TECHNIC MINI DUO CONTEST - DISCUSSION TOPIC

Because two are better than one.

DESCRIPTION
Build a Technic Duo MOC with two separate MOCs, each weighing no more than 300 grams. The two MOCs should be two separate models and not a car and a trailer. The two MOCs do need to match thematically.

VOTING CRITERIA
Voting will be 100% public voting, but the votes will be cast on an external website and won't be visible during the voting period. The voting criteria are (in no particular order):

• Duo theme
• Quality of the build
• Functionality
• Originality
• Looks (shape, color scheme, etc)

DEADLINE
Deadline date is February 9th, 2026. Contest will be closed on Tuesday the 10th OR LATER. 

Disclaimer: I will close the contest when I see fit and when I have the time to process the results. This can be later than the deadline date. Please don't complain about this not being fair and all.

So entry need 2 model only not combination model?

[JoKo]

That's a well balanced theme. Simple but interesting, thanks!

Now my kitchen scale probably left the kitchen for a month

Okey

Is this rule 'single battery box and four motors' is effect on both model or single model each?

Each model needs to weigh no more than 300 grams, so you better start thinking about ditching the electronics 

I have removed that rule entirely.

We could even ban electronics because non-lego seems the only possible way.

[Jim]

We can also ban every element weighing more than 300 gram

If that exist that's already explicitly banned if I can read.

What I mean is a little buwizz RC car seems possible within 300g and I don't know if that's the kind of MOC you are expecting
