It's a Kyosho bluestreak 800GP
And basically the rear is an outdrive setup where the prop turns with the rudder

And the U joint there gets warn out way too quick, like in a couple of hours of running or so.
So I want to put a different rudder on it, and get the prop to be stable and not turn with the rudder
But I need a longer prop shaft for this
And just wondering if I should go a flex shaft? and just leave the setup that is on now?
What kind of angle can a flex shaft take?
