Have to agree with K Brewer, I started with a B44.1 and it is a calm handling, easy to race buggy using the initial manual settings. I run on bumpy astro and indoor carpet and whilst I was learning to drive (still learning

) did not have to worry about setup as it was neutral. Now I am a bit more experienced, I can play with the setup a bit more and it responds well.
By way of comparison my son started with a Tamiya toy buggy and he upgraded to a Schumacher SX2 and really struggled with it as it was tricky to drive and setup for a beginner. A good driver could drive really fast with it but for a beginner he found it a bit too challenging. I got him a second hand B44.1 roller for 100 quid on here and he has not looked back, not to mention only needing one set of spares now!
Loads available with spares packaged for 100 or less now.
