Thanks, I don't think I going to put a cage on this one. This is more of an experiment, maybe if it runs well i'll put more into it. I just hope between the front spoiler and drag of the rudder it stays in the water.

Nice....very nice! Don't forget the video of the maiden run. How are you going to test the airfoil?
Make a speed run without it and check the top speed at blowover, then put it back on to see if you can go faster?

Hopefully I'll get it in the water tomorrow, the weather is not cooperating today. Thanks for the tips.

Great looking boat. That will sound awesome when it is running. Hope you can take some vids when you go for your first run.

Nice boat!

I love the sound of twins. Especially the smaller displacements. A good friend put twin OS32's on one of my SI's and it sounded like a formula car on the water. [link=http://www.youtube.com/watch?v=8qKW3IfKpHc]Here [/link]is a link of it running.

Looking forward to hearing yours run!

That's a great video! That sounds awesome! I think I going to put two braces across the top between the engines like the one in the video. It can't hurt.

Thanks.

Have you run your boat yet?
Any chance of getting a video of it? ....at least on the bench to hear the twins?

I just finished running the braces between the engines. Tomorrow morning I'll wake up the neighbors with a bench test and it will be on video. If everything looks right, we'll hit the water.

Music to the ears.
It sounds like one of them is a little rich at WOT though.

I think it's the left one. I didn't have alot of time to mess with it this morning, had to go to work. I'll mess with it some more tomorrow.

I think the battery in my electric starter is going bad. It seems to run out of juice really fast. What size battery are you guys using?

Here's a link to the one I have. The battery is 12v 1.4ah. http://www3.towerhobbies.com/cgi-bin...&I=LXJC35&P=ML

What are some starting tricks for nitro's that you use?

Any input will help.

Thanks,

Ryan

Go and buy a $20 lawn tractor battery. I charge mine once at the beginning of the season and once mid-season.

If you want, I have plans for a field box that I designed you can have.

Well guys it ran a little slower than expected with the flat bottom and 9x6 props. I updated the hull a little and added 10x6 props, hopefully we'll see a performance gain.

Dang....That rudder seems long. Could you have too much drag from the rudder?

Thought about that. Probably could cut off an inch or two.
