The new Division definitely shows more improvements and looks better than before. New motors, new wheels, and slightly new body. Looking forward to see the New Division in NHRL August soon.
For what it’s worth, on off beat’s minibot, we run what is essentially a beetleweight drive (1522kv hyperlite 2203.5 brushless motors.) The wheel axle is retained on two sides, that being a threaded feature in the drive pod, and on the outer wall of the drive pod. I can send some pictures if you’d like, btw! But to make a long story short, try some wheel guards!
Yoo William Osman! Was not expecting that. Division is chaos incarnate and that's awesome, but sometimes it works against it, so it's nice to see that the issues can be addressed so we get to see more of Division!
On my tangent drive the shaft connects all the way through, ill see if my wheels stay on. Those brushed drives you sell kinda makes me want to switch too. Im excited for the Open Sauce video, feel free to break it into a few videos. Im sure there's lots you did there!
You may want to mention somewhere that the current rating of a brushless to brushed esc conversion will go down due to the duty cycle tripling on the active FETs.
@@JustCuzRobotics When a brushed motor is going forward at full throttle 1 high side and 1 low side FET are running at 100%, the others are off. A brushless motor should be splitting that work over all the FETs (still 1 high and 1 low on at a time) as it cycles through all the phases. That said, how the heat sink pulls away heat and how the duty cycle exactly affects the heat growth is more complicated than just a simple 3x and would require testing (or maybe an electrical engineer can calculate it, I'm not one).
I see, that makes sense. I am also not an electrical engineer, I'm mechanical by formal training and employment. Fortunately the vast majority of brushless ESCs out there used in combat bots are 30-35A rated and while these current ratings themselves are a little suspect, that is many times more than the 3-6 amp stall that most brushed motors have. The ones I'm using stall at ~13A but realistically will never be stalled during a fight and I'm using a 35A rated brushless ESC. So I'm not concerned for the ESCs at all.
Wow interesting upgrades but out of interest why not try and do a brushless conversion with the dartbox gearboxes? Also I enjoyed the sneak peek of Open Sauce and am looking forward to that video.
Why mess with tiny brushless motors? Brushed motors provide instant torque and I find that the bot drives super well with them. Swapping to brushless would just bring back the sensorless startup problems I had before. Besides, I sell these complete with brushed motors and have a ton of them so it's as simple as swapping to another gearmotor if one fails.

0:50 - Oh hey, I was watching that fight! It was still awesome to see Division in real life. And in your defense, Caldera is a monster.
Yeah Caldera is absolutely a beast. Its performance at Open Sauce continued this trend

Wheel guards are a whole other can of worms. I don't have weight for anything like that right now

For me the failure was always that 3D printed mount piece. It just wasn't possible to make it strong enough.
Do an am32 tutorial it would be awesome
Those were a lot of big names on youtube at that fight, wow

I actually wasn't aware of that. I thought it would be 1.5X not 3X

@@JustCuzRobotics yeah, I expect it to be fine in that case. Just thought it was worth mentioning as it's easy to think 35A is still 35A.
Yup. Definitely a point I appreciate hearing.

Do the AM32 brushed firmware on brushless video
On your site all the youtube links for your videos are dead
you might want to have a look at that
just a heads up love what your doing
On which page or pages? I don't see how it's possible that every link is bad.

Make a tangencial loc (same than AGVS combat)
The only thing tangential drive will change is the gear reduction. It wouldn't solve any other issues I had

i love your vids
