RB5 Proline wheels problem ???

[Rob Fitzgerald]

Hi Guys

I am hoping one of you lot knows what I am doing wrong.

I have a nice new RB5 and a set of the adapaters to fit proline rear wheels - but it wont fit ? - or am I doing something stupid.

Now I assumed the ally flanges need to slide up the shafts and the pin slid through ? - But the holes in the flanges are not big enough for that.

So - what am I doing wrong

TIA
