Sorry for posting all the newbie threads, but I've jumped straight into the deep end with rc cars!

My new problem is, that i was out using my car and it was going fine, but it just stopped. The engine is still working, but the car just wont move when i rev it. I noticed that when i rev it, the two gears attached to the motor do not move at all.

What could the problem be?

Thanks.

It could be your clutch. Some things that might help would be to say what car/truck you have, was it rtr, was it used, what engine is in it. We need all the info before we can help, and when you say what car you have people with the same one are more likely to chime in and help out.
 
Ok, its a v-one rr, enine is rb concept x12. It is used. Had plenty of compression.
 
Check the clutch pad/bell, thurst bearing, engagement point on the centax, check to see if the spring is broken, and check the flywheel. Of course to do this, you'll need to disassemble the clutch assembly. I'm sure it needs a rebuild anyway.
 
I have this car and know it well.
Check the belts. Sometimes a small rock or pebble will get stuck in one of the pullies.
Happens all the time.
Get a flash light and check the pullies all around.
It might be hidden in one of the grooves.

You might want to push the car backwards and see if it frees up.

if the CB don't spin I'd concentrate on the stuff Diver listed......Clutch/Flywheel/Bearings
 
The cb will only turn forward if its a rock. Not backward.

It was just a suggestion.

He said that when he hits throttle, the cb wont turn.
A rock will do that as well.

In my opinion, it would be easier for a noob to look for a rock first, then to take the car apart.
It was just a suggestion. :smoke:

I agree with Ratzo. take special care to examin the entire outside of the rig first. every nook and cranny.
 
Ratzo is correct. I forgot that he said that he was new to the hobby. A centax can be a pain if not adjusted correctly for engagement and endplay.

Check the belts to see if they are even still there! If it has snapped, frayed or dislodged, that will keep anything from moving and that is most probably from a pebble as well.
 
I checked for rocks but could not find any.

Sorry, but I have no idea what these things are!

Do you think maybe i should take it to my local hobby shop to fix? They charge $25au per hour though, could it possibly be a big or small job to fix? Id rather fix it myself though if it is possible with no experience.

Can you turn the clutch bell by hand, in either direction with the wheels off the ground?
(the two gears on the motor)
 
Yes, but it gets to a point when i turn it in both directions, that it just stops.
 
The car has 6 pullies. You checked every groove for pebbles?
Is there a part of the belt that has a lump on it when on the pully?
This is the easiest thing to look for.
If not, you will have to pull out your engine and check the clutch.
That might be a bit much for a new guy.
If you do, make sure you place all the washers and parts in a way that they will go back the same way you removed them

First thing I would do is move the engine away from the plastic gears and try to turn the plastic gears.

Do that and get back to me.
 
Alright thanks, I will try that once i get home from work today.

Sorry, i don't really understand this. As far as I can see, the engine next to the flywheel is connected to two small metal gears, which are connected to two larger metal gears.
 
AKA, take out the engine and see if you can turn the spur gears freely. If they move, then the problem is with your pinions and clutch bell.

All those things I mentioned are in the clutch assembly. You need to tear that car apart and learn it. The thrust bearing needs to be regreased every so often (about 8-10 tanks) otherwise it WILL explode inside the clutchbell. If that happens, then that can be another source of problems.
 
He needs to look at the exploded view and get familiar with some of the parts and what they are called.
Then he will know what we're saying.
