Hi again. After the success of my first daft question about Airsoft issues, it's time for the next one.
My Taigen Tiger has a second issue that arrived with it and I need a little help please.
When I try to make a gentle manoeuvre in any direction just before the tank actually moves there is a loud buzzing/interference sound heard. I would described it as a 'feedback' type sound that you would get on a radio. I have changed the speaker and it hasn't helped. Now I've learnt how to get the top off completely it sounds like it's coming from the motor/gearbox section at the front. As soon as the tank picks up speed it instantly stops.
Any ideas or suggestions would be greatly appreciated.
Thank you.
John.

Re: Loud Feedback
Think this was covered a little while ago...but usually that squeel is from a Weak Battery

I've tried freshly charged batteries but they are all the same. Thank you for your reply though.

Re: Loud Feedback
Not having a Taigen version, could be tracks to tight, try turning your sound volume down, also try running the tank with the tracks up in the air, put a support under the belly plate & see if the sound persists .
Other than that sound, does it operate ok ?

Re: Loud Feedback
It's the motor.
Motors resonate sound, if you've ever heard an ultra micro servo or brushed motor on startup, you'll hear that squealing. With brushless setups on planes, it's actually programmed as a signal for you to recognize, a certain aount of beeps mean everythings okay and the motor is armed, so you don't loose your fingers. With the micro servos, the motors are so small, noise suppression isn't worth it.
The reason you don't hear it on every motor is a capacitor will eliminate it. If you look on the back of most 280-480 motors we use with tanks, you'll see two caps soldered to the housing and terminals. That suppresses the noise. Either your motor doesn't have the caps or they are blown.
There's no harm whatsoever, just annoyance.
My 12 year old Tamiya Tiger does it now, only on very low revs when you first start moving. It's when the motor resonates the most. It doesn't bother me, but it's easily fixed with new capacitors.
Capacitors are the electronics industry's dirty little secret. They are designed to last a certail amount of hours, so manufacturers can choose how long they want something to last. If the warranty on an item is one year, they can figure how long they want it to last based on average use and bingo, your product will out last the warranty period. Of course they can also choose for it to last 10 times the warranty period as well, it just costs more.

What, me worry?
Re: Loud Feedback
Wow! Thank you for the replies but especially for the lesson in electronics from ausf. I've learnt some new words there and it certainly sounds as if that is the issue. Is it worth me contacting Nitrotek for new bits or is it something that can be cured with a little know how and a couple of cheap bits?
Thank you,
John.

Re: Loud Feedback
It's really nothing to worry about, but if you want to fix it, look on the back of the motor, where the wires are connected.
There should be two capacitors soldered to the motor case. They'll either be little cylinders or a drop shaped piece of plastic with two wires protruding. If there isn't, then you can add two. If they are there, you can read what size they are and check if they the right ones.
You should be able to find info online regarding what size should be on it, etc. it all depends on your motor size, voltage...
The caps themselves are really cheap, mostly pennies.

Re: Loud Feedback
That is fantastic info thank you ausf and I really appreciate your help. I spent a small fortune on this 3 weeks ago and I am determined to have it perfect. The one positive thing about these annoying things though is that I am learning and get a real buzz from it. Thanks again.
Kind Regards,
John.

...Like Herman...the Majority of my tanks are HL...The noise is usually the battery is low on power...In the earlier discussion...some other Taigen owners came in and said that sound is common...And with that said...I did notice some Taigen gearboxes don't sport that diode which is common on HLs...so that could be the likely reason ALPHA
