Nothing?!

[forescott]

OK, I ran it a couple of days ago but wasn't gonna post anything yet until I get a video. The boat literally "leaps" out of the water on take-off and ran 40mph but needs some trim adjustment and the LVC kept kicking in after about a minute. Turns are a little sketchy(I think because the props spin the same rotation)

I turned off the LVC and should have my reverse rotation flex cables soon. I'm gonna put on my egneg prepped counter roating x442's and then give it another shot with a video. Sorry for the wait!!

Sweet! How are the temps?

[forescott]

,Well, Theres no way to check the motor temps with the outboard covers on. They are a pain in the A$$ to remove with 4 teeny screws holding them on. And I am reluctant to run without the covers especially with the ul-1 motors that have several holes in the top of the can for air(and water) to splash in. The esc's aren't even warm. Even though my under-hull dual water pick-up didn't seem to be flowing any water at all.(forgot to mention that) I already fabbed a couple of new water pick-ups for the esc's and epoxied them in place for the next run.

It looks like your props are way below the sponsons, is that correct?

[forescott]

Is there any way that adding an extra 8-inches of 12 guage wire between the motor and esc's would cause the lvc to kick in?? My esc's are tied together with a "Y" harness used for dual steering servo's with one of the red wires pulled from one side.

The prop shafts are even with the bottom of the hull right now. And I am getting a ton of cavitation already unless I jump on the throttle hard from the start.

The picture in my avatar is deceiving.

Got my reverse rotation flex cables, so now my motors are counter-rotating. Also have a nice set of counter-rotating x-442's I'm ready to try out. Had to adjust the outboards a bit negative to get the hull to plane. Gonna run it as-is to see how the setup reacts to the new props, but I'm pretty sure I'll have to drop the motor mounts down about 1/2 inch in order to bring the trim angle back to neutral. Otherwise I think it's gonna run way too wet and push the bow down. We'll see!!

any updates scott?

You need to pull both red wires and run a receiver battery pack.
This will stop your issue.

Props are to small.

You need more blade area - 3 blades.
