Recently got the Mosler Gravity. This is the worst sounding and loudest Ninco I have ever owned. I was hoping the aluminim gears were going to make this car smoother and quieter than normal GTs but its worse. This car is very fast and turns great track times but I can't hardley handle the noise. I've tried loosening the gears a bit because you can feel the resistence of the motor more than most but there was no difference so I put them back where they were. Its a little quieter without the body but get twice as loud withit on.
Any suggestions to try? I really like this car but don't want to run it the way it is.
Ninco's are notorious for this noisy gear mesh. The adjustment of the pinion on the motor shaft is a well known way to improve mesh. A lack of stiffness on the chassis in the drive train area has been a limiting factor on many of these. And sometimes, the excessive torque of the Ninco motors is to blame.
Press the pinion inwards towards the motor to quiet down the gears. The trade off is a little bit of backlash on the drivetrain, but it'll quiet the car down a lot.
As Mark stated, keep making small adjustments by moving the pinion in on the motor shaft until it gets better. Once you get it quieter, try taping or hot gluing the motor to the chassis. This will stop the motor from rotating in the chassis which helps the noisy gears and will improve the handling of the car as well.
Also, you can apply a small amount of metal polish or even tooth paste to the gears while running the car. Once the metal gears break in, apply a small amount of grease and the gears should be noticeably quieter.
Be patient, the metal gears are more reliable than plastic and will usually get smooth and quiet with a little effort and run time.
All of my anglewinder Lightnings were/are very noisy when new. Unlike many slot cars that need 100 laps to break in and quiet down - I have found that these Lightnings need more like 1,000 laps.
I had forgotten about my original Mosler Lightning because it had a bent rim. It had several hundreds of laps on it and I remembered it as being noisy. On a whim I swapped out the bent rims and cleaned it up and lubed it and put it on a wood tri-oval track.
Wow.
First, it was fast as stink. It ruled the track except for the spare Slot.it with a 36k-40k motor and foam tires - which couldn't put 10 laps together without crashing. Second, it was surprisingly pretty quiet. Part of that was my "loving on it" and getting the rear axle set up right. Part of it was that it was finally broken in. After about 200 laps it got really quiet and starting shaving tenths of seconds off the lap times.
Now I do use a tiny dab of my special "secret" gear grease on the gears before each running because it is a metal to metal gear mesh - which seems to help. My secret gear grease is Tamiya 4WD grease for their old "free-flight" cars.
