@hydropage Sorry to hear you nosedived. Do you recall the events and conditions prior to it happening?
Like the type of terrain, estimated speeds if you can and if there were any obstacles like rocks, roots or some other object that could have contributed.

It may be worth recording a few rides using the app and seeing what sort of utilisation the board is under especially in the area it happened to try figure out a possible cause for the nosedive to occur without any noticeable warning.

@jayjay That's weird?
What does the app look like. Could you share a screenshot

Updated the groups to include some of the newer models like the GT-S XL since I know at least one of you lot own one 🥳 (I'm jealous)

I don't think there's really any others I need to add unless anyone thinks the Fungineers X7/X10 boards deserve their own group(s)?

@justinxr Could be the corner bolts that hold the end of the rail down to the bumper. I usually forget or just don't bother adding those ones since they can sometimes get stuck.
If you remove the footpads you can check those either end without having to take it all apart again.

If not those there's 2 that directly hold the controller box to the rail rather that passing through the bumper you can check.

@lemur thank you

@cw_o Best of luck with the swap :)

When you do boot it up lemme know what the hardware version (42XX) shows as as I'm actually curious if there was a batch that had the alternate design.

@lia It worked

I did get something else, more on that later

I think

@ikaruspint Yes, the 2n7002ps-115 are the correct mosfets.

Baby snapping turtle. I got it off the road once I saw it.

Update: I'm pretty sure it's doomed. I'm not sure I can fix that. Let me know if you still think it's salvageable. Not really sure what would have caused it. This is what it looks like under the balance connector.

@cw_o Welcome :)

If the price is okay I'd take the risk. Getting actual chips from companies like Mouser, Digikey and LCSC can be pricey once you get to the shipping screen. I've gotten chips from eBay and AliExpress (likely the same source) without many issues for things like IMUs, Mosfets and a handful of logic ICs.
Get multiple though just in case you need to redo it. No more than 5 should be fine. IMU's are fragile so you may need to try a few times.

@lia Update: It is indeed NOT fixed. After 2 half charges, the symptoms returned. I have noticed that it happens when going uphill. Going to do some testing on the BMS and see if I can track down any faulty parts.

@cw_o You can try NRF or DigTilt to recalibrate the imu, have the board level when recalibrating.

@lia Tire is good, but I'm only a couple rides in. I've been trying out different ride modes, so not sure what's the tire and what's the mode/settings, LOL. I have not noticed any real edge when carving, so that's good. Size increase might also be a factor in why the bumps feel smaller.
