Questions regarding MOD Ferrari 488 GTE

[Tobykeys]

Hello,

 

I'm Moding a Ferrari 488 GTE with four BuWizz motors and a 3.0 BuWizz Hub.  As you can see from the first picture, the teeth of these two gears that are circled in red are slightly apart from one another.   When I drive the car, I often start to hear these gears start to click (skipping). I'm assuming they are pulling away from each other because they are not strong enough to hold in place and turn the axle.   Any suggestions for moving the teeth of these two gears closer together so there is no gap between them?

You need to add bracing to the gears!

[Zerobricks]

Don't use the same gear that drives the differential, since it tends to bend up and down when going forwards an, backwards. Use a second gear, which is properly fixed on both ends.

[Tobykeys]

We have a number of braces installed.   We are trying to figure out how to raise the lower gear slightly up to make that good contact with the upper gear (or lower the top gear).   Does that make sense?

Zero Brick: Thanks for your response.   We do have two gear connections- see photo below.

MORE BRACES!

[Tobykeys]

Ok.  Got it. I'll put in more braces and let you know how it it works.  Thanks whitepen!  

[Zerobricks]

Use T beams to brace the gears. Pin and axle based connections are bound to detach/slide apart over time.

@Tobykeys Anytime! Can't wait to see the final product!

Whitepen and Zerobrick: THANKS SO MUCH!  It now works seamlessly.   Problem solved!! This has plagued my builds for a couple of years.  

 

Zerobrick: by the way, the BuWizz motors are so fast! You can literally feel the power. Very exciting!  

[whitepen]

Great to hear!

[Tobykeys]

In the BuWIzz App, when we calibrate the steering for an extra large PU motor, it does not center exactly.  The wheels tend to be pointed about 10 degrees one way or the other rather than going back to center.    Any suggestions for a fix? 

Thanks!

Just curious to know what is the fastest gear ratio using four BuWIzz motors that still has enough torque to move the weight of the car.  Thanks!

Hi! You don't need to make a new thread for every question. Rather, you should raise these questions on your original thread.

This prevents too many threads clogging up the forum.
