Thanks guy's, offer me some advise will ya, should I run 1/4" stuffing tube or because of the extra bends (s-bend), should I run 9/32" and just reduce it at both the strut and the coupler??

[Make-a-Wake]

I wish i had an answer for ya millzee, but i honestly dont........................

Use 1/4" . I use it even with minimal bend in the tube.

??? this will have an s-bend, I suppose I can just bend one up and see how free the flex is.

Why use an s-bend? Is there a specific reason? All inboard nitro boats I have ever seen have had a gentle bend from the motor to the strut.

Because of the way the struts are mounted in comparison to the motors. Iknow it's a little late to ask but couldn't you mount the struts closer together or will it effect your prop size? Great job on the build btw.

Nice build bro

[millzee]

thanks mate, I hope to get the stuffing tubes in and seal it all up over the next few days so I can get it wet, I'm a bit excited.

Ok, today it's raining out side, my wife is home and happy to run the office so it's off to the shed I go.
I now have a couple of the 240amp Aquastar speedo's to use instead of the t180's so I'll play around with the layout again and make sure my cog can adjust from 29+%.
I through it on the scales before fully loaded and it look's like fat cat is back, 8.5kg's with no lid, how's that weight??

[millzee]

It's been a great day, I managed to get plenty done but for now I'll only show a few pic's as I need sleep.

I like it very much...... Why weren't you able to get the J bend ? Not enough hatch clearance ?....... I did a simullar build with a conquest and was barely able to scweek J bends, I also was able to do 5" motor spacing to keep prop wash off rudder...... Mainly wanted to tell you that the fella who bought the boat is 100% happy with the twin 1717, T180, 6s 4p setup and has had zero issues with 3/16" cable thrusting with the struts via octura thrust washers....just wanted to let u know mate keep the thrust at the transom so your motors don't lift your boat and add load to the cable doggy .... If you haven't seen the twin conquest get at me and I will link you up ! Enjoy

Ran like a champ first go out..... I keep in contact with the owner and he says he can do 60mph full speed turns on 6s.... First run , you may have seen this.... http://m.youtube.com/watch?v=9BGu9LH-rOM

Oh and the wieght is without batts? My conquest quad drive with 6s 4p 20000mah was 22lbs and plained up good....

[millzee]

I did see that one, good job, thanks for the tips. I'm going to do the stuffing tubes this afternoon, then I can focus on the hatch seal, electronics and then I should be able to pull the pin, excuse the pun. I was a tad concerned with the 180's in a hull that size so the 240a aquastars will give me a little more piece of mind.

[Rumdog]

Great job! The Aquastars will be great. They won't even break a sweat with that setup. I may have missed it, but are you starting with C/R x447's? Do you have any props yet to try out on her?

I'll be converting my gasser Sprintcat this summer with a single drine and 5692 Leo.
You're gonna love the sprintcat!
