Need Help With Walkera Ladybird V2

[chixter57]

Had a crash, fractured the cage (a weak point imho)...put the receiver board onto a new cage as I have done before with no problem. Now, the coptor will take off but pirrouette uncontrolably. If I give it opposite rudder it just spins (fast) in that direction....no mount of trim will help. Also if I throttle down, then throttle up, it changes the direction of the spin. I think perhabs I should erease and re-bind this unit but I dont have the manual. It is the Version 2 with the Devo-4 (sucky) transmitter, but this thing is fun. I chase the chickens in the bakyard with it. Any help would be appreciated.
