Yep. I've found it at a car shop as well. I only use it to clean battery connectors and has served me well.

Hey guys im thinking about sharpening my rudder because ive hard of acouple people doin this.what are the advantages? Thanks

[TheShaddix]

advantages: Less drag as it cuts through water better. You'll pick up around 1-2 mph from this.

disadvantages: more prone to bending/micro damage along the thinned edge, but just keep an eye on it and maintain as needed. Always remove your rudder and props when transporting the boat.

It's just like props. The sharper/thinner the better, but also it becomes weaker, so better care should be taken.

When you sharpen the rudder, be sure to swipe it on sandpaper or a file evenly on one side and then the other with equal strokes, otherwise your edge will be shaved off asymmetrically. Then use some fine sandpaper to clean up the edge a bit more.

Also, the shorter the rudder, the less drag = more speed, but after a point you lose stability and turning becomes difficult and less responsive. I would take 5-10mm off at a time from its length and measure the speed and see how it reacts to changes. You'll see fairly short rudders on saw boats for this reason. Do your own tuning on props, rudder, stinger height and angle, center of gravity, etc. as it's fun to see the changes and will keep you more interested in your boat over time till you're ready to build a new one.

Ya i like doing all of it myself i like the time it takes to maintain it, gives me somwthing to do after this boats all dialed in i am going to build another one but now sure which boat. But thats later down the road, this boats just at the begining of its journy i still have so much i have to do. Im workin on the rudder situation still i noticed the rudder is really wobbly but i changed it up alittle and im hoping that helps.

Hey guys so now im having this issue with the boat weight. It seems to have a lean to it but its eavinly weighted could this be due to the offset rudder? Thanks

[dude123]

I am not using a bug prop though so i know its not that.

[TheShaddix]

does it lean when it's moving or standing still? How does it look when it's moving on plane? If it leans when still, your weight is off on one side which means it's the offset rudder. If it leans only when on plane, that's a different issue and could easily be a combination if reasons. Check the bottom of your rudder and try to file the edges around that bottom area to create some angle to them so it eliminates any lift. I heard it from a friend, he did that on his genesis and it helped.

As for your rudder, try using some locktite on that retaining screw that holds the rudder pin. They always come loose. Most of the wobble is from that part not being tightened.

[dude123]

It sits in the water flat and then right before it gets on plane it takes a hard lean. It also has a slight leanwhen its on plane. Im turning out not to be a big fan kf the offset rudder it seems to be causing me issue after issue. And i did that with the locktite on friday and it seemed to help alot but im still havin the issue, i cant give it full throughtle because it just stsrts to turn really bad and get the wobbles and its stickin to the water really bad so i am gonna try and move the strut up a bit and see what happens. If i get a inline rudder would that get rid of my lean issue? Thanks

[TheShaddix]

It will get rid of the lean for sure once it gets going. My friend's genesis has no lean whatsoever and he's using an inline rudder. He said he had issues with the offset too, not sure if it was the same issue though. I also get the same lean on my spartan with the offset rudder... Now it makes sense why!

[dude123]

Ok so would my best bet be to get rid of the offset rudder. And i am still having that turning problem i am going to get a better servo and redo my pushrod and go from there!

[TheShaddix]

I think you've answered your own question in your last post! I would go inline rudder for sure.

[tlandauer]

I wonder if that's because part of your bracket is in the water and giving extra drag. My MG was changed from an inline to off-set, didn't notice that, and I am even more surprised to learn that this is happening on the Spartan as i have three monos all with off-set rudder and none of them do that.
For the record, I did find contrary conclusion on the MG, mine was riding better with the in-line, very little to no wa-wa-was, but the off-set increased that----not from what I was let to believe after reading all the pros on the off-set rudder.

[dude123]

Ya i eant to comver my offset to a inline is the 4 inch extension good enough.

As long as it clears the prop.
