Marcio Canzian Posted March 27, 2018 Share Posted March 27, 2018 A friend of mine had a strange problem with V8. He said he was riding slowly and suddendly when he passed over a hole on the street, V8 got unstable and tilted back. He did not fall on the floor, but he is worried. Has somebody ever had this report before? Link to comment Share on other sites More sharing options...
WARPed1701D Posted March 27, 2018 Share Posted March 27, 2018 What was the battery level and how heavy is your friend? If the battery was low then the voltage dip caused by the wheel drawing excessive power to pull itself out the hole could have dropped the voltage below 3.4v. This is the voltage the wheel considers to be 0% charge. At this point the wheel will enter extreme and unridable tilt back until such time as you cycle the power and the battery voltage recovers or is charged back above 3.4v. If sounds were turned on then it would have said 'low battery' as this happened. The V8 is only a 2 parallel battery configuration. Ampage draws (and thus voltage dips on lower charges) can therfore be exaggerated under abnormal situations. The V8 is an awesome wheel but is only a mid level specification device.

meepmeepmayer Posted March 27, 2018 Share Posted March 27, 2018 2 things I can imagine: Low battery, then that tiltback was only natural. With (possibly) all wheels, there seem to be (very rare) cases of the gyro sensor going crazy after a sudden bump, but usually this results in oscillation instead of tiltback. But in theory it could have been something like this. Link to comment Share on other sites More sharing options...

I think It was not really at the and of the drum. I will check it better! Link to comment Share on other sites More sharing options...
