F103LM = old version, discontinued few years ago, LM's lower chassis plate is wider than F103RS/RX/GT and is good for Le Mans shells, use 103 specific tyres, which are rare now
F103RS / RX = old version, narrower lower chassis plate (which can accomodate F1 shells, also use 103 specific tyres.
F103GT = New and just released earlier this year. Uses 1/10 touring car tyres, which is widely available.
I have never tried, but I think F201 can use F103 shells, but some modifications are required.
Hope this helps |
