Walkera lama 400 just spins
The walkera Lama has a bad gear setup,there are two tiny screws on the top
gear which powers your bottom blades one on each side of the outer shaft
if these two screws were not properly tighened at the factory or you ran yourLama
400 into the ground even if it was at a slow rotation when the bottom impacts
the ground the bolts shear off the outer shaft and you no longer have 100%
power to those blades,if your helicopter spins clockwise and you tried every
thing,this is the problem,replacement is required or you can tear it all down
and drill and tap two new holes with new screws,these are machine screws
and are less than 4/40 which is very small.To check hold top gear with two
fingers left and right side of gear and turn the bottom blades only,if the blades
turn your shaft to gear screws are sheared off

I have a new walkera
you have a problem with your rear rotor assembly.
if your rear rotor shaft is broken or the gear is the copter will spin around and around.
or, if these parts are not broken then your trim needs adjustment or, you need to learn to fly and control the rear tail rotor so it does not spin around. Thats your answer. firstname.lastname@example.org

What could be the problem
When the throttle starts failing this way it is a sign of either a failing contact or batteries. But since you said the batteries are fully charged then we can eliminate the batteries out of the equation.
The throttle contact does not make as much contact as it is supposed to and therefore starts up the rotors and then does not continue giving as much power as it is supposed to.
There could be a power flow breakage or a partial contact somewhere hence the initial startup and the stoppage.
Hope this solution has been helpful?
