This is a Hydro 21 that I got from Japan this summer.!
I contacted four racers in Japan, in order to get more knowleadge about their racing.
One of the guys gave it to me for free, for me to test and understand more about the Japanese style of boats and their set up.
The boat came RTR, but no engine or pipe.
Fantastic, to say the least......we now have weekly contact and I get info from the racing in Japan.
I have used it a lot this summer with two different engines. It is pretty fast and very stable, turn fast and likes rough water.
To be continued....
