Multiple-Servo Brake Mix
BRAKE-MIX
Level
LV3
Only
DEFINITIONS:
•
Brake Mix:
Used when model has separate front and rear brakes, and they must be
adjusted separately. Uses channel 2 for rear brakes/throttle, channel 3 for front brakes.
•
RATE
: Proportion of total front brake travel applied when full rear brake is applied.
•
DELAY
: Waits to brake either front or rear, allowing the other to brake first.
•
BALN
: Balance. Adjusts the proportion of front to rear braking.
•
TGP
: trigger point. At what amount of trigger the brake mixing takes effect.
•
MXMD
: Mixing mode. Front brakes respond based solely on trigger position
(
UNMIX
), or other functions’ adjustments to rear brakes, such as ABS, also effect
front brakes (
MIXED
).
AVAILABLE FOR:
N/A
ADJUSTABILITY:
•
RATE
:
0 (no front braking) to 120% (front brake servo moves 20% more than rear brake).
•
DLY
:
0 (no delay) to 100% (maximum delay, about 2 seconds); F (front) or R (rear). Either F or R MUST be 0;
may both be 0.
•
BALN
:
80 (decreased braking) -100% (no change), F or R. Either F or R must be 100%, may both be 100%.
•
TGP
:
10 (front brakes active even with small amounts of brake) – 100% (front brakes applied only when full brake given.)
•
MXMD
:
UNMIX
(front brake obeys trigger position only);
MIXED
(front brake obeys all braking mixes).
INTERACTIONS:
•
ABS, Speed Limiter, exponential, etc., all affect the rear brake; mix mode
MIXED
causes them to also affect the front.
•
Mixing is based upon total EPA of each servo. Example: Rear servo moves 60° at 100 EPA. Front servo moves 40°
at 100 EPA. Rate of 100% moves front servo full 40° when rear servo moves 60°. Rate of 120% means front servo
moves 40° times 120%, or 48°, when rear servo moves 60°.
DESIRED END RESULT:
Model brakes as rapidly as possible without negative handling effects such as squatted shocks, etc.
CAUTION:
Unmixed results in the front brake getting drastically different inputs than the rear when functions such
as ABS are used (no pulsing on front).

GOAL:
While using
LV3
, setup brake mixing for
1/5th scale offroad vehicle, with front brake
responding 75% as much as rear, with a
slight delay to allow rear brakes to respond
first, no change in balance, front brake on
only after 80% brake and front/rear both
obeying ABS mixing. (If using
LV1
or
LV2
,
first select level
LV3
, see p. 12.)
Where Next:
STEPS:
Open and select menu 1.
Select
BRAKE-MIX
.
Activate brake mixing.
Adjust rate to 75%.
Adjust front delay to 10.
Adjust trigger point to 80%.
Set to mixed mode to use all rear brake
mixing for front brakes also.
Close function and menu.

NOTE: All of these functions interact with the throttle servo as well and are all inter-related.
Adjusting any one may affect the performance of the others as described in interactions.
Adjust the throttle servo’s EPA (
EPA
): See p. 18.
Adjust overall braking speed (
TH-SPEED
): See p. 23.
Adjust throttle exponential (
TH-EXP
): See p. 20.
Adjust ABS braking (
ABS
): See p. 24.
Set up smooth acceleration off of the start and also engine cut (
AT-START
): See p. 28.
