RE: $350 or less nitro RTR 1/8 buggy
I would start off with the Hyper 7 TQ Black. Best sub-$350 RTR buggy you can get for club racing. Tons of upgrades, comes with a race legal .21 engine, tons of parts support, and is a very tough buggy. The first upgrade you will want to do is a good steering servo and a good remote. After that, a good high power .21 when the one that comes with it wears out (you should get at least 3 gallons of fuel through it before it needs to be re-built or replaced).
