So I bought a Heng Long T-72 6.0 that has an El-Mod unit in it. It was quite an untidy install, but had some really cool features, and I was hoping to learn about the settings and how to use the app for it. I downloaded it, but it never seemed to work, and eventually shower IO Error. I literally never used the app, it didn't open and recognize the unit. I eventually gave up, went to start up the tank afterward, is stated "BATTLE MODE HEAVY TANK" like always, but after that, nothing. The blue light just flashes on the board. Also, while looking it over, two wires pulled out of an unknow component, so I am trying to figure out what it is. Pretty upsetting, I just finished painting it, and was going to start to clean up the complete mess of the wiring inside the vehicle. ANY help would be greatly appreciated, trust me. Some of the features it had were super cool...I have no idea why the app never loaded/function on my laptop. Thanks in advance.

Sandy? Ren? 

I know the first thing they will ask you Martin is pics of the 2 wires. and where they connect.

So they come from the flash module, but the real problem is what happened to the ECU. It now only flashed blue continually. It is a FUSION PRO.

Ok, cancel the EL Mod emergency. The flash unit is kaput, but the unit is fine. Looks like the BEC plug on the receiver was just not seated. Works like it should. Its a FUSION PRO, Rev F.

Hi Martin - Welcome aboard!

Glad you were able to sort out your Elmod issue.

Cheers

Thanks very much. I have a flasher unit from a Tamiya Tiger II. It may work.
