App-Controlled Top Gear Rally Car (42109)
App-Controlled Top Gear Rally Car (42109) is one I am happy to have in the library. It has the right sort of Technic appeal: enough going on in the build to justify the time, and a finished model that makes sense on a shelf when you are done.
Set details first: 463 pieces, released 2020, with a launch RRP of £129.99. The category matters here too. This sits in the Car side of Technic, which means I judge it by function and build feel before I worry about how dramatic the box art looks.

The Top Gear Rally Car has a strange place in Technic history because the app-control idea was doing a lot of work.
The useful way to judge App-Controlled Top Gear Rally Car is to ask what the build gives you beyond a finished object. Technic needs movement, structure, or a clever mechanism somewhere in the process. Otherwise it is just a model made from beams.
At 463 pieces, this is not a throwaway build. It needs enough detail to justify the time on the table, especially for members choosing their next kit from a library full of strong alternatives.
This one is in the Brick Club library, so the question is simple: would I allocate it to someone who wants a proper Technic session? Yes. It has enough substance to feel like a considered choice, and it gives members another route through the catalogue without buying and storing the set permanently.
That is the useful thing about a broad Technic library. You can move between cars, machines, aircraft, and oddities without every build feeling like a repeat of the last one.
When I am deciding whether a set like this deserves attention, I am not only looking at piece count. I am looking at the shape of the build: whether the first half gives you proper structure, whether the functions are still visible once the body is on, and whether the finished model has a reason to be picked up again after the last bag is empty.
If App-Controlled Top Gear Rally Car is on your list, I would treat it as a proper build rather than filler between bigger kits. Give it the time it deserves, especially around the sections where the function is built into the frame.
That is the difference I want these spotlight posts to make. A product listing tells you the set number and the piece count. A useful Brick Club post should tell you whether I think the build has enough about it to earn a few evenings on the table.
Drop a comment on Facebook or Instagram if you have built this one. I am always interested in whether the finished model lived up to the reason you chose it.
