for eec community , i guess the corally SP12M would be top choice,
cheap and easy to get parts in europe. the sp12 has the strongest chassis low cg bottom t-bar hassle free battery holder , solid rims wont wobble like AE wheels , arms are made of carbon fibre you can fabricate your own if broken. you dont have to remove top plate to remove motor.
that 's all the + point if you are in the EEC.
