There are a lot now days... I'm sure I've forgotten a few, but here are the ones I can remember:
- Xray M18T, MT, Pro
- Duratrax Vendetta, ST
- Kyosho Mini Inferno, ST, 09
- Losi MLST series
- XTM Rage
- Trinity Now
- Cen MG16
Other Crawlers:
- Duratrax Cliff Climber
- Hot Bodies Mini Zilla (discontinued)
My favorites are the M18T series and Vendetta series, with Xray holding the top spot. M18T's are just a joy to drive, even totally box stock (rtr). The parts quality is second to none and they are the most agile of the bunch.
The vendettas are also great, but they come in second solely for the fact that they require upgrades (ball diffs, steel cvd's, new electronics) before becoming reliable. Once upgraded, its hard to find a better driving, smoother truck/buggy.
