Awesome little model! It may use RC components, but it's still a clever build with a great looking body :)

Thank you!

Well.. it's not meant for high speed, is it? I think if you gear down at the motor (12:20 instead if 16:16) you could solve the cogging and the too fast top speed issue.

True, and I believe a slower gearing would help with the cogging (actually the current gearing is 20:12, so even a 16:16 would be enough I guess, but then I'd have a large gear sticking out at the bottom in the middle, limiting passability) and also, with slower gearing the slow startup mode of the motor would become too slow and useless. But maybe it would not even be needed, don't knwo, needs more experimentation.

It does! Really liked the shots. Can we see the setup? I wonder how low does it go.

Sure, so this is the piece I printed to attach to the bottom of the transmitter and create a 'tunnel' for the stick:

And it looks like this when put together. My selfie stick is not very long, a bit longer one would be more comfortable, but it's good enough. At least it has a button on the stick to start/stop recording..

That does perform very well! Looks very fun!

I guess the more power and speed you get out of the motor, the harder it gets to control. I'm used to Lego models where you just give 100% throttle all the time, but for most of those shots you would have been nowhere near that! It must be harder holding the stick in the right medium position

Yeah, indeed, most shots were using just a little throttle, I had a similar feeling, that I'm used to less speed and hence less control problems with my Lego models. And the bigger difficulty is keeping the model within the view of the camera for a long enough period of time. When going fast, or just trying to maneuver precisely, I either wander out of the view, or if I look at the camera, I soon crash the model into some rocks.. It takes some practice, but I realized that if I'm at a good distance, and point the camera generally in the right direction and avoid moving my hand too much, then it comes out okay. And of course when it does not, I cut the scene :)

Great! Sadly this year prolly we won't be seeing any C model of an official Lego Technic set from you?

Thanks! Well I only bought the Bronco this year, and I am kind of struggling with a good idea as most have already been done..

Great job, Viktor.

I already said few words under your YT video, so I will not double myself. I will just add few comments from my side.

• You don't need to make a separate topic. I would just change the title from WIP to MOC. You can reorganize the first entry, but it is up to you if your topic needs that. ;)
• Regarding cogging effect. The easiest way is to gear down, but I too sometimes feel like there is "jump" between sinusoidal startup and normal motor run. You can tune the behavior in ESC_Config_Tool, but as you don't have PC currently, maybe there is a way for you to do it through Wi-Fi. I didn't dig deep into this topic, but I saw people using the phone to change settings of AM32 device. As you have a model already built, you can adjust your settings to that model. I am not saying though you will have to do it every time you build a new model. ;)
• I need to do something similar with that "Camera holder" under the transmitter. I have a lightweight mirrorless digital camera, so I think I could give it a try. Thanks for the tip. ;)
