If you are after kits then also available are:
- The RC8E line up, which includes a buggy (£369.99), truggy (£399.99), and a CORR truck version (£409.99).
- There is also the Ishima E Rave, which hasn't come out yet, but it won't be too long, (about £300 for the Kit (R version), (it also comes in RTR format (in both S or R versions, early indicators are about £600 for the R, and you do need a battery and charger too), this is mainly due to the better quality electronics than the Caster RTR),
- The Hyper 9E, like I have, though it won't be out for a few more weeks at least (about £400),
- Then there is also the Losi 8ight-E 2.0, which is only available with ESC and Motor (which comes to about £600 too), though you can get a nitro one and then buy a conversion kit if you don't want the Losi electronics.
As you can see though, all of these are far pricier than the Caster, but I would say, only bother with the kit, then get your own ESC, motor, servo etc, as you will probably end up replacing the stock ones anyway.
So, overall, whilst the other kits will be better race machines handling wise, if you are just starting out, go with the Caster, it will have quite docile handling, and get used to the electonics and racing before going for anything else.
