   Yes, the engine has a direct drive to the propeller. When sailing, the engine runs at about 20 - 40%, so it doesn't heat up. The boat is not a racing boat, it's good to sail slowly.
   I'll probably use the gearbox on a new 1:7 model - I don't know yet. I'll keep you posted.

   Thanks for the reply Premecekcz.
   The ride is great, the electric motor pushes well.
   Does it heat up with a 50 mm propeller or not?
   I guess you don't use a mechanical gearbox, did you prefer a direct connection to the propeller shaft?

   The engines are 2x MIG G650. At 12V voltage about cca 3000 rpm. Propeller 50mm.
   It is true that at full throttle the ship would sail too fast - by the standards.

   Hi Premececkz, what motor did you use for this model?
   Do you have any factory data such as voltage, operating or stall current, power, rpm, etc.etc.?
   What diameter is the propeller?
