Hi,

as the littel twinoutborder runs well i have started to build a bigger one to get a lot of trust .

The skeg is now bigger but i want to trim it down to get less drag on the straight.

Hi Christian,

Great idea that would allow easy adjustment of thrust depth & thrust angles. What size are the motors & what hull is it designed for?

Hi Jim , Andy,

have bold on the back of the Prather tunnel . Have to install all the gearing and then it has to run . It looks good so it will race. But give me some time as i have also to finish my sons belly tank racer .

Jim, motors are Scorpion 4025 / 890kv .

by the way , have you seen the Yanmar petrol outbordmotor with two counterrotating crankshaft ?

Build one motor and have the counterrotating propellers by this way . Very clever design in my eys.
