Thank you for your reply which seems to confirm my findings. I was relieved to find this set before it became retired but in some ways I am very disppointed that I paid a lot of money for a flawed Lego set.

I have become increasingly frustrated with this model. I initially could only get this CAT D11 to fully calibrate if i reinstalled my existing Control+ App and double checked all my Linear actuators were all at the printed instructions desired extended length. This was accompanied my much gear clicking but it all ended fine. However, my ladder eventually ceased extending fully but there is no way I can get this model to recalibrate again past the front blade calibration which never completes. This is the worst implementation of a Control+ model that I have encountered so far, all others works flawlessly even with recalibration. I have resorted to performing my own "calibration" just to get things working properply and this is ironically most troublesome with the ladder. I now have all the functions moving so that the acuators don't quite bottom out but still allows a full range of movement. But this doesn't apply to the ladder which incorporates a clutch thus its more troublesome.

There is no love for Control+ on this Forum although I have no issues with it either.

With reference to my earlier (edited) app problem I also contacted Lego. After a little troubleshooting which centred around did I have the latest App and Firmware revisions I received a final reply yesterday: Hi William, I'm glad you were able to get this set working, even if it's not the ideal control method. I have been advised by our Digital Product Support team that this is a known issue and the developers are working to correct this. Thank you for your feedback and troubleshooting on it, your info has been passed on! If I can help you further, please let me know! So it seems the App interface for the default controls does indeed have a direction issue!

They are not meant to cross, the fixed wiring of the left motor goes to the left side of the control box and the right to the right side. As both motors are linked by a central differential I am mystified, but thanks for the comment.

Hello, I am looking for some advice. I finished my build today and I belivieved it had tested OK earlier in the build. On the default controls in the App when "Drive" (Forward) is highlighted it goes in reverse but when "Reverse" is highlighted moving the throttle drives it forward. I am a bit baffled as I believe the two motors involved in driving the vehicle are directly linked to a drive hub on either side and linked by a diff in the centre. So its as if the controls need reversing which doesn't seem possible? So please, any clues from someone more knowledgable than me? EDIT After a nights sleep I have solved the problem. It was a misinterpretation of the default App controls on my part. Changed to the alternative controls (Joystick type) and tthe direction control is perfect.

Glad you got the outcome you wanted.

Is it this store? They advertise delivery (free over £75) and worlwide delivery? LINK

Fantastic & congratulations its next level.

It doesn't get stuck for any other gear change so I don't think it would change for 3rd back to 2nd but thanks for the reply. UPDATE: Strangely 24 hours later ALL the gearchanges are performing perfectly ????

I recently had doubts about the gearbox despite double checking and its true the red beam solves all at the very end of the next bags of parts. However despite fixing 99% of the problems I now find its hard to shift from third back to second although it moves fine if I assist by attempting to rotate the the selector drum with my thumb. All other shifts work fine. Obviously I can't do this now the build is finished due to fitting fairing parts.

You inspire me I don't post often anymore, I recently purchased the Yamaha motorcycle but it hasn't arrived yet. My ultmate goal is the Lego bulldozer which you are currently building.

Have you got anything positive to add to this thread aside from bickering??

I was unable to view the pictures or movies and don't have that model but what happens if you swap the motor connectors 1 & 2 and 3 & 6 on the control box(es) does the issue resolve itself.

Thank you, unfortunately Buwizz exposeses another gap in my knowledge but I guess we are all on a learning curve. Would I need a genuine servo or is there a Buwizz equivalent?

Two questions from someone who owns the Zetros and a 2007 PF IR remote controlled bulldozer. 1. Why is the PF Servo so expensive to purchase? 2. How do you control this fantastic creation - I couldn't see any PF IR modules installed?

Hope you sort it out its a great model, although not fast by any stretch of the imagination.

Having recently built this model I did not find any issues with the instructions.

I remember building Bruno's Red Supercar and hating the chromed wheels. I substituted with Sian wheels & tyres but if I remember correctly I had to replace the hubs, discs & brakes as well. It definately wasn't just a case of replacing the wheels and I am disappointed that yet again Cada choose chrome wheels. To me they are something you won't see on a current supercar.

Seems I will be buying my second CADA Supercar soon. I have Brunojj1's red car (non motorised). @T Lego - Fantastic achievement and awesome feature set.

I have learnt I have an adult compulsion to spend £0000's on Lego Technic. An unhealthy habit for my bank balance.

I have no idea how to successfuly display pictures but perhaps this will show it.

The Amazon Zetros arrived earlier and I was surprised that the battery pack/Bluetooth module had no screws. I then downloaded the instructions using the Lego App on my Ipad. Turns out by the end of Bags 1 that I have the V1 Zetros and surprisingly the App instructions are also V1. I found this out by watching the video posted a little earlier in the thread. I then downloaded the PDF from the Lego website and its V2 and so I am now building from this. TBH I am surprised about two things: 1. The V1 is still on sale. 2. The Lego instructions via the Lego app are still V1. Thanks to the Forum I can sort this out and build the newer version.

Currently available for £144.31 in the UK from Amazon.

Why don't you list all the items in the inventory the whole thing seems to be a bit of a scam.
