Was a fix found? I have assembled the front wheels and both sets of bearings are fall out loose  Done: McLaren MP4/23

No not really. Dylan tried a few different size washers on his youtube video build diary, but there were a few problems with that. He did paint and clear coat the rims though and that seemed to help stop the bearings falling out of the rims.

Hi guys, I might have a fix for this problem. I am just waiting for an answer from Tomick. It's not the fall that kills you, it's the sudden stop

The 3wheels I have so far the bearings are a good fit not loose at all

Hi folks, Tomick has confirmed what I thought  with my scrambled brains. The wheel rims are ABS plastic with a "chrome" coating. I want to do a test or two but I think I have a fix for the loose wheel bearings. It's not the fall that kills you, it's the sudden stop

Someone needs to set my right here.
My 2 wheel's (so far) have a total of 4 bearings, they went in easily and do fall out off I give them a little wobble. Handily, the wheels are held on by a huge nut which stops the bearing from falling out.
Why is the fact that they aren't rammed mega tight into the wheels causing everybody issues? It doesn't appear to affect the running of the wheels when on the car.

Time will tell when we burning it down the main straight at a 140km
Quite possible the kill switch will come in handy when the wheels fall off !

Meanwhile, the reality is that they won't!

Quite possible the kill switch will come in handy when the wheels fall off ! How can they fall off ? There is a nylock nut holding the rim on to the axle which will stop the wheel coming off . Only way a wheel will fall off is if the nylon on the inside of the nut is stuffed .loose bearing won't cause a wheel to fall off on a r/c car

I think Nightrider was being funny and I certainly got the joke but to be clear there is no way the wheels will drop off unless you've been following certain YouTube videos  Maybe all pit crews should have a kill switch for when the wheels come of in the pit lane, that way they won't have to run so far to retrieve the car!

Ok Tomick, I said that I had scrambled brains, so they are painted. Too much RF going through my skull. My fix is as follows: Give a THIN coat of glue to the inside of the rim where the bearing fits and allow it to dry completely (24hrs). If the bearing is still loose, give it another coat. I will be using either alaphatic wood glue that dries nice and hard or Tamiya cement that come with a brush. As I said, this is what I will be doing. Each to his own. DO NOT GLUE THE BEARINGS INTO THE RIMS. It's not the fall that kills you, it's the sudden stop

You are forgetting one thing... that the bearing must be set perfectly central, otherwise it will result in a concentric movement of the wheel

Did not forget about concentric movement. The layer should be so thin that off-centre movement should be non existant. If the bearing is so loose, your concentric movement will be there. As I said, each to his own. All we want is a slight building up of the surface. I do realise that at the scale we are building all faults will be magnified. It's not the fall that kills you, it's the sudden stop

Hi Nightrider, I know what you meant. Life's too short so let's have some fun  It's not the fall that kills you, it's the sudden stop

Is exactly what has been found in Germany where they are now at the point of being able to run the car.

Just a note of caution to those thinking of securing the bearings into the wheels, you do not recieve bearings with the wheels and tyres of the RB7 series exstension (101-115). Regards Spencer
