What was reported
Exact unit label lost. One of the 2023–24 Walksnail Mobula8 returns, where we confirmed a faulty gyro with heading drift: uncommanded yaw (sharp left twitches or slow drift) and the heading creeping in Betaflight while stationary.
Our take
Looks near new; not powered up by us. Check the Betaflight setup tab for heading creep. A replacement Mobula8 AIO fixes a gyro fault and keeps the Walksnail VTX/camera, motors and frame.
Repair hint
Check heading drift in Betaflight; replace the AIO if the gyro is faulty.

Are you looking to buy LUCKY DIP · Happymodel Mobula8 85mm Walksnail (ELRS): Likely Gyro / Yaw Drift, Sold As-Is in Australia?
LUCKY DIP: faulty customer return, sold as-is. No returns, no warranty.
This listing is for one returned Happymodel Mobula8 85mm 1-2S HD whoop, Walksnail version, with ELRS. It looks pretty much new and has been on the returns shelf since it came back.
How the price works: it starts at $200 and drops every night at midnight for 30 days, down to an $80 floor. The floor price only lasts 24 hours. If nobody grabs it, the price goes back up to $200 and the 30-day countdown starts again. Wait too long and you could miss it, or have to wait another month.

What we know
The label for this exact unit didn't survive, but it's one of a small batch of Walksnail Mobula8 returns from 2023–24. The fault we confirmed on those was a faulty gyro with "heading drift": the quad yaws by itself, sometimes a sudden sharp twitch to the left, sometimes a slow continuous drift. On the bench, the heading in Betaflight creeps steadily even with the quad sitting still.
Our take
- It looks near new, and nothing's visibly damaged. We haven't powered it up.
- Most likely fault: the gyro on the AIO flight controller. Check the Betaflight setup tab: if the model slowly rotates while the quad sits still, that's it.
- Could score: a replacement Mobula8 AIO fixes a gyro fault, and you keep the Walksnail VTX and camera, motors and frame. Some pilots also report recalibrating and filtering helps marginal gyros.
- Worst case: great parts: the Walksnail camera/VTX alone is worth a big chunk of the price.
