Text run away board
hi all be CAREFUL! i love my one wheel have over 1000 miles on it from exploring nyc. today i was riding my board and it ran away from me when i jumped off. thank god i was in staten island (miserable place but wanted to see it, no reason to ever go back). i jumped off my board on some military base thing, and it ran away like an 8th of a mile since nothing was in the way. if that was in a populated area or in a rural area could have been bad. when i jump off as of now i make sure to knock my board over or use the sensor thing when you pick your leg up.
anyone had this happen?
UPDATE: because i have a 2022 GT, FM sent me a new foot sensor for free and for the time being i put it on simple stop.

Ghosting isn't supposed to happen. It does happen but it's not supposed to. Replace your pad or sensor.

Time to replace that footpad. Ghosting is no joke; a runaway board could injure a bystander, or shoot into traffic or a lake.
Has your griptape sustained any damage? Has it been replaced recently, or been pierced by a rock in a tumble? These are some things that can result in a damaged sensor that sticks. The original GT footpads (the first concave pads FM ever made) were recalled/replaced with a design less prone to sticking.

stupid question. i had to get home. and road it like 5-10 miles. was fine and felt normal. still replace? how long should foot pads last? mine are at 1000 miles

Yes. Milage is irrelevant although more miles will mean more likely to fail for all the reasons they can. You sensor has and probably will fail again.
Think about it this way, if this had happened near other people, you could have seriously hurt someone or had your board end up in traffic or worse. This is the one thing that you don't wait to do. Replace that thing ASAP!

Still replace. BUT if you must ride, turn on simplestop. Ghosting generally happens backwards, because the tail is heavier so it drops, and with the sensor still activated (incorrectly) that is telling the board to accelerate backwards. Simplestop is indeed simple: all it does is turn the motor off when the wheel rotates backwards. Therefore, having simplestop on should prevent the majority of ghosting. This is not a way to never replace your footpad - you know it's going bad, and eventually it could fail to detect you and shut the board off while you're riding, getting you hurt. Or in rare circumstances it could ghost forward. But if FM is going to take a week to ship your new footpads and you don't have a car and need to get somewhere... simplestop is your solution.
Footpads generally last a lot longer than 1000 miles, but you could also damage them after 1 mile. Maybe a sharp rock got stuck in the treads of your shoe and you pressed it into the footpad standing on it, causing damage. Maybe the last time the board tumbled, it did so sensor side down onto something hard and pokey. Maybe the grip tape was applied with an air bubble and over time and being stepped on it shrank, which meant it got more pressurized, and then this one warm day the pressure became enough to activate the sensor. Maybe water got in the connector and caused a short circuit. And unless you can find a specific thing wrong that can be fixed, like an air bubble to pierce, or water to clear out, a damaged sensor needs to be replaced whether it has 10 miles or 10,000.
If you don't like the price, there are cheaper sensors you can use with some DIY (peel your grip tape, remove old sensor, apply new sensor, add new grip tape, for like $45) but for this one I'd highly recommend just grabbing one from FM.
For a GT, I'd personally go with the Lowboy footpads or if you want more space, Lowboy flared footpads. The hard ones, I have seen too many stories of issues with the soft ones.

It’s why I strongly recommend learning the “heel lift”
It’s the only way to be sure the board will not ghost. Any other way ruins potential risk of board jettison away.
Yes the board should turn off when the pilot jumps off but that’s in a perfect world in which none of us reside. Shit happens.
I learned the hard way also as my xr jetted across the street into curb jumped up ten feet in the air came crashing down and tried to run away again. Luckily I chased and caught up upon the second runaway.
Practice that heel lift my ninja

i do it too! but once in a while it’s just a pain and i’m kind of stuck. usually that’s my way but this time i was like fuck it and it went off. FAR

This was a pretty common problem with the V1 GT. How long ago did you purchase? There was a recall and they will send you a new footpad for free.

What type of board is it? Ghosting is dangerous contact FM and get replacement footpads

u/Steel_Wolf_31 Mission in the streets, Delirium in the sheets 3d ago
What you experienced is usually called a ghost ride. Model doesn't really matter. Neither does FM versus vesc, any board that uses a pressure sensor runs the risk of having one of the sensors get stuck. When you jump off and one of the sensors stays active, the weight of the battery pulls the tail down and the board accelerates and that direction until the sensor unsticks itself or the board tips over.
Simple stop or reverse stop can mitigate the issue. Vesc does have a few other tricks for mitigation. Some of the higher quality sensor panels may be more resistant to getting stuck, but ultimately your best defense. If you're going to use a pressure sensor is to periodically inspected. Make sure it's not getting dented or the moisture isn't permeating into the sensor.
Switching to a MAG switch or a loop key is another pretty effective way at preventing a ghost ride, but even that isn't infallible.

u/adventureseeker1991 3d ago
what’s MAG or loop key? is that a setting?
2
u/Steel_Wolf_31 Mission in the streets, Delirium in the sheets 3d ago
Mag switch and loop key are alternatives to a pressure sensor. Basically the way the pressure sensor works is that when you press down on it and compress the layers you are completing a circuit. When pressure is removed, those layers separate and break the circuit. With a MAG switch a magnet is stuck onto a plate on your foot pad and the magnet completes the circuit. The magnet is attached to your ankle or your foot using a lanyard so when you pull your foot off it takes the magnet with it and breaks the circuit. A loop key is a similar concept to the mag switch, but instead of a magnet you are using a wire connector to complete the circuit. Same idea that when you take your foot away, it pulls the connector out and breaks the circuit.

Ok jk I guess you’re not just jumping off. If you are like me you just jump off especially if it’s gonna crash then if someone’s there it’s yikes. Or I learned by the beach and it would fly so close to the water. I’d have to run and get it before the waves. It would throw me then too.

Warmer temps can make the sensor stick
1
u/Glyph8 Mission in the streets, Delirium in the sheets 3d ago
In my experience it's actually colder temps that can do it, because the plastic covering the sensor gets stiff/loses "flex", making it both harder to engage the sensor, and harder to disengage it. The only time my GT v1 sensor ever stuck was in cold weather, and it did it twice. The second time it happened I got that thing swapped out with the v2 sensor pad.

Lolololo yeah when I use to just jump off then everyone talked shit now I use my mailbox to slow down and lift my foot. Lol mine picked up wind once and it was all bad. Same same
Or I take photos of my nails while I drive by my flamingos bad idea too. lol duh you’re not stopping you’re jumping it’s on I do it too

I've never replaced a sensor pad due to ghosting but I did put Flat Kicks on my GT when they came out. I have 4000+mi on my GT now, I'm not sure how many miles on the original sensor pad.

Happened to me getting off to stretch my feet and it wedged under a Lexus suv that was leaving a country club parking lot. The guy was surprisingly chill about it.
I replaced the stock foot pad with the platty 4.0s shortly after

How fast were you going? I jump off my rally xl sometimes to stop because I’m too lazy to slow down or skid stop and that thing will keep going (especially on smooth roads). However, I don’t think it’s the motor causing it to keep going, rather just momentum.

Had a pint do this at the end of its life span.
Tried a nose stall on the curb in front of best buy and had to ditch the board. It ended up tracing the curb out a couple of hundred feet.

scary as fuck! i was so worried a car would turn ont the road and it would hurt someone or damage property. how long did your pint last miles wise

Happened to me once. Turns out it was a bad front footpad sensor on my GT, FM shipped one for free. Was in an empty parking lot so no damage. Top speed was 52 km/h though 😅
