Hi again
So Ibought the little
amplifire, wow what a differens! The sound is now crystal clear, and twice as loud as before. I also bought a new speaker, a little bigger than the standard HLspeaker. I used the smoke units power output on the RX18.
This is a great little upgrade, and a good way to get better and louder sound in your Heng Long tank!
Here are some pictures. As you can see the amp fits perfectly in the HLspeaker slot.
