I don´like words like "speed limit" =)
There is room for another 1 kg in that hull. So I´m thinking about a bigger motor and bigger batteries.
That should help making this thing go faster.

Currently it runs with approx. 35k rpm and a 36 diameter prop. Mr. lehner drove this thing with 50k rpm and over 90 kph!

...this boat will go faster - I hope =)
