    I could upload the entire converted ldr model but it is based on @Philo's model, so idk if i'm allowed to share it or not. I'll leave the file author as philo since he did the hard work of making the model (I don't have anywhere near that much parience!) so as long as its OK with philo, Ill share the LDR file.

    Better late answer than never ;) Feel free to share it or any similar work I did!


  2. Thanks @shroomzofdoom! The fact that LEGO supports the id of the small motor on Technic and RI hubs proves that they consider it to be compatible. Of course the may have capped the duty cycle to limit effective voltage on the motor. Anyway, DC motors are very rugged and the real limitation would be power dissipation in the motor. But we won't ask the puny small motor to make the work of an XL one ;)

    Small motor:

    The big question with the small motor is voltage... according to specs its max voltage is 6V. If we take that strictly it is not compatible with Technic hub. Note that Pybricks has a special setting to limit voltage for motor output. Unfortunately I have neither the hub, nor the motor to check deeper.

    Does anyone have a Studio part for 69633?

    I looked on @Philo's page (https://philohome.com/studio/packs.htm) and didn't find it.  It's of course not in the official Studio release yet.  Thanks!

    I made the part, and it's available on LDraw parts tracker (https://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/67498-f1.dat) but I've not yet created a parts pack. I was waiting for the blue spring shock absorber, not yet modeled.

    @Phondly Hey, the design is neat. My lesson learned is to make it possible to disconnect the battery from the circuit. The step down converter in my lipo battery box always burned some energy (don't ask me why) and thus managed to deep discharge and kill the lipo while it was not used for some time : ( 

    Not sure if it applies to your setup

    Yes, that's one of the reason why I didn't try to follow the route of output converter (the other beeing simplicity!!!)
