Beetle Steering Issue

[calvinhwang]

Hello all,

I just completed restoring a Monster Beetle. It runs great.

However, I have one thing I want to clear up.

When I accelerate as I turn right or left, the wheel wabbles.

Is that normal for a beetle or blackfoot or is that something that can be done by adjusting?

I just wanted to find that out.

Oh by the way..Any Modification I can do with Monster Beetle?

you guys have been helpful on the issues I had.

I want to thank you and I will thank you in advance for the reply.

Thats kind of a "bump steer" effect, the chassis is well known for doing it and it's not too easy to get rid off.

I'm going to add a better servo saver to my beetle soon, which will hopefully help reduce the problem.

It's caused by the angle of the steering rods and the way they link to the servo, as its just a basic 2 rod design. Better servo savers with less slop will help reduce it.

Also, watch that the tyres haven't flat spotted - as this causes wobble too.

As for modifications, Team CRP made lots of nice hop ups, many of which can still be found today.

Here's my modded beetles chassis:

The CRP chassis bracing is a nice addition to the chassis, it makes it a fair bit tougher. The rear suspension bushings are also great, along with rear suspension mounts, front knuckles, differential bearing supports and more!

The ultimate in upgrades for the chassis is the Thorp Dirt Burner ball differential. They are rare, and not cheap. But well worth the effort in tracking down as they replace the weaker geared differential.

Dogbone drive shafts were also made by Thorp:

but you can get re release frog ones now, which are just as good but not as expensive.

Hope this helps!

Thank you very much for the reply, mymonsterbeetleisbroken.

I had to use the new servo savor since I got a used MB from Ebay.

the wheels were still wabbling turning corners. (also, the servo saver metal part from MB parts do not fit anymore since the new servo saver is bigger than stock)

I was thinking about upgrading steering rod to screws from the pop-in design.

I thought wabbling is caused by the loosen rods. or it could be that I need to use Hi-Torque Servo (Currently using Futaba S3001.)

Also, thanks for the modification ideas.

I will let you know if I find something out about wabbling.

thanks again.
