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.
INPUTS:
to ACT.
to 75.
to 10.
to 80.
to MIXED.
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.
