The drivetrain is reinforced with 33% larger driveshafts and an aluminium clutch mount, while a steel roll cage provides added durability for extreme off-road adventures.

Wicked little beasty very fast and a loose back end great for sliding around. Not as loud as everyone makes out as loud or just a little bit more than an chain saw Definitely get the Aluminum Symmetrical Trun Symmetric Steering Kit. My stock one sucks and has trouble turning under load. But it’s great fun… almost broke my ankle lol

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.

Tips: go over the car tighten it all up,do the heat cycles then your good. You will need to carry tools as ive found out to tighten bit n pieces.WE HAVE GAVE OUR A FLOGGING and its holding up well.car wont start with choke on so jst prime it well and start very easy. Love it

This car is very strong and good for the price. I would reccomend that you upgrade it with a HiLantronics killswitch, as this works with the stock radio, and a steel front chassis brace. There are also these plastic things that keep the front shocks from popping off and they shatter on a hard landing so I reccomend you upgrade those to metal.

Verified buyerAs for speed of despatch and delivery, Hobbies Direct are great but when it comes to issues with a product, They are very slow to respond and will not send parts or reimburse for faulty parts. Would I buy from them again? Yes... but not any high value like the 45cc Rovan Baja in which i am still having multiple issues with. The emal asked for the good and the bad for this feed back, Here it is Both good and bad.

Verified buyerMy rovan Will not start, slowly pulling it apart under instructions from the hobbies direct work shop. I was hoping it would work straight away as it is classed as ready to run and cost almost $1000.
