The Baja 5B, simply the most popular 1/5 chassis to date. Compatible with 99% of the parts from the original HPI Baja 5B. Unlike the original, Rovan has pre-installed a massive 45cc 4-bolt petrol engine with a Dominator-style tuned exhaust pipe for that extra power we're all looking for!

On top of the power increase, Rovan made the drive shafts 33% larger, installed an aluminium clutch mount, steel roll cage, sway bars, MX rear tyres, NGK spark plug, Walbro carburettor and a 45kg steering servo!

As advertised and on time

Frankie Frankston
Awesome car, great fun and worth the extra effort to set it up!
4 things I recommend.
1. Loktite Everything. (Must do)
2. 7000rpm clutch. (More control and quieter.)
3. Silencer. The neighbors will call the police without it lol)
4. Symmetrical steering. (Makes it turn normally. Has the turning circle of a truck without it.)
Dont attempt the work yourself without confidence.
