I just got the HPI Hotbodies Cyclone S Touring car. I do notice the front tyres are wobbling during a corner and they make some weird noises. Though, the tyres are fine when on straights and slow corner. I lift the car off the ground to inspect , it does the same thing. The front 2 tyres wobble only when I steer it one direction to the maximum and hit the throttle hard. Im afraid it will cause damage over time so Ive limit myself from playing it too often. Any help would be appreciated , thanks !

Get some double jointed axles up front.

is there a temporary fix for this before i purchase any parts ? also whats causing the problem ?

You could limit the end point of your steering so that the axles don't chatter, but thats not ideal.otherwise you need to replace with DCJ (Double cardan jointed) axles. Have a look at this video: https://www.youtube.com/watch?v=09QUgX-CLZE

You can also run a front diff.

I guess I'll have to buy then :/ . Thanks for sharing though.

It is normal. Indeed, this will eventually wear out your spool outdrives and the ends of your CVD's. But we all go through it. It's not a big deal.

I don't think it's the driveshafts, especially if it does it in the air where there's no load on the shafts (or shouldn't be). I think your problem is that when you turn the wheels to the side where you noticed the problem, the driveshaft is either articulated too much or hitting something or both at full lock. Check steering lock left to right and see what's wrong.

what do you mean by driveshaft is articulating , hitting something or at full lock ??

niznai

The driveshaft can only bend so much and still spin freely. I think yours bends too much one way.

THancock

This is your answer. Do not buy replacement parts. It is perfectly normal. The chattering is simply down to the use of a spool and UJs that do not allow for different rotational speeds when the car is steering. Under load (on the track), it is not an issue.

Running a front diff will change the handling of the car and reduce drive out of the corners.

If you're desperate to spend money, buy some spare spool outdrives and driveshafts as they will eventually wear out.

im not sure how it is bending ? the dog bone looks fine to me.

Thanks . Anyway what is a front diff ? I thought every car has a front and rear diff ? Sorry for my newbieness !

To check if you have a diff or a spool:
- hold both front wheels, left hand on left wheel, right hand on right wheel.
- perform a twisting motion
- if the wheels twist in opposite directions, you have a diff. If they only rotate in the same direction, you have a spool.

Usually people run a spool in the front (a solid axle with no give). In the rear it is common to run either a gear or ball diff so that when you go around corners the wheels can spin at different rates.

In drifting its reversed (diff in the front, spool in the rear, or spools all the way around).
