thanks
Ron, there are a lot of factors that can come into play. Driving style, etc., all come into play.
If you are our running around, making a lot of tight turns, using partial throttle a lot (like when you turn the ESC down to logarithm... you are only getting 80% throttle), the boat won't be running as efficiently as it would if it were flying fast and loose.
My setups are for racing. Long straights, followed by 35' radius turns, all usually at or near full throttle, and the boat running as light as practical.
Anything less than this, and you'll need to detune some.
In my experience thus far, with this hull, and with this motor, is that it can be run all day long on the stock prop when setup correctly. As you start to tune it up, and make it faster, temps will build. Of the props I've tested, the 42x55 seems to be a good compromise for speed vs. temps, but even that is going to take away some run-time. The X642 should perform well, but it has more pitch yet, (67mm vs 55mm), so it may further reduce run time and increase heat.
