7 Proper Range Checking
We recommend this version of proper range checking as written By JR Propo.
Place model perpendicular.
Program up-elevator Fail Safe.
Remove antenna.
Hold transmitter arms length.
Walk backwards until elevator deflects
STOP
and mark position and measure,
carefully count how many paces out you went.
Re-program Fail Safe for engine to idle.
Perform exact same test with motor running at 1/2 throttle. When engine goes to idle
STOP
and mark position, and carefully count how many paces you went.
If you lost more than 20% with the motor running investigate and retest. JR Team
Members like to see minimums of:
o
Engine off 175 Feet, 60 paces, 55 m.
o
Engine running 150 feet, 50 paces, 50 m.
DON’T FORGET AFTER THE ABOVE RANGE CHECK TO RESET YOUR
FAILSAFE TO “ENGINE OFF” THROTTLE DOWN TRIM DOWN!
The following procedure describes how to properly set-up the "failsafe"
feature on a JR
12X transmitter:
STEP ACTIVITY
1. Gear lever in the down position
2. Using code 12, set the throttle travel to
100% "high" and 100% "low."
3. Bind the system per JR manual instructions. Note: Throttle stick and trim must be at a
minimum before you bind it.
4. "Teach RC" to the ECU per Jet Central manual pages xxx through xxx.
STEP TESTING AND VERIFYING THE FAILSAFE
1 Start the engine. Set the power to any setting above idle.
2 Turn off the transmitter but leave the receiver on and engine running.
Verify that the engine power goes to idle after 0.5s and shutdown after 2s.
If signal from TX is regained during these 2s, power will return to normal
