I have just installed the new type Elmod 4 CH Prop system into my HL Tiger. This is the latest Think Tank module, with the new sound blaster III stacked on the top.

The problem I have is that I have no response to any of the controls at the Transmitter.

I am using a brand new Futaba 4YF-FM40 4-CHANNEL 40 MHZ Transmitter with a Futaba RX R136F 6CH. receiver. I checked with elmod before purchasing it to make sure it was compatible with their system.

This is what has happened.

1 Switched on.
2 Green LED on, Red LED flashing on TT Module
3 Removed Jumper 6, Tracks/Chains move forward, the right Track/Chain quicker than the left, Green LED is on and the Red LED is still flashing.
4 Switched off
5 I attached the Receiver cable to the TT Module and its wires to the receiver.

Red/Black - power supply for the receiver (BEC)
Brown cable - Channel 1
Orange cable- Channel 2
Yellow cable - Channel 3
Green cable - Channel 4

Blue cable - channel 5 left unconnected.
Violet cable - channel 6 left unconnected

6 Connected the 8 pin Turret plug.
7 connected the Sound blaster III Volume control and speaker cables
8 Switched on
9 Green LED on, Red LED still flashing on TT Module. Solid Red LED on Sound blaster III Module
10 Absolutely no control functions working at the Transmitter.

As stated in the manual, I have connected a servo to the receiver ( This was connected to each of the 4 channels in turn) and this worked perfectly from the transmitter.

I am left with these conclusions. The Error - Red LED is blinking continuously, no valid signal from the receiver ?

Is the Transmitter and receiver compatible with the ELMOD System?

Is there a fault on the Think Tank Module and possibly the Sound Blaster III Module ?

These are the only two answers I can come up with.

I tried another servo (Futaba) with power from the Think Tank Module black/red wire through the receiver and it worked fine on all 4 channels. Its got to be a problem with the board not recognizing the Transmitter and receiver. Either a faulty board or non compatibility with the Radio gear.


Has anybody out there had a problem with the compatibility of the Futaba 4YF-FM40 4-CHANNEL 40 MHZ Transmitter and a Futaba RX R136F 6CH. receiver, when trying to use it with the elmod system ?

So, is it a faulty Elmod Think Tank module/ sound blaster III module or is the Radio gear the problem. ?


Thanks.
