yea the boat is just to light with a bunch of HP on the thing.. It can be done but not for the faint at heart.
My Piped S1 is one of the best running tunnels i have but i have kept the power moderate to complement the hull… not over power it.
I still like to run my S1s with a sport motor best. 48-50 is nothing to sneeze at when it comes to a sport hull. The Villain S1s light weight and light ride are the cats tail when it comes to low power.
The new boat (Nemesis h34r: ) will address the high power motors..
