Well, my Heng Long Abrams is up and running and doing fantastic with the DBRC 4 and Benedini. I am glad now that I didn't use the el mod in it. I turned on the El Mod Abrams the other day. The sound was great however the flash had stopped functioning, I checked connections and ended up ordering a new flash. I plugged in the replacement and turned it on, The flash works, however no sound, I checked the sound blaster (El Mod sound unit) and it wasn't plugged in well. I made sure connections all made. Turned it on and Abrams track gone. Evidently the micro sd card in it erased the Abrams sound file and all I get is a startup of a tiger not the Abrams, then silence. My guess is there is a remnant of another sound file on the card. So now I have flash and no sound. Anyone know where I can get the Abrams sound file and how to download it? Thanks.
