Great video. We can see that the wheel stopped rotating forward and started to rotate reverse. Probably due to changing orientation of the wheel during the fly. When you landed it was going back and maybe that is why ot was not able to react properly after landing. I think wheel in the air idealy should be spinning with the same speed as before the airborne, so it is crucial to maintain the same position of it.

I have landed my s18 and Master with more air and more back spin and both have managed to catch me just fine every time. The loose gravel would have helped to soften the impact on the electrics. This is not a good look for veteran and people who want to do even occasional little jumps on the Sherman s.

We need a slightly more sophisticated torque conttrol feedback method that would allow these wheels to have less instantaneous torque applied when wheel speed exceeds ground speed . This is a software problem that causes current surge feedback issues and can blow components on the motherboard. If fixed, we could have better traction control on ice (slipping), the ability to power slide (translating) and safer aerial flight (unloading). This is easily fixed in firmware but additional code will have to be written so it might take some time before we see this core design deficiency addressed. {too bad the firmware isn't open source or this would have been fixed by the community by now.}

@grb1969
@grb1969 Год назад
@@deadmonkeyeuc2594 Not necessarily, when the wheel is “unloaded” during airtime, the current needed to spin up is minimal and this could be used as a parameter that would maintain constant rotational velocity while airborne until the current spike of landing re-engages the balance mode. The ability to measure the needed metrics already exist but the programming just needs to be improved. What is key to understand is that there are almost no circumstances where the wheel spin up while decreasing current demand (except free-spin test, for example). Torque control could result in traction control, which would make riding across “black ice” more safe; it could also make stair climbing easier too. The problems arise from the simplicity of the control method, which was sufficient for “toy” EUCs but complicates potential failure modalities for high speed/ performance wheels. My previous response was slightly incredulous 🤨 because the jump executed in the video was nearly perfect, and the minimal backspin seen at landing should well within a performance wheel’s capability. I suspect that the failure was from a faulty capacitor, which should have been able to handle the load. The trend of blaming the riders for the majority of electronics failures is simple egotistical arrogance (I.e. bullshit).

I don't think your landing was trop brusque (too harsh) but good instead although not _perfect_. The wheel was not supposed to give up balancing in that case and it's not even a high torque situation given how clean the landing: no significant forward or backwards lean. It needs to be brought up to LeaperKim's attention. Is high speed mode active?

all that forward momentum when you hit the ground and the wheel trying to go in reverse. The question is why the wheel goes in reverse mid air, is the tilt back really that sensitive and shouldnt it know if your off the ground?

Lol like the pad, the shit and debris flying back at the end. I jump my s22 everyday and do trails, because it was made for that. Perhaps use the Sherman s for a street cruiser, because that's what it is. The s22 is modular and has superior suspension for jumping and trails. The new Patton seems to be more a trail/jump fun ass wheel, maybe consider that. Hope you didn't get hurt and can ride another day. Just know what your riding and why.

do you S22 is the best offroad wheel now? V13 has "redundancy" supposedly. have you ever had a cutout?
@dirt.surfer

@embededfabrication4482 it's in a good place nearly any earlier later. Easy to work on, change a tire. And very smooth comfortable ride on the trails. I haven't tried the pro, ppl say it has more torque but apparently it's not a big difference. But getting the 8 rail suspension kits is a game changer

That isn't pedal dip. You lean back and you can see that the wheel starts roll backwards at 0:23 because it tries to ballance.

When tilting back the wheel must have spun faster. It only dips forward if it can no longer accelerate.
