interesting. I got a remote no receiver from someone and was trying to get flipsky to sell me a receiver. they refused. guess I wasn’t persistent/persuasive enough.
Lol Germany? Newark Delaware is mid-east coast US

This was awhile ago last year.
I contacted them through email and asked.
After several emails through a week period they sent me an invoice and I purchased them.

I think I’m tying the failure on this VX1 to breaking potentiometer wires.
After the fix, I test rode this remote for a a few miles and the hesitations which were near constant were gone.
I think the hesitations were the result of a slowly breaking wire.

I thiiink i’m in the same boat right now. I accelerate and get 2 power spikes before it stabilises somewhere in between.
Could be this or the receiver, which will probably need wires soldered directly. Or the canbus, but i start to doubt it, it’s thicc silicone wires from trampa
Although i’m a bit anxious on operating on the single remote i have, i will open it up in a bit and start tugging on things.
Will update

Okay, opened up the remote, all the solders are spotless.
Unwrapped all the tape and foam off the receiver, applied a mild brake with the remote and moving the receiver wires sometimes makes a static noise in the motors, signalling that the connection is not really solid. I was not able to replicate this by the time i got set up to film it

Soldered the receiver wires, got everything neat, only to realise that it’s simply the potentiometer that is busted…
Basically that thing relies on continuous contact with a semiconductor surface. And just like brushed motors, where there’s 2 things rubbing against each other, things wear out.
This vx1 lasted me close to 4 months or the better part of 3000km

interesting. I wonder what kind of life to expect from the potentiometers. yours doesn’t seem like that long.
I got over 5000km on the one this post is about before fixing the wires, and it working again.
you made sure the throttle can’t bump and move the wires around? I think a beginning to fail connection combined with moving the wires could give a similar effect.
You could hook a multimeter up directly to the throttle pot and confirm your observations that the resistance doesn’t smoothly change.

I’ve solved this by spraying contact cleaner into the potentiometer… Working just fine for the last 4 months.

Okay, inside the potentiometer:
There’s clearly some deposits there…
Also a ride after resoldering receiver:
Power hesitations still exactly there. I pushed the throttle to a fixed position and it spiked up after every single time

Fixed!
A bath in wd40 spray on the green thing, dry paper (the good shit not the kind that leaves flakes), everything put back together and hesitations are gone.

Ha. You’ll need it some day. Or at least you can refer someone to this thread when the time comes

I just fixed 2 remotes with problems.
they wires hadn’t failed but I repaired them anyway.
they had the dirty pots though:
that dinky little potentiometer kinda scares me now that I looked at it up close.
one of them:

after
not really sure this is worth doing. probably worth buying new remotes or pots.

If it helps, trampa wand has more or less the same potentiometer, and the whole setup got me to around £200
