1/6 scale Jetsprint boats and 30mm Jet drives

[flraptor07]

Mick it looks to me like it was running a little better in the last video then this one. It also looks like you need to get the CG futher forward.

Hi guys,
That is exactly what i was going to do, the other thing that may be happening is that the unit may be a little too efficient, sucking the back down ????
Dont worry , i have no sold any more hulls and will not untill i get it all sorted. The progress on the Marathon hull files are about half way too.

How's the boat doing at slow to medium speeds? It looked well planted until it started running fast. It would be great to see it operating through all the ranges rather than just fast. Most of the running I will do in moving water will be at lower speeds. If the boat is doing everything other than fast well at the moment why not show those speeds off. A jet boat wasn't something I was going to add to the speed arsenal anyway!

the boat runs well at slower speeds, i will post a video once i get a hole in the bottom fixed, largely due to me putting it up the bank into a large rock.
cheers.

Hi Guys,
Gave it another run today, think i may have got the porposing sorted, still does a little bit at high speeds but i thyink i know how to sort it i will post some video tonight, and yes there is also some slower speeds too.
I am confident enough to release the hulls for sale now.
See for your self
Regards Mick

Ok here is the latest video, I am confident that all that remains is to move the battery a little further forward and adjust the trim a little more. But is a vast improvement even from last run.
Enjoy

Hi guys ,
Just thought you would al like to know, I am very fortunate enough to announce that these units and hulls are now available thru OSE, The hulls are soon to be in stock, just have to re machine out the lower plug and remold it, but they will not be very long at all.
Stay tuned, I will be reposting another video tomorrow night on the modified hull this time I have removed all the lifting strakes.
Regards Mick

Hi guys, some good news, had a very successful run today, a combination of removing the lifting stakes plus putting an extra battery up in the nose got it going like it should. So I will redo the plug, bottom mold, and finally I am going to release the hulls for good.
I am waiting for a mate to upload the video, he said he was going to load it tonight
I still have 2 hulls in the mold from before, if anyone is willing to sand the stakes, I am prepared to sell these for a reduced price.
Regards mick

Heres the run guys, the second part is where I put a spare battery up in the nose, Now I am happy with it. Not too sure yet but I may even make a slightly larger hull for this unit, but that will be a while down the track. I will get some more MDF and laminate it this week, and hopefully rout out another plug for the bottom this week, then if all goes well will get it ready for molding next weekend.

That's much better Mick, You got it now! If I'm not mistaken these hulls are designed to run in shallow water and I'm sure ground effect would be a factor in how the boat runs if you were running it in shallow water. Just like a Airboat, they run like crap in deep water.

[mickieb49]

Yes you are right about these are designed to run in shallow water, as such they are designed to ride high when they are under power, the problem I have is that there is maybe a little too much power for this hull, all the same, this is not a bad problem....
The trick is to make them run well in all conditions....
I should be starting the plug for the marathon hull very soon, so I will have to go thru all the set ups again ...
Have you got your jet unit yet Mike?
Regards Mick

Hiya Mickie, I wanted to drop you a line because I thought you may be interested in a possible collaboration deal with this dude.

He's thinking of the jet pump from Hobby King for his 1/4 scale aluminum boats, I thought you may be able to offer him a more viable solution. This is the pump he's thinking about .

I can get his contact info for you if you like.

Thanks Jim, i may drop him an email.
