I got both Nitro Vee and Nitro Hammer.

Nitro Vee :
The speed is 20+ out of the box without any modification.
The cooling system needs to modify.
No water-proof radio box for receiver and servos.
It is not easy to get on plane.


Nitro Hammer:
The speed is 30+ out of the box without any modification.

Yes, the rudder is very easy to break apart.
Buy a couples of spare rudders or replace the original rudder with metal one.

Don't make a sharp turn at full speed, it flips.


Happy boating.
