LEGO - Technic App-Controlled 4x4 Mercedes-Benz Zetros Trial Truck 42129

Great looks but it is a bit slow. Should have a higher speed forwards.

Got to the end of bag 3 and tested the motors and gears as I've heard that gear cracking is a common thing for this set only to realize that 2 of my motors were the wrong way, the only way to tell that is through the app which I shouldnt need to check as I'm building. Now I have to take it apart and go back to steps for bag 1 because they couldn't number the motors or colour code them, have always been a fan of Lego and wanted a more complex set as an adult but just find myself frustrated when building it and not enjoying myself. The features in this set are still good but having to go to the first steps again has really put me off building the set

I am in awe of the locking differential on this truck and the 4 motors that run the vehicle. I own the Claas tractor anthe Mack anthem batwing and the new tumbler. I am 44 and still love Legos since the 80,s. The new Bluetooth remote hub is awesome. I hit a 39 degree climb on my sons long skateboard it was amazing. This truck is a powerhouse and I am driving it as we speak thank you Lego for suck an amazing vehicle

It is a very good set as there is a fair number of piece count however some adjustments could be made. e.g., the hood could be more secure and so could the door, which easily open when on a descent. The gear ratio is very slow but it works for a ramp. Speaking of which, the climbing ability is amazing! The new tires really affect.

So From the minute the set was officially released to the public, I knew I had to make drastic changes which is what I did. So I added additional axle and converted to crew cab. Replaced the rinky dink tires it came with 3rd party tires made out of real rubber. Looks much better and can climb between 49-54 degrees angles with zero issues.
