B4 Buying Advice Please

[bertberr]

Hi, I'm looking to start 1:10 elec off road racing as a beginner, and will be visiting my nearest track in March (Tiverton) when I'll hopefully get some more advice, but in the meantime can anyone help with these questions?

Looking at either new RTR or second hand kits, but I can't work out what the difference is between the B4 RS RTR - http://www.modelsport.co.uk/?CallFun...n&ItemID=25206 and the B4.1 RTR - http://www.modelsport.co.uk/?CallFun...n&ItemID=35111 ???

From what I can see the 4.1 has a 3 channel radio (not sure why you need this in a buggy) and a different ESC, but what else is different / which is better?

How would these compare to a second hand B4 off the bay that may be a few years old? I've seen them for between £60 and £100 second hand, with the higher priced cars usually including esc / motor / servo etc. I think the earlier (pre 2008?) cars had a graphite chassis that isn't supposed to be as good as plastic, so this may be a good reason to go new RTR, but any other issues I need to consider when buying second hand?

Cheers
