Review: Great set - This is another great set from lego, good piece count, interesting build, lots of detail too, I like that it has motors, making it a good trial truck, that is very capable off-road, it's very slow, however speed isn't a requirement when climbing 45° plus inclines. The set itself has 4 wheel drive, with a lockable diff, switched remotely via the control+ app. The set is quite sturdy and robust, however the doors and bonnet tend to open up when travelling down-hill, especially it the surface is rough, this is easily rectified using some half pins in the door which locks into the door jamb, and one in the bonnet that locks into the bulkhead. Overall the set represents good value for money, considering the reduced price i bought it at and that the rrp is £265. Highly recommend this set.

It's lego as usual great to build

### ⭐⭐⭐⭐⭐ Technic on Top
*by L***E on 11 December 2024*

This Lego technic set really is a great build. If you like technic builds there is a lot to this model which you don't usually see at this price point. The remote/power functions are a great addition that I wish more sets included. Yes it isn't the fastest and the ground clearance is the best limiting its initial climbing capabilities but it is still bags of fun!
