Hi Kaptain

I m Yoda

If you are only interesting by a static model, yes, this model is very cheaper, approx 25/30 euros.

But, the hull is not the most expensive part, count all requiere equipement ( 3 micro servos, micro controler, micro receiver, pump...), cnc milling the special water tight cylinder ( i have paid approx 150 euros for the tube).

There is a big difference between a static model ( on the table) and a fully fonctionnal radio control model.

The transmitter costed arround 125euros... and it is include in my offer.

I think we don't speak about same modeling
