My Micro Hydro

[JimClark]

Ok I have now received one of Randy's micro dropped sponson hydros. I plan on reinforcing the interior with a combination of wood frames and fiberglass. Never having worked on a vacuum formed hull before I was wondering about what weight of fiberglass to get? Any ides on reinforcing would be appreciated as all I have done is scratch built wood or a carbon hull that was ready for finishing.

Here is my choice
1975 Oberto

[Dr. Jet]

Oh Lord, don't let Darin see that! Next thing you know there will be a fleet of Obertos!

Thought I would give you a view that is about the same.

Oh Lord, don't let Darin see that! Next thing you know there will be a fleet of Obertos!

He just might want one

[Meniscus]

Nice. Marketing at its best!

[JimClark]

About the onlg thing I plan on changing is to modify the front of the cowl so it is 90 degrees instead of angled. Some of the drop sponson boats cowl were angled like Randy mad eit and a bunch were at 90 degrees like the Oberto is.

I already contacted Darin to see what he has that i might be able to use in the way of templates so i can make the graphic files.
going to use one of Dr Jets 3000kv brushless outrunner motor/esc $25.00 combo, a wire drive and one of Joe's micro rudders and a micro strut I got off of ebay
a 2s lipo MAH to be determined and a X430r prop as I am going to be turning left like the real boats

I also may try one of the little screamer brushless motors that has water cooling built in I have already talked to the designer about getting one

Beautiful! I bet that thing sounds like sweet thunder.

Ok, about that fiberglass, I am curious too - I have the turbine guy, but same question, weight and best resin.

Well... that explains it.. I started my own thread about this hull, but everyone is in yours!!

I am going to build this one and one of the MH at the same time with the same hardware/motors/methods in an effort to give Randy a good solid comparison between the two hulls.

That being said, I'd be interested in seeing what you come up with for wood frames. I will use one of the Doc's for the MH, but I test fit them in the Shovel and there is no way they will fit without lots of cutting/sanding/modifying. If your frames work out well, I'd might want to use them here.


On the issue of glass, I have some 3.5-4oz glass I was planning on using, have some 1.5oz glass in the mail (maybe). Doc suggested using two layers of the lighter glasses, I'm not sure if it is actually needed though. The key to these hulls is keeping them light.

My motor choice as of now:

Anyone know of any other shovels I could paint mine after? Something unique that looks.. mean.. maybe?

go to newtonmarine.com and look at page 10 and 11 for the drop sponson hulls

Thanks Jim.

I flipped through, not much jumped out at me.

Let me know how your wood frames progress. I may move my build into your thread at some point if you don't mind.

[JimClark]

The hard part is getting the top of the frames to fit. maybe Dr Jett has a trick up his sleeve on how to do that.
No problem on joining the thread

It might take me a little while. I just ordered some wood and fiberglass so I probably wont have anything for a week at least.

no worries, I'm a slow worker as well.

Anyone got any comments on that motor?
