Desperado Jr

  The Desperado Jr OBL from Thunder Tiger is a catamaran speed boat. OBL means outrunner brushless motor.

This is the junior version of the Desperado.

My comments

Advantages:

• waterproof radio case protects electronic (servo, ESC, battery) from water
• magnetic hatch with drain for water removal

Drawbacks:

• the model doesn't turn well in one side despite the setting of rudder travel: steering radius is very large on one side
