negative collective pitch movement as manifested by the model rolling oﬀ either to the

left or to the right during rapid ascent or descent. This mixing compensates this eﬀect. The mixing

amount can be adjusted individually for both positive and negative collective pitch inputs.

Roll compensation [default: 0%] [ranges: 0%



100%] (Elavator expert)

This parameter sets the mixing rate of the aileron to elevator mixing. The elevator axis may be

aﬀected by the aileron input as manifested by a tendency for the model to corkscrew or otherwise

roll non-axially. This mixing compensates this effect. The mixing amount can be adjusted

individually for both left and right aileron inputs.

(5) Dead band [default: 4.0μS ] [ranges: 0μS



25.0μS]

Dead band sets the null/non-responsive range of the stick. When the center stick feeling is too

unsettled, increasing the deadband will calm that feel. Note that excessive deadband will result in

a disconnected feel of the model to small stick inputs.

(8) Data reset

This menu resets all of the aileron (elevator) gyro parameters back to the default values. Press the

data [+] key once and [Exec ??] will be shown as a conﬁrmation. Press the data [+] key again to

conﬁrm the operation and that all of the gyro parameters have been reset

(4) Head Response [default: AIL 1 ELE 1] [ranges: 1



10]

Head response tunes the rate of data flow between the flybarless controller and the servos. In

general the default values for head response should be maintained because they yield the best

response to control input. However, if certain brands of non-Futaba servos are observed to be

running excessively warm and current consumption per ﬂight is high, then higher head response

values will ease the issue. Excessively high head response values will cause unacceptable lags in

model response to control input
