Good question.
From what I gather, most of the complaints seem tosurround people seeking more realistic sounds rather than a dislike for the sound quality in general...at least in the newer boards. I want my speaker to drown out the grinding sound of my metal motors. It's like fingernails on a chalkboard. More bass would be lovely as well. My hope is to amplify the sounds coming from the built in amplifier in the HL board. Someone with and audio/circuitry background could probably do this for a few cents/dollars by modifying the board with new semiconductors and variable resistors, but I just don't have that knowledge. So, the only route is to purchase a speaker set with a built in amplifier.
Although Heng Long gears are not whisper quiet, you should be able to reduce the noise coming from them, so they don't sound like they are grinding. Chances are you will have to shim them with washers. Also try breaking them in using a a mild abrasive kitchen cleaner. The stuff used to clean glass cooktops is mildly abrasive and is water soluable for easy clean up when you are done. Lightly oil the bushings and apply teflon gear grease to the gears, and you should notice an improvement. You will still hear them, but they will whirr instead of grind.
I had one gear box that was extremely noisy, and I was sure it would self destruct if I left it. I had it apart about five times until I finally got it quiet.
If they sound horrible then something is misaligned and you should spend some time tweaking them. OR buy an upgraded gear box set from Asiatam or Mato
Now that was extremely helpful and great info for a newb such as myself!
I recently had a terrible issue with a motor that was making horrible noise right out of the box. But I didn't know any better and assumed this is how they should sound.I've only had my tank for 2 weeks and drove it maybe 10 to 12times total. Finally it locked up and I couldn't find anythingwrong with the gears. I mean, I seen slight wear onthe 3rd inner gear, but nothingthat would cause the problem I was havingof lockingup.Their was a lot of shift in 2 of the gears, so I shimmed them with washers, but still no dice. While running the motor to figure out why itwould stopafter a few rotations, I had a chance to notice thedifference in loudnessbetween theproblem motor and the one working.
I had to finally contact Phil at Rctankwars. (That dude is awesome) He sent me out a replacement and I sent him back the whole motor, in hopes he could tell me what actually went wrong. But apparently, I guess it was because the gears needed to be shimmed?
Although I just got my motor replacement yesterday,I screwed up the idler. Stripped the screw and now Ihave to drill it out. I also need to geta tensioner(since I have no idea how to make my own), the tracks keep slipping at 98 links and 97 is too tightand makes thetracks pop and crackle.
Anyway, how is the abrasive used? Just run the gears for a considerable duration to promote some control wear?
