Hi Guys,
Thank you all for your advise, especially WolstonFlyer & PeD.
The 120SR, balanced main blades, nearly all the vibration has gone.
There's barely any moving around on take off, TBE has all but gone, still goes into TBE but opposite rudder will stop it.
Have now had loads of flights, and she's still in 1 piece, and undamaged.
Just need to take the Flybar off, to check it's balance.
The Syma S031. Have had both sets of blades off and balanced, also the flybar.
Have put a 1 Pound coins worth of Blutac inside the nose, and she has flown well for a full 7min flight in the living room.
Balancing Blades, Flybars is worth while.
Regards Trevor
