Question How to enter ESC's program mode?

I am waiting to get into the BLC-40's programming mode in my new 325S.

I have a DX8 transmitter, throttle curve set 0-100%. The GT5.1 is in a 325S and currently has one DSMX Carbon remote satellite receiver.

Failsafe in the GT5 is set to 0/off.

I turn on the TX, set the throttle to full stick, then plug in the battery to the ESC, it initializes, but doesn't go into the program mode. When I lower the throttle and then bring it back up again, the motor starts to spool up.

Any trick to this?

yes and no lol...

the guy got it figured out by adjusting his end points, but he didn't say how or what he ended up with =\

Mine are 100/100 in the TX.

Your throttle curve is linear and you can't access it still? Here's some instructions I found elsewhere to just paste here. (Think this is from manual?).. Make sure you are working safely with a gear missing from the drive train

The following processes will explain the throttle calibration
and the setting of ESC.
1.As a safety precaution, we recommend disengaging the
pinion gear from the main gear during this procedure.
2.Also review the FUNCTION MODE CHART and select which
modes you wish to use since the setting procedure immedi
ately follows the calibration procedure.
3.Turn on the transmitter and put the throttle stick at full
throttle position.
4.Turn on the receiver if no BEC.
5.Connect the battery and the ESC.
6.You will hear 6 tones ( ) from the ESC, which
means the full throttle position has been calibrated.
7.Move the throttle stick to the idle position (lowest
position). You will hear 4 tones ( ), which
means the idle throttle position has been calibrated and
now the ESC will enter the setting mode.
8.While in the setting mode you will hear combinations of
sounds, which represent various functions. Each sound
consists of a long tone and a short tone. The long tone
represents which function is being set, and the short tone
represents the option mode for that particular function.
You can check the FUNCTION MODE CHART to get the
correlation for the difference function mode and the
combination sounds.
9.Shortly after the idle position has been calibrated you will
start to hear these setting tones. If you wish to select the
setting of the mode then move the throttle stick to full
throttle position and wait for the confirmation sound
( )means this mode you select has already been
set. After that, move the stick to the idle position and
waiting for the next function mode setting. If you do not
wish to select this setting, leave the throttle stick in the
idle position and wait for the subsequent setting mode.
10.The setting sequence for these 5 main functions will be
#8211;(1) Battery Protection (2) Motor Timing (3) Brake Mode
(4) Throttle Sensitivity (5) Flying Mode.
11.After setting is complete, please turn the power off by
disconnecting the battery from the ESC. If you only change
certain functions, the others will remain the factory

Thanks, I should have mentioned that I have the manuals and did read them several times. I'll put in a call to Steve at Hobbico on Monday.

K wish I could figure this out but I am not sure what the heck, lol I know this is the esc off the e325 which I have built/repaired but can't remember actually doing one.

Hope Tower can figure this out for you

Hobbico support suggested maxing out my DX8's throttle end points. I did this and it didn't resolve the problem. The model flies, but I have no idea whether or not the throttle is actually calibrated correctly and either way, I'd like to adjust some parameters in the ESC.

Maybe someone else can chime?

Anyone figure this out?

I worked around it by using a separate receiver.

Not sure why, but I didn't have any problem with a GT5 and programming this ESC for a friend.

my FBL unit is the GT5.1, radio is DX8.

The ESC would not go into programming mode when following the programming instructions. It would not see a 100% throttle signal on initialization. I had to hook it up to a separate receiver (AR6000) to get it to work.

Did anyone ever figure this out. I have the same issues with my DX7s and a GT5.1. If I use satellite receivers the ESC will not arm so I am stuck using a full size receiver and would much rather use the satellites. Throttle end points in the transmitter made no difference and it wont calibrate. The GT5.1 just doesn't seem to output the correct signal to the ESC. Using a full size receiver the throttle plugs in to the receiver directly and it works fine.

When I've run into this in the past (with an ar7200bx and with a walkera 2703h-d) what I do is:

1) temporarily pull the red wire from the esc throttle cable (or use a Y cable with the red wire cut on one side)
2) power up the FBL unit with an RX pack, wait for it to fully initialize
3) go to full throttle
4) power up the ESC with the flight pack. The esc should then see the signal at full and allow you to calibrate/program the esc.
5) power all down and put the red wire back and give it a try.

I have to do the same thing on my gt5.2 (v1 hardware) so I'll let you know how it goes.
