convulse = low battery

yes , it is tricky to slow turn without stalling ,adding a link on tracks really helps to slow motion,but tend to change track alignment on the rear idler on rocks or obstacle

- if you push 3 seconds on controller , it will turn(or try to turn) for 3 seconds, that is how you got the feeling
that it continues for few seconds(3s) understand ?

maybe you dont charge your battery enaugh ,
if you have a 1700mh with a 400ma charger you should devide 1700 / 400 = 4.5 hours for charge, me i add 0.5 hours more to be fully charged.
