Project Fast Cat

Got some updates. I decided to go ahead and make sure the sponsons were flat. They were hooked a little. Straight now...




My servo arms came in today. I couldnt decide between black or polished so I ordered both.

Here's the silver




Then I ran into a snafu. The fitting in the right is too short to go through my thick reinforced transom. So I had to make something on my lathe to work. Drilled the hole already at this point. This is where my steering linkage passes through.




And installed.

Then I ran into another problem. I made up the linkage rod. Because I had a few bands in it, it would flex particularly in the pass through area. I even went through the trouble of ordering 3/32" stainless rod which is really stiff (nobrust either) but it still flexed. I tried to heat treat it. Didn't work. So what do I do? After a little thought and looking at where the flex was....I decided to made the pass through hole smaller. Mid I use metal it may be noisy and rough, so I made a nylon insert. The insert does not let the rod flex at this point....which is the only point it was flexing....it's now unbelievable how it has literally no slack.

And sealed better

It's not really sealed right there. There is about a .010 gap but there's a boot that goes over the fitting not shown. Positive side is if the boot gets torn, it will take much longer to fill with water. I'll be doing this for now on. I just ordered some nylon rod

You should try Titanium turn buckles by Hanger9 . I'm using a 5" 4-40 one on mine . You can bend them a little to if need be.image.jpg

That would be great but the length of the rod is bout 9" and has several bends. In a mono or cheetah where you have easy acces and a straight shot possible to the rudder, that would work well.

They have long ones ! 7", 6" , 5" clear down to 1 1/2" or 2". You could put them together with a small collar .

What if I just buy some 3mm titanium rod? It does not need to be threaded. Would that be stiffer than the 3/32 (2.381mm is what it converts to) stainless rod I'm using from k&s metals?

I have made stiffer rods just by sleeving steel rod with cf tubing bonded in place. The shorter linkage no worries with these turn buckles.

I looked at the 2 props I got from you finally . They are nicely done ! Not overly thinned and sharp ! Good job . I'm sure your even better now lol

I am lol. Ive been getting dasboata to do most of my props here lately because I havent had time. Takes me way too long to do one and i get bored easily. I did consider the cf sleeve thing but that would likely not be an elagant solution for me as the straight part that needs stiffening protrudes outside the boot. What ive done as of now is actually a very good solution and its simple and works very well. I have literally no flex.

Sorry to interject here fellas but where are these longer rods? I found up to 5" which just may do me but...

I get them at my local shop.... I checked there site and it only said 5" so I would call them and find out because I'm certain I seen longer ones.

I'm so excited. My battery trays came in today. I worked with Monojeff on designing some trays that would be CNC cut and fit perfectly. He did a excellent job and had them to me with the quickness!


Store bought on left....too wide to fit the Rivercat.
