LEGO® TECHNIC® CONTROL‪+‬ 4+

Best lego idea ever!😀

So I have the top gear lego rally car and the thing has had zero problems since I got it on Christmas in 2020. Not to be rude, but for any critics out there, when you say you have a “problem” with the app and set, rebuild it first because most of those other comments are easy fixes. As I said earlier, the cars are great and I have had so much fun with it so far: I just wish an update or upgrade could make it faster. If not possible or hard to do, then don’t bother because you guys worked hard and made a great product. Thanks once again for reading this if you do.

Surprising Every Step of the Way

I tricked some relatives into getting me the Liebherr Excavator for a major holiday fully expecting either a smarter than average Power Functions or dumber than an average Mindstorms experience. I also expected a lot of Bluetooth headaches.

What I got was nothing short of phenomenal. Connections were flawless and painless. Firmware updates were transparent—if long. The model testing along the way barely hinted at what was possible. Ultimately the total package completely blindsided me, but in the best way.

The app is flawless: it holds your hand just enough while encouraging exploration through its achievements and rewards. Don’t like multi-touch? They’ve got you covered. While I’d rather use a text editor to program it, you can get somewhat sophisticated dragging control blocks around. And they really undersell the hardware! The app shows you the tilt of the model, updating in real time—but there’s no mention of an accelerometer or gravity sensor anywhere. What other things can it do? I’m certainly curious to get the other Control+ models now!

I can’t go 5 stars, though, because the app seems hard-coded for three LEGO models. But LEGO is all about taking things apart and making your own creations too. Yet I can’t find a way to, for example, say that “port A is the release motor on my catapult” if I disassembled the Liebherr and made a steampunk trebuchet, for example. I can rebuild my LEGO bricks, but not the app, I guess.

Great, needs work

I got the top gear rally car as a gift and had a super smooth time connecting with the app. I found the calibration super useful and the manual transmission fun to use. I did have a little problem with the gyro control though, it seemed like the sensitivity was very iffy sometimes I would have to turn my phone all the way to portait mode for a turn and other times it felt like a small bump would make the car turn a lot.

One last thing is that control+ should support custom control setups because making things into other things is what Legos all about. I think the mindstorms app is a good example of a good custom control system. I made a tank with my rally car but had to use a third party app to control it.

Thanks for your time. I hope you consider my idea.
